Abstract: The aim of the research was determine the influence of temperature on muscle metabolism ! and exercise performance time among elite athletes. The study was conducted in 10 high performance athlete's rowers participating in national level leagues. All the participants of the study performed load 70% VO2max intensity on ergometer Concept II before the withdrawal. Physical load was performed at 3°C (Z), 18°C (V) ir 30°C (A) environmental temperature. The biochemical parameters as lactate (La), creatine kinase (CK), epinefrine (E), ammonia (NH3) heart rate (HR) and performance time were estimated. The results showed that significant differences were obtained in E, La, and CK indices and performance time after performing in 30°C (A) environmental temperature (p <.05). There is a suggestion, that La and E concentration indices variations can be determined by stress to perform the load as long as possible. Increase in the concentration of NH3 3°C temperature after exercise may be due to AMP-deaminase activity have also placed by other authors ((Cheurount et al., 2001; Febbraio et al., 1996). Shorter working time in 30°C shows that the hot environment influenced on faster running out of energy. The study results show that high performance athletes (rowers) physical loads in a hot environment affects muscle metabolism and limits their activity
