Abstract:
Objective:To investigate the effect of a 12-week circuit training program on health-related physical fitness and metabolic syndrome risk factors in obese female college students,and to provide reference for targeted interventions.
Methods:Sixty subjects with body mass index (BMI) over 28 kg/m2 were randomly allocated to control group ( n =30) or exercise group( n =30). Participants of control group maintained daily lifestyle while those of exercise group performed circuit training program 3 times per week for 12 weeks. Parameter of body composition (including back strength, sit-up, sit-and-reach, and 1 600 m running time), health-related physical fitness (including body height, body weight, BMI), percentage of body fat (PBF) and lean body mass (LBM) and metabolic syndrome risk factors [including waist circumference(WC), fasting blood glucose(FBG), triglyceride(TG), total cholesterol(TC), highdensity lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C)] were tested before and after the experiment.
Results:After intervention, body weight, BMI, PBF decreased, back strength, sit-up, sit-and-reach, and 1 600 m running time performance increased( t =2.14, 2.21, 2.48, -7.21, -7.69, -7.01, 4.83, P <0.05), WC, TG, TC reduced in exercise group compared with pre-test( t =2.89，4.54，2.71， P <0.05), whereas all parameters in control group showed no significantly different( P >0.05).
Conclusion:Regular circuit training improved body composition, enhanced physical fitness and may contribute to prevent metabolic diseases.
