In a study at +32 °C and 60% humidity, taurine extended time to exhaustion: 6 grams worked in men, 4 in women. Here is why that difference is almost certainly not about sex at all.
An ordinary optical sensor on the wrist cannot measure glucose — not because the algorithms are bad, but because it never collects the signal in the first place. We unpack the physics, a fresh re-analysis of the data, the FDA position, and what actually works.
Aerobic work drives glucose down, while intervals can push it up — and that changes the entire tactic. We break down target ranges, insulin adjustments and the 90-minute rule you should be discussing with your doctor.
A meta-analysis of 23 studies found a significant link with performance for just one pollutant — ozone. PM2.5 particles and the overall air quality index showed no reliable effect. Here is what that changes in practice.
Endurance-sport enthusiasts get atrial fibrillation 2–5× more often, but the relationship is U-shaped: moderate training protects the heart, while chronic mega-volumes may raise the risk. We break down the data and the signs that it's time to see a doctor.
Almost everyone takes a painkiller before the start, yet it does nothing for performance. Here is what the research says about kidneys, sodium and recovery — and what to do about pain instead of reaching for a pill.
Fish oil is no “magic boost” to your results, but 2–4 g of EPA+DHA a day noticeably dampens inflammation, muscle damage and soreness. And it works strongest precisely in recreational athletes.
A good taper adds an average of 2–3% to your race result. We break down what the research says and lay out a ready-made 3-week plan for the marathon and half marathon.
A meta-analysis of 33 studies and 519 athletes settles the question: beetroot nitrate delivers a small but real gain in sprinting, power, and VO₂max. We break down the dose, the timing, and why in elite athletes the effect often “gets eaten up.”
A fresh review in the journal Nutrients gathered 38 creatine studies in endurance sports. The verdict: it has little effect on “pure” aerobic work, but genuinely helps sprints, strength work, and recovery. We break down who needs it and how to take it.
The U.S. National Academies revised the reference intakes for sodium and potassium and, for the first time, introduced a category aimed at reducing disease risk. Let's break down how to read these numbers if you train for hours.
In a marathon or an ultra, drinking too much can sometimes be more dangerous than drinking too little. Let's unpack what hyponatremia is, why endurance sport is a risk zone, and how to drink wisely.
