Development of Water-based Exercise Programs.

本研究采用步频(SF)和生理反应(如心率、心率)相匹配的运动强度，对水中跑步和旱地跑步机(TMR)中的肌肉活动进行了研究。水中跑时，与TMR相比，水中跑时的腿部肌肉活动相似(即股二头肌和胫前肌)，而低于TMR(股直肌和腓肠肌)。此外，建议在水中跑步时，除了腓肠肌之外，配对的心率可以产生与TMR相似的下肢肌肉活动。

This study investigated muscle activity during running in water and treadmill running on dry land(TMR) when exercise intensity was matched using stride frequency(SF) and physiological responses(e. g., heart rate, HR). It was observed that lower extremity muscle activity during running in water was similar(i. e., biceps femoris and tibialis anterior) and lower(i. e., rectus femoris and gastrocnemius) than that of TMR at matched SF. Furthermore, it was suggested that matching HR can be recommended to produce similar magnitude of lower extremity muscle activity during running in water to that of TMR, with the exception of the gastrocnemius.
