Conclusions
The present study showed that a low dose of CAF combined with listening to preferred music during warm-up improved physical-specific performances and psychological state in elite taekwondo athletes and reduced their perceived exertion better than their use separately. Moreover, for highly trained athletes, combining CAF and warm-up music serves to extend their effects during repeated high-intensity specific exercises as indicated using the FSKT-mult. Furthermore, the improvement recorded through the combination between low dose of CAF consumption and the use of musical stimulus during warm-up was not accompanied by significant side effects, indicating such a strategy to be safe and efficient.
