目标生长/发育期间握力（GS）变化所涉及的因素尚不清楚。横断面研究的结果表明，手指长度与身体健康有关，包括 GS。本研究旨在使用 4D 作为协变量，调查一年内 GS 变化与幼儿第二 (2D) 和第四 (4D) 手指长度之间的关联。方法 103 名幼儿（54 名男孩和 49 名女孩）进行了最大自愿 GS 和超声测量的右手前臂肌肉厚度测量。所有参与者都完成了第一次测量，并在第一次测量一年后进行了第二次测量。 2D 和 4D 是在第二次测量时在伸出的右手的手掌表面上获取的。结果 2D 与 GS 的变化呈负相关（B= −2.1，p= 0.023），并针对所有协变量进行了调整。女孩的握力调整后的变化在数值上较低，尽管这在统计上并不显着[−0.61 (−1.2, 0.02) kg]。当从模型中删除性别时，2D 仍然与 GS 的变化呈负相关（B= −2.39，p= 0.011）。最后，当仅调整 4D 时，2D 与 GS 的变化呈负相关（B= −3.07，p= 0.004）。结论本研究记录了 1 年内 GS 的变化与幼儿的手指长度之间的关联。儿童手指长度的差异需要被认为是儿童 GS 弱的一个因素。
ObjectivesThe factors involved in changes in grip strength (GS) during growth/development are not well known. Findings from cross‐sectional studies have indicated that digit lengths are associated with physical fitness, including GS. This study aimed to investigate the association of changes in GS over 1 year and the second (2D) and fourth (4D) digit lengths in young children using the 4D as a covariate.MethodsOne hundred and three young children (54 boys and 49 girls) performed maximum voluntary GS and ultrasound‐measured forearm muscle thickness measurements in the right hand. All participants completed the first measurement and underwent a second measurement 1 year after the first one. The 2D and 4D were taken on the palmar surface of the outstretched right hand at the second measurement.ResultsThe 2D was inversely associated with the change in GS (B= −2.1,p= 0.023) adjusted for all covariates. Girls had numerically lower adjusted changes in grip strength, although this was not statistically significant [−0.61 (−1.2, 0.02) kg]. When sex was removed from the model, the 2D remained inversely associated with the change in GS (B= −2.39,p= 0.011). Finally, when only adjusting for the 4D, the 2D was inversely associated with the change in GS (B= −3.07,p= 0.004).ConclusionThis study documented the association between changes in GS over 1 year and digit lengths in young children. The difference in children's digit length needs to be recognized as a factor involved in weak GS in children.
