摘要：Background:Previous studies have indicated that exercise training improves body composition and cardiovascular disease risk factors. The aim of the present study was to investigate the effect of 12 weeks of aerobic, strength and combined training on body composition, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and C-reactive protein (CRP) in sedentary middle-aged men.Methods:Forty-seven male aged 40–60 years voluntarily participated in this study and were divided in four groups: aerobic (n= 12), strength (n= 12), combined (n= 11), and control (n= 12) groups randomly. Body composition, ICAM-1, VCAM-1, and CRP were measured before and after 12 weeks. Data were analyzed using pairedt-test and analysis of variance statistical methods.Results:There were significant differences in body weight between aerobic and strength training (P= 0.004) and aerobic and control groups (P= 0.018), body mass index between combined and strength training (P= 0.004) and combined and control groups (P= 0.001), fat percentage between aerobic training and control group (P= 0.017) and combined training and control groups (P= 0.004), and finally, fat-free mass between aerobic and strength training (P= 0.024), aerobic and combined training (P= 0.0001), strength and control groups (P= 0.035), and combined and control groups (P= 0.0001).Conclusions:The results indicated that 12-week workout, 20–60 min/session, 3 days a week of moderate intensity exercise improved body composition, ICAM-1, VCAM-1, and CRP compared to those who did not participate in any training. However, all three types of exercises had small benefits on body composition, ICAM-1, VCAM-1, and CRP in sedentary middle-aged men, and the importance of combined training required further investigations.
