The overall purpose of this study was to examine the relationship between motor proficiency and health-related fitness in children. In addition, the study aimed to determine if particular combinations of motor skills have a stronger relationship with individual health-related fitness measures.
Seventy-seven children (F:28, M:49) (mean age: 11.19 ± 2.74 years) participated in this prospective cohort study. Physical measures included the following: motor proficiency (Bruininks-Oseretsky Test of Motor Proficiency, Second Edition), body mass index (BMI), waist circumference, blood pressure, heart rate and VO(2) peak (mL/kg/min).
After factoring in age, motor proficiency as a combined total score had a strong negative relationship with the health-related fitness measures of BMI (r (2) = 0.62, P < 0.001) and waist circumference (r (2) = 0.72, P < 0.001) and a strong positive relationship with VO2 peak (r (2) = 0.78, P = 0.002). Children with lower motor proficiency (≤25th percentile) had a significantly larger mean waist circumference (M = 13.85 cm, 95% confidence interval (CI) (2.05, 25.66), P = 0.01), heavier weight (M = 22.17 kg, 95% CI (2.44, 41.91), P = 0.02) and higher BMI (M = 5.10 kg/m(2) , 95% CI (0.33, 9.87), P = 0.03) than children with higher motor proficiency (≤75th percentile).
Motor proficiency, once corrected for age, is significantly related to a number of health-related measures in children and should therefore be considered a focus for investigation for children with poor health-related fitness (e.g. high BMI and waist circumference percentiles or low cardiorespiratory fitness), as motor incompetence could be an underlying contributing factor to a child's poor physical health.
本研究的总体目的是探讨儿童运动能力与健康相关体能之间的关系。此外，该研究旨在确定特定的运动技能组合是否与个体健康相关体能指标有更强的关系。
77名儿童（女性28名，男性49名）（平均年龄：11.19 ± 2.74岁）参与了这项前瞻性队列研究。身体测量指标包括：运动能力（布鲁宁克斯-奥塞瑞斯基运动能力测试第二版）、体重指数（BMI）、腰围、血压、心率和最大摄氧量（毫升/千克/分钟）。
在考虑年龄因素后，运动能力综合总分与BMI（r² = 0.62，P < 0.001）和腰围（r² = 0.72，P < 0.001）等健康相关体能指标呈强负相关，与最大摄氧量呈强正相关（r² = 0.78，P = 0.002）。运动能力较低（≤第25百分位数）的儿童，其平均腰围（M = 13.85厘米，95%置信区间（CI）（2.05，25.66），P = 0.01）、体重（M = 22.17千克，95% CI（2.44，41.91），P = 0.02）和BMI（M = 5.10千克/米²，95% CI（0.33，9.87），P = 0.03）均显著高于运动能力较高（≤第75百分位数）的儿童。
校正年龄后，运动能力与儿童的多项健康相关指标显著相关，因此对于健康相关体能较差（如高BMI和腰围百分位数或低心肺适能）的儿童，运动能力应被视为一个调查重点，因为运动能力不足可能是儿童身体健康不佳的一个潜在因素。
