Abstract/OtherAbstract:
While acute changes in systemic pro-/antiinflammatory cytokines occur with exercise, individual kinetics during and following exercise remain unclear; particularly, information is scarce regarding children. This study investigated the exercise-induced kinetic profiles of major pro-/anti-inflammatory mediators in 21 healthy children (13.9 +/- 0.8 yr, 7 M/14 F). Exercise was 30 min of intermittent cycling at approximately 80% VO2max. Multiple blood samples were drawn at baseline, during, and following exercise for cytokines assay. IL-1alpha, IL-6, IL-17, IL-8, IP-10, MIP-1alpha, and MIP-1beta initially decreased (nadir: 14-19 min into exercise) and subsequently exceeded baseline levels (peaks: 20-24 min into exercise). TNF-alpha, IL-12p70, IL-1RA, IL-4, EGF, TGF-alpha, GM-CSF, Eotaxin, and MCP-1 were moderately and persistently decreased throughout. VEGF was unchanged; sCD40L was elevated during exercise and recovery. Our results indicate that key immunomodulators display non-linear, biphasic kinetic profiles in response to exercise, suggesting that detection of exercise-induced changes over baseline may depend on exercise duration and sampling timing.
