Objectives
Narrative objectives1 The purpose of this study is to clarify the acute effects of static stretching (SS) and cyclic stretching (CS) performed at the same speed on the contraction response of the triceps surae muscle and the recovery time after muscle fatigue.
In addition, two types of stretching are performed for 4 weeks, showing the physiological effects on muscle contraction response and recovery time after muscle fatigue, and confirming the effect on physical performance. Clarify the effects of each stretching and establish a new stretching method that leads to recovery after sports activities.
