Caffeine FAQ
Caffeine is one of the most widely used performance enhancers in the world, and for good reason! Research shows that it can improve focus, increase energy expenditure, decrease perception of fatigue and exertion and increase reaction time. But like all good things, there’s also potential risk factors.
Potential Risks:
GI Distress: High doses of caffeine can lead to gastrointestinal issues, which can be especially problematic during endurance events.
Sleep Disruption: Caffeine can interfere with sleep, which is crucial for recovery. Timing your caffeine intake is key to avoiding this issue. Aim to avoid caffeine within 6 hours of bedtime.
Overconsumption: Too much caffeine can lead to jitteriness, increased heart rate, and even anxiety.
Dehydration: Caffeine is a mild diuretic when consumed in doses larger than normal, causing dehydration and electrolyte imbalances.
How to Use Caffeine Effectively as an Athlete:
Dosage: Evidence suggests a dose of 0.9-2.7mg/lb bodyweight about 60 minutes before exercise is effective for performance enhancement.
Test in Training: Before using caffeine on race day, test your response during training to avoid any unwanted side effects.
Have you ever noticed your body does not respond well to caffeine? Or have you ever actually calculated how many milligrams of caffeine you are consuming everyday? Caffeine is a stimulant that can often cause more harm than good when used improperly.
Instead of guessing, work with a Registered Dietitian to figure out how you can effectively enhance performance with OR without the use of caffeine!
