Effect of the supplementation of teacrine compared to caffeine in performance in crossfit practice
Abstract
Introduction: Teacrine has been used as a caffeine-like ergogenic. This supplement that has been placed on the market lately, still without consistent studies related to CrossFit and without description of possible side effects. Objective: to verify the effect of theacrine supplementation compared to caffeine on the performance of CrossFit practitioners. Materials and Methods: The study was experimental performed through a clinical trial, blinded. We recruited 16 CrossFit practitioners for at least 1 year with a frequency of 3 times a week, male, aged between 25 and 35 years completed. The volunteers were submitted to an exercise protocol that were three equal tests in the two sessions. Before starting each protocol, the participant was submitted to a screening questionnaire. The study was carried out in two sessions with an interval of seven days between them. In the first session, participants ingested one capsule of anhydrous caffeine (250 mg). In the second session, researchers ingested a teacrine capsule (200 mg). Both were orally ingested one hour before the beginning of the exercise session. Results: In the statistical analysis of caffeine compared to theacrine, there was no statistical difference. Discussion: Studies that used a blend of caffeine with teacrine or just theacrine had similar effects, such as improved energy, better mood and less fatigue in more resistant exercises. Conclusion: Teacrine had a similar effect to caffeine in CrossFit practitioners in relation to performance.
