跑步者有时会被建议改变他们的击球模式，作为提高成绩或应对受伤的一种手段。本研究的目的是比较下肢力学的后脚前锋（RFS），谁被指示运行与前脚罢工模式（CFFS）的首选前脚前锋（FFS）。评价了9个FFS和9个CFFS的三维力学性能。大多数运动学和动力学变量和所有运动模式的峰值在CFFS和FFS之间没有统计学差异。在CFFS组中，只有峰值垂直地面反作用力和峰值踝跖屈力矩显著较低（p小于或等于0.05）。这表明RFS能够假设FFS模式，而很少有实践与首选FFS模式非常相似。改变运动员的击球方式对运动损伤风险和运动成绩的影响有待进一步研究。
Runners are sometimes advised to alter their strike pattern as a means of increasing performance or in response to injury. The purpose of this study was to compare lower extremity mechanics of rearfoot strikers (RFS), who were instructed to run with a forefoot strike pattern (CFFS) to those of a preferred forefoot striker (FFS). Three-dimensional mechanics of 9 FFS and 9 CFFS were evaluated. Peak values for most kinematic and kinetic variables and all patterns of movement were not found to be statistically different between CFFS and FFS. Only peak vertical ground reaction force and peak ankle plantarflexion moment were found to be significantly lower (p less than or equal to .05) in the CFFS group. This suggests that RFS are able to assume a FFS pattern with very little practice that is very similar to that of a preferred FFS. The impact of changing one's strike pattern on injury risk and running performance needs further study.
