Physiological responses to the first two sets of HIT for the team sport players with respect to the number of HIT sets completed before exhaustion.
| <3 sets | ≥5 sets | Standardized differences | Rating | Chances for greater/similar/lower values for the ≥5 group compared with the <3 group | |

Mean (SD) values for oxygen uptake (max), changes blood lactate accumulation (Δ[La]), changes in vastus lateralis (ΔVLHbdiff) and biceps femoris (ΔBFHbdiff) oxygenation, changes in drop (ΔDJ) and countermovement (ΔCMJ) jump height, and changes in muscle activity of the biceps femoris [ΔBFRMS] and medial gastrocnemius [ΔMGRMS] and rate of perceived exertion (RPE).
