A landscape editorial photograph with a modern, clean magazine feel, shot on a pale warm-gray concrete surface in soft natural window light from the left. In the foreground, two matte white ceramic espresso cups sit side by side. The left cup holds a small amount of dark espresso with golden crema. The right cup is filled twice as high. Beside them, two small stainless steel scoops hold fine coffee-colored powder, one half full and one heaped, suggesting a dose comparison without any text or labels. A pair of worn red leather boxing gloves rests slightly out of focus behind the cups, laces loosely draped, with a white hand wrap rolled neatly beside them. A minimalist digital kitchen scale in matte black sits at the edge of the frame, with a few roasted coffee beans scattered across the surface. In the soft-focus background, a boxing gym corner appears: a hanging heavy bag in muted charcoal, pale wood plank flooring, and a tall window with diffused morning light. The palette is warm cream, espresso brown, brick red, and soft slate gray, with gentle shadows and a shallow depth of field. The composition follows the rule of thirds, with the cups and scoops in the lower left third and open negative space on the right for headline overlay. The look is tactile and refined, like a high-end health and performance journal. It has natural grain, subtle contrast, and a calm, confident mood. There are no people, no text, no logos, and no futuristic elements.

Doubler votre caféine n’a guère aidé les boxeurs — voici ce qui a réellement fonctionné

BY DR. GYMBRO · 27 oct. 2026

Vous pensez qu’une double dose de pré‑entraînement signifie une performance doublée ? Une étude croisée menée sur 15 boxeurs de haut niveau a comparé 3 mg/kg et 6 mg/kg de caféine ; la dose la plus élevée n’a pas été systématiquement meilleure. Les deux dosages ont amélioré la hauteur du saut et la puissance à 60 minutes, tandis que 6 mg/kg ne s’est démarquée que sur quelques paramètres comme la puissance du push‑up balistique et le couple du genou. Vous trouverez ci‑dessous le tableau de conversion mg / kg, le timing recommandé et les réserves importantes, dont le fait que le coup de poing n’a jamais été testé.
