| Research Abstract |
We investigated the effects of hypoxic exercise training on muscle energy metabolism. First, we examined the difference in metabolic kinetics during short-lasting, high-intensity constant-load exercise under conditions of normoxia and hypoxia. We found that the aerobic energy release was smaller and compensatory anaerobic energy release was larger under hypoxia than under normoxia, during exercise at the same absolute load. Next, we examined the effects of short-lasting, high-intensity exercise training under hypoxia on muscle energy metabolism. The results indicated that muscle anaerobic capacity is more effectively improved under hypoxia than under normoxia by short-lasting, high-intensity exercise training.
