对训练组（TG，N = 10）和对照组（CG，N = 13）的儿童进行了代谢和知觉反应的研究。在训练前，评估有氧功率（VO（2）峰值），儿童在分级功率输出下进行次极量运动。使用呼吸交换率（RER）和代谢率计算每个水平的底物使用量，并获得感知用力（RPE）评级以估计感知努力。训练包括12个阶段（每周3次，每次10分钟，50%VO（2）峰值）。4周后，以相同的绝对强度重新评估RER和RPE。总体差异评分表明TG中RER和RPE降低，CG中RER增加，RPE无变化。这些数据表明，儿童的短期周期训练导致脂肪使用增加，并减少了次极量运动期间的努力感。
Metabolic and perceptual responses to cycle training were investigated in children in a training group (TG, N = 10) and control group (CG, N = 13). Prior to training, aerobic power (VO(2)peak) was assessed, and children performed submaximal exercise at graded power outputs. Substrate use was calculated for each level using the respiratory exchange ratio (RER) and metabolic rate, and ratings of perceived exertion (RPE) were obtained to estimate perceptual effort. Training consisted of 12 sessions (three 10-min work bouts 3 times/week, 50% VO(2)peak) on a cycle ergometer. After 4 weeks, RER and RPE were reevaluated at the same absolute intensities. Overall difference scores indicated a decrease in RER and RPE in the TG and an increase in RER with no change in RPE in the CG. These data demonstrate that short-term cycle training in children results in enhanced fat use and diminished perception of effort during submaximal exercise.
