Maximal oxygen intake and associated physiological variables were measured during strenuous exercise on women subjects

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 essentially 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 ml./kg./min. and mean maximal heart rate was 185.8 bts./min. In the endurance performance test the mean run time for all subjects was 4:35.8 minutes. Correlation between maximal oxygen intake and performance time was calculated and found to be insignificant (r = .066); however, a highly significant correlation was obtained between maximal oxygen intake and physical work done during the performance test (r = .64).
