Abstract:
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.
