Efeitos da suplementação de creatina na hipertrofia muscular em praticantes de musculação

Abstract

Creatine supplementation has been researched for their potential effect on the physical performance of athletes and bodybuilders, contributing muscle hypertrophy and reduced fatigue. Objective: To evaluate changes in body composition that involves the body fat percentage of bodybuilders supplemented with pure creatine monohydrate, creatine and biochemical changes of hemodynamic changes during the pre-and post-supplementation. Material and Methods: A total of 8 weeks (n = 21) bodybuilders, with aged (24.10 ± 2.88 years). Thus was analyzed weight, heart rate, blood pressure,double product, BMI, IAC, waist circumference, WHR, fat body percentage and creatinine. Results and Discussion: There was a significant reduction (p<0.01) in weight (p <0.05) and percentage fat (P <0.03) in heart rate, which may have been enhanced by the use of creatine. For the other parameters did not differ between groups. Conclusion: We can conclude that the results were satisfactory with a reduction in fat body percentage of the supplemented group, as well as satisfactory values regarding the biochemical and hemodynamic. However, further studies are needed to contribute to the academic and scientific community.
