摘要/Abstract

摘要： 目的：分析12周有氧运动（AE）和有氧运动结合抗阻训练（AE+RT）对肥胖男性大学生身体成分、心血管功能及血清C反应蛋白（CRP）的干预效果，为肥胖男性大学生运动处方的制定提供依据。方法：将36名肥胖男性大学生随机分为对照组、AE组和AE+RT组，每组12名。对照组肥胖男性大学生在整个试验期不进行任何规律的体育运动，AE组和AE＋RT组大学生进行每周5次、每次60 min共12周的运动干预。所有受试者在运动干预前和干预后检测体质量（BW）、体质量指数（BMI）、体脂肪量（FM）、体脂百分比（BF%）、肌肉质量（MM）、腰围（WC）和血清CRP水平，采用心血管功能测试仪评估心脏功能[心率（HR）、每搏心搏量（SV）和心输出量（CO）]、血管功能[平均收缩压（MSP）、平均舒张压（MDP）、血管弹性扩张系数（VDC）和总周阻阻力（TCR）]和血液黏度（V）。结果：与运动前比较，运动12周后AE组和AE＋RT组肥胖男性大学生BW、BMI、FM和BF%明显降低（P<0.05或P<0.01），AE＋RT组肥胖男性大学生MM明显增加（P<0.01），WC明显降低（P<0.01）。运动12周后，AE组和AE＋RT组肥胖男性大学生HR、MSP、TCR和V较运动前明显降低（P<0.05或P<0.01），SV和VDC明显增加（P<0.01）；AE组肥胖男性大学生运动前后MDP、CO和血清CRP水平均无明显改变（P>0.05），而AE＋RT组肥胖男性大学生运动12周后MDP和血清CRP水平较运动前明显降低（P<0.01），CO明显升高（P<0.01）。与AE组比较，AE＋RT组肥胖男性大学生运动12周后FM、BF%、HR、MSP、TCR和血清CRP水平均明显降低（P<0.05或P<0.01），MM、SV和CO均明显升高（P<0.05或P<0.01），WC、BMI、MDP、VDC和V差异无统计学意义（P>0.05）。结论： 12周AE和AE＋RT均可改善肥胖男性大学生的身体成分及心血管功能，且AE＋RT的效果优于单纯AE，但只有AE＋RT可降低血清CRP水平。

Abstract: Objective:To explore the intervention effects of aerobic exercise(AE) and AEcombined with resistance training(AE+RT) on the body composition, cardiovascular function and the serum C-reactive protein (CRP) level in the male obese college students, and to provide the evidence for exercise prescription in the male obese college students. Methods:A total of 36 male obese college students were chosen and randomly assigned into control group, AE group and AE+RT group(n=12). The students in AE and AE+RT groups conducted a 12-week (5 times per week and 60 min per time) exercise protocols and the students in control group did not perform regular physical training during 12 weeks of study. Then the body weight(BW),body mass index(BMI),fat mass(FM), percent of body fat(BF%), muscle mass(MM), waist circumference(WC) and the serum CRP levels of the subjects were measured before and after exercise;the cardiac function including heart rate(HR), stroke volume(SV) and cardiac output(CO), vascular function including mean systolic pressure(MSP), mean diastolic pressure(MDP), vascular elastic dilatation coefficient(VDC) and total cycle resistance(TCR) and blood status (V) were evaluated by cardiovascular function tester. Results:After 12-week training, BW, BMI, FM, and BF% of the students in AE and AE+RT groups were significantly decreased (P<0.05 or P<0.01) compared with before exercise, MM in AE+RT group was significantly increased(P<0.01) and WC was significantly decreased (P<0.01). After 12-week training, HR, MSP, TCR, and V in AE and AE+RT groups were significantly decreased (P<0.05 or P<0.01), SV and VDC were increased (P<0.05 or P<0.01); MDP,CO,and the serum CRP level in AE group had no significant differences between before and after exercise,and MDP and the serum CRP level after exercise in AE+RT group were significantly decreased (P<0.01), CO was increased (P<0.01) compared with before exercise. Compared with AE group, the FM, BF%, HR, MSP, TCR, and the serum CRP level of the students in AE+RT group after 12-week exercise were significantly decreased (P<0.05 or P<0.01); MM, SV, and CO were significantly increased (P<0.05 or P<0.01); but there were no significant differences (P>0.05) in WC, BMI, MDP, VDC, and V between AE and AE+RT groups. Conclusion:AE and AE+RT can improve the body composition and cardiovascular function of the male obese college students, and AE+RT is superior to single AE, while AE+RT can decrease the serum CRP level.
