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 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.

비트루트 주스와 타임 트라이얼: 0.5 L가 4 km와 16.1 km 사이클링 시간을 약 3% 단축

BY DR. GYMBRO ·

2011년 소규모이지만 영향력 있는 교차 실험에서 비트루트 주스 한 잔이 실제 사이클링 타임 트라이얼을 빠르게 만들 수 있는지 확인했습니다. 9명의 클럽 수준 남성 사이클리스트가 레이스 약 2.5시간 전에 0.5 L(≈ 6.2 mmol 질산염) 비트루트 주스를 섭취했습니다. 혈장 아질산염 농도가 두 배 이상 상승했고 평균 파워가 증가했으며, 4 km와 16.1 km 기록이 각각 2.8%와 2.7% 개선되었습니다. 특히 산소 섭취량은 변하지 않아, 단순히 ‘엔진’이 강해진 것이 아니라 사이클링 효율이 향상된 결과임을 시사합니다.
