ABSTRACT The aim of the study was to compare isokinetic performance (PT) of knee extensors (ext) and flexors (flex), H:Q ratio, and PT asymmetry in young soccer players based on somatic maturation. 80 soccer players (aged 12-17) were sampled, classified as pre-PHV (n=19) and post-PHV (n=61). Isokinetic dynamometry assessed knee extensors/flexors at 60º/s. Pre-PHV had lower body mass/height than post-PHV (P 15%, and cutoff points for each limb H:Q were set at ≥60%. Study showed increased isokinetic performance according to PHV, but no effect on asymmetries and H:Q ratio.
