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.

Bikarbonat gelovi tijekom vožnje dodali 12 W u kasnom dijelu tro‑satnog testa

BY DR. GYMBRO ·

Što ako je najbolji trenutak za uzimanje bikarbonata ne prije utrke, nego tijekom nje? Randomizirano, križano ispitivanje na 11 treniranih biciklista testiralo je gelove s bikarbonatom i ugljikom tijekom tro‑satne vožnje. U 12‑minutnom testu snaga je bila 12 W veća nego uz samo ugljik, a gastrointestinalni simptomi nisu se razlikovali. Međutim, sprintovi i 2‑minutni napori nisu pokazali značajnu dobit, uzorak je bio mali, a proizvode je osigurao MNSTRY. Evo što stvarni brojevi zaista znače.
A cyclist in mid-ride, photographed from a low three-quarter side angle on a quiet country road at golden hour, wearing a matte navy jersey and a white helmet, with soft warm light catching the sweat on his forearms. His expression is calm and focused. The road bends gently through rolling green fields, and the background is softly blurred with creamy bokeh. In the foreground on the left, a styled flat-lay-inspired still life sits on a weathered wooden surface and blends into the scene. It includes two clear water bottles with pale citrus-tinted liquid, a few torn energy gel packets in muted coral and sage, and a small pile of dried apricots and sliced banana. A handful of glossy orange slices adds a bright accent. The shallow depth of field keeps the cyclist sharp in the middle distance while the foreground items are gently softened. The color palette is warm and editorial: soft peach, muted terracotta, sage green, cream, and deep navy. The light is natural and golden, with long, gentle shadows and a slight film-grain texture, like a high-end lifestyle or sports-science magazine spread. The composition follows the rule of thirds, with the cyclist on the right third and open negative space in the upper left, suitable for headline overlay. The mood is energetic yet thoughtful, clean and modern, and the photograph feels authentic rather than staged. There are no logos, no readable text, and no futuristic or sci-fi elements. The overall look is crisp, airy, and refined, in the style of a contemporary health and performance journal cover.

100 g ugljikohidrata po satu držalo je bicikliste bržima — a glikogen nije bio razlog

BY COACH RYAN ·

Četiri sata nakon intenzivnog treninga, biciklisti koji su unosili 100 g ugljikohidrata po satu izgubili su manje snage nego oni s 60 g. Iznenađujuće, razina glikogena u mišićima bila je otprilike ista. Ova randomizirana, dvostruko‑slijepa, crossover studija na 15 treniranih muškaraca upućuje na mehanizam koji nije povezan s očuvanjem glikogena. Razlažemo brojke, protokol 1:0,8 glukoza : fruktoza i kako ga primijeniti. Također obrađujemo tko bi ga trebao izbjegavati i zašto je uzorak isključivo muškaraca ograničenje.
