  Background: The purpose of the present study is to investigate the effect of one session of exhaustive activity with supplementation of beta-alanine on the level of carnosine and muscle strength of upper and lower extremities of bodybuilding athletes. Materials and Methods: Twenty bodybuilders were randomly divided into two equal groups of 10 who were taking supplemental beta-alanine and placebo. The experimental group consumed beta-alanine for 21 days and the placebo group received dextrose. The level of carnosine and muscle strength of the upper and lower extremities were measured before and after supplementation. Blood sampling was done before and after supplementation after session of exhaustive workout. Paired t-test and ANCOVA were used for data analysis using SPSS 21 software at a significant level (p <0.05). Results: The results of paired t-test showed that in all three variables of lactate, carnosine and growth hormone only in the beta-alanine group, a significant change was observed between pre-test and post-test (P <0.05). And amount of these variables in the post-test showed a significant difference compared to the pre-test. Also, ANCOVA test results indicated that there was a significant difference between the two groups of beta-alanine and placebo in all three variables (P <0.05). Conclusion: Beta-alanine supplementation with an exhaustive exercise session increases the level of carnosine in blood and hence increases the fatigue tolerance of bodybuilding athletes and ultimately improves the muscle strength of the upper and lower extremities of athletes and bodybuilders. Therefore, bodybuilders can use this supplement to improve their performance. Manuscript profile

  Background: The use of different kinds of dietary supplements is rising dramatically on a global scale these days. These substances include multifunctional performance-enhancing supplements, herbal supplements, and everyday vitamins. The main objective of this research is to find out how bodybuilding athletes' performance quality, muscle efficiency, and degree of satisfaction are affected by sports supplements. Materials and Methods: This study used a survey approach conducted in the field using a standardized questionnaire in conjunction with a descriptive-analytical research design. The study's statistical population included 131 participants who were among the top ten bodybuilding competitors at national championships. For statistical analysis, Friedman and linear regression tests were used after the data was collected. Results: The study results suggest that the majority of respondents concur that the use of sports supplements directly affects the functioning of body muscles. Moreover, the prolonged use of supplements that enhance weight and muscle volume has an increased effect on the performance of these athletes. The benefits of sports supplements are particularly noticeable throughout the second to fourth years of training for bodybuilding athletes as they continue to use these supplements. Conclusion: Evidence suggests that sports supplements have a discernible influence on muscle efficiency and the performance of bodybuilding athletes. Nevertheless, the use of sports supplements does not have a substantial impact on athlete satisfaction. Manuscript profile
