本研究的目的是比较高强度(HI-SS)和低强度(LI-SS)两种静态拉伸(SS)训练方案对足底屈肌被动和主动特性的影响。将40名健康青年男性随机分为3组：Hi-SS干预组(n=14)、LI-SS干预组(n=13)和非干预对照组(n=13)。采用11分数值评分(0-10；无至非常痛的伸展)来确定SS强度。每周3次，共3组60名S患者，Hi-SS和LI-SS分别以6-7和0-1强度伸展，共4周。在SS训练计划前后评估背屈运动范围、腓肠肌僵硬、肌肉力量、跳跃高度和肌肉结构。HI-SS组在活动度(40比15%)上比Li-SS组改善更多(−57比−24%)，而肌肉力量、跳跃高度和肌肉结构没有明显变化。对照组在任何变量上均无明显变化。在青年男子4周训练后，进行HI-SS训练比LI-SS训练更有效地增加足底屈肌的活动度和降低肌肉僵硬。然而，SS可能不会增加肌肉力量或肥大，无论拉伸不适强度如何。
The purpose of this study was to compare two static stretching (SS) training programs at high-intensity (HI-SS) and low-intensity (LI-SS) on passive and active properties of the plantar flexor muscles. Forty healthy young men were randomly allocated into three groups: HI-SS intervention group (n = 14), LI-SS intervention group (n = 13), and non-intervention control group (n = 13). An 11-point numerical scale (0–10; none to very painful stretching) was used to determine SS intensity. HI-SS and LI-SS stretched at 6–7 and 0–1 intensities, respectively, both in 3 sets of 60 s, 3×/week, for 4 weeks. Dorsiflexion range of motion (ROM), gastrocnemius muscle stiffness, muscle strength, drop jump height, and muscle architecture were assessed before and after SS training program. The HI-SS group improved more than LI-SS in ROM (40 vs. 15%) and decreased muscle stiffness (−57 vs. −24%), while no significant change was observed for muscle strength, drop jump height, and muscle architecture in both groups. The control group presented no significant change in any variable. Performing HI-SS is more effective than LI-SS for increasing ROM and decreasing muscle stiffness of plantar flexor muscles following a 4-week training period in young men. However, SS may not increase muscle strength or hypertrophy, regardless of the stretching discomfort intensity.
