A bright, minimalist flat-lay photograph of two supplement scoops on a pale warm-gray stone surface, shot from directly above in soft natural window light. On the left, a matte ceramic scoop holds fine white creatine monohydrate powder, heaped in a clean mound. On the right, a second scoop of the same shape holds slightly coarser off-white beta-alanine powder, with a small, deliberate gap between the two. Each scoop sits in its own soft shadow, which suggests separation rather than combination. Between them, a thin brushed-brass ruler or a single slim line of fine powder runs across the surface and subtly divides the composition.

Around the scoops, a few restrained props in a muted editorial palette of sage green, cream, terracotta, and soft charcoal: a small glass jar with a minimalist label that has no readable text, a folded linen napkin, a single sprig of eucalyptus, and a stainless-steel shaker bottle softly out of focus in the upper corner. A few loose powder grains are scattered naturally across the stone. A small stack of blank cream index cards with a pencil rests in the lower right, hinting at research and note-taking without any legible writing.

The composition follows a clean rule-of-thirds layout, with generous negative space on the right third for headline overlay. The lighting is gentle and diffused, with long, soft shadows falling to the lower left. The color grading is calm and slightly desaturated, with creamy highlights and a subtle film-like grain. The overall look is a modern wellness and science journal cover, with an airy, trustworthy, contemporary editorial feel, shallow depth of field, and crisp detail on the powders.

肌酸+β‑丙氨酸：研究未发现叠加效益

肌酸与β‑丙氨酸常被包装成提升表现的黄金搭档，但一项涵盖 52 项随机对照试验的网络荟萃分析显示，两者并未产生协同增效。单独使用肌酸能显著提升冲刺、纵跳、重复冲刺和上肢耐力等指标；而β‑丙氨酸的效应要么不显著，要么仅在特定情境下出现。两者混合使用并未带来额外收益。下面我们一起看看该研究的做法、局限以及对补剂预算的意义。

A wide, editorial-style still life shot from a slightly elevated angle on a pale, warm-gray concrete surface lit by soft natural window light from the left. In the center foreground, a clear glass of cloudy water sits beside a small white ceramic bowl heaping with fine white baking soda powder, a wooden measuring spoon resting beside it with a light dusting of powder spilling across the surface in a graceful arc. Next to them, a minimalist digital kitchen scale in matte white shows a small portion of powder in a shallow dish. Slightly behind, an orange basketball is partially in frame, its pebbled texture catching the light, resting beside a pair of clean white and coral athletic sneakers with the laces loosely undone. A folded charcoal gray towel and a stainless steel stopwatch lie to the right, the stopwatch face crisp and legible. Three small, neatly arranged piles of white powder on a slate tile in the midground, in ascending sizes, hint at different doses without any text or labels. In the soft-focus background, the faint outline of an indoor basketball court with warm honey-colored hardwood floor and blurred lane lines stretches across the frame, glowing with golden-hour light. The color palette is restrained and modern: warm off-white, soft gray, burnt orange, and touches of sage green from a single sprig of mint or eucalyptus laid near the glass. Shallow depth of field, crisp textures on powder grains and the ball's surface, gentle shadows, subtle film-like grain. Clean negative space in the upper right for headline overlay. The mood is calm, sleek, and contemporary, like a premium health and sports science magazine cover, with a fresh, minimalist composition and no people, no text, and no futuristic elements.

小苏打+冲刺：剂量在所有测试中均优于安慰剂

BY DR. GYMBRO · 2026年10月27日

一项针对篮球运动员的随机对照试验发现，在为期四周的冲刺间歇训练中加入碳酸氢钠（小苏打），能够在垂直跳、冲刺、敏捷、Yo‑Yo距离和Wingate功率等多项指标上显著优于安慰剂。0.45 g/kg 的高剂量在每一项测量上都超过 0.3 g/kg。对团队运动员而言，这是既便宜又诱人的增益手段，但胃肠不适是需要注意的副作用。本文给出剂量计算方法、缓解胃肠不适的方案以及适用人群的说明。
