Turkey (Türkiye)13 participantsStarted 2023-09-24

Plain-language summary

Objective: To evaluate the effects of different caffeine mouth rinse concentrations (1%, 2%, and 3%) on Running Anaerobic Sprint Test (RAST) performance in female team-sport athletes. Main Questions: 1. Do caffeine mouth rinses improve RAST performance in female team-sport athletes? 2. Do different caffeine mouth rinse concentrations affect ratings of perceived exertion (RPE)? Method: Thirteen trained female football and handball players (23.0 ± 4.5 years) completed four randomized, double-blind, crossover conditions (1%, 2%, and 3% caffeine mouth rinses, and placebo). Each trial involved six 35 m sprints separated by 10 s of rest. RPE was recorded immediately after each session.
