The purposes of the study were to determine (1) the effect which exercise of the nondominant arm would have upon the reaction-movement time of the dominant and nondominant arms, (2) the degree to which fatigue transfers from one arm to the other arm, and (3) the influence of lateral dominance upon the reaction-movement time of both the dominant, and nondominant arms.

This study used cinematography to determine differences in velocity, acceleration, moments of force, and body centers of gravity in four different positions of two techniques of the long-hang kip. Three female gymnasts performed five attempts of each technique: the traditional method, with an arch in the lower back at the end of the forward swing, and approximate shoulder angle of 180 degrees or more; and the newer method, with no arch in the lower back and approximate shoulder angle of 90 degrees or less. Three. USGF-rated judges scored the kips, and due to inability to distinguish between the two techniques, two subjects were eliminated. Major differences occurred in the swing extension, with the newer technique producing more velocity and a higher center of gravity throughout the movement.

The purpose of this study was to investigate strength and flexibility development as each is affected by three training programs using two apparatuss the Exer-Genie and the Super-Mini-Gym.

The purpose of the investigation was to determine the effect of the tonic neck posture upon fatigue induced by exhaustive exercise of the knee extensor muscles of college women. The subjects were college females enrolled in physical education activity classes at North Texas State University. The F ratio was used to determine significance of the difference in fatigue measures in the three head positions. The results of the present investigation revealed no statistically significant difference between the three head positions with respect to their influence on endurance of the leg extensors. Conclusions were that the tonic neck reflex does not facilitate or inhibit leg extensor endurance.

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.
