Fatigue is a condition that may affect physical performance during training sessions. Consequently, this will impact training performance and will also affect the performance of the individual in the long term. Caffeine is extensively used to counteract fatigue; however, it contains several side effects. Theacrine might be used as an alternative to caffeine, providing the same benefits without the side effects. The current study aimed to investigate the effects of 8 weeks of supplementation with theacrine on physical performance and training status of young amateur athletes. Twenty-two subjects were divided into two groups – Theacrine Group (T) and Placebo Group (P) – and evaluated before and after the intervention period. Evaluations included physical tests and hormonal values of insulin like growth factor (IGF)-I and IGF binding protein (IGFBP)-3, used as markers of training status. Results demonstrated that theacrine was not capable of promoting benefits regarding the physical performance of the subjects. It also had no effects on serum secretion of IGF-I and its binding protein, IGFBP-3. Therefore, the findings of this study do not support the use of theacrine to increase physical performance.
