北台灣體育班及非體育班學生的足部結構差異調查

Abstract

目的：比較同樣年齡層體育班及非體育班學學生的足部結構包括足弓指標與拇趾外翻角度，以觀察承受不同程度運動活動強度是否會影響足部結構。方法：以國中、高中與大學體育班及非體育班學生為受試對象，蒐集受測者足印，以電腦軟體分析足弓指標 (arch index)，以量角器測量拇趾外翻角度，以國際體能活動量表計算每週身體活動當量。使用雙因子變異數分析的統計方法分析體育班及非體育班的差異，以及國中、高中及大學學生的學級差異是否影響足弓指標即拇趾外翻。結果：體育班學生有較高的每週身體活動當量，有較高的足弓指標以及較大的拇趾外翻程度。結論：在長期高強度的體能活動下可能使得足部產生結構改變，變得較為扁平以及有較大的拇趾外翻角度，此改變在合理的生理範圍，尚未達到病理性變化程度。

Purpose：Comparing difference of foot structure between students at same school age but with different level of physical activity intensity. Methods: Healthy junior high school, senior high school, and college students were included and classified into athletic class students group and non-athletic class students group. Harris Mat foot print measure device were used to collect subject’s foot print and Arch index(AI) is used to classify foot arch. Hallux valgus angle was measured by a goniometer. Physical activities level was measured by International Physical Activities Questionare (IPAQ). All data were analyzed by two-ways analysis of variance (ANOVA). Results: Statistically difference were noted between athletic class students and non-athletic class students. Athletic students have higher physical activities level, arch index and hallux valgus angle. Conclusions: The result of this study showed that athletic class students have lower foot arch and larger halluxs valgus angle comparing to non-athletic students. The result implies that students could have long term foot structural change under high intensity of physical activity.
