高强度间歇训练和中等强度持续训练对成年超重肥胖人群血压影响的元分析

Effects of HIIT and MICT on blood pressure in overweight and/or obese adults:a meta-analysis

[目的]运动改善超重或肥胖人群的血压对心血管疾病的预防有重要意义.比较健康肥胖或超重成人采用高强度间歇训练(HIIT)和中等强度持续训练(MICT)对舒张压(DBP)和舒张压(SBP)的影响.[方法]通过检索PubMed、Cochrane、Web of Science与CNKI数据库,共纳入文献12篇.纳入文献中HIIT与MICT组总样本量均为151个.采用随机效应模型(Random-effects Model)进行Meta分析.[结果]HIIT vs.MICT对超重/肥胖成人DBP、SBP无显著差异;[18,35]岁的亚组MICT改善BDP效果显著性优于HIIT,间歇时间小于2 min的HIIT亚组HIIT效果显著性优于MICT.[结论]对健康超重或肥胖成人在改善血压方面HIIT是高效的运动方式;年龄和训练周期影响HIIT和MICT改善血压的效果,在年龄低于35岁的人群中,MICT改善DBP的效果优于HIIT,间歇时间小于2 min的HIIT训练方式改善DBP效果低于MICT.

[Objective]Exercise to improve blood pressure in overweight or obese people is significant for the prevention of cardiovascular disease.To investigate the effects of high-intensity intermittent training(HIIT)and moderate intensity continuous training(MICT)for healthy obesity or overweight adults on the improvement of diastolic blood pressure(DBP)and systolic blood pressure(SBP).[Method]PubMed,Cochrane,Web of Science and CNKI database were consulted in the literature,totally including 12 literature and the total sample size of HIIT and MICT is 151 and 151 literatures respectively.Meta-analysis was performed through using a random-effects model.[Result]There was no significant difference for HIIT vs.MICT in overweight/obese adult DBP.MICT in subgroup of 18 age<35 was better than HIIT in improvement of BDP effect,and the effect of MICT improving DBP was better than that of HIIT in subgroup of intensity<2 min.[Conclusion]For healthy overweight or obese adults,HIIT is an effective way to improve blood pressure;age and training cycle affect the effect of HIIT and MICT on improving blood pressure.Among people under 35 years of age,MICT is better than HIIT in improving DBP,while HIIT training with interval less than 2 min improves DBP less than MICT.
