Previous studies have revealed decreased proprioception and perception of joint position in elderly adults. Joint position sense, indicating an individual's ability to perceive the position of limbs without visual aid, is essential for everyday movements. A few studies have shown a positive effect of muscle stretching on joint position sense (JPS). However, these studies have only been conducted with younger participants. The impact of stretching on JPS in elderly adults remains unclear. Therefore, the aim of this study is to compare the acute effects of muscle stretching on joint position sense in young and elderly adults. An experimental group of younger adults ( = 15; 25.4 ± 2.9 years) and an experimental group of active, healthy elderly adults ( = 15; 64 ± 3.5 years) stretched their knee flexor muscles. The absolute error (AE) of the joint position sense was calculated before and after muscle stretching. The results indicated no significant difference in the AE between groups ( > 0.05) after the stretching intervention. The similarity in the physical activity status of the subjects may have influenced the results. Even though no significant age-specific differences were found in this study, its results may not be applicable to non-active elderly adults.
以往的研究表明，老年人的本体感觉和关节位置感知能力有所下降。关节位置觉是指个体在没有视觉辅助的情况下感知肢体位置的能力，对日常活动至关重要。一些研究表明，肌肉拉伸对关节位置觉（JPS）有积极影响。然而，这些研究仅在年轻参与者中进行。拉伸对老年人关节位置觉的影响仍不清楚。因此，本研究的目的是比较肌肉拉伸对年轻人和老年人关节位置觉的急性影响。一组年轻成年人实验组（n = 15；25.4 ± 2.9岁）和一组活跃、健康的老年人实验组（n = 15；64 ± 3.5岁）对其膝屈肌进行了拉伸。在肌肉拉伸前后计算关节位置觉的绝对误差（AE）。结果表明，拉伸干预后两组之间的绝对误差没有显著差异（p > 0.05）。受试者身体活动状态的相似性可能影响了结果。尽管本研究未发现明显的年龄特异性差异，但其结果可能不适用于不活跃的老年人。
