| Outline of Final Research Achievements |
This study aimed to clarify the sex-based differences in exercise performance improvement under high altitude hypoxic training.
It was suggested that staying perform exercise training in a high-altitude environment contributes to performance improvements in men and women. However, respiratory and circulatory adaptations during high-altitude exercise training followed different adaptations for men and women. It was suggested that the mismatch between ventilation and blood flow may increase the process of ventilation adaptation for high-altitude boys. In addition, in women, prominent improvement in glucose metabolism occurred during exercise. The difference was also seen between men and women in the high-altitude hematopoietic process, suggesting that quantitative improvement may take longer in women.

| Academic Significance and Societal Importance of the Research Achievements |
高地・低酸素トレーニングによりもたらされた効果のリスクに目が向けられることは思いの外少ない。正に高地・低酸素トレーニングの健康・安全管理における盲点といっても過言ではない。本研究では性差を考慮した新たなエビデンスによる高地・低酸素トレーニング構築の為の、系統的な基礎資料を得ることに成功した。“成功率は半々”といわれている高地・低酸素トレーニングの成功率を高めるだけではなく、健康・安全対策の盲点を埋める取り組みと言える。
