Outline of Final Research Achievements

The present study attempted to investigate the effects of high intensity and low frequency interval training on exercise performance-related cardiovascular functions.
Study 1: High intensity and low frequency interval training induced significant increases in maximal oxygen consumption, oxygen consumption at respiratory compensation point, left ventricular mass in student soccer players. Study 2: The training induced a more rapid heart rate recovery after exercise in childhood. Study 3: The training method also increased maximal oxygen consumption, and improved the augmented response of head-up tilt induced diastolic blood pressure in college volleyball players.

Academic Significance and Societal Importance of the Research Achievements

我々は週に1回の高強度インターバルトレーニングが,呼吸循環機能の向上に効果的であることをすでに明らかにしている。本研究において,幼児期からアスリートに至るまで幅広い対象者に,革新的なインターバルトレーニングの効果を明らかにし,汎用性が高くなったことは,学術的・社会的に価値が高い。また,一般的に呼吸循環系の機能改善には,週に3~5のトレーニング頻度を有するため,本トレーニング手法が広まることで,技術・戦術面を高める時間の確保が容易となり,意義は高いと考える。
