Effects of caffeinated gum doses combined with post-activation performance enhancement on bench-press bar velocity: a randomized crossover study (opens in new tab)

BackgroundEvidence from randomized crossover trials indicates that both caffeine and post-activation performance enhancement (PAPE) can independently improve acute performance, but findings on their combined effects remain inconclusive. Therefore, this study examined whether 3 mg/kg or 6 mg/kg of caffeine via gum, when paired with a PAPE conditioning activity, would enhance bench-press bar velocity and total repetitions.MethodsUsing a randomized, double-blind, placebo-controlled crossover des...
