Abstract
The aims of this study were (a) to investigate the effects of a unilateral training program, compared with a control group, on a force-velocity (F-V) profile in soccer players and (b) to explore such effects on linear speed. Twenty-four soccer players, randomly assigned to a 6-week unilateral strength and ballistic jump training (UNI) (n = 12) or a control group (CON) (n = 12), performed 30-meter linear sprint test. Findings showed small-to-moderate improvements (p < 0.05) in linear speed time (g = 0.66-0.81) and in most F-V variables: maximal running velocity (V0) (g = 0.81), maximal power output (Pmax) (g = 0.49), maximal ratio of force (RFmax) (g = 0.55), optimal velocity (Vopt) (g = 0.83), and maximal speed (g = 0.84) from pre- to post-intervention in the UNI group, whereas no meaningful changes were found in the CON group. The between-group comparison indicated small to large significant changes in V0 (g = 0.95), RFmax (g = 0.48), Vopt (g = 0.95), maximal speed (g = 0.98), and linear speed time performance (g = 0.42-1.02), with the exception of the 0-5 meter distance, in favor of the UNI group. Thus, a unilateral strength and ballistic jump training program can be used to improve the F-V profile and linear speed performance of amateur soccer players.
