Relationship Between Ventilation and Oxygen Uptake at 40% And 85% of Peak Oxygen Uptake in 18-35-Year-Old Women Using the Arm Crank Ergometer

Description: This study investigated whether or not a relationship exists between ventilation and oxygen uptake at 40% and 85% of V02 peak intensity in 30 upper body fit and 30 unfit 18- 35-year-old women. The correlations between ventilation and oxygen uptake at 40% of peak intensity for the fit group (r = -.51) and the unfit group (r = -.48) were modestly negative. At 85% intensity the relationship between ventilation and oxygen uptake in the two groups was -.44 and -.66, respectively. The lower correlations between ventilation and oxygen uptake observed at the 85% level of peak intensity among the unfit group could be due to a lower ventilatory threshold (66% = fit; 49% = unfit), lesser local muscle changes, along with reduced lactate and C02 management; all of which would be improved with training.

The Relationship Between Pace Characteristics of Distance Runs and Criterion Measures of Endurance

Description: The purpose of the study was to examine the relationship between treadmill time, maximal oxygen consumption and pace characteristics of the 1.5 and 3 mile runs and to compare the distances and pace characteristics as predictors of aerobic capacity. Subjects were 70 college aged males, ages 18 to 25, enrolled in jogging and conditioning classes at North Texas State University. Three tests were administered: the 1.5 mile run, the 3 mile run and the Bruce treadmill test. The data were analyzed using correlations and factor analysis. Conclusions of the investigation were (1) the 1.5 and 3 mile runs are valid measures of aerobic capacity, (2) the 3 mile run does not significantly increase the correlation between VO2max and endurance runs and (3) pacing characteristics are evident in the 1.5 and 3 mile runs.

The Interrelationships of Strength, Speed, Power and Anthropometric Measures in College Aged Women

Description: The purpose of the investigation was to determine the interrelationships of strength, speed, power and anthropometric measures in women. Sixty females ranging in ages from 18 to 25 volunteered as subjects. Subjects were measured for strength on the bench press, leg extension and leg curl, power vertical jump, speed--a 40 yard dash, body weight (BW) and fat weight (FW) using a scale and skinfold tests. The correlations for strength and power (.35 to .53), strength and speed (-.37 to -.56) and speed and power (-.45) were significant (p < .01). Partial correlations with (BW) and (FW) held constant were also significant, but were not significantly greater than their zero-order correlations.

The Relative Contribution of Flexibility of the Back and Hamstring Muscles in the Performance of the Sit and Reach Component of the AAHPERD Health Related Fitness Test in Girls Thirteen to Fifteen Years of Age

Description: The purpose of the study was to quantify the relative contribution of low back flexibility and hamstring flexibility in the sit and reach test item of the AAHPERD Health Related Fitness Test in order to examine the validity of the sit and reach test. Subjects were 100 female students, 13 to 15 years of age in physical education classes. Hamstring flexibility was measured using the Leighton flexometer. Spinal mobility was measured using a tape measure. The sit and reach test was performed according to instructions given in the AAHPERD Test Manual. Data were analyzed using correlation, linear regression, and multiple regression. Conclusions of the investigation were (1) hamstring flexibility is moderately related to the sit and reach test, (2) low back flexibility has a very small relationship to the sit and reach test, and (3) the sit and reach test is an inadequate measure of low back and hamstring flexibility.

Event Order in the Biathlon Does Not Have an Effect on Metabolic Response

Description: The purpose of this study was to examine the effects of event order on a cycling(C)/running(R) or R/C biathlon. Eight experienced male biathlete/triathletes with a mean age of 24.9 + 4.6 yr formed the sample of the study. Results show no significant interaction effects on oxygen consumption peak, oxygen consumption during steady-state, ventilation, and heart rate when C/R or R/C are performed at 70% oxygen consumption peak for subsequent R and C respectively. These results seem to indicate that the biathlete/triathlete is efficient in both C and R to the extent that event order does not significantly interact with metabolic response in submaximal cycling and running.

Fatigue Related Changes in the Body Motion and Force Application During the Performance of Consecutive Chin-ups

Description: The purpose of this study was to examine the effects of fatigue on force application and resulting movement patterns during the performance of consecutive chin-ups. Special attention was directed toward relating any fatigue effects to upper limb strength dominance. Twenty male adult subjects each performed one trial. Each trial consisted of consecutive chin-ups. Fatigue caused changes in the movement patterns, duration of movement and force applied through the supporting hands. Throughout the performance greater vertical forces were applied through the dominant upper limb segment with the application of these forces resulting in horizontal displacement of the total body center of gravity toward the dominant hand.

The Relationship of the Sit and Reach Test to Criterion Measures of Hamstring and Back Flexibility in Adult Males and Females

Description: The purpose of this study was to examine the criterion-related validity of the sit and reach test as a measure of hamstring and low back flexibility in adult males and females. Subjects were 52 males and 52 females, 20 to 45 years of age. Hamstring flexibility was measured using a goniometer. Spinal flexibility was measured using a tape measure and an inclinometer. The sit and reach test was performed according to the AAHPERD Health Related Fitness Test Manual. Data were analyzed using correlations and appropriate descriptive statistics. Conclusions of the investigation were: 1) in adult males 20 to 45, the sit and reach test is a valid measure of hamstring flexibility but has questionable validity as a measure of low back flexibility, 2) in adult females 20 to 45, the sit and reach test is a moderately valid measure of hamstring flexibility and is not a valid measure of low back flexibility.

The Relationship Between Cohesion and Performance in Competitive Bowling Teams

Description: The purpose of this present investigation was twofold: to determine the relationship between cohesion and performance for successful and unsuccessful bowling teams and to investigate the internal consistency of items from the Group Environment Questionnaire. Subjects were 148 bowling teams (28 men's, 55 women's, 65 mixed--3-5 members each) from 14 different leagues. Results revealed that task cohesion (ATGT) in early, mid, and late season, as well as social cohesion (ATGS) in late season significantly differentiated between high/low cohesion teams. In addition, successful teams (i.e., league position) exhibited significantly higher levels of both task and composite cohesion. All cohesion scales, with the exception of ATGS in early season, revealed a moderate to high level of internal consistency.

A Field Test of Garland's Cognitive Mediation Theory of Goal Setting

Description: The present study examined Garland's cognitive mediation theory of goal setting in a three-minute basketball shooting task. The effects of different goal conditions were also investigated along with achievement motivation and self-motivation as mediating constructs of performance. Subjects (N=150) were males and females, assigned to one of five goal conditions: "do your best", easy, moderate, hard, and improbable. Results indicated no performance differences between the different goal conditions, with subjects in the "do your best" condition performing as well as subjects in the other goal conditions. Results also yielded partial support for Garland's cognitive mediation theory with task goals influencing performance through its influence on performance expectancy. Furthermore, a negative correlation between achievement motivation and performance was found for females in the improbable goal condition and a positive correlation was found between self-motivation and performance for females in the easy goal condition.

Ground Reaction Forces and Ankle and Knee Moments During Rope Skipping

Description: Ground reaction force (GRF) data collected and synchronized with film data to determine peak GRF and calculate moments about ankle and knee during rope skipping. Two, five minute conditions were analyzed for 10 subjects. Condition 1 was set rate and style. Condition 2 was subjects' own rate and style. Means and standard deviations were reported for peak GRF, ankle and knee moments. One way ANOVAs reported no significant difference between conditions for variables measured. Efficiency and nature of well phased impacts during rope skipping may be determined by combination of GRF, similarities in magnitude and direction of joint moments, and sequencing of segmental movements. Technique and even distribution of force across articulations appear more important than magnitudes of force produced by given styles.

A Kinematic Comparison Between Greater-and Lesser-Skilled Powerlifters Doing the Traditional Style Deadlift

Description: Comparison kinematic models of the traditional style deadlift are presented. Data was obtained through film and analyzed via computer and computer graphics. The comparison between the models revealed that the greater-skilled: 1. used less trunk flexion from the instant of initial trunk lean to the instant of maximum trunk lean, 2. used less knee extension (in same time interval as 1), and 3. demonstrated a smaller horizontal distance between the body center of mass (CM) and the CM of the bar at the instant the bar left the platform. A trend was also observed in which the greater-skilled subjects demonstrated less thoracic lean than the lesser-skilled group at the time the bar reached knee level.

Three Dimensional Comparison of Free Throw Shooting: the Women's Small Ball vs. the Large Ball

Description: The purposes of this study were to quantify, in three dimensions (3D), kinematic parameters of the free throw shot with both the women's small ball and the large ball, and to compare the parameters of the small ball to the large ball. Nine female varsity college basketball players were filmed and the 3D data were computed with the Nonlinear Transformation method. Statistical analysis of parameters including ball trajectory and body position failed to show an effect for ball condition. Since the velocity of release was not statistically different between the two balls and the ball mass was different, the results suggest that impulse is the differing factor.

Comparison of the Personalities of Non-Injured and Injured Female Athletes in Intercollegiate Competition

Description: This study was designed to determine if differences exist between the personalities of injured and non-injured athletes, injured and non-injured athletes in individual sports, and injured and non-injured athletes in team sports. Subjects were forty-three female athletes selected from six intercollegiate teams. The test instrument was the Cattell Sixteen Personality Factor Questionnaire. Data were analyzed by the two-way analysis of variance. Alpha was .05. Conclusions of the investigation were that the personality of injured athletes does not differ from the personality of non-injured athletes, that non-injured athletes in individual sports are more self-assured than non-injured athletes in team sports, and that the personality of athletes in team sports does not differ from the personality of athletes in individual sports.

The Effect of Hypoxic Training Upon the Speed of Sprint Freestyle in High School Competitive Swimming

Description: This study investigated possible effects of hypoxic training upon speed of high school sprint freestyle. Thirty-eight subjects, grouped as their two schools, performed identical loads during the ten-week program. The Experimental group used hypoxic techniques for about one-half of each workout. Pretests and posttests conducted for the 50-yard and 100-yard distances yielded highly correlated mean scores, with marked differences between the two groups. Analysis of covariance was used, selecting the .05 level for rejection. The comparison of adjusted group means indicated neither group superior at 50 yards, while the 100-yard F-ratio was significant at the .0047 level favoring hypoxic training. It is recommended that hypoxic techniques be incorporated into existing programs, possibly benefitting other strokes.

The Relationship of Self Concept to Participation in Extra-Curricular Activity Among Fourth Grade Children

Description: This study attempted to determine the relationship between self concept and participation in extra-curricular activity: specifically, whether self concept differentiates between participants and nonparticipants and whether self concept scores differed between male and female participants. Sixty fourth graders were assessed on self concept by the Piers-Harris Children's Self Concept Scale. Participation or non-participation was determined by written parental response. Analysis of variance was used, with level of significance at .05. There was no evidence that participants can be distinguished from non-participants on measures of self concept. Scores on self concept did not differ for males and females.

The Relationship of Anxiety to Performance in Stressful Situations in Slo-Pitch Softball

Description: The purposes of the study were to compare (1) the relationship between competitive A-trait and competitive A-state in Slo-Pitch softball and (2) the relationship between A-trait and performance in selected stressful situations in softball. The study also considered the ranking of players by a manager and overall performance. The Sport Competition Anxiety Test and a competitive short form of the State Anxiety Inventory were used to measure A-trait and A-state. Trait anxiety, state anxiety and performance were compared using the Pearson product moment correlation technique. Trait anxiety scores were found to be accurate predictors of pregame state anxiety, but not of performance. The manager's rating was a better predictor of performance than competitive A-trait in selected stress situations.

The Influence of Psychological Stress and Personality upon Athletic Performance of Intercollegiate Tennis Players

Description: This investigation was designed to study coach and self-appraised groupings of intercollegiate tennis players who yield to stress and withstand stress and to determine if personality differences existed between groups. Subjects were 75 intercollegiate tennis players from Texas. A stress inventory and the Cattell Sixteen Personality Factor Questionnaire were instruments utilized in the study. Data were subjected to hierarchical profile-groupings, three-way analyses of variance, and a correlational analysis. Conclusions of the study were that intercollegiate tennis players and male and female players respond to stress differently; intercollegiate tennis players and male and female players who experience different levels of stress have different personalities; and players and coaches do not evaluate the ability to cope with stress similarly.

A Kinematic Analysis of the Baseball Batting Swings Involved in Opposite-Field and Same-Field Hitting

Description: The purpose of the study was to examine selected mechanical factors involved in hitting a baseball to the same and opposite fields. Special emphasis was placed on an identification of those factors which distinguish players of different hitting abilities. Twenty male college level baseball players, ten in each of two groups, hit six pitched baseballs, three each to two assigned areas of the playing field. The movement patterns for the opposite field and same field batting swings appeared to be similar in form with differences between the two swings due to (a) differences in the angular displacements at the left wrist and left elbow joints and (b) differences in the temporal characteristics.

Initial Starting Posture and Total Body Movement-Reaction Time for Lateral Movement

Description: Eighteen subjects each performed fifty-five trials which consisted of assuming an initial stance and then in response to a visual stimulus running to either the left or right. For each trial both the foot width spacing and orientation of the feet were varied. Direct and indirect measurements were taken of selected temporal and kinematic parameters. The conclusions were that no interactions or differences exist among foot width spacing, foot orientation, and direction of movement; the jab step start is the preferred initial movement; the preferred foot width spacing is 46.6 centimeters; the preferred angular orientation of both feet is approximately 1.36 radians.

The Effects of Mastery, Competitive and Cooperative Goals on Performance in Simple and Complex Sport Skills

Description: The present study investigated the effects of different goal and feedback conditions on performance of a basketball field goal shooting task and a more complex one-on-one offensive basketball task. Subjects (N = 100) were matched, based on pre-test performance, into one of five conditions: competitive goal, cooperative goal, mastery goal, "do your best" with feedback, and "do your best" without feedback. Results indicated the competitive group was significantly better than the "do your best" without feedback group in one-on-one performance. No other between group differences were significant, although some consistent group trends were present. Subjects' goal orientations were not related to performance in specific goal conditions, with the exception of mastery oriented subjects in the mastery goal condition.
