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.
