Plyometric training and beta-alanine supplementation are common among soccer players, although its
combined use had never been tested. Therefore, a randomized, double-blind, placebo-controlled trial was conducted to
compare the effects of a plyometric training program, with or without beta-alanine supplementation, on maximalintensity
and endurance performance in female soccer players during an in-season training period. Athletes (23.7 ± 2.4
years) were assigned to either a plyometric training group receiving a placebo (PLACEBO, n = 8), a plyometric
training group receiving beta-alanine supplementation (BA, n = 8), or a control group receiving placebo without
following a plyometric training program (CONTROL, n = 9). Athletes were evaluated for single and repeated jumps
and sprints, endurance, and change-of-direction speed performance before and after the intervention. Both plyometric
training groups improved in explosive jumping (ES = 0.27 to 1.0), sprinting (ES = 0.31 to 0.78), repeated sprinting
(ES = 0.39 to 0.91), 60 s repeated jumping (ES = 0.32 to 0.45), endurance (ES = 0.35 to 0.37), and change-of-direction
speed performance (ES = 0.36 to 0.58), whereas no significant changes were observed for the CONTROL group.
Nevertheless, compared to the CONTROL group, only the BA group showed greater improvements in endurance,
repeated sprinting and repeated jumping performances. It was concluded that beta-alanine supplementation during
plyometric training may add further adaptive changes related to endurance, repeated sprinting and jumping ability. [--]
