Midfoot- (MFS) and forefoot-striking (FFS) runners usually switch to rearfoot-striking (RFS) during marathons. However, world-class runners might resist modifications during shorter races. The purpose of this study was to analyse footstrike patterns, ground contact times and running speeds in a World Championship men's 10,000 m final. Footstrike patterns and contact times of the top 12 finishing men (24 ± 5 years) were recorded (150 Hz) during laps 1, 5, 11, 15, 20 and 25. Split times for each 100-m segment were obtained. No RFS patterns were observed; there was no difference between the number of FFS and MFS athletes at any distance (p ≥ 0.581) and no change in the proportions of FFS and MFS occurred (p = 0.383). No link between race performance and footstrike pattern appeared given the similar number who used FFS or MFS and their similar finishing times. Despite slower running speeds and longer contact times in the middle of the race (p ≤ 0.024), no effect on footstrike patterns occurred. The prevalence of anterior footstrike patterns in this world-class race reflects the capability of maintaining fast paces (>22 km/h). Changes in footstrike pattern might accompany the physiological and neuromuscular effects of fatigue over longer distances.
中足(MFS)和前足着地(FFS)的跑步者通常在马拉松比赛中切换到后足着地(RFS)。然而,世界级的跑步者可能在较短的比赛中抵制改变。本研究的目的是分析世界锦标赛男子 10,000 米决赛中的足着地模式、地面接触时间和跑步速度。记录了前 12 名完成比赛的男子(24 ± 5 岁)在第 1、5、11、15、20 和 25 圈时的足着地模式和接触时间(150 Hz)。获得了每个 100 米段的分段时间。没有观察到 RFS 模式;在任何距离上,FFS 和 MFS 运动员的数量都没有差异(p ≥ 0.581),FFS 和 MFS 的比例也没有变化(p = 0.383)。考虑到使用 FFS 或 MFS 的人数相似且完成时间相似,比赛成绩与足着地模式之间似乎没有联系。尽管在比赛中段跑步速度较慢且接触时间较长(p ≤ 0.024),但足着地模式没有受到影响。在前世界级比赛中,前足着地模式的流行反映了保持快速步伐(>22 公里/小时)的能力。在更长的距离上,足着地模式的改变可能伴随着疲劳的生理和神经肌肉影响。
