Abstract
Maximal oxygen intake and other associated physiological variables were measured during strenuous exercise on fairly active women subjects (N = 20, physical education majors). The method described by Taylor et al. (14) was used. Following assessment of maximal oxygen intake, all subjects underwent an all-out performance test at the work level which had elicited her maximal oxygen intake. Mean maximal oxygen intake was 41.32 mi/kg/min and mean maximal heart rate was 185.8 bpm. In the endurance performance test the mean run time for all subjects was 4:35.8 min. Correlation between maximal oxygen intake and performance time was calculated and found to be insignificant (r = .07); however, a highly significant correlation was obtained between maximal oxygen intake and physical work done during the performance test (r = .64).
