| Abstract |
| Introduction: The aim of this study was investigete the effect of acute co-supplementation of beetroot juice (BJ) and caffeine (CAF) on Performance in elite male taekwondo athletes. Methods: Fourty-Eight professional taekwondo male athletes (Mean ± SD: Age 23.4 ± 2.8 yrs, Height 1.82 ± 0.05 cm, Weight 66.7 ± 8.5 kg, Body Mass Index 20.0 ± 1.7) volunteered. Height, body mass and body mass index (BMI) were assessed, and the Frequency Speed of Kick Test (FSKTmult). Participants completed five rounds of the FSKTmult. Participants consumed beetroot juice consentrate 70 mL (400 mg NO3−) and 3 mg.kg−1 of caffeine or placebo (PLA) along with rating of perceived exertion (RPE) in four groups. Results: CAF+BJ and CAF maintained higher kick frequency compared with PLA and BJ, particularly at rounds 2 and 5 (p < 0.05). PLA reported higher RPE compared with all supplement conditions (p < 0.05). For total number of kicks, CAF+BJ and CAF outperformed PLA (p < 0.001 and p = 0.006, respectively), and both exceeded BJ (p < 0.001). KFI was significantly lower in CAF compared with PLA (p = 0.015). Conclusion: Acute co-supplementation with caffeine and beetroot juice enhanced, increased repeated-sprint kick output, and reduced perceived exertion in taekwondo athletes, with effects superior to either supplement alone. |
