有规律的身体活动是儿童身体健康的重要组成部分，并且与增加骨骼肌质量和肌肉力量有关。身体活动水平低的儿童可能会在以后的生活中遇到健康问题，例如肌肉质量的损失。因此，它可能是有价值的，以确定下降的身体功能的儿童谁不执行推荐量的体力活动。因此，我们的目的是评估幼儿每周≥5天每天进行≥60分钟的体力活动量与骨骼肌质量指数和身体功能之间的关系。这项横断面研究共纳入了340名6-12岁的典型发育儿童（175名女孩;平均年龄为9.5±1.9岁）。我们评估了每周至少5天每天进行建议的至少60分钟中度至剧烈体育活动的儿童比例。评价骨骼肌质量和步态偏差指数评分、步态速度、握力、五次坐立测试结果、定时起身行走测试结果、单腿站立时间和步态效率。在控制了混杂因素（年龄和性别）后，进行多因素logistic回归分析，以评估中度至剧烈体力活动与骨骼肌质量指数、体脂百分比和身体功能的相关性。Logistic回归分析显示，骨骼肌质量指数与中度至剧烈体力活动独立相关（比值比，2.34; 95%置信区间，1.17-4.71; P = 0.017）。每周≥5天、每天≥60分钟的中度至剧烈体力活动与日本儿童的骨骼肌质量指数评分相关。我们的研究结果强调了进行中度到剧烈的体力活动对儿童骨骼肌质量发展的重要性。
Regular physical activity is an important component of physical health of children and has been associated with increasing skeletal muscle mass and muscle strength. Children with low levels of physical activity may experience health problems, such as loss of muscle mass, later in life. Thus, it may be valuable to identify declining physical function in children who do not perform the recommended amount of physical activity. Therefore, we aimed to evaluate the relationship between the amount of physical activity performed for ≥60 min per day for ≥5 days per week and the skeletal muscle mass index and physical function in young children. In total, 340 typically developing children aged 6–12 years (175 girls; average age, 9.5±1.9 years) were included in this cross-sectional study. We evaluated the proportion of children performing the recommended minimum of 60 min of daily moderate-to-vigorous physical activity at least 5 days per week. The skeletal muscle mass and Gait Deviation Index scores, gait speed, grip strength, Five Times Sit-to-Stand test results, Timed Up-and-Go test results, one-leg standing time, and gait efficiency were evaluated. Multiple logistic regression analyses were performed to assess the association of moderate-to-vigorous physical activity with the skeletal muscle mass index, percent body fat, and physical function, after controlling for confounding factors (age and sex). A logistic regression analysis revealed that the skeletal muscle mass index was independently associated with moderate-to-vigorous physical activity (odds ratio, 2.34; 95% confidence interval, 1.17–4.71; P = 0.017). Performance of moderate-to-vigorous physical activity for ≥5 days per week for ≥60 min per day was associated with the skeletal muscle mass index score of Japanese children. Our findings highlighted the importance of performing moderate-to-vigorous physical activity for the development of skeletal muscle mass in children.
