Brief summary
Participants rinsed their mouths for 20 seconds with 25 ml of either 6.4% maltodextrin (CMR) or placebo (PLA). After rinsing, the grip force, counter-movement jump (CMJ) and batting tests were performed in sequence.
Detailed description
The purpose of this study was to investigate the effect of CMR on softball batting performance. Fourteen trained collegiate female softball players completed two trials in a randomization crossover trail, in which they rinsed their mouths for 20 seconds with 25 ml of either 6.4% maltodextrin (CMR) or placebo (PLA). After rinsing, the grip force, counter-movement jump (CMJ) and batting tests were performed in sequence. The tanner tee was utilised to perform five sets of five balls at a time, with a minimum of 3 minutes rest between sets. The batting test recorded average exit velocity, maximum exit velocity and batting accuracy. The standardized standard deviation (SD) for launch angle represents standardized variability.
