Abstract

BACKGROUND

The primary goal of this study was to investigate the relationship between body composition and motor coordination performance, and the secondary goal was to determine sex differences in body composition and motor coordination of preschool children.

METHODS

Forty-eight children (23 boys and 25 girls) underwent assessments for body composition and motor coordination using the Köperkoordinationstest für Kinder (KTK).

RESULTS

Linear regression analysis revealed significant associations between body composition and motor coordination in boys ( < 0.05) but not in girls. In boys, Body height ( = 0.01), Total muscle mass ( = 0.03), Total fat ( = 0.03), and Total water ( = 0.02) show statistically significant influence on single-leg jumps. Similar results were obtained for lateral jumps where there was a statistically significant influence of Body height ( = 0.01), Total muscle mass ( = 0.03), and Total water ( = 0.02). Interestingly, predictive variables showed no statistically significant influence on KTK overall score in boys ( = 0.42) nor in girls ( = 0.90).

CONCLUSIONS

The predictive system of morphological variables demonstrated significance only among boys in this age group and sample. Girls outperformed boys due to early maturation, resulting in better average KTK scores.

摘要

背景

本研究的主要目的是调查身体成分与运动协调能力之间的关系，次要目的是确定学龄前儿童身体成分和运动协调能力的性别差异。

方法

48名儿童（23名男孩和25名女孩）使用儿童运动协调测试（KTK）进行了身体成分和运动协调能力评估。

结果

线性回归分析显示，男孩的身体成分与运动协调能力之间存在显著关联（<0.05），而女孩则不然。在男孩中，身高（=0.01）、总肌肉量（=0.03）、总脂肪（=0.03）和总水量（=0.02）对单腿跳跃有统计学上的显著影响。横向跳跃也得到了类似的结果，身高（=0.01）、总肌肉量（=0.03）和总水量（=0.02）有统计学上的显著影响。有趣的是，预测变量对男孩（=0.42）和女孩（=0.90）的KTK总分均无统计学上的显著影响。
