dc.description.abstractCaffeine increases vertical jump, although its effects on kinetics and kinematics during different phases of bilateral and unilateral jumps remain unclear. The aim of this study was to identify the effects of 3 mg/kg on kinetic, kinematic and temporal variables in the concentric and eccentric phases of bilateral and unilateral countermovement jumps. A total of 16 Spanish national team traditional Jiu-Jitsu athletes took part in two experimental trials (3 mg/kg caffeine or placebo) in a randomized, double-blind crossover study. Sixty minutes after ingestion, bilateral and unilateral jumps were performed on a force platform. Compared to the placebo, caffeine increased bilateral jump height (p = 0.008; D% = 4.40), flight time (p = 0.008; D% = 2.20), flight time:contraction time (p = 0.029; D% = 8.90), concentric impulse (p = 0.018; D% = 1.80), peak power (p = 0.049; D% = 2.50), RSI-modified (p = 0.011; D% = 11.50) and eccentric mean braking force (p = 0.045; D% = 4.00). Additionally, caffeine increased unilateral RSI-mod in both legs (Left: p = 0.034; D% = 7.65; Right: p = 0.004; D% = 11.83), left leg flight time (p = 0.044; D% = 1.91), left leg jump height (p = 0.039; D% = 3.75) and right leg FT:CT (p = 0.040; D% = 9.72). Caffeine in a dose of 3 mg/kg BM in elite Jiu- Jitsu athletes is a recommended ergogenic aid as it increased performance of bilateral and unilateral vertical jumps. These increases were also accompanied by modified jump execution during the different phases of the countermovement prior to
