The purpose of the present investigation was to examine the effects of a repeated eccentric exercise on position sense and muscle reaction angle. Fourteen healthy women underwent an isokinetic exercise session on their knee flexors, which was repeated after 4 weeks. Muscle damage indices, position sense and joint reaction angle of the knee were examined before, immediately after, as well as at 1, 2, 3, 4 and 7 days after exercise. The second exercise bout induced significantly lesser effects in all muscle damage indices as well as lesser disturbances in position sense and reaction angle when compared to the first one. The main finding of this study is that position sense and joint reaction angle to release of the lower limbs may adapt in response to a repeated bout of eccentric exercise, leading to less disturbances in position sense and reaction angle after the second bout of exercise.
本研究的目的是探讨重复进行离心运动对位置觉和肌肉反应角度的影响。14名健康女性对其膝屈肌进行了一次等速运动训练，并在4周后重复进行。在运动前、运动后即刻以及运动后1、2、3、4和7天检测膝关节的肌肉损伤指标、位置觉和关节反应角度。与第一次运动相比，第二次运动引起的所有肌肉损伤指标的影响明显较小，位置觉和反应角度的干扰也较小。本研究的主要发现是，下肢放松时的位置觉和关节反应角度可能会因重复进行离心运动而产生适应性变化，从而使第二次运动后位置觉和反应角度的干扰减少。
