| Outline of Final Research Achievements |
The purpose of this study was to investigate the physiological adaptations of two typical types of respiratory muscle training, and to identify the more suitable training method for long-distance athletics events in track and field based on athletic performance and physiological parameters.
The individual times for the 5000m run improved in long-distance runners who underwent respiratory muscle endurance training (RMET) by voluntary isocapnic hyperpnea than those who underwent inspiratory muscle strength training by pressure threshold loading in inspiration. Additionally, respiratory muscle oxygenation levels improved in the RMET group.
These results suggest that respiratory muscle endurance training, which promotes faster and deep breathing than high loading during inspiration, improves respiratory muscle oxygenation levels and may be effective for improving performance in long-distance events in track and field.

| Academic Significance and Societal Importance of the Research Achievements |
競技パフォーマンスの向上効果に対して見解が未だ乏しい呼吸筋トレーニングに着目し，代表的な2種類の呼吸筋トレーニングにおける生理的適応を明らかにしたことは，呼吸筋トレーニングによる効果を生理学的に解明することに貢献できたと考える．
さらに，陸上競技の長距離走種目に適した呼吸筋トレーニング法を明らかにしたことは，長距離ランナーが呼吸筋トレーニングを科学的根拠に基づいて選択する際の指針となり，競技記録の更新へ導く可能性がある点で社会的意義があると考える．
