站立、騎自行車與跑步對足弓指數的影響

Abstract

The functions of the foot and leg depend on several structural characteristics of the foot, of which the height of the medial longitudinal arch is the most important. This height is most commonly measured by using the arch index. However, the relation between arch height and leg injury in athletes is unclear. The purpose of this study was to determine the effect of various sport-related activities on the foot arch index.Seventeen college students (nine women and eight men) with no history of leg surgery or trauma were recruited for this study. Each subject participated in three 20-minute sessions over a period of several weeks involving a different sports activity for each session. The activities included standing, stationary biking, and running on a treadmill. The order of activities for each subject was randomly assigned. The arch indices of both feet were measured before and after each subject performed the activity by using a capacitance-based pressure platform (Tekscan(superscript ®) HR-mat). The minimum interval between each session was 5 days. Three activities had significantly different effect on the right as well as left foot arch indices (by repeated measure ANOVA), but there was no significant difference between the post-activity mean arch indices of the right and left feet. The mean foot arch indices after biking were significantly lower in both feet than those measured after either standing or running. Different sport-related activities thus may have different effects on the foot arch indices. In order to investigate possible associations between foot arch height and sports-related lower extremity injury, sport-specific arch indices should be used as reference values.
