Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 20 participants
• Study Classification: INTERVENTIONAL

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.

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.

Conditions

Carbohydrate; Caffeine

Study Groups

Carbohydrate mouth rinsing

Rinsing mineral water for 20 seconds

Group Type: EXPERIMENTAL

Carbohydrate mouth rinsing

Intervention Type: OTHER

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

caffeine gum

placebo gum chewing for 10 min

Group Type: EXPERIMENTAL

200 mg caffeine gum

Intervention Type: OTHER

Chewing caffeinated gum for 20 minutes
