摘要
目的:对比8周高强度间歇运动和中等强度持续运动对儿童哮喘临床症状、运动能力和生活质量的影响。方法:41名哮喘患儿分为高强度间歇运动(HIE)组、中等强度持续运动(MCE)组和安静对照(RC)组,HIE组和MCE组分别进行8周HIE或MCE,RC组保持原有生活习惯。试验前后,测定患儿生活质量(QOL)、肺功能、功能性运动能力,以及有氧、无氧运动能力。通过哮喘日志记录日间和夜间症状、应急用药、运动情况和运动时的不良反应。结果:(1)MCE运动时间和能量消耗分别是HIE的6.7倍和3.1倍,HIE组和MCE组不良反应率分别为3.3%和3.8%;(2)试验后,HIE组和MCE组哮喘症状评分和应急用药评分均低于RC组(P<0.05),无症状天数高于RC组(P<0.05);(3)试验后,HIE组QOL问卷中各分项得分及总得分,O2max,MAP,PP,MP和6MWT后的步行距离增加(P<0.05),6MWT后HR,SBP,DBP和RPE降低(P<0.05),肺功能参数无显著性变化(P>0.05),MCE组除无氧运动能力外,其他指标的变化与HIE组基本一致,且2组间差异无统计学意义(P>0.05)。结论:高强度间歇运动具有与中等强度持续运动相同的哮喘患儿临床症状、运动能力和生活质量改善作用;由于HIE较MCE具有明显的时效性和刺激性,并可提高无氧运动能力,因此可作为哮喘患儿运动康复处方的有益补充。
Objective：To compare the effectiveness of 8-week high-intensity interval exercise and moderate-intensity continuous exercise on clinical symp-toms,exercise capacity and quality of life in children asthma. Methods：41 mild-to-moderate asthma children were randomly divided into high-intensity intervalexercise（HIE）group,moderate-intensity continuous exercise（MCE）group and rest control（RC）group,in which subjects of HIE group and MCE group per-formed a 8-week high-intensity interval exercise or moderate-intensity continuous exercise while those of RC group maintained their normal lifestyle. Before andafter the trial,quality of life（QOL）,pulmonary function,functional exercise capacity,aerobic and anaerobic exercise performance were determined. An asthmadiary was used to record daytime and nighttime asthma symptom,use of emergency medication,participation in physical activity and adverse reaction during ex-ercise. Results：（1）Exercise duration and energy expenditure of MCE was 6.7 and 3.1 times of HIE respectively;rate of adverse reaction was 3.3% and 3.8% inHIE and MCE group respectively;（2）Asthma symptom score and use of emergency medication score were lower while symptom-free days were higher in HIEand MCE groups compared with RC group（P〈0.05）after trail;（3）After experiment,each domain score and total score of QOL questionnaire,VO2 max,MAP,PP,MP and distances after 6MWT were increased（P〈0.05）,while HR,SBP,DBP and RPE after 6MWT reduced（P〈0.05）,pulmonary function had no signifi-cant change（P〉0.05）in HIE group compared with pre-test. Except anaerobic performance（PP and MP）,the change of other parameters in MCE were similar tothose of HIE,moreover,there was no significant difference between two groups（P〉0.05）. Conclusions：Both HIE and MCE,with safe and effective under propersupervision and monitoring,could improve clinical symptoms,QOL,exercise performance（except anaerobic performance）and reduce dosage of emergency med-ication for asthma control,whi
