To examine the effectiveness of high-intensity aerobic training compared with low-intensity training in terms of energy cost of locomotion, peak oxygen uptake, peak power, and self-reported physical function in children with juvenile idiopathic arthritis (JIA).
Eighty children with JIA, ages 8-16 years, were enrolled in a randomized, single-blind controlled trial. Both groups participated in a 12-week, 3-times-weekly training program consisting of high-intensity aerobics in the experimental group and qigong in the control group. Subjects underwent exercise testing measuring submaximal oxygen uptake at 3 km/hour (VO(2submax)) as the primary outcome, maximal oxygen uptake, and peak power at the beginning and end of the program. Physical function was measured using the Child Health Assessment Questionnaire (C-HAQ).
The exercise program was well tolerated in both groups. There was no difference in VO(2submax) or any other exercise testing measures between the groups through the study period and no indication of improvement. Both groups showed significant improvements in C-HAQ with no difference between the groups. Adherence was higher in the control group than the experimental group.
Our findings suggest that activity programs with or without an aerobic training component are safe and may result in an important improvement in physical function. The intensity of aerobic training did not seem to provide any additional benefits, but higher adherence in the qigong program may suggest that less intensive regimens are easier for children with JIA to comply with, and provide a degree of benefit equivalent to more intensive programs.
比较高强度有氧运动训练与低强度训练对幼年特发性关节炎（JIA）患儿运动能量消耗、峰值摄氧量、峰值功率和自我报告的身体功能的影响。
80名年龄在8至16岁的JIA患儿参加了一项随机单盲对照试验。两组均参加为期12周、每周3次的训练计划，实验组进行高强度有氧运动，对照组进行气功练习。受试者在项目开始和结束时接受运动测试，测量3公里/小时的次最大摄氧量（VO₂submax）作为主要结果，以及最大摄氧量和峰值功率。使用儿童健康评估问卷（C-HAQ）测量身体功能。
两组对运动计划的耐受性良好。在整个研究期间，两组之间的VO₂submax或任何其他运动测试指标均无差异，也没有改善的迹象。两组的C-HAQ均有显著改善，组间无差异。对照组的依从性高于实验组。
我们的研究结果表明，有或没有有氧运动成分的活动计划都是安全的，并且可能会使身体功能得到重要改善。有氧运动训练的强度似乎没有提供任何额外的益处，但气功计划中较高的依从性可能表明，强度较低的方案对JIA患儿来说更容易遵守，并且能提供与强度较高的方案相当的益处。
