The purpose of this study was to Comparison of effect Beta-Alanine and sodium bicarbonate supplementation on changes PH, blood lactate, anaerobic power and muscle damage indicators in elite men taekwondo.For this reason,20elite men taekwondo were selected as subjects and they divided into two groups randomly including Beta- Alanine supplementation(n=10) and sodium bicarbonate supplements(n=10) . Beta-Alanine supplementation within 6 weeks Taekwondo training three times a week with Beta-Alanine 3.2 gr per day (3 hours before exercise) consumption. sodium bicarbonate three times a week during 6 weeks practicing Taekwondo with 0/3 gr by weight of sodium bicarbonate (1 hour before the exercise) consumption. Blood sample were taken in before, and 24 hours after taekwondo for assessmentLDH and CK. analyzed using the paired t Test with independent t-test (P<0.05). Results showed that 6 weeks of supplementation with Beta-Alanine and sodium bicarbonate supplementation, there was no significant differents between there was no significant differents between lactate dehydrogenase in the group (P≥0 / 05). there was no significant differents between creatine kinase in the group (P≥0/05). The results showed that Taekwondo with Beta-Alanine and sodium bicarbonate supplementation to prevent an increase in lactate dehydrogenase, and creatine kinase. It seems that 3.2 gr per day beta-alanine supplementation with 0/3 sodium bicarbonate may be effectives in preventing fatigue and reduced muscle damage in athletes .
