Abstract
Background and Objectives: Exercise and stressor environments could lead to some immune changes in human body. The aim of this study was to investigate the effect of exercise on the serum interleukin-17, interferon-γ and highly sensitive (HS) CRP of the Endurance athletes in cold temperature condition.
Materials and Methods: Ten young male endurance athletes (22±2years; 67.4±2.7kg) ran on a treadmill for 1h at %60 VO2max in conditions of normal (22±1˚c, 50±5 RH) and cold temperature (3±1˚c, 50±5 RH). The interleukin 17, interferon-γ, hs-CRP and cortisol concentrations were measured before, immediately after and two hours after exercise (during recovery). Body temperature, rating of perceived exertion and amounts of consummated water during exercise all was recorded. Data analysis was performed by statistical methods.
Results: There was no significant change in serum concentrations of interleukin 17, interferon-γ and hs-CRP athlete’s after and 2 h after exercise (p>0/05). There was no significant difference between this values in two environments (p>0/05). The amounts of cortisol increased significantly after exercise, in both normal and cold environment (p<0.0001).
Conclusion: A single session of exercise causes the circulatory release of cortisol. However, it seems that it cannot induce the alteration in inflammatory responses and increase cytokines and inflammatory markers.
