| Outline of Final Research Achievements |
This study aimed 1) to develop optimal high-intensity interval training (HIT) under hypoxic conditions for improving sprint performance of elite swimmers, and 2) to confirm the effect of HIT under the hypoxic conditions. The results indicated that during both high-intensity continuous and intermittent exercise lasting ~1 minute, accumulated oxygen uptake was the largest in a normoxic condition, alternatively oxygen deficit became greater with decreasing oxygen partial pressure. In experiment 2, HIT under hypoxic conditions corresponding to 4000m above sea level was done, the greater improvement of sprint swimming performance associated with greater increases in maximal oxygen deficit and maximal propulsive power were observed, which suggests a beneficial effect of HIT under moderate hypoxic conditions.
