Background & Objective: The aim of the present study was to determine the effect of four-week high-intensity interval training with beta-alanine supplementation on aerobic and anaerobic performance and some blood parameters in girls basketball players.

Materials & Methods: This was a quasi-experimental study. Twenty female basketball players, with the mean age of 24.65 ± 4.81 years, height of 166.97 ± 4.12 cm, weight of 59.15 ± 5.23 kg and body mass index of 21.5 ± 1.23 kg/m2, were divided into two groups, including intervention (exercise + supplement) and control groups. Two days before and after the intervention, the subjects performed Wingate test (to estimate the average aerobic power) and Bruce test (to estimate VO2max).The subjects attended basketball training two sessions per week; Intervention group performed high-intensity interval training in addition to the basketball training in every session. The dose of beta-alanine supplementation was 2.4, 3.6, 4.8 g per day. After four weeks, creatine kinase and lactate levels and performance tests were reevaluated. Data were analyzed by SPSS software version 21, with a significance level of P<0.05.

Results: VO2max and anaerobic power increased significantly and fatigue index decreased significantly compared to the control group (p<0.05). But changes in the creatine kinase enzyme and lactate levels were not significant (p>0.05).

Conclusion: This study showed that high-intensity interval training with beta-alanine supplementation resulted in delay in the fatigue threshold, stabilization of PH and hydrogen ions balance, increased aerobic-anaerobic capacity and exercise performance in female basketball players.

Keywords: High-Intensity Interval Training, Beta-alanine, Aerobic and anaerobic capacity, Lactate, Creatine kinase
