In recent years, there has been rising interest and debate on the importance of addressing running mechanics for preventing running-related hamstring injury. It is a logical and intriguing avenue of research given the high prevalence of such injuries. In theory, lower-limb mechanics directly relate to hamstring musculotendinous demands when running—the relative positions of the hip and knee joints, and pelvic tilt, will determine the hamstring muscle–tendon unit (MTU) lengths. Notably, hamstring MTUs during running are subject to large strain and force during late swing. However, there is a paucity of research prospectively investigating the relationship between running mechanics, or hamstring MTU dynamics, and injury, likely because it is challenging to prospectively obtain large samples of data from injured athletes. To better understand the relationship between running mechanics and hamstring injury, it can be useful to examine multiple case studies (or case series), the advantage being they offer constructive observation(s) towards novel concepts in ecologically valid contexts. Schuermans et al 1 found that four injured soccer players displayed greater anterior pelvic tilt during mid-swing and greater thoracic lateral flexion during the late swing phase of sprinting. Similarly, in a study of three rugby players2 who subsequently sustained hamstring injuries, a tendency for greater thoracic lateral flexion during the late swing phase as well as greater knee power absorption and hip extension moments was observed. As noted earlier, given the attachment sites of …

接下来去哪里锻炼腘绳肌？生物力学和解剖学的角度

近年来，人们对解决跑步力学问题以预防与跑步相关的腿筋损伤的重要性越来越感兴趣和争论。鉴于此类伤害的发生率很高，这是一个合乎逻辑且有趣的研究途径。理论上，下肢力学与跑步时腘绳肌腱的需求直接相关——髋关节和膝关节的相对位置以及骨盆倾斜将决定腘绳肌肌腱单位（MTU）的长度。值得注意的是，跑步过程中的腿筋 MTU 在后期摆动过程中会受到很大的应变和力量。然而，很少有研究前瞻性地调查跑步力学或腿筋 MTU 动力学与损伤之间的关系，这可能是因为前瞻性地从受伤运动员那里获取大量数据样本具有挑战性。为了更好地理解跑步力学和腿筋损伤之间的关系，检查多个案例研究（或案例系列）可能很有用，其优点是它们为生态有效背景下的新概念提供了建设性观察。Schuermans 等人 1 发现，四名受伤的足球运动员在冲刺的挥杆中期表现出更大的骨盆前倾，在冲刺的挥杆后期表现出更大的胸椎侧屈。同样，在对三名随后腿筋受伤的橄榄球运动员2进行的研究中，观察到在挥杆后期胸椎侧屈更大的趋势以及更大的膝盖能量吸收和髋部伸展力矩。如前所述，考虑到……的附着位点
