Running is a highly physical activity, and it is related to injuries when there is an excessive pronation of the foot. This study evaluates, from a sample group of healthy recreational runners, if the foot tends to pronate after a period of running activity and when, with respect to a period of running compared to walking, evaluated during several phases: after 30, 45, and 60 min. This quasi-experimental study has been carried out on a total of 36 healthy recreational subjects. The subjects were evaluated during two different activities: running activity for a period of an hour with respect to normal walking activity. The main outcome measures were the foot posture index (FPI) and the navicular drop test (NDT), which were evaluated at p1 (the screening day), after 30 min of activity (p2), after 45 min of activity (p3), and finally after 60 min (p4) during running or walking activity. The analysis showed significant differences for the FPI and NDT variables in both groups and on both feet, comparing p1 and p4. These changes showed a significant relationship comparing p1 and p3 for the FPI variable, and for the NDT variable ( < 0.001) of the left foot and, with respect to the right foot, significance was shown to the FPI comparing the p1 and p2. A significant difference was found in the tendency to pronate the foot after a period of running compared to the same period of walking after 60 min of activity. Running produced an excessive pronation of the foot after 45 min of activity, evaluated with the FPI for both feet.
跑步是一项高强度的体力活动，当足部过度内旋时会导致受伤。本研究从一组健康的业余跑步者样本中评估，在一段时间的跑步活动后足部是否倾向于内旋，以及与步行一段时间相比，在跑步的几个阶段（30分钟、45分钟和60分钟后）足部何时会出现内旋。这项准实验研究共对36名健康的业余受试者进行。受试者在两种不同活动期间接受评估：一小时的跑步活动与正常步行活动。主要观察指标是足姿势指数（FPI）和舟骨下降试验（NDT），在跑步或步行活动期间的p1（筛查日）、活动30分钟后（p2）、活动45分钟后（p3）以及最后60分钟后（p4）进行评估。分析表明，比较p1和p4时，两组和双脚的FPI和NDT变量均存在显著差异。对于FPI变量，比较p1和p3时这些变化显示出显著关系，对于左脚的NDT变量（<0.001），比较p1和p2时右脚的FPI显示出显著关系。在活动60分钟后，与相同时间段的步行相比，跑步一段时间后足部内旋的倾向存在显著差异。用FPI评估，活动45分钟后跑步导致双脚出现过度内旋。
