Aerobic training does not affect serum C reactive protein in smokers

A growing body of literature suggests that cigarette smoking is associated with systemic inflammation. This study was aimed to estimate the effect of aerobic training on serum C reactive protein (CRP) in smokers. For this purpose, thirty non-trained adult smoker men matched for age (41.6 +/- 4.2), height (175 +/- 5.7), and BMI (31.37 +/- 4.3) were divided into exercise or control groups by randomly. Pre and post exercise program (3 months/3 sessions per week) blood samples were collected after overnight fast in order to determine serum CRP in two groups. Student’s t-tests for paired samples were performed to determine significance of changes in variables by exercise program. Aerobic program resulted in significant decrease in anthropometrical parameters such as body weight and body mass index in exercise group but not in control group. In contrast, we did not change in serum CRP by exercise training when compared to pre training. Based on these data, we can say aerobic exercise training has not anti-inflammatory properties in smokers, although measuring of CRP alone can not predict anti-inflammatory property of exercise training.
