A wide, editorial-style still life shot from a slightly elevated angle on a pale oak gym bench, bathed in soft morning window light. In the center sits a matte ceramic cup of black coffee with delicate steam curling upward, flanked by a small white scoop of coffee beans and two identical glass vials, one filled with a few grains of fine powder and one empty, hinting at dose comparison. Next to the cup rests a pair of worn white boxing hand wraps, loosely coiled, and a slim black stopwatch with its face softly visible. In the foreground, a minimalist notebook lies open with blurred handwritten numbers and a simple pen sketch of a bar graph with bars of equal height, subtle and unreadable, suggesting a null result without any legible text. A small brass kitchen scale sits to the side with a few coffee beans on its tray.

In the soft-focus background, a boxing gym interior is visible: a hanging heavy bag in muted charcoal, exposed brick wall painted off-white, and tall windows casting long diagonal light across the floor. The color palette is warm and restrained: cream, sand, espresso brown, soft charcoal, with a single accent of muted terracotta orange in the hand wraps and a faint sage green in the notebook cover. Shallow depth of field with creamy bokeh, fine film grain, and gentle shadows give it a contemporary lifestyle-magazine and wellness-journal feel. The composition leaves generous negative space on the left third for headline overlay. Clean, calm, trendy, and tactile, with natural textures like wood grain, ceramic glaze, and cotton fabric. No people, no text, no futuristic elements.

Le café à faible dose de caféine n’améliore pas les sprints chez les combattants d’élite

BY DR. GYMBRO · 23 oct. 2026

Vous pensez que votre café pré‑entraînement booste vos sprints ? Une étude randomisée, en double‑aveugle et croisée, menée chez 15 athlètes de combat de niveau national n’a trouvé aucun bénéfice de performance avec des doses de caféine de 1,5 et 3 mg/kg (environ 100 et 200 mg pour un athlète de 68 kg). La puissance maximale, la puissance moyenne, l’indice de fatigue et les contributions estimées des systèmes énergétiques ne diffèrent pas du décaféiné. Il s’agit toutefois d’un petit résultat nul, pas d’une preuve que la caféine échoue, et la plupart des études positives utilisent des gélules à 3–6 mg/kg. Voici le calcul des doses, les limites et ce qu’il faut réellement faire avant votre prochaine séance intense.
