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.

중간 구간에 섭취한 Bicarb 젤, 3시간 사이클링 테스트에서 12 W 증가

BY DR. GYMBRO ·

경기 전이 아니라 경기 중에 탄산수소나트(베이킹소다)를 섭취하는 것이 최적일 수도 있다. 11명의 훈련된 사이클리스트를 대상으로 한 무작위 교차 실험에서, 3시간 라이딩 후 12분 타임‑트라이얼 파워가 탄수화물만 섭취했을 때보다 12 W 높게 나타났다. 위장 증상은 두 군 간에 차이가 없었으며, 스프린트와 2분 구간에서는 유의미한 향상이 보이지 않았다. 샘플 규모가 작고 제품은 MNSTRY가 제공했다는 점을 유념해야 한다.

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.

시간당 100 g 탄수화물 섭취가 사이클리스트를 더 빠르게 만들었지만—당이 원인은 아니었다

BY COACH RYAN ·

4시간 동안 힘든 라이드 중에 시간당 100 g 탄수화물을 섭취한 라이더는 60 g만 섭취한 사람보다 파워 저하가 적었다. 그런데 두 그룹의 근육 글리코겐 양은 거의 차이가 없었다. 무작위, 이중 맹검, 크로스오버 연구 결과는 글리코겐 보존 이상의 메커니즘이 작용한다는 점을 시사한다. 본문에서는 실험 설계와 1:0.8 비율의 포도당·프럭토스 혼합, 실제 적용 방법을 자세히 살펴보고, 누가 이 전략을 피해야 하는지, 남성만을 대상으로 한 작은 표본이 왜 중요한지도 짚어본다.
