The purpose of this study was to find out the difference of human environmental factors(physical fitness and stress hormone) between two weight loss methods in national boxing players. 8 male boxers in national team participated in this study. In the 1st weight loss period(WLP), boxers took rapid weight loss during short period by using fast and sauna. In 2nd WLP, boxers took weight loss 1.5 kg per week during 2 weeks and received the systematic physical/nutritional program. The change of physical fitness and stress hormone were measured before and after weight loss of each period. The results were as follows. First, pulmonary function, isometric strength(back strength, left grip strength), isotonic maximal strength(bench press), and isokinetic strength(trunk extension) showed significant decrease after 1st WLP. However in 2nd WLP, all factors of physical fitness showed a tendency to improve or maintain and no factors were significantly decreased. Second, in stress hormone, there was no significant difference before and after WLP. However, cortisol and DHEA at wake-up time and cortisol at 11am showed a tendency to increase in 1st WLP. In conclusion, unscientific weight loss can cause problems in the conditioning of the boxing players. Therefore elite boxing players need a scientific weight loss method and systematic training program during WLP to maintain optimal conditioning.
