performance of young soccer players. J Strength Cond Res
29(5): 1317–1328, 2015—The aim of the study was to compare the effects of bilateral, unilateral, or combined bilateral
and unilateral plyometric training (PT) on muscle power output,
endurance, and balance performance adaptations in young soccer players. Four groups of young soccer players (age 11.4 6
2.2 years) were divided into control group (CG; n = 14),
bilateral group (BG; n = 12), unilateral group (UG; n = 16),
and bilateral + unilateral group (B + UG; n = 12). Players were
measured in unilateral and bilateral countermovement jump with
arms, 5 multiple bounds test, 20-cm drop jump reactive strength
index, maximal kicking velocity, sprint and agility test time, endurance, and balance performance. The PT was applied during 6
weeks, 2 sessions per week, for a total of 2,160 jumps. After
intervention, all PT groups showed a statistically significant (p #
0.05) change in all performance measures, with no statistically
significant differences between treatments. Among the 21 performance measures, the B + UG showed a significantly (p #
0.05) higher performance change in 13 of them vs. the CG,
whereas the UG and BG showed only 6 and 3, respectively.
The current study showed that bilateral, unilateral, and combined
bilateral and unilateral PT ensured significant improvement in
several muscular power and endurance performance measures
in young soccer players. However, the combination of unilateral
and bilateral drills seems more advantageous to induce superior
performance improvements.
