Abstract
Maximal O2 uptake (.ovrhdot.VO2 max) and percent body fat (%BF) were assessed in 87 males and 57 females before and after 7 wk of Army basic training. .ovrhdot.VO2 max was determined, using a running treadmill protocol and %BF was measured by skinfold technique. .ovrhdot.VO2 max increased 3.7% (50.7 vs. 52.3 ml/kg.cntdot.min) and 10.5% (36.9 vs. 39.3 ml/kg.cntdot.min) for males and females, respectively, with training. %BF decreased 11% in males and 7.1% in females while body weight increased in both. Analysis of variance revealed that, while these changes were significant, there was no quantitative difference in the response of the sexes undergoing the same training program. Basic training presents an effective physical challenge for those males and females who have a .ovrhdot.VO2 max below the ranges of 49.52 ml/kg.cntdot.min and 38-41 ml/kg.cntdot.min, respectively, upon entry. It effectively reduces BF content of those who initially possess high percentages and increases the lean body mass, particularly in women.
