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.

Kafa s niskom dozom kofeina nije elitnim borcima pružila nikakav podsticaj za sprint

Mislite li da vam kafa pre treninga daje dodatni podsticaj za sprint? Novo randomizovano, dvostruko slepo, crossover ispitivanje na 15 boraca nacionalnog nivoa pokazalo je da ni doze od 1,5 i 3 mg/kg (otprilike 100 i 200 mg za sportistu od 68 kg) nemaju nikakav učinak na performanse. Najviša snaga, prosečna snaga, indeks umora i čak procenjeni doprinos energetskih sistema nisu se razlikovali od dekafeinirane verzije. Ipak, to je mali negativni rezultat, a ne dokaz da kofein ne deluje; većina pozitivnih studija koristi kapsule od 3–6 mg/kg.
