Coffee Benefits vs Cons: Brewing Athletic Performance
For athletes, coffee is more than just a morning ritual—it’s a potential powerhouse for boosting physical performance. From enhancing endurance to aiding post-exercise recovery, coffee’s benefits are increasingly supported by science. But as with anything, there’s a balance between benefits and potential drawbacks. Let’s dive into the research to explore coffee benefits vs cons, helping you decide whether to make it a key part of your athletic routine.
With over 20 years of strength training experience and a decade of expertise in sports acupuncture, I’ve seen how simple changes—like tailoring coffee intake—can enhance athletic performance and recovery. Based in Vancouver, BC, I combine my fitness background with techniques like electro-acupuncture and cupping to help athletes optimize endurance, strength, and recovery. My holistic approach includes personalized recommendations for caffeine timing and amounts, ensuring each athlete’s intake suits their body size, tolerance, and performance goals while minimizing potential drawbacks.

The Endurance Edge: Coffee and Stamina
Coffee is a well-known source of caffeine, which can enhance endurance performance when consumed before exercise. A review highlighted that coffee containing 3-8 mg/kg of caffeine significantly improved endurance in time-to-exhaustion and time-to-completion trials. Athletes reported feeling less fatigued, suggesting coffee may reduce perceived exertion during prolonged activity.
This makes coffee a viable alternative to caffeine supplements for runners, cyclists, and anyone involved in endurance sports.
Strength and Power: Coffee’s Impact on Resistance Training
Caffeine doesn’t just benefit endurance athletes—it’s also effective for boosting performance in resistance exercises. Recent research found that caffeine enhances one-rep max strength, muscular endurance, and power output across a variety of resistance exercises. Interestingly, doses as low as 2-3 mg/kg were found to be just as effective as higher doses.
On my morning strength training days, which are a regular part of my weekly routine, I brew just enough coffee for two cups—one to wake up and another to enjoy before my workout. This ritual helps me feel sharp and energized, setting the tone for a strong session.
Post-Workout Recovery: Coffee’s Role in Muscle Glycogen Replenishment
Beyond performance, coffee also plays a surprising role in recovery. A randomized controlled trial showed that coffee, when consumed with carbohydrates post-exercise, significantly enhanced muscle glycogen replenishment compared to a carbohydrate-only beverage. This suggests coffee could be a useful addition to your post-workout nutrition, aiding in faster recovery for endurance athletes.
For me, grabbing a coffee (and perhaps a treat) post-run is non-negotiable. After finishing run, I’ll usually swing by one of my favourite local spots before heading home. Not only does it help kickstart recovery, but it also gives me a chance to savour the accomplishment of the workout.
Coffee Benefits vs Cons: The Drawbacks
While coffee offers significant advantages for athletes, overconsumption or improper use can lead to negative effects. Up to 400 mg of caffeine daily—roughly four cups of brewed coffee—is safe for most adults. Exceeding this limit can result in side effects such as:
- Headaches
- Insomnia
- Nervousness and irritability
- Frequent urination
- Fast heartbeat or muscle tremors
For caffeine-sensitive individuals, even small amounts may cause restlessness or disrupt sleep. Consuming caffeine too late in the day can create a cycle where poor sleep leads to greater reliance on caffeine, further interfering with recovery.
Athletes should also be cautious about combining caffeine with certain medications or supplements. For example, mixing caffeine with ephedrine or theophylline can increase the risk of adverse health effects.
The key is to understand your body’s tolerance and adjust your caffeine habits accordingly to maximize performance while minimizing potential side effects.
A Coffee Lover’s Perspective
As a coffee enthusiast and fitness advocate, coffee naturally fits into my daily routine. Whether it’s a pre-workout boost or a post-run brew, it’s more than just about performance—it’s a simple ritual I enjoy. While I usually brew my own, Vancouver’s coffee scene occasionally inspires me to grab a cup while I’m out, offering a nice change of pace.

Striking the Right Balance
Coffee can be a powerful ally for athletes, enhancing endurance, strength, and recovery. However, understanding coffee benefits vs cons is key to using it effectively. By keeping caffeine intake within recommended limits, timing consumption appropriately, and listening to your body, you can enjoy coffee’s performance-enhancing effects while avoiding potential pitfalls.
Whether it’s a pre or post-workout brew (or in my case, both), or a moment of reflection at your favourite local café, coffee is more than just a drink—it’s a performance partner and a source of joy in the athletic journey.
