Coffee: An Unexpected Ally for Sports Performance
A recent scientific review published in the journal Nutrients by researchers from the Lodz University of Technology and the University of Opole (Poland) analyzed studies from the last 25 years and confirmed what many athletes already suspected: coffee can have a direct impact on endurance performance and muscle recovery.
The analysis, which reviewed research conducted between 2000 and 2026, details how caffeine—the main active component in coffee—favors endurance capacity and reduces the perception of effort during demanding physical activities, especially under fatigue or sleep disruption.
How Does Caffeine Work in the Body?
Caffeine blocks adenosine receptors in the central nervous system. This keeps you alert and diminishes the feeling of tiredness, allowing you to tolerate effort better in long-duration sports. The study highlights that the positive effects are most robust in prolonged aerobic activities and less consistent in strength and power exercises.
Dosage and Timing: How to Take Coffee for Better Performance
According to Dr. Sebastian La Rosa, a longevity expert, the effective caffeine dose for improving training is between 3 and 6 milligrams per kilogram of body weight, consumed about 30 to 60 minutes before exercising. For a 70 kg cyclist, a dose of 3 mg/kg equals roughly 210 mg of caffeine, which can be obtained from about two or three cups of filtered coffee.
The specialist warns about two common mistakes: "If you train late, you shouldn't use it because it will clearly affect your sleep quality, and sleep quality is more important than caffeine". He also notes that many people use caffeine to mask chronic poor sleep, which is "bread today, hunger tomorrow".
Other Coffee Compounds: Polyphenols
Beyond caffeine, coffee contains polyphenols, diterpenes, trigonelline, and melanoidins. These compounds have an indirect role in performance, linked to the modulation of metabolic, inflammatory, and recovery processes. Polyphenols have antioxidant properties that aid recovery after exercise, while melanoidins may influence gut microbiota.
The Longevity Finding
A team from Texas A&M University identified that coffee compounds, such as caffeic acid, activate the NR4A1 receptor, a protein linked to aging and cellular stress response. This interaction was associated with reduced cellular damage and could explain why coffee consumption is linked to greater longevity and a lower risk of chronic diseases.
Precautions: How Much Coffee Is Safe
The U.S. Food and Drug Administration (FDA) and the American Heart Association consider moderate consumption of up to 400 mg of caffeine per day (about 4 cups of coffee) safe. However, individual response varies based on genetics, habitual intake, and timing. Consuming caffeine late in the day can disrupt sleep, compromising recovery and future performance.
In summary: coffee can be a great ally to improve the quality of your training, but it should be used wisely. It does not replace good rest, and the dose must be adjusted to each person. As Dr. La Rosa concludes, "caffeine does not directly build muscle; what it generally does is raise the quality of your training".
