OBJECTIVE
The purpose of this study was to evaluate the effects of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on cardiovascular disease (CVD) risk factors in adults with overweight and obesity.
METHODS
Twenty-two articles were included by searching six databases, the total number of subjects was 620 in these articles. Outcomes were synthesised using a random-effects meta-analysis of the Standardized mean difference (SMD) in CVD risk factors.
RESULTS
HIIT and MICT resulted in statistically significant reductions in Weight, BMI, fat%, total cholesterol(TC), and improvement in VO2max. Compared with MICT, subgroup of durations of HIIT training interval ≥2 min can significantly increase VO2max (SMD = 0.444, 95% CI:0.0370.851,P = 0.032), subgroup of energy expenditure of HIIT equal to MICT can significantly increase VO2max (SMD = 0.399, 95% CI:0.1060.692,P = 0.008).
CONCLUSIONS
HIIT appears to provide similar benefits to MICT for improving body composition, VO2maxand TC, but HIIT spent less time than MICT by 9.7 min on one session. HIIT is superior to MICT in improving cardiopulmonary fitness when durations of HIIT training interval ≥2 min or energy expenditure of HIIT same as MICT. PROSPERO ID: CRD42016045835.
目的
本研究旨在评估高强度间歇训练（HIIT）和中等强度持续训练（MICT）对超重和肥胖成年人心血管疾病（CVD）风险因素的影响。
方法
通过搜索六个数据库，共纳入 22 篇文章，这些文章的总样本量为 620 例。使用 CVD 风险因素的标准化均数差（SMD）的随机效应荟萃分析综合结果。
结果
HIIT 和 MICT 可显著降低体重、BMI、体脂%、总胆固醇（TC），并改善最大摄氧量（VO2max）。与 MICT 相比，HIIT 训练间歇持续时间≥2 分钟亚组可显著提高 VO2max（SMD = 0.444，95%CI：0.0370.851，P = 0.032），HIIT 能量消耗与 MICT 相等亚组可显著提高 VO2max（SMD = 0.399，95%CI：0.1060.692，P = 0.008）。
结论
HIIT 在改善身体成分、VO2max 和 TC 方面似乎与 MICT 提供相似的益处，但 HIIT 每节训练比 MICT 少 9.7 分钟。当 HIIT 训练间歇持续时间≥2 分钟或 HIIT 能量消耗与 MICT 相同时，HIIT 在改善心肺适能方面优于 MICT。PROSPERO 注册号：CRD42016045835。
