Abstract
Aim: Regular aerobic exercise may reduce cardiovascular disease (CVD) risk by lowering the concentration of inflammatory markers, such as C-reactive protein (CRP). While studies in diseased populations have shown significant decreases in CRP concentrations with regular aerobic training, little has been conclusively determined regarding the effects of aerobic training on CRP concentrations in apparently healthy, untrained populations. Aim of the study was to examine the effects of a 17-wk half marathon training program (TP) on CRP concentrations, aerobic fitness, and body composition in apparently healthy, untrained men. Methods: Twenty men (29.3±1.0 y) enrolled as training subjects (TRN) in a 17-wk half marathon TP. An additional 22 men (27.8±1.4 y) served as controls (CON). Fasting blood samples were taken at four time points over the TP and were analyzed for CRP and interleukin-6 (IL-6) concentrations. Aerobic capacity (VO 2max) and body fat percent (BF%) were measured before and after the TP. Results: No significant post-training changes in CRP (P=0.70) or IL-6 concentrations (P=0.67) were seen in TRN as a result of the TP, despite significant improvements in VO 2max (42.2±1.9 ml·kg -1.min -1, P<0.0001) and significant reductions in resting heart rate (P=0.004), BF% (P=0.03), and body mass index (BMI, P=0.05). No significant changes in CRP, VO 2max, BMI, or BF% were detected in CON over time. Conclusion: Regular aerobic training does not appear to affect CRP concentrations in apparently healthy, untrained men despite significant improvements in body weight, BF%, BMI, and VO 2max.
