A sunlit outdoor running track in late afternoon, shot from a low angle with shallow depth of field. In the foreground, a matte black bottle with a minimal off-white label sits on the edge of a warm terracotta-colored track lane, beside a folded white towel and a small glass of amber liquid catching golden light. Condensation beads on the bottle. A faint heat shimmer rises from the track surface and softens the background.

In the midground, slightly out of focus, a lean athlete in a sage-green tank top and charcoal shorts runs on a treadmill-like stretch of track, a thin sheen of sweat on their shoulders, their expression focused and calm. Their motion is gently blurred, suggesting endurance and rhythm. Long soft shadows stretch across the lane lines.

The background fades into hazy peach, apricot, and pale yellow tones, with the suggestion of tall trees and a distant stadium wall. Warm sun flare enters from the upper right, creating a subtle glow and a few soft light streaks across the frame.

Subtle editorial touches: a small notebook with a pencil and a stopwatch rest beside the bottle, hinting at data and timing without any text legible. The color palette is warm and muted, with terracotta, cream, sage, and charcoal accents, and a fine film-like grain. The composition leaves open negative space on the left third for a headline overlay. The overall mood is clean, modern, and health-journal inspired, natural and aspirational, with a calm scientific curiosity rather than hype.

热天酮饮料：更持久的耐力和更敏锐的记忆？

酮饮料原本被视为燃脂黑客的工具，但最新的热应激实验显示，它们也可能帮助你在炎热中更有底气地坚持到底。17 名受过耐力训练的男性摄入酮单酯+咖啡因后，进行 90 分钟、气温 34°C、相对湿度 45% 的负荷跑步，耐力极限时间延长至 8.9 分钟，而碳水+咖啡因组为 7.0 分钟。1‑back 工作记忆的正确率亦有所提升，而心率和核心体温并未出现显著差异。2‑back、反应时及击打规避任务则未见效益，且本研究样本量小、仅限男性且为单次测试。下面是数据揭示的内容以及未能说明的部分。

A wide, softly lit morning scene on a pale oak desk beside a window, shot from a slightly elevated three-quarter angle. In the foreground, a clear glass of water is half-filled with dissolved white creatine powder, tiny suspended particles catching the light. A wooden scoop heaped with fine white powder rests beside it, with a few grains scattered across the wood. A matte ceramic mug of black coffee sits slightly out of focus to the right, with a thin curl of steam. Behind them, a rumpled linen-white bed with a muted sage-green throw blanket suggests a sleepless night. Early dawn light spills through sheer curtains and creates long, gentle shadows and a warm peach-and-pale-blue gradient on the wall. On the desk, a minimalist analog alarm clock reads close to 6 a.m., and a small open notebook with a pen lies beside it, its handwriting blurred. A single green plant in a terracotta pot adds a fresh organic touch at the left edge. The color palette is calm and editorial: cream, soft sage, warm oak, dusty peach and muted slate blue. The depth of field is shallow, with crisp focus on the glass and scoop and a creamy bokeh background. The mood is quiet, restorative and contemplative, like a modern wellness magazine or a trendy health journal cover. The composition leaves open negative space in the upper left for title overlay. The image has a natural film-like texture, soft contrast and a clean, minimalist, lifestyle-photography look, with no text, logos or futuristic elements.

一次 0.35 g/kg 肌酸剂量能在数小时内抵御因失眠引起的脑雾

BY DR. GYMBRO · 2026年10月15日

肌酸是健身房里最受信赖的补剂，但 2024 年的一项研究显示，一次 0.35 g/kg（约 25‑28 g）的剂量在数小时内即可对抗因睡眠不足导致的脑雾。实验让受试者在 21 小时不睡，肌酸改变了大脑能量标记，阻止了脑 pH 下降，并提升了认知表现和处理速度。该剂量约是常规每日 3‑5 g 的五倍，且研究样本量小、环境受控；胃肠不适的风险真实存在，且尚未有重复大剂量的安全性数据。下面我们一起看看研究到底说明了什么，以及为什么现在仍不建议改变你的日常补剂方案。
