Primary Outcome Measures

Name	Time	Method
o decrease in performance times in the Ironman event. A performance decrement of 10% or greater of elapsed time in the Ironman event which cannot be explained by any other means (wind, waves, cureents, punctures, injuries) is regarded as overtraining syndrome.[12 weeks];Performance decrease in time trials. These time trial consist of a 400m swim in a 50m heated outdoor pool, a 4 km run held on an enclosed, but open roofed running track, and a 20 km simulated time trial on a cycle ergometer using the Tacx System[0 weeks, 6 weeks and 12 weeks];Changes in blood concentrations of corticotrophic releasing hormone (CRH), adrenocorticitrophic releasing hormone (ACTH) and cortisol[0 weeks, 6 weeks, 12 weeks]

Secondary Outcome Measures

Name	Time	Method
o jump in day to day waking pulse of 5 beats per minute or more. Pulse is taken manually by the participant and counted for one full minute[The pulse is taken daily and any jump in waking heart rate from one day to the next of 5 beats per minute or more is regarded as indicative of overtraining syndrome. The pulse rate is therefore assessed over the entire 12 week period];Daily waking rectal temperature is taken and monitored. Temperature is taken by an Omron electronic digital thermometer. No mercury is involved[Daily for 12 weeks. Changes in core temperature is taken as evidence that the hypothalamic control of core temperature has been altered];Any changes in blood concentration of CRH, ACTH and cortisol will be correlated to performce decrements[0 weeks, 6 weeks, 12 weeks]
