Abstract

This study investigated the predictors of aerobic fitness (VO2PEAK) in young children on a population-base. Participants were 436 children (229 boys and 207 girls) aged 6.7 ± 0.4 yrs. VO2PEAK was measured during a maximal treadmill exercise test. Physical activity was assessed by accelerometers. Total body fat and total fat free mass were estimated from skinfold measurements. Regression analyses indicated that significant predictors for VO2PEAK per kilogram body mass were total body fat, maximal heart rate, sex, and age. Physical activity explained an additional 4-7%. Further analyses showed the main contributing factors for absolute values of VO2PEAK were fat free mass, maximal heart rate, sex, and age. Physical activity explained an additional 3-6%.

摘要

本研究在人群基础上调查了幼儿有氧适能（峰值摄氧量）的预测因素。参与者为436名6.7±0.4岁的儿童（229名男孩和207名女孩）。在最大跑步机运动试验期间测量峰值摄氧量。通过加速度计评估身体活动。根据皮褶测量估计全身脂肪和去脂体重。回归分析表明，每千克体重峰值摄氧量的显著预测因素是全身脂肪、最大心率、性别和年龄。身体活动额外解释了4-7%的差异。进一步分析表明，峰值摄氧量绝对值的主要影响因素是去脂体重、最大心率、性别和年龄。身体活动额外解释了3-6%的差异。
