Does Single or Combined Caffeine and Taurine Supplementation Improve Athletic and Cognitive Performance without Affecting Fatigue Level in Elite Boxers? A Double-Blind, Placebo-Controlled Study

Abstract: In previous studies, the effect of single or combined intake of caffeine (CAF) and taurine (TAU) on exercise performance was investigated. However, the potential synergistic effect on physical and cognitive performance after fatigue induced by anaerobic exercise is unknown. The effects of single and combination CAF and TAU supplementation on the Wingate test in elite male boxers and to evaluate balance, agility and cognitive performance after fatigue are being investigated for the first time in this study.

“…The rationale for caffeine use is that it prevents the brain from releasing inhibitory neurotransmitters like adenosine and dopamine, which is an excitable neurotransmitter. Caffeine’s antagonistic actions may cause the release of excitatory neurotransmitters including dopamine and norepinephrine, which may have ergogenic effects in the brain [ 7 ]. Accordingly, caffeine supplementation is thought to promote a more positive mood [ 39 , 40 ], increase alertness, and reduce feelings of fatigue [ 41 , 42 ].…”

“…It acts as a glutamate reuptake inhibitor in the hippocampus and functions as a competitive low-affinity glutamate receptor antagonist [ 46 , 76 ]. On the other hand, CAF intake inhibits adenosine receptors (types A1 and A 2A ) in the brain, increasing dopaminergic and cholinergic transmission [ 7 , 32 ]. Consequently, the combined intake of CAF*THE improved cognitive performance by improving athletes’ mental processes, decision-making abilities, focus, and strategic thinking, ultimately contributing significantly to shooting performance.…”

“…This suggests that improvements in lower body power, as measured by the Wingate test, might have the potential to translate into enhanced punching power for boxers. This might be the reason why many studies have measured Wingate performance among boxers [ 44 , 45 , 46 ].…”
