Ó Catháin, CP, Richter, C, and Moran, K. Can directed compliant running reduce the magnitude of variables associated with the development of running injuries? J Strength Cond Res 36(3): 772-780, 2022-Running is one of the most popular modes of activity worldwide and provides numerous health benefits. However, impact forces associated with the foot contacting the ground have been implicated in the development of running related injuries. As such, previous studies have used various methods to alter running to reduce the magnitude of these impact forces. However, it is unclear what kinematic changes facilitate this reduced loading or how loading further up the body changes. In this study, verbal direction was used to teach subjects to run with a more compliant running technique. Kinetic and kinematics characteristics of each subjects "normal" running technique and new "compliant technique" were measured in a fatigued and unfatigued state. Energy expenditure of each running style was also measured. Verbally directed compliant running significantly decreased (17%) vertical ground reaction force impact peaks, sacral (41%) and head (28%) impact accelerations, and increased energy expenditure (21%), in comparison with normal running. Findings suggest that verbally directed compliant running may reduce the magnitude of variables associated with the development of running injuries.
奥卡坦恩、CP、里希特、C 和莫兰、K. 有针对性的顺应性跑步能否降低与跑步损伤发展相关变量的幅度？J 力量与调节研究 36(3):772-780, 2022-跑步是全球最受欢迎的活动方式之一，提供了众多健康益处。然而，与脚接触地面相关的冲击力量已被牵连到跑步相关损伤的发展中。因此，先前的研究已经使用各种方法改变跑步方式来降低这些冲击力量的幅度。然而，尚不清楚哪些运动学变化促进了这种减少的负荷，或者身体的其他部位如何进一步改变负荷。在这项研究中，使用口头指令来教授受试者采用更顺应性的跑步技术。在疲劳和非疲劳状态下，测量每个受试者“正常”跑步技术和新的“顺应性技术”的运动学和运动学特征。还测量了每种跑步方式的能量消耗。与正常跑步相比，口头指导的顺应性跑步显著降低了（17%）垂直地面反作用力冲击峰值、骶骨（41%）和头部（28%）冲击加速度，并增加了能量消耗（21%）。研究结果表明，口头指导的顺应性跑步可能会降低与跑步损伤发展相关变量的幅度。
