From: Changes of direction during high-intensity intermittent runs: neuromuscular and metabolic responses
Changes in oxygen uptake ( V O 2 expressed as a percentage of maximal oxygen uptake), vastus lateralis (Hbdiff VL) and biceps femoris deoxygenation (Hbdiff BF), changes in blood lactate concentration (Δ[La] b ), rating of perceived exertion (RPE), drop jump (DJ) and countermovement jumping (CMJ) heights and EMG amplitude (RMS) in 8 muscles during and after high-intensity intermittent efforts (HIE), with (COD) or without (i.e., straight-line, SL) changes of direction. AL: adductor longus; VL: vastus lateralis; VM: vastus medialis; ST: musculus semitendinosus; BF: biceps femoris; MG: medial gastrocnemius; LG: lateral gastrocnemius; GL: gluteus medius; n = 11.
