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.

Dupliranje doze kofeina jedva je pomoglo bokserima – što su pokazali rezultati

BY DR. GYMBRO · 27. lis 2026.

Mislite li da dvostruka doza pre‑treninga donosi dvostruku izvedbu? Novo križano ispitivanje na 15 natjecateljskih boksera uspoređivalo je 3 mg/kg i 6 mg/kg kofeina, a veća doza nije bila dosljedno bolja. Obje doze su poboljšale visinu skoka i snagu nakon 60 minuta, dok je 6 mg/kg bila ispred samo u nekim parametrima, poput snage balističkih sklekova i momenta ekstenzije koljena. U članku su prikazani izračuni doze po kilogramu tjelesne mase, preporučeno vrijeme uzimanja i važne napomene – uključujući činjenicu da se sam udarac nije testirao.
