業績等

研究領域	パフォーマンスを最大化するトレーニング・コンディショニング研究
研究紹介	私たちが最高のパフォーマンスを発揮するためには、身心の健康を整え、最適なトレーニングを行う必要があります。そのトレーニングは、みなが同じものでいいというわけではなく、身心の疲労状態、ストレス状態を評価し、科学的根拠に基づいたテーラーメイドのトレーニング・コンディショニング法が不可欠です。私たちは、筋だけでなく、脳の疲労・ストレスに着目し、身心不健全を予防し、最高のパフォーマンスを発揮するための環境要因 (低酸素環境、仮想空間環境 (Virtual Reality: VR))、コンディション評価、トレーニングの方法について研究し、スポーツ現場、社会への応用・実装を目指します。
