No results posted yet for this study

Summary

Introduction: Several studies have evaluated and confirmed the ergogenic effect of acute caffeine intake on sports performance, specifically on strength and power performance. However, it remains to be elucidated how CYP1A2 polymorphism influences the prolonged effects of caffeine on this type of exercise.

Objectives: The present study aims to analyze the prolonged effects of caffeine intake on neuromuscular adaptations to resistance training according to CYP1A2 polymorphism in men and women.
