Kreatin prije ili poslije treninga? Malo istraživanje daje prednost uzimanju poslije treninga

BY DR. GYMBRO · 14. lis 2026.

Trebate li uzimati kreatin prije ili nakon treninga? Istraživanje iz 2013. godine na 19 muškaraca‑bodybuildera pokazalo je da je doza nakon treninga malo nadmašila dozu prije treninga u pogledu mišićne mase, masnog tkiva i bench pressa. Međutim, formalni statistički test nije otkrio značajnu razliku između grupa, a autori su se oslonili na opreznu interpretaciju da je „moguće korisniji”. Evo što podaci zaista pokazuju, zašto je veličina uzorka važna i kako primijeniti rezultate uz jednostavnu dnevnu dozu od 5 g.

A landscape, editorial-style flat lay photographed from above on a pale oak gym bench or a matte light-gray concrete surface. On the left side, a clear glass of water sits next to a small matte white ceramic bowl of fine white creatine powder, with a wooden scoop resting beside it and a few loose grains scattered naturally on the surface. In the center, a modern analog wall-style clock face is replaced by a simple minimalist stopwatch in brushed steel, its hands paused, subtly suggesting timing without any text or numbers emphasized. On the right, a neatly folded charcoal gym towel and a single chalk-dusted dumbbell handle enter the frame at the edge, with a faint dusting of white chalk on the wood. A small linen notebook with a pencil rests slightly off-center, its pages blank, hinting at data and study without any readable writing.

The color palette is soft and restrained: warm cream, oatmeal, sage green, and muted slate, with one accent of terracotta orange in the pencil or a small ceramic dish. Light comes from a large window at the upper left, casting long, gentle diagonal shadows and a soft highlight across the glass of water, creating delicate caustic reflections on the surface. The depth of field is shallow, with the creatine bowl and scoop in crisp focus and the edges softly blurred. The composition leaves generous negative space on the upper right for a headline overlay. The overall feel is calm, clean, and contemporary, like a wellness and science journal's cover image, with natural textures, subtle film grain, and a refined, premium magazine look. No people, no logos, no text, and no futuristic elements.

Kreatin prije ili nakon treninga? Malo istraživanje sugerira prednost uzimanja nakon treninga

BY DR. GYMBRO · 14. lis 2026.

Trebate li uzimati kreatin prije ili poslije treninga? Studija iz 2013. na 19 muškarca‑bodybuildera pokazala je da je doziranje nakon treninga blago nadmašilo onaj prije treninga po pitanju mišićne mase, masnog tkiva i bench pressa. Međutim, formalni statistički test nije otkrio značajnu razliku između grupa, a autori su se oslonili na opreznu pretpostavku da je možda korisnije. U nastavku su stvarni podaci, zašto je veličina uzorka važna i kako primijeniti rezultate uz jednostavnu dnevnu dozu od 5 g.

A wide editorial still life on a pale, warm-gray stone surface lit by soft morning window light from the left. In the foreground, a rustic ceramic bowl in matte oatmeal glaze holds dried ashwagandha roots, pale tan and gnarled, with a few scattered beside it. A small wooden scoop dusted with fine golden-beige powder rests next to the bowl. Behind them, a few olive-green ashwagandha sprigs with small orange-red berries in papery husks arc across the frame, adding a quiet pop of color.

Midground right: a matte black chalk-dusted dumbbell handle and a single brushed-steel weight plate lean casually against a linen-textured backdrop in muted sage. A folded cream cotton towel and a slim notebook with a pencil suggest a training log. The notebook is open to blank, softly lined pages with no legible text.

The background fades into a gentle blur of neutral beige and soft terracotta tones, with a hint of a plant shadow cast across the wall in dappled light. Fine dust and powder particles float in the light beams, giving a tactile, organic feel.

The composition follows the rule of thirds: botanical elements on the left and center, gym elements on the right, and negative space in the upper right for headline overlay. Shallow depth of field, crisp focus on the roots and powder, creamy bokeh behind. Color palette: sage green, warm sand, terracotta, charcoal black, and a touch of burnt orange. The mood is calm, modern, and trustworthy, like a premium wellness and science magazine. Photographed on a 50mm lens, natural grain, subtle film-like contrast, clean minimalist styling, high-end editorial photography.

Drevna biljka koja je nadmašila placebo u 8‑tjednom podizanju snage, mišićne mase i testosterona

BY DR. GYMBRO · 14. lis 2026.

Može li tisućljetni ajurvedski korijen zaista nadmašiti placebo? U 8‑tjednoj randomiziranoj studiji na 57 početnika, muškarci koji su uzimali 300 mg ekstrakta ashwagandhe dva puta dnevno postigli su veći porast snage u bench‑pressu, veći obujam ruku i prsnog koša te veći porast testosterona u odnosu na grupu s placebom. Također su izgubili više tjelesne masnoće. Problem je što je studija mala, kratka i ograničena na početnike‑muškarce. Evo što podaci pokazuju, kako je doziranje funkcioniralo, kome može koristiti i zašto treba ostati skeptičan.
