Effects Of Caffeine, Beetroot Juice And Its Interaction Consumption On Exercise-Related Fatigue

The aim of this study was to analyze the effect different supplementation conditions on fatigue and performance in flywheel half-squat tests senior men. Sixteen active males (age: 22.8±4.9 years; body mass index: 23.7±2.4 kgm-2) participated intervention during a 4-week period. Four experimental were established using double-blind design: placebo, caffeine (CAF), beetroot juice (BRJ), combined BRJ+CAF. To assess supplementation, participants completed countermovement jump (CMJ) before (Pre), 30 s after (Post-30s) 180 (Post-180 s) completing exercise protocol (four sets eight all-out repetitions, with 3-min inter-set rest, inertial loads). Additionally, mean power output recorded. Repeated measured ANOVA showed greater (~1000 W, p<.001) produced/OR/generated CAF, BRJ BRJ+CAF consumption compared placebo condition. After CAF BRJ, CMJ at Post-180 reduced Pre (p=.003-.087, two-way ANOVA; ES=-0.39/-0.49), although no significant reduction (p=.087) noted In conclusion, allow total test, without effects exercise-related fatigue. improved recovery high demanding power-production protocol.
