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. </span></p><p><span class="fontstyle0"><strong>Methods</strong>: </span><span class="fontstyle2">Forty‑seven male aged 40–60 years voluntarily participated<br />in this study and were divided in four groups: aerobic (</span><span class="fontstyle3">n </span><span class="fontstyle2">= 12), strength (</span><span class="fontstyle3">n </span><span class="fontstyle2">= 12), combined (</span><span class="fontstyle3">n </span><span class="fontstyle2">= 11), and control (</span><span class="fontstyle3">n </span><span class="fontstyle2">= 12) groups randomly. Body composition, ICAM‑1, VCAM‑1, and CRP were measured before and after 12 weeks. Data were analyzed using paired </span><span class="fontstyle3">t</span><span class="fontstyle2">‑test and analysis of variance<br />statistical methods. </span></p><p><span class="fontstyle0"><strong>Results</strong>: </span><span class="fontstyle2">There were signifcant differences in body weight between aerobic and strength training (</span><span class="fontstyle3">P </span><span class="fontstyle2">= 0.004) and aerobic and control groups (</span><span class="fontstyle3">P </span><span class="fontstyle2">= 0.018), body mass index between combined and strength training (</span><span class="fontstyle3">P </span><span class="fontstyle2">= 0.004) and combined and control groups (</span><span class="fontstyle3">P </span><span class="fontstyle2">= 0.001), fat percentage between aerobic training and control group (</span><span class="fontstyle3">P </span><span class="fontstyle2">= 0.017) and combined training and control groups (</span><span class="fontstyle3">P </span><span class="fontstyle2">= 0.004), and fnally, fat‑free mass between aerobic and strength training (</span><span class="fontstyle3">P </span><span class="fontstyle2">= 0.024),<br />aerobic and combined training (</span><span class="fontstyle3">P </span><span class="fontstyle2">= 0.0001), strength and control groups (</span><span class="fontstyle3">P </span><span class="fontstyle2">= 0.035), and combined and control groups (</span><span class="fontstyle3">P </span><span class="fontstyle2">= 0.0001).</span></p><p><strong></strong><span class="fontstyle0"><strong>Conclusions</strong>: </span><span class="fontstyle2">The results indicated that 12‑week workout, 20–60 min/session, 3 days a week of moderate intensity exercise improved body composition,<br />ICAM‑1, VCAM‑1, and CRP compared to those who did not participate in any training. However, all three types of exercises had small benefts on body composition, ICAM‑1, VCAM‑1, and CRP in sedentary middle‑aged men, and the importance of combined training required further investigations.<br /></span></p><p><span class="fontstyle0" style="color: #00652e;"><strong>Keywords</strong>: </span><span class="fontstyle3">Body composition, cardiovascular risk factors, exercise training, middle‑aged men</span> </p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/1876http://ijpm.mui.ac.ir/index.php/ijpm/article/download/1876/2158
