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.

This study analyzed an individual's ability to perceive levels of exertion of an isometric contraction. Two samples of college students were tested under magnitude production or magnitude estimation. A significant F was obtained for the magnitude production condition. An insignificant F was obtained for the magnitude estimation condition. This study concludes that subjects tested under magnitude production will perceive the 100 percent level with the least amount of error and that error will increase as the percentages descend from the 100 percent level. Subjects tested under magnitude estimation will be equally in error when perceiving percentages of a maximum contraction of the forearm flexors.

The purpose of this study was to examine selected mechanical factors involved in the tennis serve. Special emphasis was placed on identifying factors which distinguish players of different serving abilities. Ten right-handed female tennis players, five ranked, and five unranked, were evaluated, following filming with a high-speed camera, on the basis of five good and five fault serves. The ranked players were seen to differ from the unranked players with respect to (a) serving consistency, (b) initial Y-center of gravity values, (c) certain segment angles at the peak of the ball toss and at ball contact, and (d) certain joint angles at the moment of the ball contact.

"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.

This investigation is concerned with the problem of determining whether or not a significant difference exists between attitudes of junior high school female athletes and non-athletes toward physical education.

The purposes of this study were (1) to determine if three selected aerobic dance related conditions would result in chronic alterations of flexibility of college women and (2) to compare flexibility measures of college age females during a semester of aerobic dance instruction. Subjects were sixty-three college women enrolled in aerobic dance, bowling, and archery classes. Eight flexibility measures were obtained during the third and eleventh weeks of the experimental period. Data were analyzed by a factor analysis the Pearson Product Moment Correlation, and eight oneway analyses of covariance. Conclusions of the investigation were (1) a program of aerobic dance alone is not sufficient to promote flexibility, and (2) supplemental flexibility activities of ten minutes duration used with aerobic dance training are beneficial in increasing hip flexion.

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.

This investigation was undertaken to compare the degree of job satisfaction of physical education faculty who were employed at community/junior colleges and four-year universities. The relationship of selected demographic variables (sex, age, contract longevity, teaching experience, and highest degree completed) to faculty job satisfaction was also investigated. Faculty (N = 70) who were employed in community/junior colleges and universities in the Dallas-Fort Worth area were chosen as subjects for the study. Two instruments were utilized to collect the data. These were the Personal Data Inventory (PDI) and the Purdue Teacher Opinionaire (PTO). Analysis of the data indicated that university faculty and community/junior college faculty differed significantly in their perceptions of job satisfaction in the specific areas of teacher rapport with immediate supervisor, curriculum issues, and school facilities and services. Four demographic variables (sex, age, contract longevity, and teaching experience) were significantly related to ten specific areas of job satisfaction and to the subjects' total job satisfaction.

"The purpose of the study is two-fold: (1) to compare the 1939-40 living conditions that prevailed in the men's college dormitory with living conditions that existed in sixteen college-supervised residences for men; (2) to compare the living conditions that existed in 1939-40 in both the men's dormitory and the college-supervised residences for men with standards set up by authorities in the field of college student housing."--1.

The purposes of the study were to compare ratings of perceived exertion of aerobic dance and treadmill performances under equal work loads and to compare ratings of perceived exertion by males and females in aerobic dance and treadmill work. Subjects were twenty-six college men and women in co-educational conditioning classes. Heart rates were monitored after work bouts and perceived exertion was determined using Borg's RPE scale. Data were analyzed by a two-way analysis of variance with repeated measures. Conclusions of the investigation were: (1) aerobic dance is perceived as less strenuous than the treadmill under equal work loads, and (2) males and females perceive aerobic dance as less strenuous than the treadmill under equal energy bouts.

The purpose of this study was to investigate two different plyometric training techniques for increasing vertical jumping ability. Twenty-four female high school volleyball players were matched for height and weight and distributed equally among three groups. Each subject performed a vertical jump test, Margaria power test, Wingate bicycle test, and an isokinetic leg strength test prior to and following six weeks of training. Plyometric training significantly (p<.05) improved vertical jumping ability and some indices of leg strength and power. Weighted plyometrics did not enhance performance more than plyometrics alone. These data support the view that plyometric training with or without added weights enhances vertical jumping and leg power.
