高强度间歇训练对超重肥胖女大学生减脂效果的Meta分析

  目的  系统评价高强度间歇训练(high-intensity interval training，HIIT)对超重肥胖女大学生体重、身体成分的干预效果，以期为超重肥胖大学生选择HIIT方法提供理论依据。  方法  计算机检索PubMed、the Cochrane Library、Web of Science、Embase、CNKI、CBM、VIP、WanFang Data数据库中有关HIIT对超重肥胖女大学生体重、身体成分的随机对照试验，检索期年限从各数据库收录起始年限至2020年12月14日，根据纳入和排除标准进行文献筛选，并对纳入文献进行方法学质量评价、Meta分析及发表偏倚检验。  结果  共纳入20个随机对照试验，中等质量研究14篇。Meta分析结果显示，HIIT能显著减轻超重肥胖女大学生体重(MD=-4.22，95%CI=-7.20~-1.25，P＜0.01)；改善体脂率(MD=-5.31，95%CI=-6.88~-3.73，P＜0.01)、体质量指数(BMI)(MD=-2.11，95%CI=-2.65~-1.56，P＜0.01)、全身脂肪量(MD=-3.66，95%CI=-4.89~-2.43，P＜0.01)、腹部脂肪量(MD=-0.31，95%CI=-0.47~-0.15，P＜0.01)、躯干脂肪量(MD=-2.15，95%CI=-2.86~-1.44，P＜0.01)，对瘦体重(MD=0.42，95%CI=-0.94~1.78，P=0.55)影响无统计学意义。  结论  HIIT能显著减轻超重和肥胖女大学生的体重，改善其身体成分，可为超重和肥胖女大学生进行长期的HIIT提供可靠依据。

Effects of high-intensity interval training on fat loss in overweight and obese female college students: a Meta-analysis

  Objective  To systematically evaluate the effectiveness of high-intensity interval training (HIIT) on body weight and body composition of overweight and obese female college students. In order to provide a theoretical basis for choosing HIIT method.  Methods  Randomized controlled trials (RCTs) published till December 14, 2020 were searched in PubMed, the Cochrane Library, Web of Science, Embase, CNKI, CBM, VIP and WanFang Databases. Literature screening was conducted based on inclusion and exclusion criteria, methodological quality evaluation, Meta-analysis and publication bias test were conducted on the included literature.  Results  There were 20 RCTs among which 14 studies graded as moderate quality. Meta-analysis showed that HIIT could significantly reduce the weight of overweight and obese female college students (MD=-4.22, 95%CI=-7.20--1.25, P < 0.01). Improved body fat rate (MD=-5.31, 95%CI=-6.88--3.73, P < 0.01), BMI (MD=-2.11, 95%CI=-2.65--1.56, P < 0.01), total body fat (MD=-3.66, 95%CI=-4.89--2.43, P < 0.01), abdominal fat (MD=-0.31, 95%CI=-0.47--0.15, P < 0.01), trunk fat (MD=-2.15, 95%CI=-2.86--1.44, P < 0.01) were observed. There was no significant effect on lean body weight (MD=0.42, 95%CI=-0.94-1.78, P=0.55).  Conclusion  HIIT can significantly reduce the weight and improve body composition in overweight and obese female college students. It can provide a reliable basis for long-term HIIT in overweight and obese female college students.
