CAFFEINE & PERFORMANCE

Caffeine & Performance

Caffeine is one of the most studied ergogenic supplements in sports. It contributes to increased alertness, endurance, and power, making it a valuable resource for athletes across various disciplines. But what makes caffeine such an effective compound?

🧠 Mechanism of Action:

🛑Adenosine inhibition → Increases alertness → Reduces fatigue → Improves decision-making under effort, reducing cognitive lapses in moments of exhaustion.🔥

🔥 Optimization of energy metabolism → Enhances fatty acid utilization → Reduces dependence on muscle glycogen → Increases metabolic efficiency during training.

Increased intracellular calcium release → Improves muscle fibre activation → Increases contraction strength → Reduces muscle fatigue in high-intensity exercises.

❤️Improved blood Circulation → Enhances muscle oxygenation → Facilitates the delivery of essential nutrients and the removal of accumulated metabolites.

🏆 Impact on Sports Performance:

🏃‍♂️Increased aerobic endurance → Improved running economy → Reduced perception of effort → Ability to maintain high intensities for longer periods.


💪Enhanced strength and power → Greater force production → Increased ability to perform more repetitions until exhaustion → More efficient recruitment of fast-twitch muscle fibers.


Improved sprint performance and explosive efforts → Intensified mental focus → Increased speed and explosiveness in short-duration activities.


🎯Enhanced coordination and reaction times → Faster neuromuscular responses → Greater precision and reactivity in sports requiring agility and sharp reflexes.

☕ Caffeine Consumption:

📏Recommended dosage: 3-6 mg/kg of body weight → Consume 30-60 minutes before exercise →

Response may vary depending on individual tolerance and regular consumption adaptation.


🍵Dietary sources: Coffee, tea, capsules, gels → Bioavailability may be influenced by intake method and nutritional context.


🧘‍♂️Strategic combination → Caffeine + L-Theanine → Improves concentration and focus without causing side effects such as nervousness or excessive heart rate increase.  

⚠️ Precautions and Possible Adverse Effects:

🚫Doses exceeding 9 mg/kg → Increased risk of insomnia, anxiety, and gastrointestinal discomfort.


Excessive consumption may lead to: Tachycardia, tremors, irritability, and sleep disturbances, compromising muscle recovery and long-term performance.  

🔋Energy in the right dose. Maximum performance. Push your limits! 🚀
