Different initial length of muscle caused by different starting Angle in varied range isokinetic testing is an important factor that influences muscle function as a prepositional effect.
变幅等速测试中由于起始角不同造成的肌肉收缩初长度各异是影响肌肉功能的重要因素,是一种前置效应。
AIM: to detect the muscle strength and endurance of healthy young people with different sport levels using isokinetic testing technique, so as to explore the characteristics of trunk muscle function.
