Abstract

This study aimed to determine the effects of acute caffeine ingestion on on-field performance in collegiate female field hockey players. A placebo-controlled, double-blind, randomized, crossover experimental design was utilized. The participants (N=10) were female division 1 field hockey players (age: 20.0 ± 1.6 years). They competed in two 60-minute, off-season scrimmages separated by two weeks. They were randomly assigned to ingest the caffeine, 3 mg/kg of body weight, or placebo treatment 60 minutes before each scrimmage. They wore a PLAYERTEK (Catapult, Australia) global positioning system (GPS) device to track their total distance, sprint distances, power plays, and zone three and above distance throughout the scrimmages. Other measures included rating of perceived exertion (RPE), rating of fatigue (ROF), and caffeine side effects. The GPS, RPE, and ROF data was analyzed using two-way within-subjects ANOVAs (time x condition), while side effect data were analyzed with Wilcoxon-Signed Rank testing. There was a significant increase in ROF over time during both scrimmages (p
