由于呼吸限制和健康状况的波动，囊性纤维化(CF)儿童很难在提高体能的强度下进行运动处方。我们的目的是使用儿童全方位量表得出的感知劳累(RPE)目标等级来确定患有CF的儿童是否能够调节自行车功率计和跑步机运动的强度。我们检查了处方的一致性(目标RPE的相似的氧耗量[VO2]和心率[HR])和强度辨别(不同的RPE的不同的VO2和HR)，从周期到周期和周期到跑步机。受试者为24名儿童(男12名，女12名)，年龄10-17岁，病情严重程度不一。每个孩子参加了一次定向试验、一次估计试验(分级最大运动试验)和两次生产试验(循环和跑步机，在RPE 4和7之间交替)。在RPE 4时，跑步机上的VO2和HR都明显一致。在RPE 4的循环中，VO2只在第一次生产试验中显著高于第一次生产试验，尽管在生产试验中HR往往高于估计试验。RPE 7也支持处方一致性，在自行车或跑步机上的估计试验和生产试验之间，VO2或HR没有显著差异。结果完全支持强度歧视，在RPE4和7时，VO2和HR之间存在显著差异(P<； 0.0001)。患有CF的儿童似乎能够使用OMNI量表来调节周期和跑步机运动强度。使用这种方法的训练有可能促进患有不同严重程度的CF儿童的健康。儿科肺单醇。2013；48：497-505。©2012 Wiley期刊，Inc.
Prescribing exercise at intensities that improve fitness is difficult in children with cystic fibrosis (CF) due to ventilatory limitations and fluctuating health status. Our aim was to determine if children with CF could regulate the intensity of cycle ergometer and treadmill exercise using target ratings of perceived exertion (RPE) derived from the Children's OMNI Scale. We examined prescription congruence (similar oxygen consumption [VO2] and heart rate [HR] for target RPE) and intensity discrimination (different VO2and HR for different RPEs), from cycle to cycle and cycle to treadmill. Subjects were 24 children (12 male, 12 female), aged 10–17 years with varying disease severity. Each child participated in one orientation, one estimation trial (graded maximal exercise test), and two production trials (cycle and treadmill, alternating between RPE 4 and 7). At RPE 4, congruence was evident for both VO2and HR on the treadmill. On the cycle at RPE 4, VO2was significantly higher only in the first production trial, although HRs tended to be higher in the production trials than the estimation trial. Prescription congruence was also supported at RPE 7, with no significant differences in VO2or HR between estimation and production trials on cycle or treadmill. Results fully supported intensity discrimination, with significant differences between VO2and HR at RPE 4 and 7 (P< 0.0001). Children with CF appear capable of using the OMNI Scale to regulate cycle and treadmill exercise intensity. Training using this methodology has the potential to promote fitness in children with CF of varying severity. Pediatr Pulmonol. 2013; 48:497–505. © 2012 Wiley Periodicals, Inc.
