BACKGROUND
There has been a suggested link between muscle strength and arch type of the foot. However, a distinct cause and effect dependence has yet to be established. The purpose of this study was to compare the outcomes from selected explosive strength tests with different arch heights.
MATERIAL AND METHODS
The medial longitudinal arch (MLA) was measured using a Clarke's angle method. Five hundred seventy-four subjects (n = 574) participated in this study and were divided into three arch height groups and three muscle strength groups, respectively. To evaluate the association between longitudinal arch of the foot with the explosive power of lower limb muscles, Chi-square (χ²) test was used.
RESULTS
Arch heights were not significantly related to explosive muscle strength.
CONCLUSIONS
Arch measurement was ineffective in accounting for the observed variability in the explosive strength among young adults.
CLINICAL RELEVANCE
This data may be useful in evaluating patients with painful flat feet and any strength deficits they may have.
背景
有人提出，肌肉力量与足弓类型之间存在关联。然而，尚未确立明确的因果关系。本研究的目的是比较不同足弓高度的特定爆发力测试的结果。
材料与方法
采用 Clarke 角法测量内侧纵弓（MLA）。574 名受试者（n = 574）参与了这项研究，他们分别被分为三组足弓高度和三组肌肉力量。为了评估足部纵弓与下肢肌肉爆发力之间的关系，使用卡方检验（χ² 检验）。
结果
足弓高度与爆发力之间没有显著相关性。
结论
足弓测量不能很好地解释年轻人之间爆发力的可变性。
临床意义
这些数据可能有助于评估有疼痛性扁平足的患者及其可能存在的任何力量缺陷。
