Acute Caffeine Intake and Velocity Metrics

Summary

The purpose of this study was to determine whether the acute ergogenic effects of caffeine differ according to the velocity metric used to assess strength performance against different relative loads. Thirteen resistance-trained men completed a triple-blind, randomized, placebo-controlled, crossover study. Participants ingested either caffeine (3 mg·kg-1) or a placebo 60 min before performing bench press and back squat exercises at 25%, 50%, 75%, and 90% of one-repetition maximum (1RM). Mean velocity (MV) and mean propulsive velocity (MPV) were simultaneously recorded using a linear position transducer
