本研究调查了以相同负荷但使用两种方案（高强度、短时间和低强度、长时间）进行静态拉伸（SS）对运动范围（ROM）和肌肉僵硬度的影响。共有18名健康学生参加了这项研究。他们随机进行高强度和短时间（120%和100秒）或低强度和长时间（50%和240秒）的SS。结果进行了评估的ROM，被动扭矩背屈ROM和剪切弹性模量的内侧腓肠肌之前和之后的静态拉伸。结果表明，与拉伸前相比，高强度短时间拉伸后的ROM显著增加[+6.1° ± 4.6°（Δ25.7 ± 19.9%）]，低强度长时间拉伸后的ROM显著增加[+3.6° ± 2.3°（Δ16.0 ± 11.8%）]。高强度短时间拉伸后的ROM显著高于低强度长时间拉伸后的ROM。在高强度和短时间条件下[+5.8 ± 12.8 Nm（Δ22.9 ± 40.5%）]和低强度和长时间条件下[+2.1 ± 3.4 Nm（Δ6.9 ± 10.8%）]，背屈ROM的被动扭矩均显著增加，但两种条件之间未观察到显著差异。剪切弹性模量在高强度和短时间[-8.8 ± 6.1 kPa（Δ-38.8 ± 14.5%）]和低强度和长时间[-8.0 ± 12.8 kPa（Δ-22.2 ± 33.8%）]条件下均显著降低。此外，剪切弹性模量的相对变化在高强度和短时间的SS显着大于在低强度和长时间的SS。我们的研究结果表明，应进行更高强度的静态拉伸，以增加ROM和降低肌肉刚度，即使是很短的时间。
This study investigated the effects of static stretching (SS) delivered with the same load but using two protocols – high-intensity and short-duration and low-intensity and long-duration – on range of motion (ROM) and muscle stiffness. A total of 18 healthy students participated in the study. They randomly performed high-intensity and short-duration (120% and 100 s) or low-intensity and long-duration (50% and 240 s) SS. Outcomes were assessed on ROM, passive torque at dorsiflexion ROM, and shear elastic modulus of the medial gastrocnemius before and after static stretching. The results showed that ROM increased significantly at post-stretching compared to that at pre-stretching in both high-intensity and short-duration [+6.1° ± 4.6° (Δ25.7 ± 19.9%)] and low-intensity and long-duration [+3.6° ± 2.3° (Δ16.0 ± 11.8%)]. Also, the ROM was significantly higher at post-stretching in high-intensity and short-duration conditions than that in low-intensity and long-duration. The passive torque at dorsiflexion ROM was significantly increased in both high-intensity and short-duration [+5.8 ± 12.8 Nm (Δ22.9 ± 40.5%)] and low-intensity and long-duration [+2.1 ± 3.4 Nm (Δ6.9 ± 10.8%)] conditions, but no significant differences were observed between both conditions. The shear elastic modulus was significantly decreased in both high-intensity and short-duration [−8.8 ± 6.1 kPa (Δ − 38.8 ± 14.5%)] and low-intensity and long-duration [−8.0 ± 12.8 kPa (Δ − 22.2 ± 33.8%)] conditions. Moreover, the relative change in shear elastic modulus in the high-intensity and short-duration SS was significantly greater than that in low-intensity and long-duration SS. Our results suggest that a higher intensity of the static stretching should be conducted to increase ROM and decrease muscle stiffness, even for a short time.
