A sleek aluminum energy drink can and a matte scoop of white pre-workout powder sit side by side on a pale concrete gym bench, lit by soft morning window light. The can is slim and minimalist, with a muted sage green label and no legible text. Beside it is a clear glass shaker half full of cloudy, lightly frothy liquid with condensation beading on its surface. A few fine grains of powder are scattered across the bench, catching the light. Behind them, slightly out of focus, a stainless steel barbell rests on a rack, and a folded charcoal gym towel sits at the edge of the frame.

The color palette is warm neutral: oatmeal, soft gray, and sage, with a single accent of pale citrus yellow from a halved lemon wedge placed near the glass. A thin, elegant shadow from the window blinds falls diagonally across the scene, giving it an editorial, magazine-style rhythm. The composition leaves generous negative space on the right third of the frame, a smooth blurred wall in warm off-white, suitable for headline text overlay.

The shot is a low-angle, shallow depth-of-field product-style photograph, as if taken with an 85mm lens at f/2. The foreground objects are tack sharp and the background melts into creamy blur. The mood is calm, clean, and modern, like a wellness or science journal feature. Subtle film grain and gentle contrast add a tactile, contemporary lifestyle feel. There are no people, no logos, and no futuristic or sci-fi elements, just a quiet, considered still life that suggests the choice between a canned drink and a scooped supplement.

你的能量饮料或许能当健身前补剂——但有一点关键

咖啡因和牛磺酸常一起出现在能量饮料和健身前补剂中，但它们真的能提升运动表现吗？一项纳入 11 项随机对照试验（共 234 名受试者）的最新元分析显示，峰值功率和耐力时间有中等幅度的提升，且主观用力感下降；心率无显著变化，反应时间的结果因研究异质性大而难以得出可靠结论。由于样本量有限，尚不能确认牛磺酸在咖啡因之外是否还有额外作用。下面给出具体数据并说明哪些人需要慎重考虑。

A landscape editorial photograph of a lone runner's hands resting on a weathered wooden table beside a small white ceramic dish of fine white powder and a clear glass of water, shot in soft morning light. A slim matte aluminum energy drink can, unbranded with a minimalist pale sage-green label, stands slightly out of focus in the background, with a single scoop of powder dusted lightly on the tabletop. A pair of worn running shoes and a folded gray towel sit at the edge of the frame. Through a large window behind them, a blurred misty trail winds through green trees at sunrise, with warm golden light spilling across the scene.

The color palette is calm and modern: creamy off-white, sage green, warm honey gold, and soft charcoal. The composition follows the rule of thirds, with the dish and glass in the lower left third and generous negative space on the right for a title overlay. The depth of field is shallow, with a crisp focus on the powder's delicate texture and tiny glints of light on the glass rim. The mood is clean, thoughtful, and quietly energetic, like a contemporary health and science magazine feature. Natural grain, subtle film-like softness, and gentle shadows give it an authentic lifestyle-editorial look. There are no text, logos, or futuristic elements, only tactile, real-world materials like wood, ceramic, glass, cotton, and metal.

牛磺酸单独提升耐力的研究发现

BY DR. GYMBRO · 2026年10月22日

咖啡因常被提及，但能量饮料罐中的另一种成分——牛磺酸，可能正悄然发挥作用。2018 年对 10 项研究的荟萃分析显示，单次摄入牛磺酸（1–6 克）即可提升耐力表现（Hedges' g = 0.40），且剂量和补充时长对效果无显著影响。由于证据量有限且置信区间较宽，这只能算是一个有前景的信号，而非铁律。下面介绍主要结论以及更安全的使用建议。
