ResumoBACKGROUND: This study aimed to determine the energy contributions of alactic (PCr_w), glycolytic (GLY_w), and aerobic (AER_w) system during 6-second single sprint effort (6_SSE), 60-second single maximal exercise (60_SME), and 10×6-second repeated sprint exercise with 30-second rest intervals (10×6_RSE); and to compare performance and physiological responses.METHODS: Fourteen male kickboxers participated in this study. The estimated energy contributions of PCr_w, GLY_w, and AER_w were calculated based on oxygen uptake and lactate values. For 10×6_RSE, the estimated energy demand was calculated both for the entire protocol (10×6_RSE_overall) and for the sprints only (10×6_RSE_sprints).RESULTS: The main findings showed that total energy expenditure was higher in the 10×6_RSE than that in 6_SSE and 60_SME. The relative contributions of PCr_w, GLY_w, and AER_w were 57.2%, 38.4%, and %4.4 for 6_SSE; 43.1%, 12.8%, and 44.1% for 10×6_RSE_overall; 66.6%, 19.7%, and 13.6% for 10×6_RSE_sprints; and 27.8%, 43.6%, and 28.6% for 60_SME, respectively. Additionally, there was no significant difference between the 60_SME and 10×6_RSE in the calculated PCr payments during the fast phase of EPOC, while an average of 25.1 kJ PCr payments was observed during the rest intervals of the 10×6_RSE.CONCLUSIONS: Consequently, 10×6_RSE appears reasonable in monitoring the performance of combat athletes and using it as a training strategy.
