オランダ代表SBバンデンハークがWBCに意欲「2013年以上の成績を残せる」 海外 2017.01.20 2018.01.16 バンデンハークがインスタグラムにアップしたトレーニング風景 #Repost @paulvenner with @repostapp ・・・ For good movement, #stability is key. In #pitching, a stable foot placement is very important. Not only to prevent from injury but also to improve the direction of the ground reaction forces to propel the body and the ball forward. To train this, we need strong hamstrings in their optimum length and optimal energy transfer through the kinetic chain under changing conditions with unstable loads.
