Abstract :

Futsal is a high-intensity interval sport that improves athlete performance through the use of specialized training programs and the consumption of appropriate nutritional supplements. The present study aimed to compare the effects of interval training and beta-alanine supplementation on the physical fitness of futsal players. Forty people participated in this study. The subjects were randomly divided into two equal groups: high-intensity interval training with supplementation, and high-intensity interval training with placebo. Agility, aerobic power, and anaerobic power tests were administered to futsal players in the pre-test and post-test. The high-intensity interval training program consisted of 10 repetitions of one-minute running at 90% of maximum heart rate, with one minute of active rest (running or walking) between each run. Beta-alanine supplementation was 6 grams per day, taken 30 minutes before and immediately after exercise. One-way analysis of variance was used for between-group comparisons at a significance level of 0.05. The results showed that aerobic power improved in the high-intensity interval training and beta-alanine supplement group compared to the interval training and placebo group. Peak anaerobic power was improved in the high-intensity interval training and beta-alanine supplement group compared to the interval training and placebo group. A significant decrease in running speed was observed in the high-intensity interval training and beta-alanine supplement group compared to the interval training and placebo group. Therefore, using a high-intensity interval training program due to its time efficiency can lead to improved physical and motor performance. In addition, combining interval training with beta-alanine supplementation can be more effective in affecting physical fitness.
