An Assessment of College Students' Attitudes and Empathy toward Rape
The purpose of this study was to assess rape attitudes and empathy levels of students at a university in North Texas. The Attitudes Toward Rape questionnaire and the Rape Empathy Scale were administered to 387 undergraduate students. Dependent variables were attitudes and empathy and independent variables were prior knowledge or experience as a rape victim, having female siblings, gender, marital status, and age. Significance was found between rape-intolerant attitudes and both prior experience as a victim (p < .001), and gender (p < .001). Significance was also found between empathy and experience as a rape victim (p < .035) and gender (p < .032). digital.library.unt.edu/ark:/67531/metadc279015/
The Effects of Project PACE on Adolescent Females' Physical Activity Readiness
This study evaluated the effects of Project PACE, a program designed to increase physical activity, on the physical activity level and selected psychosocial variables of sedentary adolescent females ages 12 to 18. Psychosocial variables included self efficacy, attitude, perception of barriers, perceived social support, and knowledge. Of the 69 participants, 40 were enrolled in the treatment group and 29 were enrolled in the control group at the start of the study. The only significant differences were found for attitudes towards physical activity at base line. Findings from this study suggest that implementation of Project PACE protocol in school settings may produce some positive effects, but no significant findings were detected. digital.library.unt.edu/ark:/67531/metadc279267/
Do American Adults Know How to Exercise for a Health Benefit?
Approximately 950,000 Americans die annually from cardiovascular disease. Physical activity is a major risk factor for the development of CVD and a risk factor for stroke. The purpose of this research was to determine whether American adults know how to exercise to achieve health benefits and whether this knowledge is a function of demographics. Items included knowledge of exercise guidelines and knowledge of traditional and non-traditional exercise activities. This information was obtained from 22 questions that were a part of a larger national survey of 2,002 American households. Statistical analyses of this sample, indicate American adults have knowledge which varies by demographic groups. Data revealed that overall the 61+, Less than High School, African-American, Hispanic-American, and Male groups have the least amount of knowledge about exercise. These data can provide health educators with important aspects of exercise knowledge for future health promotions/interventions. digital.library.unt.edu/ark:/67531/metadc278934/
The Significance of Time to Exhaustion at the Velocity at VO2Max
There were two primary goals in this investigation. The first goal was to determine if inter-individual variability in time to exhaustion at the velocity associated with V02max (Tlim at Vmax) was explained by anaerobic capacity (AC), Vmax, anaerobic threshold (AT), and/or a combination variable in the form [AC • (Vmax - vAT)^-1]. The second goal was to determine if AC could be predicted from Tlim at Vmax, AT, and/or a combination variable in the form [Tlim • (Vmax - vAT)]. digital.library.unt.edu/ark:/67531/metadc278993/
The Development and Validation of the College Student Attitude Toward Female Victims of Domestic Violence (CSAVDV) Scale
The purpose of this study was to develop and validate the College Student Attitude Toward Female Victims of Domestic Violence Scale. Procedures used were a 12-day test-retest for reliability, experts assessment for face validity, and a principal component factor analysis for construct validity. Cronbach's alpha for test-retest reliability was .86. digital.library.unt.edu/ark:/67531/metadc278253/
Muscular Differences Between Female Power and Endurance Athletes
The purpose of this study was to compare the torque generating capabilities and fatigue responses of female power athletes, female endurance athletes, and age-matched female non-athletic controls. digital.library.unt.edu/ark:/67531/metadc277604/
College Students' Attitudes toward Pregnancy and Women in the Work Force
The purpose of this study was to assess college students' attitudes toward pregnancy and women in the work force following the passage of the Family Medical Leave Act of 1993. Data were obtained from 347 students at a university in North Texas during the spring semester of 1997. Gender, age, employment status, parental status, and citizenship were independent variables hypothesized to influence attitudes toward pregnant working women. Gender was significant for the following factors: pregnant women as employees (p<.001), emotional stereotypes (p<.001), choosing family or career (p<.001), and physical limitations (p<.001). Those students 17-19-years-old had a more negative attitude toward pregnant women choosing work over family (p<.001) than did the older students. digital.library.unt.edu/ark:/67531/metadc278342/
Effects of Endurance Intensity and Rest Interval on Subsequent Strength Performance
The purpose of this study was to examine the acute effects of cycling exercise at different intensities and rest intervals on strength performance. Ten males, engaged in concurrent training for at least one month prior to testing, comprised the subject group for this study. Results show only leg press torque and leg press work to be decreased after cardiorespiratory exercise of moderate intensity. Leg extension average power, chest press torque, chest press power, and chest press work after cycling were not decreased from pre-exercise values. No significant effects were found for exercise intensity, testing times, or intensity by testing times. These results indicate that lower body strength is decreased by cycling and that one hour is not sufficient to restore leg strength. digital.library.unt.edu/ark:/67531/metadc278409/
Social Control and Self-Control Factors Associated with Interpersonal Violence in Adolescent Females
Adolescent females are committing an increasing number of violent interpersonal acts. This study used the qualitative technique of focus group interviews to explore social control and self-control factors which impact such behaviors. Forty-seven girls aged 10-18 years described situations and events where interpersonal violence might be used and also what might prevent such acts. For the girls interviewed, social controls were the predominant means of controlling the use of interpersonal violence. Family and peer groups were the most powerful social controls, whether positive or negative. Self-control was deemed important but most girls lacked either the skills or desire to engage in self-control. Violence prevention programs need to teach techniques for improving self-control and increasing self-concept to be most effective. digital.library.unt.edu/ark:/67531/metadc278635/
The Effect of Running Speed on VO2 Kinetics in the Severe Exercise Domain
There has been an interest in the kinetics of the V02 response during exercise at various intensities. However, most studies focus on the response of submaximal intensities whereas few studies have examined V02 kinetics at severe intensities. The purpose of this study was to evaluate the effect of exercise intensity on V02 kinetics over a range of severe intensities. digital.library.unt.edu/ark:/67531/metadc277817/
The Effects of Video-Computerized Feedback on Competitive State Anxiety, Self-Efficacy, Effort, and Baseball Hitting-Task Performance
This study examined the effects of frame-by-frame video-computerized feedback on competitive state anxiety, self-efficacy, effort, and baseball performance of high school players. Players were randomly assigned to one of three feedback conditions: (a) Hitting score, (b) Hitting score and frame-by-frame analysis of a mechanically correct swing, (c) Hitting score and frame-by-frame analysis of participant's swing and a mechanically correct swing. Once per week for six weeks, the players completed three questionnaires: (a) Hitting Self-Efficacy Scale, (b) Competitive State Anxiety Inventory-2C, and (c) Performance Effort Scale, and performed a hitting task. Results of the 3 (Group) x 6 (Trials) ANOVAs revealed no significant effects. This study does not support previous confidence-baseball hitting research. digital.library.unt.edu/ark:/67531/metadc278280/
Soul Line Dancing Among African American Women in the Church: an Expectancy-value Model Approach
Guided by the expectancy value model of achievement choice, this study examined the relationships among expectancy value constructs (expectancy related beliefs and subjective task values), effort and intention for future participation in a culturally specific dance, soul line, among African American adult women in the church setting. Participants were 100 African American women who were members of the women’s ministries from four predominantly African American churches in the Dallas/Ft. Worth metropolitan area. Participants completed a 20-minute soul line session and responded to survey questions, validated in previous research, assessing their expectancy-related beliefs, subjective task values, effort, intention for future participation and physical activity. This was the first study to use the expectancy value model as a guide to determine motivations attached to physical activities among African American adult women. Usefulness, a component of subjective task values, emerged as a predictor of intention for future participation. Eighty-one percent of the women did not meet physical activity guidelines for aerobic activity. Of those inactive women 60% indicated an interest in doing soul line dancing often at their church after one short exposure to the activity as indicated by the strongest possible response to both intention questions. A slightly smaller percent of the active women provided with a strong positive response for future intention. These findings suggest that soul line dancing is a practical avenue to increase physical activity among African American women in the church. Future research should test this theoretical model on a wider variety of individuals who are sedentary to physically active, measure actual participation, and directly measure BMI and physical activity. digital.library.unt.edu/ark:/67531/metadc149658/
Implementing a Physical Activity Centered Education Program for Individuals with Brain Injury
Research has shown that health promotion programs (HPP) that incorporate education about physical activity (PA) are one mode of rehabilitation that can improve the health of individuals with disabilities. However, education-based PA curriculum is not included in the rehabilitation program for individuals with a brain injury, indicating a gap in services provided. Consequently, the purpose of this study was to create and deliver a physical activity centered education (PACE) program that supplemented the existing rehabilitation program for brain injury. PACE consists of an 8-week (16 session) program aimed to (1) increase self-efficacy for being physically active of PACE program participants, (2) increase PA stage of change in PACE program participants or the maintenance of adequate level of PA, and (3) improve the rehabilitation outcomes (i.e., abilities, participation, adjustment) of PACE program participants. Based on previous research, it is hypothesized that participation in PACE will result in (1A) increased self-efficacy for PA, (1B) greater self-efficacy for PA than the standard of care group, (2A) increased readiness to be physically active, (2B) greater readiness to change their PA behavior than the standard of care group, (3A) improved rehabilitation outcomes, and (3B) greater rehabilitation outcomes than the standard of care group. the PACE program resulted in: (1) an average increase of 19.36% in participants’ PA self-efficacy (effect size [ES] = 0.37), (2) 15 of the 22 PACE participants (68.18%) reported readiness to engage in regular PA , and (3) an increase in rehabilitation outcomes (i.e., abilities, adjustment, and participation)In conclusion, the PACE program can improve PA self-efficacy, readiness for regular PA behavior, and improved short-term rehabilitation outcomes. digital.library.unt.edu/ark:/67531/metadc115184/
Limiting Disability Post-Brain Injury Through a Physical Activity Centered Education Program
Brain injury (i.e., traumatic brain injury, stroke) is a considerable public health issue due to complicated outcomes of the injury, increasing incidence, and high costs linked with medical treatment. Rehabilitation centers are challenged to help individuals manage the resultant associated conditions and prevent secondary and chronic conditions. Research has shown that health promotion programs (HPP) that incorporate education about physical activity (PA) are one mode of rehabilitation that can improve the health of individuals with disabilities. However, PA is not included in the rehabilitation program for individuals with a brain injury, indicating a gap in the services provided. Consequently, the purpose of this study was to create and implement a physical activity centered education (PACE) program within an outpatient rehabilitation program. PACE consisted of an 8-week (16 session) program which aimed to (1) increase PA self-efficacy, (2) increase intention to change PA behaviors, (3) increase amount of PA completed regularly, and (4) promote positive rehabilitation outcomes. Based on previous research it was hypothesized that participation in PACE would result in (1) increased PA self-efficacy, (2) forward progression in intention to change PA behaviors, (3) increased amount of PA completed, and (4) improved rehabilitation outcomes (i.e., abilities, adjustment, participation). The PACE program resulted in an average increase of 16.1% in participants’ PA self-efficacy (effect size [ES] = 0.41), an increase from three of nine participants at pre-test to six of nine participants at post-test reporting to be in a stage of change in which they are most likely to be successful in regular PA participation (i.e., action or maintenance), and a comparable improvement in MPAI-4 scores (rehabilitation outcomes) after discharge to a rehabilitation program without a PA education component. In conclusion, the PACE program can improve PA self-efficacy, intention to change PA behaviors, and short-term rehabilitation outcomes. digital.library.unt.edu/ark:/67531/metadc84224/
Resilience and Health Outcomes in Patients with Traumatic Injury
Due to the increasing healthcare costs and reduced length of hospital stay it is becoming increasingly important to identify individuals who are ‘at risk’ of experiencing long-term health issues. The purpose of the study was to: (1) determine if resilience, self efficacy and depression changed from inpatient to 3-month follow up; (2) examine the relationship between resilience, self efficacy, depression, and quality of life (social roles/activity limitations) at inpatient and 3-month follow up; and (3) identify if resilience at inpatient is related to change scores in selfefficacy and depression at 3-month follow up. Results from the paired sample t-test indicated that participants did not experience a significant change from inpatient to 3-month follow up in resilience or self-efficacy, but a significant decrease in depression was observed. Findings also indicated significant correlations between resilience, self-efficacy, and depression during inpatient stay and resilience, self-efficacy, depression, and quality of life at 3-month follow up. However, there was no relationship found between resilience and change scores in self-efficacy and depression. Future resilience research should continue to identify the variables that are most strongly related to resilience so effective interventions can be developed that improve rehabilitation outcomes, decrease secondary and chronic conditions as well as aid in the successful reintegration of individuals into their lives after a traumatic injury. digital.library.unt.edu/ark:/67531/metadc84187/
Mechanisms Affecting Bench Press Throw Performance while Using a Counter-Balanced Smith Machine
The use of a counter-balance weight system of a Smith machine affects measures of bench press throw performance. Twenty-four men performed bench press throws at 30% of their one-repetition maximum under four different conditions: 1) counter-balance and rebound movement (RC), 2) no counter-balance and rebound movement (RNC), 3) counter-balance and concentric only movement (CC), and 4) no counter-balance and concentric only movement (CNC). Peak power, force, and concentric and eccentric velocities were measured using a linear accelerometer; and peak ground reaction force (GRF) was measured using a forceplate. Peak measures for concentric and eccentric velocities showed that NCB> CB and RBT > CBT. Peak GRF measures showed CB > NCB and RBT > CBT. The lower performance measures for CB were likely due to an increase in the net external load when the barbell accelerates faster than the gravitational constant causing the counter-balance weight becomes ineffective. digital.library.unt.edu/ark:/67531/metadc67963/
Self-Efficacy and Fears of Pain and Injury in Gymnastics and Tumbling: Does a Previous Injury Matter?
The purpose of this study was to explore whether a previous gymnastic or tumbling injury influences gymnasts' and tumblers' self-efficacy, motivation, competition anxiety, and fears of pain and injury. Participants (N = 105) completed survey packets during practice which contained demographic questions and questionnaires that measure self-efficacy for physical abilities and exercise, self-motivation, risk of injury, pain catastrophizing, and sport anxiety. Results of a one-way ANOVA indicated that gymnasts and tumblers who experienced a previous injury were significantly different than those who had not experienced an injury on their self-efficacy for physical abilities (p = .007), self-motivation (p = .007), and perceived risk of reinjury (p = .018). Specifically, these findings indicate that gymnasts and tumblers with previous injuries experience higher levels of self-efficacy for physical abilities, self-motivation, and perceived risk of reinjury. Implications for coaches, gymnasts, and tumblers include: creating an open and comfortable environment to discuss pain and injury, developing strategies to break the negative cycle of fear of injury, and fostering a positive rehabilitation process. In the future, researchers should examine the influence that gender and type of competition has on self-efficacy, self-motivation, perceived risk of reinjury, pain perceptions, and competition anxiety of those who have experienced sport-related injuries, as compared to those who have not experienced these types of injuries. Researchers should also examine how the type of injury, whether it is a first time injury versus a reinjury, influences perceptions of pain and fears directly following the injury. digital.library.unt.edu/ark:/67531/metadc33172/
Identifying Changes in Resilience during Rehabilitation from a Spinal Cord Injury
The study purposes were to identify changes in resilience, satisfaction with life (SWL), depression, spirituality, and functional independence (FI) and to examine the relationship between these variables, during the inpatient rehabilitation for a spinal cord injury (SCI). The sample included 42 individuals with a SCI, 33 males and 9 females, who were inpatients with a mean stay of 52 days (SD = 15.78). A repeated measures design was employed with questionnaires completed at three times during rehabilitation. Results indicated that there were significant changes in depression, satisfaction with life, spirituality, and FI during inpatient rehabilitation. Findings also indicated significant correlations between resilience, SWL, spirituality, and depression. Future studies developing interventions, and examining factors that predict resilience could help build resilience and may improve rehabilitation outcomes. digital.library.unt.edu/ark:/67531/metadc6039/
Minimum levels of physical activity and perceived quality of life.
The purpose of this study was to examine the association between engaging in minimum levels of physical activity as defined by ACSM and perceived quality of life. A total of 43 college students were included in a repeated measures, quasi-experimental design research study that produced an overall retention rate of 65%, which resulted in 15 students being placed in the treatment group, and 28 students being placed in the control group. Analysis of variance with repeated measures was used to compare the quality of life mean scores over three administrations of the Quality of Life Inventory (QOLI), which resulted in no significant main effects for either the time measure or the group measure, but did produce a significant interaction effect. Post hoc analyses showed there was a significant difference between the treatment and control groups' quality of life mean scores only during the second administration of the instrument. Further analysis showed that the control group had significantly higher quality of life domain scores for six of the 16 quality of life domains. There were no significant differences between groups across any of the physiological measures. These findings did not support previous research that increasing individuals' level of physical activity will enhance their perceived quality of life. Instead, this study only provokes more questions about the connection between physical activity and perceived quality of life. digital.library.unt.edu/ark:/67531/metadc6127/
Relationship Between Acceptance of Sexual Double Standard Among Male and Female Students and Attitude Toward Sexual Harassment Involving Instructor and Student
The study assessed the relationship between acceptance of sexual double standard and attitude toward sexual harassment among students (N = 426, 141 males and 285 females). A principal components factor analysis with varimax rotation extracted 4 harassment factors: student blame, professor blame, reactions, and feelings about harassment. Controlling for marital status, age, race, and sexual double standard, one-way ANOVA revealed that gender significantly (p=.0001) affected attitude toward sexual harassment. Males reported less sensitivity toward harassment than females. Multiple regression analyses indicated that as acceptance of sexual double standard increases, sensitivity to sexual harassment decreases (p=.001), controlling for marital status, age, race, and gender. Controlling for marital status, age and race, two-way ANOVA revealed an interaction effect between gender and sexual double standard for student blame (p<.0001) and professor blame (p<.0044), where males reported higher levels of blame for both groups under the low sexual double standard condition. digital.library.unt.edu/ark:/67531/metadc5811/
Treadmill validation of the Siconolfi step test.
Access: Use of this item is restricted to the UNT Community.
Maximal oxygen uptake (VO2max) is the internationally recognized measure of a person's cardiorespiratory fitness. Currently the most accurate way of assessing one's true VO2max involves the use of maximal exercise tests, which require the use of specialized equipment, and are time consuming and costly. The purpose of this study was to determine the validity of the submaximal Siconolfi step test to estimate VO2max. A second purpose was to determine if body fat percentage improved the validity. Thirty-six individuals underwent a maximal treadmill test, in which VO2max was directly measured, and the step test. Results indicate that, although VO2max estimates generated by the Siconolfi step test are highly correlated to true VO2max (r =.887; p<.01), the values consistently underestimated a person's aerobic fitness. It was also determined that body fat percentage did not contribute to the prediction of VO2max. digital.library.unt.edu/ark:/67531/metadc5572/
Practices and attitudes toward alternative medicine among college students.
Access: Use of this item is restricted to the UNT Community.
This study assesses practices of college students (N=913) toward alternative medicine, relationships of students' health locus of control with practices of alternative medicine, and relationships of students' attitudes toward alternative medicine and health locus of control. A principal components factor analysis established construct validity of the author-designed Attitude Toward Alternative Medicine Scale, extracting three factors: Holistic Attitude/Control, Safety, and Satisfaction. Holistic Attitude/Control predicted use of alternative medicine (Wald =61.9, p < .01). A principal components factor analysis established construct validity of the Multidimensional Health Locus of Control Scale, extracting three factors: Internal Health Locus of Control, External-Chance, and External-Powerful Others. Internal Health Locus of Control significantly correlated with Holistic Attitude/Control (r = .35, p =.01). digital.library.unt.edu/ark:/67531/metadc5514/
VO2 response profile in heavy intensity cycling after heavy intensity arm or leg exercise.
The elevated CO2 levels, elevated temperature, and lower blood pH that may occur during exercise should enhance O2 delivery to the exercising muscles. It was hypothesized that performance of prior exercise (PE) would result in a faster VO2 response, as well as a reduced slow component contribution, in subsequent exercise bouts. Five women (21 ± 1 yr) and 10 men (23 ± 2 yr) performed nine 6-min bouts of heavy intensity cycle ergometer exercise (i.e., above the ventilatory threshold, individually determined by an incremental test). Three bouts were performed without prior heavy exercise (noPE), three were performed 6 min after a 6-min bout of heavy intensity arm cranking (PEA), and three were performed 6 min after a 6-min bout of heavy intensity cycle ergometer exercise (PEL). Breath-by-breath VO2 data from each of the three sets of three tests were combined and fitted to a two-component model, which ignores the cardiodynamic phase. The primary and slow component amplitudes were truncated to reflect actual increases in VO2 in each phase. The effects of PE on the time constant of the primary component were inconsistent. As hypothesized, the amplitude of the slow component was reduced by PE (noPE vs PEA vs. PEL: 25% > 16% < 14%; p < .05). It is concluded that heavy intensity PE affects characteristics of the VO2 profile in a subsequent bout of heavy intensity leg exercise. digital.library.unt.edu/ark:/67531/metadc5441/
Use of repeated tests and rolling breath averages affects the precision of quantifying the VO2 response profile in moderate intensity cycling.
The purpose of this study was to determine whether working in the field of deaf education, as opposed to general education, results in a higher level of technology integration. A secondary goal was to determine if deaf educators who are deaf integrate technology at a higher level than their hearing counterparts. The instrument chosen for this study was the LoTi Technology Use Profile, a tool used to explore the role of technology in the classroom. A total of 92 participates were included in the study of which 48 were regular educators and 44 were deaf educators. The participants were selected from a population pool whereby teachers were presumably pre-disposed to using technology based upon their attendance at a technology training session in the form of a conference or a class. Deaf educators as a whole did not perform as well as general educators on the LoTi scales. Given the fact that the technology-minded general educators who comprised the sample population of this study scored exceptionally high on the LoTi scales, further research is needed to ensure comparability between the two groups. The findings of the current study do suggest, though, that deaf educators who are deaf have the potential to integrate technology to a greater degree than deaf educators who are hearing. Thus, a primary recommendation is to conduct a national LoTi survey of typical, rather than technology-minded, deaf educators as a comparison to the 2004 national survey of typical general educators. digital.library.unt.edu/ark:/67531/metadc5351/
Body ideals and weight bias: Does ethnicity make a difference?
The current study investigates whether there are there ethnic differences between Caucasian, African American, and Hispanic women in (a) weight bias, (b) body ideals, (c) social awareness and internalization of appearance standards and (d) physical activity in relation to these constructs. Participants included 130 Caucasian, 103 African American, and 52 Hispanic undergraduate female students. Participants completed a demographic survey, the Antifat Attitudes Test, the Figure Rating Scale, the Sociocultural Attitudes toward Appearance Questionnaire, and the Multiethnic Identity Measure questionnaire. No significant ethnic group differences in weight bias emerged. Differences were found for participants' perceptions of the culturally ideal female body shape, as well as awareness and internalization. No relationship was found between physical activity and weight bias, body ideals, and appearance standards. Future researchers should use health weight classifications, in addition to ethnicity, to examine weight bias, body ideals, and physical activity. digital.library.unt.edu/ark:/67531/metadc5360/
Accuracy of Self-Reported Height, Weight, and Calculated BMI and Resulting FITNESSGRAM® Healthy Fitness Zone Classification
Access: Use of this item is restricted to the UNT Community.
The determination of adiposity in adolescents is often assessed with calculations of body mass indices (BMI). Researchers often obtain these measurements from self-reported (SR) values. The purpose of this study was to determine the accuracy of SR height, weight, and calculated BMI (from height and weight). SR and actual measured (ME) BMI values were compared with standards from the FITNESSGRAM® Healthy Fitness Zone (HFZ) classifications. SR height and calculated BMI were found to be accurate while SR weight was, on average, underreported by 4.77 lbs. Because of these errors in SR height and weight, accuracy of classification into the FITNESSGRAM® HFZ was compromised. Consequently, it is important that researchers ascertain actual values of height and weight when measuring adolescents rather than use those from self-reports. digital.library.unt.edu/ark:/67531/metadc5214/
The effects of motivational and instructional self talk on the attentional focus of high school distance runners.
Access: Use of this item is restricted to the UNT Community.
The purposes of this study were to examine the (a) attentional focus strategies used by high school distance runners, (b) changes in attentional focus across four laps in three 1.6 km runs, and (c) effects of a pre-performance intervention using motivational and instructional self talk on the attentional focus strategies used by and performance of high school distance runners. Participants (N = 42) completed a background and demographic questionnaire, the Cross Country Attentional Focus Inventory (CCAFI), a motivational and instructional statement survey, and the Self-Motivation Inventory. A series of oneway ANOVAs revealed significant differences in the types of attentional strategies used by each group, as well as fluctuations in use of strategies. The experimental group associated more during the each of the 1.6 km trials, whereas the control group dissociated more throughout each trial. A significant group by week interaction was found, with the experimental group maintaining their performance and the control group slowing from week one to week three. digital.library.unt.edu/ark:/67531/metadc4738/
Effect of Chronic Alcohol Abuse and Resistance Training on the Skeletal Muscle Androgen Receptor Concentration of Rats
Access: Use of this item is restricted to the UNT Community.
The purpose was to examine the effect of chronic alcohol abuse on the androgen receptor content (AR) in skeletal muscle, and to determine if this effect was influenced by resistance training. Thirty-four male rats (456 ± 1 g; mean ± SE) were divided into 4 groups: Sham exercise-Ethanol, Sham exercise-Normal diet, Exercise-Ethanol, and Exercise-Normal diet. Both Exercise groups underwent a 6-week "squat" resistance training protocol and both Ethanol groups received an alcohol-rich diet throughout the 6-week period. Western blot analysis showed no effect of alcohol or resistance training on the AR of the extensor digitorum longus. For the rectus femoris, alcohol caused a decline in the AR (p=0.01). This reduction was not attenuated by resistance training. The AR of the soleus was not affected by chronic alcohol abuse alone; however, the resistance training induced increase in the AR was prevented by chronic alcohol abuse (p=0.03). digital.library.unt.edu/ark:/67531/metadc4540/
The Relationship of Acculturation Stress and Leisure Satisfaction of Hispanic College Students
Access: Use of this item is restricted to the UNT Community.
Hispanics are the fastest growing minority group in the U.S. and signs indicate a similar trend in their college enrollment. Leisure activities are known to have a moderating effect on individuals experiencing stress in their lives. Hispanic organizations registered with a major 4-year metropolitan university were targeted. The hypothesis for this study was there is no relationship between acculturation stress and leisure satisfaction. Results indicate no relationship between acculturation stress and leisure satisfaction. One explanation for this lack of a significant relationship between these two measures might be that these college students had obtained a high level of acculturation, which would explain the relatively low level of acculturation stress reported. digital.library.unt.edu/ark:/67531/metadc4453/
Exploring flow among Division I and intramural athletes.
This study explores the flow experiences of collegiate athletes. NCAA Division I athletes and intramural athletes (N = 180) completed a series of measures on their flow experiences. Comparisons were made regarding the characteristics of flow, the perceived facilitators of flow, the frequency of flow experiences, and explored the role of perceived ability. Using a person by situation interaction framework, this study singles out perceived ability as a person factor and competitive level as a situational factor to more clearly examine flow experiences. Results indicated distinctions between the two groups. Mainly, the intramural athletes reported experiencing the merging of action and awareness, autotelic experience, transformation of time and having clear goals more frequently than the NCAA Division I athletes. No group differences were found for flow frequency or flow facilitators. Perceived ability was found to have a weak, but significant relationship with specific flow facilitators and characteristics. digital.library.unt.edu/ark:/67531/metadc4494/
Primary Caregiving Father's Perceptions of Leisure
The purpose of this study was to evaluate the impact the primary caregiving role had on men's perceptions of leisure. The Assessment of Leisure and Recreation Involvement (Ragheb, 2002) was used to examine men's leisure. Twenty-five stay-at-home dad groups were solicited via e-mail; 81 men submitted usable responses to an online survey. Respondents considered themselves the primary caregiver for children in the household and at least one child was younger than 12. Descriptive data were collected about the experience of being a primary caregiving father, demographics, and how the caregiving role affects the men's perceptions of leisure. Caregiving fathers in the sample resembled the perceptions of many primary caregiving mothers. Perhaps the "caregiving" role, rather than gender, is a more distinct variable explaining perceptions of leisure by parents. digital.library.unt.edu/ark:/67531/metadc4513/
NCAA division I athletes preferences for coaching behaviors.
The purpose of this study was to determine whether coaching behavior preferences of NCAA Division I athletes differ as a function of gender and type of sport. The Coaching Behavior Questionnare (CBQ; Martin & Barnes, 1999) was administered to 195 NCAA Division I athletes. Gender and sport type were the independent variables and the participant's mean scores for the subscales on the CBQ were the dependent variables. Descriptive statistics revealed that, overall, NCAA Division I athletes prefer positive and instructional behaviors more than non-responses or negative behaviors. A 2 (gender) x 3 (type of sport) MANOVA and follow-up discriminant function analysis indicated that coaching behavior preferences differed as a function of gender and type of sport played. Thus, NCAA Division I coaches should consider both individual and situational characteristics when working with their athletes to achieve the desired outcome. digital.library.unt.edu/ark:/67531/metadc4438/
Attentional focus strategies of multi-sport athletes.
The purpose of this study was to determine (a) the attentional focus strategies used by triathletes during the three stages of an Olympic distance triathlon, (b) if level of experience influences the attentional focus strategies used by triathletes, and (c) whether there is a relationship between athletes finishing times and the attentional strategies used in each stage of the race. Triathletes (N = 160) completed the Triathlon Attentional Focus Inventory, which measured association and dissociation during the swim, bike, and run. One-way ANOVAs revealed significant differences between the athletes' level of experience and the attentional strategies used, as well as differences between the athletes overall race time and the attentional strategies used during each stage of the triathlon. Athletes with more experience associated more during the race, whereas athletes with less experience dissociated more throughout the race. digital.library.unt.edu/ark:/67531/metadc4281/
Coaching behavior preferences of interscholastic athletes.
The purpose of this study was to determine whether coaching behavior preferences of interscholastic athletes differ as a function of gender and type of sport. The Coaching Behavior Questionnaire (CBQ; Martin & Barnes, 1999) was administered to 372 interscholastic athletes. The mean scores of the participants' responses to each subscale on the CBQ were the dependent variables and gender and type of sport were the independent variables. Descriptive statistics revealed that female and male interscholastic athletes who perform on coactive, mixed, and interactive sport teams preferred coaches who engage in supportive and instructional behaviors, as opposed to non-responses or negative responses. A 2 (Gender) X 3 (Type of Sport) MANOVA and discriminant function analyses indicated that gender and the degree of interdependency between group members affects preferred coaching behavior. Thus, coaches should consider situational factors and personal characteristics when working with interscholastic athletes. digital.library.unt.edu/ark:/67531/metadc4200/
ADA Compliance and Accessibility of Aquatic Facilities in the North Texas Area
The purpose of this study was to determine the degree to which existing aquatic facilities in the North Texas metroplex complied with the 1991 Americans with Disabilities Act Accessibility Guidelines (ADAAG) and the proposed Americans with Disabilities Act Accessibility Guidelines: Recreation Facilities (ADAAG supplement). Fifty-two aquatic facilities were evaluated based on: parking lot, ticket counter, gate/entry, restroom, dressing area, drinking fountain, pathway, and pool entry method structural domains. Physical measurements and a few direct observations were recorded on the survey instrument. Surveys were then reviewed and facility scores were tabulated. No facility was found to be 100% compliant with ADAAG and the ADAAG supplement. Aquatic facilities are already struggling to catch up with the 1991 ADAAG, but when the United States Department of Justice approves the proposed ADAAG supplement, aquatic facilities will fall even further behind. digital.library.unt.edu/ark:/67531/metadc3557/
Worker-initiated violence: Prevention strategies in park and recreation departments
Workplace violence infects many organizations. This descriptive study assesses the extent to which Texas park and recreation departments institute policies and procedures for preventing worker-initiated violence. Thirty directors from local park and recreation departments were interviewed by telephone and asked to identify whether their departments used specific prevention strategies to thwart instances of worker-initiated violence. The findings reveal few prevention strategies being used and suggest a need for park and recreation managers to increase their awareness and take a more proactive approach to violence prevention. digital.library.unt.edu/ark:/67531/metadc3338/
The Relationship Among Gender, Gender Role Attitudes, and the Anticipated Commitment to Career, Marriage, Family, and Housework
The relationships between gender, gender role attitudes, and participants' anticipation of future life roles (career, marriage, family, and homecare) were examined. Participants consisted of 297 single college students between the ages of 17-29 years (M = 20). Females reported significantly (p< .01) more egalitarian gender role attitudes than males. Significant results were found for the relationship between gender and anticipated life roles (p< .01) as well as between gender role attitudes and anticipated life roles (career role value, r = .14 and marital role value, r = - .18). The study findings suggest a possible gender conflict for females with more egalitarian gender role attitudes and behavior intentions and their male counterparts. digital.library.unt.edu/ark:/67531/metadc3181/
The Construct Validity of Self-Reported Historical Physical Activity
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was to determine the construct validity of self-reported historical walking, running, and jogging (WRJ) activity. The criterion measure was concurrent performance on a maximal treadmill test. Subjects completed a medical exam and treadmill test between the years 1976 and 1985, and completed a follow-up questionnaire in 1986. Questionnaire included an item that assessed WRJ for each year from 1976 through 1985. Data analysis included Spearman correlations, partial correlations, ANOVA, and ANCOVA. Results indicated self-reported historical WRJ can be assessed with reasonable validity when compared with concurrently measured treadmill performance, and there is no decay in the accuracy of this reporting for up to ten years in the past. digital.library.unt.edu/ark:/67531/metadc3097/
The effects of a college human sexuality course on students' sexual knowledge, attitude, and behavior.
Using an experimental-comparison group design, data were collected at the beginning and end of a semester to assess the effect of a human sexuality course on students' sexual knowledge, sexual attitude, and sexual behaviors. Data analysis by t-tests showed statistical differences between the experimental and comparison group only on sexual knowledge scores ( p < .001), with the experimental group scoring higher. T-tests showed statistical difference between males and females in sexual attitude (p< .001) and sexual behavior (p< .001) with women scoring higher than men in the experimental group, and also when experimental and control groups were combined. Although not statistically significant, women scored higher in sexual knowledge than males. digital.library.unt.edu/ark:/67531/metadc3030/
Perceived Submaximal Leg Extension Forces of Young Adult Males
Access: Use of this item is restricted to the UNT Community.
The purpose was to examine actual force (AF) productions of males for accuracy during leg extensions when given a random desired force (DF) ranging from 10-90% of maximal force (MF). Thirty males ranging from 18 to 30 years of age (M = 21.99 + 3.04), who had no previous experience with the test equipment, went through 9 randomly ordered submaximal efforts followed by a maximal effort. Correlations between AF and DF were high (r > .79) and test-retest was consistent between AF (r = .87) and MF (r = .90). Participants consistently undershot DF on both test and retest from 20-90% and overshot DF only at 10%. Power functions revealed exponents of less than 1, indicating that AF grows slower then DF for both test .70 (.95 CI = .63 - .77) and retest .66 (.95 CI = .60 - .73). The results replicate a prior study by Jackson, Martin, Koziris, Ludtke, and Dishman (2001) that used incremental rather than random increases in DF. digital.library.unt.edu/ark:/67531/metadc2840/
The Effect of Steroid Dose Regimen on the Relationship Between Lower Extremity Muscle Function and Cardiac Function in Post Heart Transplant Patients
Access: Use of this item is restricted to the UNT Community.
Differences in cardiovascular/aerobic function in heart transplant patients might be attributed to the rate of corticosteroid withdrawal and/or to skeletal muscle function. This hypothesis was tested among nine male, cardiac transplant recipients. Prednisone dosage was monitored, and isokinetic strength testing was performed at 4 different time periods throughout the first year post-transplantation. Cardiovascular/aerobic measurements were obtained at the fourth time period. Pre-surgery characteristics were obtained from the patient's medical record. Significant Pearson-product moment correlations were only found between muscle function and aerobic function and between pre-surgery characteristics and cardiovascular/aerobic performance. The results of this study show no evidence that rapid reduction of prednisone dosage enhances aerobic function by benefiting skeletal muscle function. digital.library.unt.edu/ark:/67531/metadc2761/
Factors related to cycling performance
There were two primary goals in this investigation. The first goal was to determine if results from field tests (time-trials and a Conconi incremental test) are related to performance in mass-start long-distance bicycle races. The second goal was to investigate inter-relationships among field test variables. The testing variables measured were critical velocity (CV), Conconi anaerobic threshold (AT) velocity, 4mM AT velocity, fatigue index, peak blood lactate, and anaerobic work capacity. Participants were USCF 30 category 1 through 5 cyclists. Participants performed one 20.75 km and two 10.37 km all-out tests in the field. They also performed an incremental test. The tests were performed at one-week intervals. Results from the field tests were compared to recent mass-start racing performance. Results indicated that Conconi AT velocity was related to performance in a 161-km race. There was also a relationship between 4mM AT velocity and CV and between Conconi AT velocity and 4mM AT velocity. It was concluded that field tests might provide information about performance ability in mass-start long-distance bicycle races. digital.library.unt.edu/ark:/67531/metadc2786/
Assessment and Comparison of the Stress Experienced by International and American Students at the University of North Texas
There were two purposes of the current study: (1) to evaluate if the East Asian Student Stress Inventory could be used to assess the stress experienced by International and American students at the University of North Texas and (2) to determine if the Inventory could discriminate between the two groups on the basis of the stress assessment. A sample of International (n=205) and American (n=216) graduate and undergraduate students completed the inventory. Results indicated that the EASSI could be generalized to a wider spectrum of International students. Using principal component factor analysis with varimax rotation, eight factors were extracted: culture shock, physiological symptoms, family pressure, test anxiety, financial difficulties, attitude toward study, social support and academic self esteem. The inventory clearly discriminated between the two groups on the subscales of culture shock, family pressure and attitude toward study and the International students scored higher on these subscales. digital.library.unt.edu/ark:/67531/metadc2801/
Attitudes and behaviors toward weight, body shape and eating in male and female college students
The purpose of this investigation was to assess the association between body mass index as well as race/ethnicity and established correlates of disordered eating including drive for thinness, body dissatisfaction, bulimia, dietary restraint and social physique anxiety in male and female college students. Difference between actual, desirable and perceived body weight was also assessed. ANOVA suggested that as actual body mass index increased, in general, attitudes and behavior toward weight, body shape and eating increased. A two-tailed t-test suggested that males and females differed significantly with regards to attitudes and behavior toward weight body shape and eating. ANOVA indicated that little to no association existed between race/ethnicity and established correlates of disordered eating. digital.library.unt.edu/ark:/67531/metadc2713/
The Effects of Biofeedback on Task Performance
This experiment attempted to study the effectiveness of biofeedback training on an individual's peak performance while performing a stress-provoking task. In a between subjects design 30 individual college students were divided into 2 groups. One group received auditory biofeedback and relaxation training, and the other group received no training. Both groups met the researcher for 1 hour a week for seven weeks. During each session the participant completed a ten-minute Competition and Coaction (C & C) computer software program (Shea, 1992). The biofeedback equipment recorded the physiological state of each of the participants while he/she performed the C & C task. Both groups' physiological values and C & C scores were compared using the SPSS software. The biofeedback group had statistically lower stress values than the non-biofeedback group (Schwartz, 1995). There was no statistical difference between the 2 groups' C & C scores. The STAI Y-1 and Y-2 anxiety inventories were given to each of the participants at the 1st and 7th session to examine the anxiety differences between the 2 groups. There were no statistical differences between the 2 groups' STAI scores. This study's findings show that individuals can be taught to lower their stress response while performing a computer task. digital.library.unt.edu/ark:/67531/metadc2731/
A retrospective study: The relationship between health care costs, absenteeism and body mass index in a group of municipal employees
This study evaluated the relationship of varying body mass index and average annual health care costs and absenteeism in a group of 524 municipal employees. The 269 employees with health care claims and the 487 employees with attendance records were categorized into five different BMI categories based on self-reported weight and height. Findings from the study suggest that as BMI increases, average annual health care costs and average annual absenteeism increase. However, BMI was only significantly related to absenteeism. The study also found significant relationships between education and health care costs and absenteeism. No significant differences for health care costs or absenteeism were found based on race, age, gender, wellness center membership, or smoking status. digital.library.unt.edu/ark:/67531/metadc2607/
The effect of mode and intensity on VO2 kinetics in the severe intensity domain
The purpose of this study was to evaluate the effect of mode and intensity on VO2 kinetics in the severe intensity domain. Seventeen participants completed 3-7 tests each on a cycle ergometer and treadmill. For each test, Tfatigue, VO2max, Tmean response, VO2GAIN, TVO2max and T@VO2max were determined. Linear regression techniques were used to describe the relationship between TVO2max and Tfatigue . VO2max values were higher in running. The VO2 response profile was faster for running than cycling and faster at higher intensities. The faster VO2 response in running may be associated with larger active muscle mass or differences in muscle activation patterns. The faster response at higher intensities may suggest that VO2 response is driven by O2 demand. digital.library.unt.edu/ark:/67531/metadc2493/
Oxygen Uptake Kinetics in Severe Intensity Exercise
The purpose of this study was to describe mathematically the oxygen uptake kinetics during cycle ergometry, and to examine the effect of intensity on the kinetic responses within the severe domain. Sixteen volunteers performed a series of exercise tests at a range of intensities selected to elicit fatigue in ~3 to 10 min. A simple mono-exponential model effectively described the response across all intensities. There was a positive correlation between the response time and the time to fatigue, demonstrating that the maximal oxygen uptake was achieved faster at higher intensities within the severe domain. Models incorporating two components effectively described the responses only in tests lasting 8 min or more. It was concluded that there is a second, slow component in the oxygen uptake response only at the lower intensities within the severe domain. digital.library.unt.edu/ark:/67531/metadc2539/
Goal Setting Strategies, Locus of Control Beliefs, and Personality Characteristics of NCAA Division IA Swimmers
The purpose of the present study was to examine goal setting strategies, locus of control beliefs and personality characteristics of swimmers (108 males and 111 females) from top twenty 1999 NCAA Division IA programs. Three questionnaires were completed: (a) Goal Setting in Sport Questionnaire (GSISQ: Weinberg, Burton, Yukelson, & Weigand, 1993), (b) the Internal, Powerful Others, Chance Scale (IPC: Levenson, 1973), and (c) the compliance subscale and six conscientiousness subscales from the NEO Personality Inventory-Revised (NEO PI-R: Costa & McCrae, 1985). Descriptive statistics from the GSISQ indicated that most of the swimmers set goals to improve overall performance (51%) and set moderately difficult goals (58%). Results associated with the IPC scale revealed that most of the swimmers attributed their sport performance to internal factors. Results pertaining to the NEO-PI-R indicated that most swimmers were highly conscientious, disciplined, purposeful, and determined. digital.library.unt.edu/ark:/67531/metadc2236/
Parents' motivation in registering their child for gymnastics
This study examined factors that motivate parents to involve their children in organized gymnastics programs. A questionnaire based on McCullagh et al.'s (1993) study of recreational soccer players was used along with open-ended questions. The questionnaire was administered to parents of children who were involved in a private gymnastics club. Descriptive statistics of 156 surveys showed that fitness, skill development, and fun were most frequently cited reasons for parents in their decision to enroll and keep their child in gymnastics programs. Competition was the least important factor. ANOVA showed that competition and team membership factors were more important to the parents of competitive gymnasts than parents of recreational gymnasts. Coaches and youth sport program organizers could use these findings to develop and market youth activity programs. digital.library.unt.edu/ark:/67531/metadc2204/
