A wide, minimalist editorial scene of an athlete's hands and forearms gripping the handles of a rowing ergometer, shot in soft natural light from a large window in a clean, airy training studio. The athlete is mid-pull, forearm muscles subtly defined, a light sheen of sweat on the skin, chalk dust floating in the air. In the foreground on a pale oak bench sits a small ceramic scoop of fine white powder beside a matte glass of water, with a few loose white capsules arranged neatly in a gentle curve. A minimalist analog stopwatch with a clean white face lies next to them, its hand paused near the two-minute mark.

The color palette is calm and modern: warm off-white, soft sand, muted sage green, and a single accent of coral orange in the stopwatch hand and the rower's wristband. The background is softly blurred concrete and pale wood with long, gentle shadows stretching across the floor. Shallow depth of field keeps the hands, powder, and stopwatch crisp while the rest dissolves into creamy bokeh.

Composition follows the rule of thirds: the rowing handles and hands occupy the right third, the bench still life sits in the lower left, and open negative space in the upper left leaves room for a title overlay. The mood is focused, quiet, and intentional, like a high-end health and science journal feature. Fine film grain, subtle matte finish, editorial photography style, natural color grading, and no text or logos.

Djeluje li beta‑alanin? Meta‑analiza kaže da za napore od 60–240 sekunde

BY DR. GYMBRO · 14. lis 2026.

Beta‑alanin se dugo promovira kao sredstvo koje ublažava neugodan osjećaj izgaranja tijekom intenzivnog treninga, ali zaista li djeluje? Meta‑analiza od 15 studija i 360 sudionika otkriva stvarnu, iako skromnu, prednost – prosječni porast od 2,85 %. Najveći učinak primjetan je kod napora koji traju 60–240 sekunde, dok je manji ili nepostojeći izvan tog vremenskog okvira. Članak također razmatra tipičan protokol učitavanja od 3,2–6,4 g dnevno te kako podjela doze smanjuje neugodni trnci. Najviše koristi očekuju se kod sportaša koji se natječu u disciplinama od jedne do četiri minute.
