The aim of the study was to compare the effects of plyometric
training using 30, 60, or 120 s of rest between sets on explosive
adaptations in young soccer players.Four groups of athletes
(age 10.4 ± 2.3 y; soccer experience 3.3 ± 1.5 y) were randomly
formed: control (CG; n = 15), plyometric training with 30 s
(G30; n = 13), 60 s (G60; n = 14), and 120 s (G120; n = 12) of
rest between training sets.
