The effect of running training on running kinematics and kinetics in novice runners has not yet been investigated. Previous studies have shown that novice runners are less economical and more prone to injury compared to well-trained runners. Since running economy (RE) and running injury risk have been associated with biomechanical variables that may be trainable, the purpose of this study was to determine the effect of a 12-week training program for beginners on running kinematics and kinetics. It was hypothesised that participants would evolve towards running kinematics and kinetics that have previously been associated with better RE and lower injury risk. 27 participants underwent a full-body, three-dimensional running analysis before and after a 12-week running program. Outcome variables included peak joint angles, joint moments, and ground reaction forces (GRF) in three planes. After training, hip external rotation moment increased significantly with 0.01 Nm/kg. Peak vertical GRF decreased with 0.9 N/kg (4.05%). There were no significant changes in peak joint angles. In conclusion, results show that a 12-week running program for beginners aimed to increase running endurance does not lead to changes in running kinematics or kinetics that have previously been associated with better RE and lower injury risk.
跑步训练对新手跑步者的跑步运动学和动力学的影响尚未被研究。先前的研究表明，新手跑步者与训练有素的跑步者相比，效率较低，更容易受伤。由于跑步经济性（RE）和跑步受伤风险与可能可训练的生物力学变量有关，本研究的目的是确定为期 12 周的新手训练计划对跑步运动学和动力学的影响。假设参与者将朝着以前与更好的 RE 和更低的受伤风险相关的跑步运动学和动力学发展。27 名参与者在进行为期 12 周的跑步计划前后接受了全身三维跑步分析。结果变量包括三个平面的关节峰值角度、关节力矩和地面反作用力（GRF）。训练后，髋关节外旋力矩增加了 0.01 Nm/kg。峰值垂直 GRF 下降了 0.9 N/kg（4.05%）。关节峰值角度没有明显变化。总之，结果表明，旨在提高跑步耐力的 12 周新手跑步计划不会导致以前与更好的 RE 和更低的受伤风险相关的跑步运动学或动力学的变化。
