Reproducibility of Acute Caffeine Effect

NCT06606639 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 48

Last updated 2025-05-25

No results posted yet for this study

Summary

Introduction: Various studies have evaluated and verified the ergogenic effect of acute caffeine intake on sports performance, specifically on strength and power performance. However, all experimental investigations designed so far have been based on the comparison of the \"caffeine\" and \"placebo\" conditions in a single trial, not considering the reproducibility and variability of caffeine in multiple trials.

Objectives: The present study aims to evaluate the reproducibility and replicability of the acute effect of caffeine intake on energy metabolism and the muscular production of force, power and endurance, according to sex (men vs women) and type of exercise ( bench press vs squat).
