Abstract

The design objective of research was to investigate comparison between the effects of sodium bicarbonate [NaHCO3] different loading in high intensity intermittent activity on fatigue parameters of soldger. 30 s soldger s acccomplishment wingate test in two situations: NaHCO3 [SB] consumption and placebo. The SB [0.3 g·kg-1 of body mass] or the placebo was ingested 60 min before the training in Solution 250ml . before and After wingate test, blood sample was collected. All parameters were compared using two-way repeated measures ANOVA, followed by Tukey post-hoc test , significantly level was set at 5%. The [La-] in wingate test after SB [17.93 ± 3.8 mmol·l-1] supplementation was significantly higher than placebo [La-] [15.67 ± 3.29 mmol·l-1] [P<0.05]. No difference was found between SB and placebo for hr number. In conclusion, NaHCO3 did improve performance in soldgers, with enhance the glycolytic source without alteration of fatigue index.
