Outline of Final Research Achievements |
To improve exercise performance, individuals often engage in short-term high-intensity exercises. However, there is a risk of decreased blood pressure and potential syncope following exercise. It has been reported that voluntary hyperventilation or hypoxia can further enhance anaerobic metabolism during high-intensity exercise, while also leading to a greater decline in blood pressure after exercise. This study aimed to examine the combined effects of hyperventilation and hypoxia on physiological responses during and after high-intensity exercise. Our findings suggest that voluntary hyperventilation and hypoxia synergistically decrease aerobic metabolism and increase anaerobic metabolism during high-intensity exercise. However, these factors do not significantly impact the extent of post-exercise blood pressure reduction.

Academic Significance and Societal Importance of the Research Achievements |
本研究成果から、低酸素吸入と自発的過換気の組み合わせは、単独の介入と比較して運動後の血圧低下の程度を大きくすることなく、高強度運動時の無酸素性代謝をさらに亢進させることが示唆された。これは、高強度運動のパフォーマンスを向上させるトレーニングとして安全で、これまでよりも効果的に無酸素性代謝を亢進することができる方法であると考えられる。そのため、本研究成果は安全かつ効果的な新たなトレーニング法の開発に寄与したと考えられる。
