Carbohydrate Rinsing and Caffeine Gum on Performance of Romanian Deadlifts Performance

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.

Inclusion criteria

• regular weight training habits,
• familiarity with Romanian deadlift movements
• no chronic diseases such as hypertension, diabetes, and kidney disease or sports injuries such as lacerated knee ligaments, inflammation and rupture of tendons, strained biceps femoris or quadriceps, and strained biceps within the 6 months prior.

Exclusion criteria

• did not have regular exercise habits,
• were unfamiliar with Romanian deadlift movements
• had certain health problems that prevented them from performing exercise or injury from which they had not recovered for more than 6 months were excluded.
