This study is to investigate how stress hormone has an effect on athletic performance of triathlon players. In order to assess change in body fluid, electrolyte, and hormone, the participants were divided into excellent players and non-excellent players of changes in the level of eythrocyte hematocrit, plasma osmotic pressure, Na+, K+, norepinephrine, testosterone, and cortisol during the 30 minute-pre-event, post-swimming event, post-cycle event, post-marathon race, and restoration period were monitored. As a result, plasma osmotic pressure, stress hormone, blood norepinephrine, and cortisol levels increased significantly during the triathlon event and restoration period, and maintained significantly higher in non-excellent group than excellent group.
As mentioned above, excessive increase of body fluid and electrolyte during the triathlon event is thought to be due to falling sensitivity of reaction of kidney to target cells under the negative feedback of R-A-A system, and these may cause dehydration, exhaustion, radicular pain, muscle cramp, and edema during the triathlon event. In addition, increase in stress hormone during the triathlon event is seen as a hormone reaction to excessive physical activity, and it means decreasing restoration capacity to reduce and maintain the level at stable state, that is, normal level, which in turn may drive lower athletic performance of non-excellent players than their counterparts.
