Journal Title: Journal of Combat Sports and Martial Arts - Year 2010, Vol 1, Issue 2
Abstract
[b]Introduction.[/b] The purpose of this study was to detect symptoms of adaptation to endurance and maximal, exhausting exercises attained after short-lasting training period at mild altitude in elite professional boxer. The state of adaptation was determined based on end-exercise blood hormones and lactate levels.[b]Material and methods. [/b]Professional boxer was examined at the end of 2-month detraining period. He underwent incremental exhaustive test (IET) on motorized treadmill, and two weeks after that examination he started training at mild altitude (1000 m). Four days after arrival to training camp located on 1000 m above see level he was subjected to the first trial opening the series of five exertions undergone on separated days. These exertions were separated by 3-day intermissions and were undergone in the order as follows: two repeated runs (2 x 400 m) with 30 second intermission between bouts, uphill running and walking (URW) with voluntary speed on a tourist trail which elevation was of 960 m (start at 1000 m, end at 1960 m above sea level) with distance to cover of 5.5 km (1st examination), resistance training session, repeated three runs (3 x 400 m) with 30 s intermissions and finally URW on the same trail as previously (2nd examination). These exercises were undergone at the same daytime (9:30-12:00 am) Capillary blood were sampled before and after laboratory test and field trials to measure levels of serum cortisol, testosterone, growth hormone, prolactin and blood lactate.[b]Results.[/b] The main symptoms of adaptation developing during training period were lower cortisol and prolactin responses to exertion occurring with time of training period.[b]Conclusions.[/b] The observed changes of post-exercise blood indices indicated rapid improvement of physical adaptation to the exertions following short-lasting training period.
