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.

Acute effects of repeated sprinting upon serum creatine kinase (CK), lactic dehydrogenase (LDH), and isozymal activities were studied in five collegiate runners (R_s) and six non-runners (NR_s ). After an intermittent running treadmill test, blood sampling showed three-fold mean increases in CK with no change in LDH in both groups; group differences were insignificant (p>.05). Results suggest (1) intense anaerobic exercise produces moderate enzyme elevations; (2) relatively equivalent exercise intensities are critical to enzyme responses in exercising individuals of varying fitness levels; and (3) exercise-induced enzyme release may be consequential to muscle cell membrane permeability changes from decreased intracellular high-energy phosphates.

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.

The study conducted consisted of an interview with forty-eight varsity baseball coaches of the University Interscholastic League high schools within the Dallas-Fort Worth metroplex. Overall the coaches were found to be a highly qualified group of physical educators. Findings of the study included data on the playing experience, coaching experience, and educational backgrounds of the coaches. Physical education/ coaching areas investigated included: 1) medical-legal, 2) sociological and psychological, 3) kinesiological, 4) physiological, and 5) theory and techniques of coaching. Recommendations included continued professional involvement of coaches, further studies on professional preparation, a course in legal liability, and implementation of a "coaching endorsement".

The purpose of this study was to determine to what extent the existing Recreation Program of Denton, Texas provides for the leisure time needs of the citizens of Denton. After the existing program was surveyed, the results were compared with the standards set up by the National Recreation Association for a city the size of Denton. From a comparison of the present program and the standards, an effort was made to formulate a program that would meet the leisure time needs of the citizenship of Denton.

"The purpose of this study was to determine the percent of boys who had hobbies; what influenced their choice of hobbies; what types of hobbies were selected; what were their recreational, educational, and vocational values; and what were their environmental influences...One hundred and ninety-eight questionnaires were filed out in the schools that were in the high economic districts, one hundred ninety-one in the medium districts, and one hundred ninety-seven in the low districts. This made a total of five hundred and sixty-five questionnaires used in the analysis... Comparisons and analyses of all the groups were made by means of numbers, percentages, and averages.
