Outline of Final Research Achievements

In this study, we determined the effects of mild hyperbaric oxygen (1.3 atm, 30-38% oxygen environment) on various physical stresses and muscle damage that occur after high-intensity exercise in humans and animals. Exposure to mild hyperbaric oxygen did not increase oxidative stress after 1 hour of high-intensity exercise. Furthermore, mild hyperbaric oxygen quickly recovered the muscle injury in the tibialis anterior muscle treated with cardiotoxin, which cause muscle injury.

Academic Significance and Societal Importance of the Research Achievements

トレーニング実施後の効果的な回復は、高頻度のトレーニング実施や、アスリートが連日の試合を行う際のパフォーマンス向上に貢献する。軽度な高気圧酸素 (1.3気圧、30%から38%酸素環境) への滞在は酸化ストレスの増大を引き起こさずに、筋損傷を早期に回復させることが明らかになった。そのことから、軽度な高気圧酸素環境は特にアスリートや運動愛好家などの高強度運動後の一時的な運動機能の低下を早期に回復させる可能性が示された。
