  • Descrição: BACKGROUND: High-Intensity Functional Training (HIFT) is nowadays widely used due to low time demand and efficiency to improve performance and health. The dynamics of recovery of muscle damage and physical fitness after a HIFT in individuals with different fitness status provide practical information for coaches and practitioners. Therefore, the aim of this study was to verify the muscle damage and performance recovery responses after an acute HIFT session in healthy young men with different fitness status. METHODS: Sixteen recreationally trained participants (age: 23.4 ± 2.4y; body mass index: 24.6 ± 2.4kg·m-2; one maximum repetition [1RM] back squat: 120.1 ± 19.9kg) were divided in two groups according to their maximum strength (higher-trained [HT] and lower-trained group [LT]) and performed a single HIFT session. Muscle damage (creatine kinase [CK] and lactate dehydrogenase [LDH]) and physical fitness tests (strength, power, and oxygen consumption) were analyzed before, immediately after, 24h and 48h after the HIFT session. The internal training load for both groups was equalized using the Rating of Perceived Exertion method (RPE) and the percentage 1RM. RESULTS: Biochemical markers showed that both groups suffered exercise-induced muscle damage, whereas performance (jump height in Countermovement Jump (CMJ), Relative Power in CMJ for both groups and VO2max for LT group) were affected immediately after exercise HIFT session. There was a tendency for faster muscle damage recovery in HT group. CONCLUSIONS: HT group showed higher muscle damage recovery compared with LT group. Longer recovery time might be expected to complete muscle recovery in LT group.
