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 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.
