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 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?

BY DR. GYMBRO ·

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, editorial-style flat lay photographed from above on a pale warm-gray linen surface in soft natural window light. At the center, a small open amber glass jar tips gently onto its side, spilling a few cream-colored capsules across the fabric. Next to the jar sits a loose arrangement of fresh mushrooms: a cluster of golden-tan reishi with glossy, lacquered caps, a few slender white enoki stems, a halved shiitake showing its pale gills, and a curl of turkey tail with concentric bands of rust, cream, and charcoal. A small wooden scoop holds a pile of fine beige mushroom powder.

On the left third of the frame, a matte black sports watch with a minimal face lies beside a folded sage-green running shirt and a pair of lightweight off-white running shoes, hinting at athletic training without showing a person. A slim white notebook with a single pencil rests nearby, open to a blank page with a faint hand-drawn line graph trending upward, in thin graphite strokes.

On the right side, a pair of clear glass beakers and a single small petri dish with a soft amber-tinted liquid add a subtle laboratory note, kept calm and organic. A single sprig of dried herbs and a few scattered oat-colored grains add texture.

The palette is earthy and refined: oatmeal, soft sage, terracotta, warm amber, and charcoal accents against the muted neutral background. Shadows are soft and diffused, with a gentle highlight on the glass and the glossy reishi cap. The composition leaves generous negative space in the upper right for a headline overlay. Shallow depth of field blurs the edges slightly, while the central mushrooms and capsules stay crisp. The overall feel is modern, clean, and trendy, like a wellness and science magazine cover, with tactile natural textures, minimal styling, and a quiet sense of curiosity and skepticism.

蘑菇胶囊提升 VO2max 14.8%——但其中有个大问题

BY DR. GYMBRO ·

一颗蘑菇胶囊、40 天、VO2max 提升了 14.8%,听起来几乎像是天方夜谭。最新发表在《Antioxidants》上的研究称,50 名年轻男性运动员每天摄入 320 mg 含 β‑葡聚糖的多菌种提取物,最大摄氧量从 46.26 mL/kg/min 上升至 53.12 mL/kg/min。值得注意的是,这项研究没有安慰剂组、也未采用随机化和双盲设计,受试者在实验期间仍保持常规训练。细胞实验虽在大鼠心肌细胞上展示了低氧相关的作用机制,但仅是单一成分的试验,并未直接对应胶囊的整体效果。下面我们来看看这项研究到底说明了什么、不能说明什么,以及哪些人应当持谨慎态度。

A wide, editorial-style still life shot from a slightly elevated angle on a pale oatmeal-colored linen surface in soft, diffused morning light. At the center, a shallow matte ceramic bowl in warm terracotta holds a small mound of fine, golden-tan ashwagandha root powder. Beside it lie a few gnarled, dried ashwagandha roots and a sprig of green leaves with tiny orange-red berries in their papery husks. To the left, a minimalist amber glass supplement bottle sits with a few capsules spilled beside it, label blank and clean. A wooden scoop rests on the surface, dusted with powder.

On the right side of the frame, a pair of sleek, muted sage-green running shoes sits slightly off-center. A folded cream towel and a stainless steel water bottle sit just behind them, with a single brushed-steel kettlebell partly out of focus in the background to hint at strength training without dominating the scene. The running shoes and the botanical elements share equal visual weight, suggesting the endurance theme.

A thin, curved line of scattered powder sweeps across the linen from the bowl toward the shoes, like a gentle path or track. Soft shadows fall to the left, and a warm sunbeam crosses the surface and picks out the texture of the powder and the roots.

The palette is restrained and modern: warm terracotta, sage green, cream, soft gold, and touches of charcoal. The background is a blurred pale plaster wall with a hint of a window shadow. Shallow depth of field, crisp focus on the bowl and roots, and generous negative space in the upper left for a headline. Contemporary wellness magazine aesthetic, calm, natural, tactile, high-end lifestyle photography, no text, no people, no futuristic elements.

印度人参的惊喜:对耐力的帮助超过对力量

BY DR. GYMBRO ·

印度人参常被宣传为提升力量和肌肉的补剂,但最新的系统综述指出它的最佳功效可能在别处。汇总13项随机对照试验(共599名受试者)后,研究者发现它对有氧耐力的提升最为稳固,合并效应量为g = 0.54。力量增长虽呈正向,但不确定,且关于爆发力的数据极其有限。每日摄入500‑600 mg提取物似乎是最合适的剂量区间,但仍存在诸多警示,例如预测区间跨越零点。

Wide landscape editorial photograph of a mountain biker mid-ride on a dusty red-orange singletrack trail in the South African Western Cape, golden hour light raking across the scene. The rider is in sharp focus on the right third of the frame, wearing a weathered cycling kit with a race number plate on the handlebars, dust kicking up from the rear tire. Behind them, rolling hills covered in fynbos shrubland and silhouetted protea plants fade into soft, hazy blue mountains. Warm amber sunlight creates long shadows and a soft rim light around the rider and bike.

In the lower left foreground, slightly out of focus, a small minimalist glass vial and a clear water bottle sit on a flat sun-bleached rock, with a few drops of liquid catching the light. Next to them, a simple matte paper notecard and a pencil suggest data collection, with no legible text. The vial and bottle are clean, understated, and modern, with no branding.

The color palette is earthy and refined: terracotta, ochre, sage green, dusty teal sky, and cream highlights. The composition uses shallow depth of field, a generous negative space in the upper left sky for headline overlay, and subtle film grain. The mood is contemplative, skeptical, and quietly sophisticated, like a feature photograph from a high-end outdoor sports and science magazine. Natural, candid, cinematic, shot on a 50mm lens with soft contrast and muted saturation. No futuristic elements, no glowing effects, no molecular graphics, no text.

Ketone IQ 在 Cape Epic 提升血酮水平,却未带来任何恢复效益

BY DR. GYMBRO ·

在为期八天的 Cape Epic 中,骑手每天饮用两次 Ketone IQ,使血酮浓度约达 1 mM,但他们的疲劳感、心率、反应时间和恢复情况与安慰剂组毫无差别。该双盲试验在真实比赛环境下评估了 R‑1,3‑丁二醇,而非实验室条件。作者指出,轻微的酮症并未带来实际效益,并提醒不要把丁二醇与酮酯混为一谈。由于仅有 18 名骑手参与,研究规模有限,但对考虑高价酮饮料用于恢复的任何人都是一次警示。

A cyclist in mid-ride, photographed from a low three-quarter side angle on a quiet country road at golden hour, wearing a matte navy jersey and a white helmet, with soft warm light catching the sweat on his forearms. His expression is calm and focused. The road bends gently through rolling green fields, and the background is softly blurred with creamy bokeh.

In the foreground on the left, a styled flat-lay-inspired still life sits on a weathered wooden surface and blends into the scene. It includes two clear water bottles with pale citrus-tinted liquid, a few torn energy gel packets in muted coral and sage, and a small pile of dried apricots and sliced banana. A handful of glossy orange slices adds a bright accent. The shallow depth of field keeps the cyclist sharp in the middle distance while the foreground items are gently softened.

The color palette is warm and editorial: soft peach, muted terracotta, sage green, cream, and deep navy. The light is natural and golden, with long, gentle shadows and a slight film-grain texture, like a high-end lifestyle or sports-science magazine spread. The composition follows the rule of thirds, with the cyclist on the right third and open negative space in the upper left, suitable for headline overlay.

The mood is energetic yet thoughtful, clean and modern, and the photograph feels authentic rather than staged. There are no logos, no readable text, and no futuristic or sci-fi elements. The overall look is crisp, airy, and refined, in the style of a contemporary health and performance journal cover.

每小时100克碳水让骑手更快——糖原并非关键因素

BY COACH RYAN ·

在一次持续四小时的高强度骑行实验中,每小时摄入100克碳水的骑手比摄入60克的骑手功率下降更少。令人惊讶的是,两组骑手的肌肉糖原储备几乎相同。该随机、双盲、交叉设计的研究提示,提升耐久性能的因素可能超出单纯的糖原保存。本文将解析实验数据、1:0.8 葡萄糖‑果糖配比以及实际应用要点,并说明哪些人群暂不适合采用此方案。

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 ·

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。

A wide, landscape editorial photograph with soft natural morning light. In the foreground, a rustic matte ceramic bowl rests on a pale oak wooden table, filled with vivid deep-green spirulina powder heaped in a gentle mound. A small wooden spoon dusted with the powder lies beside it, and a few scattered green flecks dust the surface. Next to the bowl sits a clear glass of water with a swirl of emerald green just blending in, catching sunlight and casting soft green-tinted shadows.

In the middle ground, slightly out of focus, a pair of worn running shoes in muted sage and cream tones sits on the edge of the table, laces loosely undone. A simple analog stopwatch with a clean white face lies beside them, its hands frozen at a moment suggesting a close finish. A folded linen towel in warm oatmeal tone drapes casually nearby.

The background is a softly blurred outdoor setting seen through a large window: a quiet tree-lined running path at dawn, with golden-hazy light, dewy greenery, and a faint mist. The color palette is calm and modern: deep emerald, sage, cream, warm wood, and touches of soft gold. The composition leaves generous negative space on the right side for headline text, with a shallow depth of field, crisp detail on the powder texture, and a clean, minimalist, lifestyle-magazine aesthetic. Subtle film-like grain, natural shadows, and a fresh, healthy, energetic mood. No people, no text, no logos.

在为期四周的螺旋藻补充实验中,跑者在两小时高强度跑步后,极限冲刺时间延长约32%,约相当于 39 秒。研究还发现脂肪氧化提升 10.9%,且抗氧化剂谷胱甘肽水平上升。但仅有九名男性参与,样本规模有限,结果仍需更大规模研究验证。

A landscape editorial photograph in soft natural morning light. In the foreground on a rustic light oak table, a small cluster of fresh Rhodiola rosea plants with thick succulent blue-green leaves and tiny golden-yellow flower clusters rests beside a few dried, knobby amber-brown rhizome pieces. A matte ceramic cup of pale golden herbal tea sits beside them, with a thin curl of steam and a small linen cloth. The plants and roots are sharp, with fine texture and dewy highlights.

In the softly blurred background, a lean cyclist in a fitted charcoal jersey stands beside a road bike on a quiet country lane at sunrise. Rolling green hills fade into pale mist behind them, and warm light rims the rider's shoulders. The cyclist tightens a glove, calm and focused, in a pre-ride moment of preparation. A water bottle is mounted on the bike frame, and a simple analog stopwatch with a brushed metal casing lies on the table near the herbs, hinting at timed effort.

The palette is muted and modern: sage green, warm cream, soft gold, and slate gray, with gentle peach tones from the sunrise. Shallow depth of field, a clean, airy composition with generous negative space on the right third for headline text, and subtle film grain. The mood is calm, health-conscious, and quietly athletic, like a premium wellness and sports science magazine cover. No text, no logos, no futuristic elements.

BY DR. GYMBRO ·

一项 2013 年的交叉实验发现,单剂量 3 mg/kg 的红景天在 6 英里自行车计时赛前 1 小时服用,可把完成时间从 25.8 分钟缩短至 25.4 分钟。热身心率从 140 bpm 降至 136 bpm,主观用力感从 6.6 降至 6.0。提升幅度约 1.5%,且仅基于 18 名受试者,仍称不上奇迹。尽管如此,降低对努力感知的角度让它成为耐力运动员的一个有趣的无咖啡因选项。以下是数据的实际意义以及如何理智尝试。

A wide, editorial-style flat lay photographed from above on a pale, warm-gray stone surface lit by soft natural window light. On the left, a matte white supplement sachet and a small frosted glass jar of off-white probiotic powder sit beside a wooden scoop dusted with fine granules. In the center, a modern minimalist stopwatch with a brushed silver case and crisp white face rests on a folded slate-blue running towel, its hands frozen just past the half-minute mark. On the right, a pair of sleek running shoes in cream and sage green are angled diagonally, with a few strands of laces trailing across the surface. Scattered around the arrangement are fresh, natural gut-health cues: a halved kefir-colored ceramic bowl of creamy yogurt with a drizzle of honey, a few sprigs of fresh mint, sliced green apple, and a handful of raw oats. A small glass of water with delicate condensation catches a soft highlight in the background. The color palette is calm and refined: sage green, cream, soft slate blue, and touches of warm honey gold against the neutral stone. Shadows are long and gentle, creating depth and a quiet, premium wellness-journal mood. The shallow depth of field softly blurs the edges, leaving the stopwatch and probiotic jar in crisp focus. Negative space on the upper right of the composition leaves room for a headline overlay.

咖啡因+辣椒素在10公里赛中优于安慰剂,单独使用辣椒素无效

BY COACH RYAN ·

在一项交叉实验中,只有咖啡因与辣椒素的组合在10公里跑中显著优于安慰剂,而单独服用辣椒素没有任何效益。提升主要来源于咖啡因本身,未见二者的协同作用。对体重75 kg的跑者而言,6 mg/kg的咖啡因相当于约450 mg,约相当于四到五杯咖啡的摄入量。咖啡因组出现失眠、焦虑、头痛和心动过速等不良反应,使用前需慎重。

A cyclist's legs mid-pedal on a stationary road bike, shot in a bright, airy, minimalist studio with a soft warm-grey backdrop. In the foreground on a pale oak table sits a small ceramic dish holding four deep coral-red softgel capsules, with a few translucent droplets of red-orange oil glistening beside them. Beside the dish is a sprig of dried red microalgae-toned seaweed and a halved wild salmon fillet, its coral flesh echoing the capsule color. Behind the table, slightly out of focus, a cyclist in a fitted charcoal jersey and matte black shorts rides a bike on an indoor trainer. Only the torso and legs are visible, with no face. A white towel hangs over the handlebars and a clear water bottle catches the light.

Soft diffused morning light streams from a large window on the left, creating long gentle shadows and a subtle golden-hour glow on the skin and the glossy capsules. The palette is restrained and editorial: warm cream, sand, soft grey and charcoal, with vivid coral-red as the single accent color. A minimalist analog stopwatch with a clean white face sits on the table, its hands near the 85-minute mark. A thin, elegant line-graph shape is subtly suggested by a curved strip of red ribbon lying on the table, rising from left to right to hint at the performance gain without any text.

The composition follows the rule of thirds, with the capsules and stopwatch in the lower left and the cyclist's motion-blurred legs sweeping across the right. Shallow depth of field, crisp macro detail on the capsules, and a fine film-like grain. The overall feel is a modern health and science magazine cover: clean, calm, sophisticated, and natural, with negative space in the upper area for a headline. There are no futuristic elements, no glowing effects, no laboratory equipment, and no text or logos. Landscape 16:9 format.

4天虾青素让骑行极限时间从72分钟提升至85分钟——小规模试验

BY DR. GYMBRO ·

在一项小规模的随机对照试验中,受试者连续四天每日摄入28 mg虾青素后,骑行至力竭的时间从约72分钟延长到85分钟,提升幅度约18%。同样的方案还能抑制高强度骑行后肌肉损伤标志物(CK、LDH)和脂质过氧化物(MDA)的升高。炎症指标和燃料利用并未出现显著变化,机制仍不明确。该剂量远高于市面多数软胶囊的含量,且研究仅涉及十位年轻男性。

A wide, editorial still life photographed in soft natural window light on a pale oatmeal-colored linen surface. At the center sits a small, rustic ceramic dish holding a handful of dried golden-orange Rhodiola rosea root pieces and a few fresh, fleshy green-gray succulent rosettes with rosy-pink tips. Beside it, a single matte amber glass capsule bottle lies on its side, with two cream-colored capsules spilling out. On the left, a minimalist analog stopwatch with a brushed brass case rests slightly out of focus, its hands suggesting a duration just past the quarter-hour mark. On the right, a worn, chalk-dusted steel kettlebell handle and a folded charcoal gym towel fill the negative space, hinting at lifting without showing a full gym scene.

In the foreground, a neat row of seven tiny ceramic pill cups arranged in a gentle diagonal line, the first cup holding one capsule and the rest sitting empty, as a quiet visual metaphor for a single dose versus daily dosing. A sprig of dried alpine moss and a few small speckled pebbles add organic texture. The background is a softly blurred warm-gray plaster wall with a gentle gradient shadow cast by a window frame, creating diagonal light stripes across the scene.

The palette is muted and earthy: sage green, terracotta, warm cream, brushed brass, and soft charcoal, with one subtle pop of coral from the Rhodiola tips. Shallow depth of field, crisp focus on the root and capsules, and fine film-like grain. The composition leaves generous clean negative space in the upper left for a headline overlay. The overall feel is a modern wellness and science journal: calm, tactile, minimal, and sophisticated, with a slightly moody, high-end magazine look.
