Performance improvement is associated with higher postexercise responses in interleukin-6 and tumor necrosis factor concentrations.

摘要

AIM: The aim of this study was to investigate the postexercise concentrations in IL-6 and TNF-alpha during maximal 6000 meter time trial in conditions with improved performance capacity. METHODS: Nine highly trained male rowers (age 19.67+/-1.0; height 190.67+/-4.24 cm; weight 91.07+/-6.24 kg) participated. Subjects were asked for body composition measurement and two 6000 meter all-out rowing ergometer trial separated by one year. RESULTS: The 6000 meter rowing ergometer performance was significantly improved during one year period from from Test 1 to Test 2 (from 330.3+/-21.9 W to 349.2+/-20.3 W, P0.05) and no signigficant relationships between the measured body compositional and blood biochemical parameters. Postexercise changes in IL-6 concentration were significantly related to changes in performance (r=-0.667 and r=-0.865 for POST and POST 30, respectively; P<0.05). CONCLUSION: In conclusion improvements in performance resulted in higher postexercise concentrations of IL-6 and TNF-alpha in highly trained male rowers.
