Abstract
Tested at the beginning and the end of the 6 wk training program which all incoming cadets (plebes) undergo upon entering the U.S. Military Academy were 29 males and 26 females (17-21 yr old). The aerobic training consisted of running for 30 min 5-6 day/wk at varied speeds depending upon performance in an initial 1.5 mile run test. Females responded to training with a significant increase (P < 0.001) in .ovrhdot.VO2 max [O2 ventilatory rate] from 46.0 .+-. 1.0 to 49.7 .+-. 0.8 ml/kg .cntdot. min (7.9%). Males did not increase their initial .ovrhdot.VO2 max (59.4 .+-. 1.1 ml/kg .cntdot. min) significantly. Both groups significantly reduced HRmax [maximum heart rate] and percent body fat. Their initial .ovrhdot.VO2 max values and activity history accounted for the lack of a significant increase in this highly-fit population of males. Blood lactates were significantly decreased (P < 0.05) at the same 2 submaximal workloads after training. The initial difference in aerobic power between males and remales was reduced from 22% to 18%.
