dc.description.abstractPurpose: The highest work-rate that provides maximal oxygen uptake ((Formula presented.)) may be one of the best exercise stimuli to yield both (Formula presented.) and lactate accumulation. The aim of this study was to analyze physiological and metabolic acute responses of an exercise modality performed at the upper boundary of the severe exercise domain, and compare those responses with exercise modalities applied within the severe exercise domain. Method: Ten trained male cyclists participated in this study. The (Formula presented.), corresponding power output (PO<inf>VO2max</inf>), and the highest work-rate that provides the (Formula presented.) (I<inf>HIGH</inf>) were determined by constant work-rate exercises. Cyclists performed three high-intensity interval training (HIIT) strategies as follows; HIIT-1: 4–6 × 3-min at 95% of PO<inf>VO2max</inf> with 1:1 (workout/rest ratio); HIIT-2: 16–18 × 1-min at 105% of PO<inf>VO2max</inf> with 1:1; HIIT-3: 4–7 × 1-2-min at the I<inf>HIGH</inf> with 1:2. Capillary blood samples were analyzed before, immediately after HIIT sessions, and at the first, third, and fifth minutes of recovery periods. Lactate difference between the highest lactate response and resting status was considered as the peak lactate response for each HIIT modality. Results: Time spent at (Formula presented.) was greater at HIIT-1 and HIIT-3 (272 ± 127 and 208 ± 111 seconds, respectively; p = 0.155; effect size = 0.43) when compared to the HIIT-2 (~26 seconds; p < 0.001), while there was a greater lactate accumulation at HIIT-3 (~16 mmol·L?1) when compared to HIIT-1 and HIIT-2 (12 and 14 mmol·L?1, respectively; p < 0.001). Conclusions: In conclusion, HIIT-3 performed at I<inf>HIGH</inf> was successful to provide time spent at (Formula presented.) with a greater lactate accumulation in a single session. © 2022 SHAPE America.
