本研究的目的是检查不同的动态运动干预对腘绳肌性能的急性影响。36名腿筋柔韧性差的年轻男性被随机分配到三个干预组：慢跑结合动态开放动力链拉伸（DS），慢跑结合动态封闭动力链拉伸（弓步与偏心腿筋风车，LEC），和慢跑（CON）组。在运动干预之前和之后立即记录腘绳肌柔韧性、肌肉刚度（曲线下面积，AUC）、关节位置感（JPS）、最大离心力量（ECC）和峰值扭矩角（APT）。结果表明：DS训练后，腘绳肌柔韧性提高（p < 0.001），肌肉僵硬度降低，且低于慢跑训练（p < 0.001）。此外，LEC中的ECC增加，高于慢跑和DS（p < 0.001）。三组间APT差异有显著性（P < 0.001）。在DS和慢跑中发现JPS的准确性降低（p < 0.001）。总之，动态闭合动力链拉伸（LEC）相比，开放动力链拉伸（DS）或慢跑组，可能是一种有效的技术，以提高肌肉性能在赛前热身程序。
The purpose of the study was to examine the acute effects of different dynamic exercise interventions on hamstring muscle performance. Thirty-six young men with poor hamstring flexibility were randomly assigned to three intervention groups: jogging combined with dynamic open kinetic chain stretching (DS), jogging combined with dynamic closed kinetic chain stretching (lunge with eccentric hamstring windmills, LEC), and jogging only (CON) groups. Hamstring flexibility, muscle stiffness (area under the curve, AUC), joint position sense (JPS), maximal eccentric strength (ECC), and angle of peak torque (APT) were recorded before and immediately after the exercise interventions. The results showed that the hamstring flexibility increased in DS (p < 0.001); muscle stiffness decreased in DS and was lower than jogging (p < 0.001). Moreover, ECC increased in LEC and was higher than jogging and DS (p < 0.001). APT was different among 3 groups (p < 0.001). Decreased accuracy of JPS was found in DS and jogging (p < 0.001). In conclusion, the dynamic closed kinetic chain stretching (LEC) as compared to open kinetic chain stretching (DS) or jogging group, may be an effective technique to enhance muscle performance during the pre-competition warm-up routine.
