The Significance of Time to Exhaustion at the Velocity at VO2Max

Description: 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)].

Do American Adults Know How to Exercise for a Health Benefit?

Description: 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 fro… more

Reliability of an On-line System to Assess Physical Activity Behaviors in an Active Group of Kinesiology Undergraduate Students

Description: Engaging in muscle strengthening activities (MSA) as part of a physical activity program offers health benefits. Although the merits of physical activity are well documented, many adults fail to meet appropriate levels as recommended in the 2008 Physical Activity Guidelines for Americans (PAGA). To get a more complete understanding on an individual's physical activity behaviors, the Tracking Resistance Exercise and Strength Training (TREST) internet based survey was developed. The purpose of th… more

Physiological and Psychological Effects of an Acute Stressor: Comparing Coping Strategies Among Very Physically Active and Less Active Adults

Description: The purpose of this study was to examine whether physical activity status of healthy adult males (N = 59) while in a coping strategy condition (association, disassociation, or control) influences psychophysiological responses to an acute painful stimulus. Measures of pain tolerance, state anxiety, body awareness, and salivary cortisol were investigated. Results indicated no significant differences between physical activity groups for pain tolerance, stress responses (i.e., self-reported state a… more

The Effect of Season Performance on Male and Female Track and Field Athletes’ Self-identity

Description: Although the “self” has generally been conceptualized as relatively stable in sport-specific research, events such as deselection, injury, and career termination have been found to negatively affect athletes’ levels of identification with the athlete role. Additionally, there has been limited research regarding competitive failure and its ability to negatively affect athletes’ levels of identification with the athlete role. The purpose of the present investigation was to provide additional evid… more

Factors Related to Meeting Physical Activity Guidelines in College Students: a Social Cognitive Perspective

Description: Engaging in regular physical activity is important for maintaining and improving health. Unfortunately, most college students fail to meet the recommendations for both aerobic and muscle-strengthening physical activity guidelines (PAGs). Psychosocial factors described within the social cognitive theory are related to the acquisition and retention of physical activity behaviors. The purpose of this study was to examine the relations of gender, self-efficacy, outcome expectancies, and social supp… more

The Effects of Mental Imagery Training on a Baseball Throwing Task

Description: This study was designed to determine if long term training of mental imagery skills is more beneficial to an athlete than immediate imagery rehearsal practiced only prior to an event. Subjects were thirty male high school baseball athletes who were randomly assigned to one of three treatment conditions: (1) long term imagery training and practice; (2) immediate imagery practice only; and (3) control. An accuracy relay-throwing test was performed with pre-test, mid-test, and post-test performanc… more

Predicting Peak Oxygen Uptake from Ratings of Perceived Exertion During Submaximal Cycle Ergometry

Description: The purpose of this study was to predict VO2pak using ratings of perceived exertion (RPE), heart rate (HR), and percent fat (PFAT). Subjects were males (n= 60) (PFAT, M SD = 14.4 6.1) and females (n= 67) (PFAT, M SD = 23.4 4.9) with ages ranging from 18 to 33 years. Subjects performed an incremental cycle ergometer protocol and RPE, HR and Vo2 were measured at each stage until VO2 ak was achieved. Mean RPE and HR at the submaximal workload of 100 watts were, (RPE100) M= 12.7 2.6 and (HR100) M= … more

The Effects of a Psychosocial Environment on College Women’s Exercise Regulations and Social Physique Anxiety

Description: A positive psychosocial intervention comprised of high autonomy support, task-involvement, and caring was implemented in physical activity classes to examine its effects on college women’s basic psychological needs (i.e. autonomy, competence, relatedness), exercise regulations (i.e. external, introjected, identified, integrated, intrinsic) and social physique anxiety (SPA). We hypothesized that at the end of the semester, participants in the intervention group (N = 73) would report greater need… more

Evaluating the Pulse Sensor as a Low-Cost and Portable Measurement of Blood Pulse Waveform

Description: This study was aimed at determining whether the digital volume pulse waveform using the Pulse Sensor can be used to extract features related to arterial compliance. The Pulse Sensor, a low-cost photoplethysmograph, measures green light reflection in the finger and generates output, which is indicative of blood flow and can be read by the low-cost Arduino UNO™. The Pulse Sensor code was modified to increase the sampling frequency and to capture the data in a file, which is subsequently used for … more

Does Downhill Running Alter Monocyte Susceptibility to Apoptosis?

Description: Introduction/purpose: Recovery from muscle damage involves a type of programmed cell death known as apoptosis. Damage Associated Molecular Patterns (DAMPs) are released after muscle damage and may cause premature apoptosis in monocytes infiltrating the damaged site. This may alter the time course of events towards recovery. Therefore, the purpose of this study was to investigate if downhill running causes a change in the susceptibility of monocytes to apoptosis. Methods: Participants (5 male, 6… more

Academic Stress in Student-Athletes

Description: Academic stress and the causes of such stress are subjects that are found in very few studies concerning student-athletes. Therefore, the purpose of this quantitative study is to determine how the following variables relate to academic stress and perceived stress either through correlations or differences--demographics, academic classification, major or field of study, athletic scholarship status, and season of sport (in- season/ out of season). An online questionnaire containing a Perceived St… more

Music With and Without Lyrics Increases Motivation, Affect, and Arousal during Moderate-Intensity Cycling

Description: Music is used to distract, energize, and entertain during exercise by producing positive psychological and physiological responses. Specifically, listening to music during exercise enhances performance, increases motivation, improves affect, and optimizes arousal. Researchers have identified several elements of music that may moderate this relationship, including lyrics. However, few studies to date have examined the influence of motivational lyrics on psychological and physiological states dur… more
