| Abstract | |
The overall aim of this study was to investigate the ergogenic effect of 4 weeks β-alanine supplementation on the anaerobic power, ability to performed repeated efforts and performance of water polo. 22 male elite players (mean±SD age = 18±4 years, weight = 78.5±9.5 kg and height = 1.79±0.06 m) participated in the study, which was conducted in order randomized, double blind and placebo controlled. Participants were divided into two groups (β-alanine and placebo) of 11 athletes each and were subjected to specific tests (repeated sprint ability test (RSA) and maximum 30s jump under the goal test (30CJ)) and semi-specific (30s maximal test in tethered swimming (30TS), maximal 3 min effort (AllOut-3min), tethered swimming graded exercise test (GXTTS) and 200m in front crawl (P200m)) for the modality and a simulated game to enable tracking of the activities carried out by video record. Assessments occurred before and after the supplementation period (4 weeks). There were no significant interaction effects between the groups for any variable of this study. However, some slight improvement indications with β-alanine supplementation were found to: (1) significant improvement between moments (pre × post) the total number of sprints during the simulated game water polo; (2) probably beneficial effect (magnitude-based inference analysis) for the mean time, worst time and total time in the first series of the RSA test (RSA1); (3) significant improvement between moments for mean force and integral of force during the 30TS and P200m; (4) significant improvement between moments for peak power at GXTTS. Therefore, it is concluded that supplementation for 4 weeks of β-alanine can promote only slightly improve some parameters related to swimming ability in water polo as total number of sprints in simulated game, mean time, worst time and total time on test RSA, mean and integral of force in 30TS, P200m and critical force in GXTTS.
