Аннотация: The study examines fatigue in elite soccer played in hot conditions. High‐profile soccer players ( n =20) were studied during match play at ∼31 °C. Repeated sprint and jump performances were assessed in rested state and after a game and activity profile was examined. Additionally, heart rate (HR), blood lactate, muscle temperature and body mass changes were determined. Repeated sprint and jump performances were reduced ( P <0.05) by 2.6% and 8.2%, respectively, after the game. The fatigue index in the repeated sprint test was 6.0±0.7% after the game compared with 1.7±1.0% at rest ( P <0.05). High‐intensity running was 57±4% lower ( P <0.05) during the last 15‐min interval of the game compared with the first 15‐min period. No differences were observed in mean HR or blood lactates between halves. Muscle temperature was 40.5±0.4 °C after the first half, which was 0.8±0.2 °C higher ( P <0.05) than after the second half. Net fluid loss during the game was >2% of the body mass. Correlations were observed between net‐fluid loss and repeated sprint test fatigue index after the game ( r =0.73, P <0.05) and Yo‐Yo intermittent recovery, level 1 test performance and high‐intensity running during the final 15 min of the game ( r =0.51, P <0.05). The study provides direct evidence of compromised repeated sprint and jump performances induced by soccer match play and pronounced reduction in high‐intensity running toward the end of an elite game played in a hot environment. This fatigue could be associated training status and hyperthermia/dehydration.
