PG - 288-292 LID - 10.1111/cpf.12299 [doi] AB - This study was designed to examine the relationships between body composition, cardiorespiratory fitness and simultaneously measured inflammatory parameters in endurance-trained athletes. In 20 well-trained rowers (19.0 +/- 2.9 years; 185.6 +/- 4.8 cm; 85.7 +/- 10.8 kg; 17.1 +/- 5.1% body fat; maximal oxygen consumption [VO(2) max]: 63.9 +/- 8.5 ml min(-1) kg(-1) ), body composition was measured by dual-energy X-ray absorptiometry and cardiorespiratory fitness by direct VO(2) max test. Twelve inflammatory factors [interleukin (IL)-2, IL-4, IL-6, IL-8, IL-10, vascular endothelial growth factor, interferon-gamma (IFN-gamma), tumour necrosis factor-alpha, IL-1alpha, IL-1beta, monocyte chemoattractant protein-1 (MCP-1), epidermal growth factor (EGF)] were analysed from serum samples. Serum IFN-gamma was related (P<0.05) to fat-free mass (FFM) (r = -0.56) and muscle mass (r = -0.50). The stepwise regression analysis showed that IFN-gamma explained 27.5%, and IFN-gamma and IL-6 together explained 39.8% of the variability of FFM, while IFN-gamma explained 21.1%, and IFN-gamma together with EGF explained 36.6% of the variability of muscle mass in male rowers. Serum IL-8 (r = -0.65) and VEGF (r = -0.48) correlated (P<0.05) with VO(2) max kg(-1) . Serum IL-8 explained 38.5% of the variability of VO(2) max kg(-1) . Significant correlations were also found among several inflammatory parameters, indicating that various inflammatory cytokines act on the body as an ensemble. In conclusion, this cross-sectional study in endurance-trained male rowers showed that FFM and muscle mass were negatively correlated with serum IFN-gamma level, whereas cardiorespiratory fitness was negatively related to serum IL-8 level.
