Resumen
[EN] The aim of this study was to compare changes in young soccer player’s fitness after
traditional bilateral vs. unilateral combined plyometric and strength training. Male athletes
were randomly divided in two groups; both received the same training, including strength
training for knee extensors and flexors, in addition to horizontal plyometric training drills.
The only difference between groups was the mode of drills technique: unilateral (UG;
n = 9; age, 17.3 ± 1.1 years) vs. bilateral (TG; n = 9; age, 17.6 ± 0.5 years). One
repetition maximum bilateral strength of knee muscle extensors (1RM_KE) and flexors
(1RM_KF), change of direction ability (COD), horizontal and vertical jump ability with one
(unilateral) and two (bilateral) legs, and limb symmetry index were measured before and
after an 8-week in-season intervention period. Some regular soccer drills were replaced
by combination of plyometric and strength training drills. Magnitude-based inference
statistics were used for between-group and within-group comparisons. Beneficial effects
(p < 0.05) in 1RM_KE, COD, and several test of jumping performance were found in both
groups in comparison to pre-test values. The limb symmetry index was not affected
in either group. The beneficial changes in 1RM_KE (8.1%; p = 0.074) and 1RM_KF
(6.7%; p = 0.004), COD (3.1%; p = 0.149), and bilateral jump performance (from 2.7%
[p = 0.535] to 10.5% [p = 0.002]) were possible to most likely beneficial in the TG than
in the UG. However, unilateral jump performance measures achieved likely to most likely
beneficial changes in the UG compared to the TG (from 4.5% [p = 0.090] to 8.6%
[p = 0.018]). The improvements in jumping ability were specific to the type of jump
performed, with greater improvements in unilateral jump performance in the UG and
bilateral jump performance in the TG. Therefore, bilateral strength and plyometric training
should be complemented with unilateral drills, in order to maximize adaptations.
