초록

This study was designed to determine changes in oxygenation of skeletal muscle following intermittent anaerobic training in hypobaric hypoxia. The subjects of study were consisted of each 22 male college students. The subjects were randomly assigned to either a sea-level(n=12) or a hypobaric hypoxia(n=10) traning group. Two groups of subjects trained 3 times a week for a total of 4 wk on a treadmill. Main results of the present study were as follows: 1) body weight and body fat were significantly (p<.05) decreased in hypobaric hypoxia group. and lean body mass were tend to decrease in both two groups. 2) reticulocyte and RBC, oxygen-carrying capacity, were increased in group of sea-level, decreased in group of hypobaric hypoxia, but Hb was increased in both of two groups, Hct was slightly increased in sea-level group only. 3) Hct was slightly increased in group of sea-level group only. 4) Of several data obtained from oxygenated skeletal muscle, △HHb was significantly (p<.05) decreased at 10th minute of exercise in sea-level group and was significantly (p<.05) decreased during exercise From 10-20 minutes of exercise in hypobaric hypoxia group. TOI was significantly (p<.05) increased during exercise in both group. It was concluded that the anaerobic training would have positive effects on body composition and oxygen utilization capacity in skeletal muscle.
