To investigate the ability of children to improve aerobic fitness, as indicated by changes in maximaal oxygen uptake (VO2max), after a 12-week period of endurance training.
Longitudinal prospective training with control period.
Middle school physical education class.
Twenty-four girls and 13 boys, ages 10.9 to 12.8 years.
Three 30-minute sessions of aerobic activity weekly for 12 weeks at an intensity-producing a mean heart rate of 166 beats per minute. Maximal treadmill testing was performed 12 weeks before the training program and again at the start and end because each child served as his/her own control.
Mean VO2max did not change significantly during the control period but rose from 44.7 (5.8) to 47.6 (6.4) mL kg-1min-1 (6.5%) with training (P < .05). No differences in training response were observed relative to sex, pretraining VO2max, or sports participation.
These findings support the concept that VO2max can be improved with endurance training during the childhood years, but the degree of aerobic train-ability is limited in healthy, active children.
通过12周耐力训练后最大摄氧量（VO2max）的变化，研究儿童提高有氧适能的能力。
有对照期的纵向前瞻性训练。
中学体育课。
24名女孩和13名男孩，年龄10.9至12.8岁。
每周进行三次30分钟的有氧运动，共12周，运动强度使平均心率达到每分钟166次。在训练计划开始前12周、开始时和结束时分别进行最大跑步机测试，因为每个孩子都作为自己的对照。
在对照期，平均VO2max无显著变化，但经过训练后从44.7（5.8）升至47.6（6.4）毫升·千克-1·分钟-1（增长6.5%）（P <.05）。在训练反应方面，未观察到性别、训练前VO2max或体育活动参与情况的差异。
这些发现支持以下观点，即在童年时期，耐力训练可提高VO2max，但健康、活跃儿童的有氧训练能力程度有限。
