The main aim of this study was to determine the effect of sodium bicarbonate and beta-alanine supplementation on anaerobic capacity and blood lactate levels of female futsal players. 40 volunteer female futsal players of the Tehran League were selected based on the variables of entering the research and sampling and randomly selected four of the 40 volunteers and randomly divided into four control groups (n=10), sodium bicarbonate (n=10), beta-alanine (n=10) and sodium bicarbonate and beta-alanine (n=10) were divided. The anthropometric characteristics of their height, weight and body mass index were measured before the test. Then the Wingate test was performed to measure power and their blood lactate level was also measured using a lactometer. After each test session, the bicarbonate group received 0.3 grams of sodium bicarbonate supplement per kilogram of body weight, the beta-alanine group received 0.3 grams of beta-alanine supplement per kilogram of body weight, and the combined group also received per kilogram The combination of beta-alanine and sodium bicarbonate was used for 0.3 grams of body weight, and the control group used 0.3 grams of placebo (starch) per kilogram of body weight, and after 90 minutes, the relevant tests were performed again. Also, the subjects' diet was controlled during the test. Finally, descriptive statistics, Shapiro-Wilk test, one-way analysis of variance test and Tukey's post hoc test were used for statistical analysis of the data using spss/21 software at a significance level of p≤0.05. The results showed that the supplement of sodium bicarbonate and beta-alanine has a significant effect on the average power and blood lactate level of female futsal players. According to the results of the research, it is suggested that coaches and players use sodium bicarbonate and beta-alanine supplements to increase strength and reduce the negative effects of lactic acid.
