本研究的目的是比较选择的生物力学变量之前和之后的长距离运行，并评估每周运行量和下肢生物力学的变化之间的关系运行后。12名训练过的习惯性后足着地的男性跑步者在跑步机长跑前后跑过地面，同时记录运动学和动力学数据。重复测量方差分析和科恩的d效应大小被用来比较运动学和动力学变量之前和之后的运行。运行后的负荷率高6%（p <0.05），但这种差异具有较小的效应量（d = 0.32）。中度影响被发现为25%的峰值踝关节外翻（d = 0.62）和髋关节内收（d = 0.60）后运行增加10%。这些研究结果表明，完成一个次极量长跑不会产生潜在的伤害下肢生物力学在未受伤的后脚罢工的跑步者。每周跑步里程与长跑前后观察到的生物力学变化无关。由于长跑运动员的生物力学反应各不相同，因此在未来的研究中应考虑其他因素的差异，如特定的训练方案和神经肌肉控制。
The purposes of this study were to compare selected biomechanical variables before and after a long run, and to assess the relationship between weekly running volume and changes in lower limb biomechanics after the run. Twelve trained habitual rearfoot strike male runners ran overground before and after a treadmill long run while kinematic and kinetic data were recorded. Repeated measures analysis of variance and Cohen's d effect sizes were used to compare kinematic and kinetic variables before and after the run. Loading rate was 6% higher after the run (p < .05) but this difference had a small effect size (d = .32). Moderate effects were found for a 25% increase in peak ankle eversion (d = 0.62) and a 10% increase in hip adduction (d = 0.60) after the run. These findings suggest that the completion of a submaximal long run does not yield potentially injurious lower limb biomechanics in uninjured rearfoot strike runners. Weekly running mileage was not correlated to biomechanical changes observed before and after the long run. Since biomechanical responses to the long run varied among runners, differences in other factors such as specific training regimens and neuromuscular control should be considered in future studies.
