The Role of Caffeine in Enhancing Physical Performance: From Metabolism to Muscle Function

Abstract

Introduction: Caffeine, a widely consumed stimulant, is recognized for its ability to block adenosine receptors, thereby enhancing alertness and possibly physical performance. Recent research examines caffeine's effectiveness in enhancing athletic performance, with numerous athletes supplementing with caffeine to gain a competitive edge. The aim of this study: This article examines the complex relationship between caffeine and the physical performance of athletes, including its effects on the central nervous system, metabolism, muscle function, and its application in a variety of sports, as well as potential gender differences and individual response variations. Materials and methods: This review was based on available data collected in the PubMed database and Google Scholar web search engine using the key words caffeine, athletic performance, physical performance Conclusions: Caffeine boosts muscle, cognitive, and metabolic function in volleyball and cycling. Caffeine boosts muscle contractility, endurance, and focus, but details matter. Caffeine effects and sports outcomes vary by gender, emphasizing the need for individualized supplementation. Dosage, timing, and physiological conditions affect results, research shows. Caffeine boosts performance, but athletes, coaches, and practitioners should be careful. To maximize caffeine's benefits and minimize side effects, athletes must be treated individually and by sport.
