NCT ID: NCT04712578 Phase: NA Status: COMPLETED Enrollment: 24 Completion: 2021-05-11
Conditions
Resistance Training, Caffeine, Dietary Supplements
Interventions
Caffeinated pre-workout supplement, Non-caffeinated pre-workout supplement, Placebo
Summary
This study is a randomized, double-blind, placebo-controlled crossover trial examining the effects of caffeinated and non-caffeinated pre-workout supplements on resistance exercise performance. Resistance-trained adults will be randomly assigned to complete three study conditions (caffeinated pre-workout, non-caffeinated pre-workout, and placebo) in one of the six possible condition orders. During each condition, participants will report to the laboratory for ingestion of the assigned beverage and subsequent muscular performance testing. Major performance outcomes will be force production variables from a mechanized squat device and maximal strength and muscular endurance on the bench press and leg press exercises.
Primary Outcome
Isometric Peak Force Production
