目的确定健康男孩的体力活动以及体力活动与训练和每日清醒时间的关系研究设计在66名冰球俱乐部的男孩（5 - 15岁）中，我们测量了每日总能量消耗（TDEE，双标记水）和基础代谢率（通风罩法）。通过加速度计和活动方案测量全天（DAEE）、训练期间和自发体力活动期间的体力活动能量消耗。结果青春期前（2.0和2.2 Mcal/d）和青春期（骨龄≥ 13岁）的体力活动水平、DAEE和TDEE;和2.8 Mcal/d）的男孩与文献中同龄的挪威男孩的数据相匹配。青春期前男孩DAEE与清醒时间呈正相关（r（UA）= 0.55，r（MA）= 0.39，P <0.01）。在青春期男孩中，这种相关性不显著，两组之间的斜率存在显著差异（P = 0.025）。青春期前男孩自发体力活动支出与训练活动支出呈显著正相关（r（UA）= 0.72，r（MA）= 0.52，P <0.001）。在这里，短睡眠者具有较低的身体活动，并且强化训练是负补偿的，减少了自发的身体活动。在青春期前体力活动男孩中，每日总体力活动和自发体力活动与清醒时间和训练呈正相关，这表明儿童对体力活动的特定控制（J Pediatr 2008：153：640-5）
Objectives To determine physical activity in healthy boys and how physical activity relates to training and daily awake hoursStudy design In 66 boys (5 to 15 year) affiliated with an ice-hockey club, we measured total daily energy expenditure (TDEE, doubly-labeled water) and basal metabolic rate (ventilated-hood method). Physical activity energy expenditure for the whole day (DAEE), during training, and during spontaneous physical activity was measured by accelerometry and activity protocols. Univariate (UA) and multivariate (MA) correlation analysis was applied.Results Physical activity level, DAEE, and TDEE for prepubertal (2.0 and 2.2 Mcal/d) and pubertal (bone age >= 13 years; 1. and 2.8 Mcal/d) boys were matched to literature data from nornial boys of equal age. In prepubertal boys DAEE correlate positively with awake hours (r(UA) = 0.55, r(MA) = 0.39, P < .01). In pubertal boys this correlation was not significant, the slope between the 2 groups being significantly different (P = .025). In prepubertal boys spontaneous physical activity expenditure correlated significantly positively with training activity expenditure (r(UA) = 0.72, r(MA) = 0.52, P < .001).Conclusion Contrary to findings in adults, v.,here short sleepers had lower physical activity and intensive training was negatively compensated reducing spontaneous physical activity. in physically active prepubertal boys, total daily and sponta neous physical activity relate positively to awake hours and training, suggesting child-specific control of physical activity (J Pediatr 2008:153:640-5)
