Abstract

This study consists of two training experiments using a mechanically braked cycle ergometer. First, the effect of 6 wk of moderate- intensity endurance training (intensity: 70% of maximal oxygen uptake (V̇(2max)), 60 min·d-1, 5 d·wk-1) on the anaerobic capacity (the maximal accumulated oxygen deficit) and V̇O(2max) was evaluated. After the training, the anaerobic capacity did not increase significantly (P > 0.10), while V̇O(2max) increased from 53 ± 5 ml·kg-1·min-1 to 58 ± 3 ml·kg- 1·min-1 (P < 0.01) (mean ± SD). Second, to quantify the effect of high intensity intermittent training on energy release, seven subjects performed an intermittent training exercise 5 d·wk-1 for 6 wk. The exhaustive intermittent training consisted of seven to eight sets of 20-s exercise at an intensity of about 170% of V̇O(2max) with a 10-s rest between each bout. After the training period, V̇O(2max) in- creased by 7 ml·kg-1·min-1, while the anaerobic capacity increased by 28%. In conclusion, this study showed that moderate-intensity aerobic training thai improves the maximal aerobic power does not change anaerobic capacity and that adequate high- intensity intermittent training may improve both anaerobic and aerobic energy supplying systems significantly, probably through imposing intensive stimuli on both systems.
