Figure 3

Changes in oxygen uptake ( V O 2, expressed as a percentage of maximal oxygen uptake), vastus lateralis (VL) and biceps femoris (BF) deoxygenation (Hbdiff), changes in blood lactate concentration (Δ[La] b ) and rating of perceived exertion (RPE) during and after each set of high-intensity intermittent efforts (HIE), with (COD) or without (i.e., straight-line, SL) changes of direction. VL: vastus lateralis muscle; BF: biceps femoris muscle; *: possible within-condition difference vs. Set1; ***: very likely within-condition difference; ****: most likely within-condition difference; n = 11.
