循环训练对肥胖女大学生身体成分体适能和代谢综合征危险因素的影响

目的探讨12周循环训练对肥胖女大学生身体成分、体适能以及代谢综合征危险因素的影响,为针对肥胖女大学生相应干预措施的制定提供参考。方法将某高校60名肥胖女大学生随机分为对照组和运动组各30名。对照组保持日常生活习惯不变,运动组进行3次/周、共12周的循环训练。分别于干预前后测定身体成分[身高、体重、体质量指数(BMI)、体脂百分比(percentage of body fat,PBF)和瘦体重(lean body mass,LBM)]、健康体适能(背肌力量、仰卧起坐、坐位体前屈和1 600 m跑成绩)和代谢综合征危险因素[腰围(waist circumference,WC)、空腹血糖(fasting blood glucose,FBG)、三酰甘油(triglyceride,TG)、总胆固醇(total cholesterol,TC)、高密度脂蛋白胆固醇(high-density lipoprotein cholesterol,HDL-C)和低密度脂蛋白胆固醇(low-density lipoprotein cholesterol,LDL-C)]相关参数。结果与干预前比较,干预后运动组体重...

Effect of circuit training on body composition,physical fitness,and metabolic syndrome risk factors in obese female college students

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/m^2 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), high-density 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-andreach, 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.
