Little evidence has been provided regarding physical performance and flat-footedness in school-age children. Although flat feet may decrease the level of motor performance, findings remain inconsistent. Therefore, the main purpose of the study was to determine whether children with flat feet had poorer physical task performance, compared to normal-footed children.
A total of 208 primary school boys were included in the study (107 normal-footed and 101 flatfooted boys). Flat footedness (< 42°) was determined using Clark's method. The children were tested by a set of unilateral and bilateral tests selected from the area of explosive power and dynamic balance which included: (i) countermovement jump, (ii) standing broad jump, (iii) the triple crossover hop for distance test, (iv) maximal sprinting speed over 10, 20 and 40 m and (v) the Star Excursion Balance Test. Differences were adjusted for age, body mass index, peak height velocity and physical activity.
Flat footed children exhibited significantly poorer results in bilateral standing broad jump (effect size [ES] = 0.34), unilateral standing broad jump for dominant (ES = 0.31) and non-dominant leg (ES = 0.20), the triple crossover hop for distance test for dominant (ES = 0.24) and non-dominant leg (ES = 0.23) and the Star Excursion Balance Test (ES = 0.23-0.43) and were slower in maximal sprinting speed test over 20 m (ES = 0.25) and 40 m (ES = 0.30).
This study shows that children with flat feet performed poorer in some physical performance tasks, compared to the normal feet counterparts.
关于学龄儿童的身体表现和扁平足，几乎没有提供什么证据。虽然扁平足可能会降低运动表现水平，但研究结果仍不一致。因此，本研究的主要目的是确定扁平足儿童的身体任务表现是否比正常足儿童差。
本研究共纳入 208 名小学男生（107 名正常足和 101 名扁平足男孩）。采用克拉克法确定扁平足。通过从爆发力和动态平衡领域选择的一组单侧和双侧测试来测试儿童，包括：（i）反跳式纵跳，（ii）站立式跳远，（iii）三向交叉跳远距离测试，（iv）10、20 和 40 米最大冲刺速度，（v）星形伸展平衡测试。差异调整了年龄、体重指数、峰值身高速度和体力活动。
扁平足儿童在双侧站立跳远（效应大小[ES] = 0.34）、单侧站立跳远（ES = 0.31）和非优势腿（ES = 0.20）、三向交叉跳距离测试（ES = 0.24）和非优势腿（ES = 0.23）以及星形伸展平衡测试（ES = 0.23-0.43）的表现明显较差，在 20 米（ES = 0.25）和 40 米（ES = 0.30）最大冲刺速度测试中速度较慢。
本研究表明，与正常足儿童相比，扁平足儿童在一些身体表现任务中表现较差。
