A cyclist in profile, riding a sleek road bike along a quiet coastal road in warm golden-hour light, shot from a low side angle with a shallow depth of field. The rider wears a muted sage-green jersey, black bib shorts, a matte white helmet, and sunglasses. Their face shows calm, focused fatigue, with a faint sheen of sweat on the forearms. One hand is lifted slightly from the handlebars, holding a small, unbranded matte gel packet in soft cream and coral tones, just before opening it. The road curves gently behind them toward a hazy, softly blurred horizon of pale sea and distant hills, with long amber shadows stretching across the asphalt. In the foreground, slightly out of focus, a few gel sachets and a bike bottle rest on a weathered stone wall at the left edge of the frame, adding editorial depth. Fine dust and sunlight glow in the air. The palette is warm and restrained: butter yellow, soft peach, sage, and slate blue, with gentle film-like grain. The composition leaves open negative space in the upper right, a pale gradient sky, for headline overlay. The overall look is a modern, minimalist sports-science magazine photograph: natural, premium, and clean, with realistic textures, cinematic but understated color grading, and no text, logos, or graphics.

Bikarbonatni gelovi tokom vožnje povećavaju snagu za 12 W u 3‑satačnom testu

BY DR. GYMBRO ·

Šta ako je najpogodnije uzimati bikarbonat ne pre starta, već tokom same trke? Novo randomizovano, krstareće ispitivanje na 11 obučenih biciklista testiralo je gelove sa bikarbonatom i ugljenim hidratima tokom tročasovne vožnje. Posle zamora, snaga u 12‑minutnom pokušaju bila je za 12 W veća nego pri ishrani samo ugljenim hidratima, a gastrointestinalni simptomi nisu se razlikovali. Međutim, sprint i dvominutni napori nisu pokazali značajan dobitak, uzorak je bio mali, a proizvodi su dolazili od MNSTRY‑a. Evo šta brojevi zaista pokazuju.
A cyclist in a fitted matte-black kit, shot from a low three-quarter angle, rides a sunlit country road at early morning, slightly out of focus with soft motion blur on the wheels. In the foreground on the left sits a rustic wooden table with a tall glass of deep magenta beetroot juice. Condensation beads on the glass, and the light catches its vivid jewel-toned color. Beside it lie two whole beetroots with their leafy red-veined greens still attached, and one halved beet shows concentric crimson-and-pink rings. A small linen napkin and a scatter of water droplets add an editorial still-life feel. The background is a gently rolling landscape with golden-green fields and a thin ribbon of asphalt curving toward the horizon. Pale mist hangs low and warm sunlight comes from the right, creating long soft shadows and a golden rim light on the glass and the cyclist's silhouette. The shallow depth of field keeps the juice and beets crisp while the rider stays a dreamy blurred suggestion of speed. The palette is rich magenta, burgundy, warm cream, sage green, and soft gold, with muted, slightly desaturated tones in the background so the beetroot color stands out. The composition follows the rule of thirds, with the still-life in the lower left third and open negative space in the upper right for the title. The overall look is a clean, modern lifestyle-magazine photograph with natural film-like grain, calm and athletic, and no text, logos, or futuristic elements.

Sok od cvekle pre vremenskog pokušaja: kako 0,5 L skraćuje vreme na 4 km i 16,1 km za gotovo 3 %

BY DR. GYMBRO ·

Mali, ali značajan crossover eksperiment iz 2011. godine istražio je da li jedan gutljaj soka od cvekle može ubrzati realne biciklističke testove vremena. Devet takmičarskih muških biciklista popilo je 0,5 L soka bogatog nitratima (oko 6,2 mmol nitrata) otprilike 2,5 sata pre trke. Plazma nitrit se više nego udvostručila, prosečna snaga je porasla, a rezultati na 4 km i 16,1 km poboljšali su se za 2,8 % i 2,7 %. Ključna poenta je da je potrošnja kiseonika ostala nepromenjena, što ukazuje na bolju ekonomiju vožnje, a ne na jači aerobni motor.
