Carbohydrate Rinsing and Caffeine Gum on Performance of Romanian Deadlifts Performance

Not Applicable

Completed

• Conditions: Carbohydrate; Caffeine

• Registration Number: NCT05900349
• Lead Sponsor: National Taiwan Sport University

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.
