In this study, the effects of sodium phosphate (SP) and beetroot juice (BJ) supplementation were assessed on repeated-sprint ability (RSA). Methods: Thirteen female team-sport participants completed four trials: (1) SP and BJ (SP+BJ), (2) SP and placebo (for BJ), (3) BJ and placebo (for SP) and (4) placebo (for SP+BJ), with ~21 days separating each trial. After each loading phase, participants performed a simulated team-game circuit (STGC) consisting of four 15 min quarters, with a 6 x 20-m repeated-sprint set performed at the start, half-time and end of the STGC. Results: Total sprint times were between 0.95-1.30 s and 0.83-1.12 s faster for each RSA set and 3.25 s and 3.12 s faster overall (~5% improvement) after SP compared with placebo and BJ (p=0.02, p=0.02, respectively; Cohen’s effect size (d)=-0.51 to -0.90 for all sets). Additionally, total sprint times were 0.48 s faster after SP+BJ compared with placebo (set 2; p=0.05, ~2% improvement). Furthermore, a main effect for trial (p
Results: Performance was significantly improved following caffeine administration in women (placebo: 4036±440s, caffeine: 3865±328s; p=0.03) and men (placebo: 3903±341s, caffeine: 3734±287; p
