vol.38ランナーのための筋肉と力学入門 。〜下りの筋損傷、腕振りの謎、大臀筋の科学まで〜

トレイルの下りはなぜ翌日筋肉痛がヤバいのか。上りとの違いは？腕を振らないと遅くなるのか？大きいお尻はランニングに本当に有効？？——今回は最近自分が調べ直していたことをかい摘んで、否 、網羅的に調べて喋ってみました。talked about...・下り坂はエキセントリック少年ボーイ、構造的損傷・腕振り止めるといいことない。・エリートスプリンターのケツは普通の人の67%もデカい。ほぼ大人と子供か。・長距離ランナーでは？感覚だけに頼らず、なぜそのフォーム・トレーニングが効くのかを科学的根拠から理解したいランナー・コーチ必聴の回...というか自分への回です。今回収録してみてわかったことは、喋りながら身振り手振り動いていたのでトレーニング系は動画で撮って説明すべきだったなということです押忍！参考文献は以下概要欄■ 下り坂・上り坂と筋損傷Lu et al.
