摘要离心训练在预防肌腱损伤中被证明是有效的，然而，长肌肉长度的离心训练对肌腱柔韧性的影响却知之甚少。因此，本研究的目的是评估长肌肉的偏心训练对腿筋肌的柔韧性和被动特性的影响。34名经常运动的年轻人被随机分为对照组和干预组(进行6周的长肌肉偏心肌腱训练；对照组继续进行日常活动)。测量干预前后股二头肌最大被动屈曲活动度(ROM)、被动腿筋硬度、剪切弹性模量和肌腱长度。最大被动髋关节活动度存在显著的时间×组效应。事后测试显示，干预组显著增加(+11.2%；p<；0.001；d=1.55)。此外，松弛位置的剪切模数显示出显著的时间效应(p<；0.001)。其他参数没有显示出显著的交互作用。结果表明，长肌肉长度的偏心腿筋训练能显著提高腿肌腱的柔韧性，这很可能与被动肌腱僵硬或远端肌腱长度的变化无关。
ABSTRACT Eccentric training proved to be effective in hamstring injury prevention; however, little is known about effects of eccentric hamstring training at long muscle length on hamstring flexibility. Hence, the aim was to evaluate the effect of eccentric training at long muscle lengths on flexibility and passive properties of the hamstring muscles. 34 physically active young adults were randomized to either the control or intervention group (6 weeks of eccentric hamstring training at long muscle length; control group resumed with their usual activities). Maximal passive hip flexion range of motion (ROM), passive hamstring stiffness, shear modulus and tendon length of the biceps femoris long head (BFlh) were measured pre- and post-intervention. A significant time × group effect was observed for maximal passive hip ROM. Post-hoc testing revealed a significant increase in the intervention group (+11.2%; p < 0.001; d = 1.55). Additionally, a significant time effect was shown for shear modulus in a relaxed position (p < 0.001). No significant interaction was shown for other parameters. Results indicate that eccentric hamstring training at long muscle length elicits large gains in hamstring flexibility, which are most likely not related to changes in passive hamstring stiffness or BFlh distal tendon length.
