Study Details

Study Description

Brief Summary

Two experiments were completed to investigate the effects of carbohydrate mouth rinsing and caffeine gum chewing on inertial resistance exercise performance. It was found that both carbohydrate gargling and caffeine gum chewing could improve inertial resistance exercise performance.

Condition or Disease	Intervention/Treatment	Phase
Carbohydrate Caffeine	Other: Carbohydrate mouth rinsing Other: 200 mg caffeine gum	N/A

Detailed Description

This study compared the effects of mouth rinsing with carbohydrates trial (CMR) or a placebo trial (PL) on inertial weight training performance with an inertial weight resistance device. The participants were recruited in this study. Participants were randomly allocated to the CMR and PL groups and subjected to a crossover experiment in which they performed maximum inertial resistance training comprising five sets of six reps, with 3-min rests between sets. After deducting the first repetition of each sets, the mean values from the five sets were analyzed.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Carbohydrate mouth rinsing Rinsing mineral water for 20 seconds	Other: Carbohydrate mouth rinsing the carbohydrate solution was prepared by dissolving 6.4 g of colorless and odorless maltodextrin in 93.6 mL of water; the mixtures were then adjusted to a 6.4% maltodextrin solution for the participants to rinse their mouths for 20 seconds
Experimental: caffeine gum placebo gum chewing for 10 min	Other: 200 mg caffeine gum Chewing caffeinated gum for 20 minutes
