| Outline of Final Research Achievements |
This study aimed 1) to develop optimal conditions of high-intensity interval training (HIT) by determining metabolic profile during various intermittent exercise under normoxic and hypoxic conditions, and 2) to confirm the effects of selected HIT performed under the hypoxic conditions on metabolic capacity and intense exercise performance. The results indicated that during short lasting high-intensity intermittent exercise, peak and accumulated oxygen uptake were the greater in a normoxic condition, alternatively oxygen deficit became greater under moderate hypoxic conditions. In experiment 2, HIT under hypoxic conditions corresponding to 4000m above sea level was done, the greater improvement in maximal accumulated oxygen deficit, maximal anaerobic power, and consequently sprint swimming performance were observed.
