Carbohydrate Mouth Rinsing and Softball Batting Performance

Carbohydrate Mouth Rinsing and Softball Batting Performance: a Double-blind Crossover Study

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.

Study Overview

• Status: Completed
• Conditions: Carbohydrate
• Intervention / Treatment: Dietary supplement: Exercise

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.
