| Outline of Final Research Achievements |
In order to examine new possibilities of altitude (hypoxic) training, present study aimed 1) to clarify metabolic profiles during various high-intensity (sprint) continuous and intermittent exercises under normoxic and hypoxic conditions, and 2) to confirm the effects of selected sprint interval training (SIT) 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 normoxic condition, alternatively oxygen deficit became greater under moderate hypoxic conditions. SIT used in this study improved significantly maximal accumulated oxygen deficit, maximal anaerobic power, and consequently high-intensity exercise performance. Furthermore, it is demonstrated that the amount of improvements for these variables are greater when SIT is done under hypoxic conditions, rather than performed under normoxic condition.
