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.

中途补充碳酸氢盐凝胶在3小时骑行测试中提升12瓦

BY DR. GYMBRO ·

如果最佳的碳酸氢盐摄入时机不是赛前，而是赛中会怎样？一项针对 11 名受训自行车手的随机交叉试验在 3 小时骑行过程中同步摄入碳酸氢盐＋碳水凝胶。结果显示，疲劳状态下的 12 分钟计时赛功率比单纯碳水高出约 12 瓦，且胃肠不适程度相同。但冲刺和 2 分钟全力测试并未出现显著提升，样本量也很小，且产品由 MNSTRY 提供。以下为数据的客观解读。
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.

时间赛前的甜菜根汁：0.5 L 如何让 4 km 与 16.1 km 骑行时间缩短近 3%

BY DR. GYMBRO ·

2011 年的一项小规模但影响深远的交叉实验检验了单次饮用甜菜根汁是否能让真实的自行车计时赛更快。九名竞技男骑手在比赛前约 2.5 小时饮下 0.5 L、含约 6.2 mmol 硝酸盐的甜菜根汁。血浆亚硝酸盐浓度翻倍，平均功率提升，4 km 与 16.1 km 的成绩分别提升了 2.8% 与 2.7%。关键在于氧气摄取量没有变化，说明提升来自更好的骑行经济性，而非更大的有氧引擎。
