Caffeinated Gum Softball Performance

Taiwan24 participantsStarted 2022-05-20

Plain-language summary

The purpose of this study was to investigate the effects of caffeinated chewing gum on female softball pitching and hitting performance. 24 trained female softball players (10 pitchers and 14 fielders) were divided into a caffeine chewing gum trial (CAF) or a placebo trial (PLA) in a single-blind, randomized, crossover experimental design. Two pieces of gum containing 100 mg of caffeine (CAF) or without caffeine (PLA) were chewed for 10 minutes and then spit out, followed by a 15-minute warm-up. The physical tests included grip strength and countermovement jump. The softball-specific tests included pitching (fast ball speed) or hitting (exit speed). The two trials were separated by seven days.
