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 wide editorial still life on a pale, warm-toned concrete surface in soft morning window light. In the center-left, a shallow matte ceramic bowl holds a small pile of bright red coffee cherries with glossy skins, a few sliced open to reveal pale mucilage and paired green-tan beans. Beside it, a small glass dish of fine, golden-brown powdered extract with a tiny wooden scoop resting on its edge. A sprig of coffee plant leaves, deep green and waxy, arcs across the foreground.

On the right side, slightly out of focus, a sleek road cyclist's handlebar and a matte black water bottle lean against a light plaster wall, suggesting athletic training without showing a person. A minimalist analog stopwatch with a clean white face and thin black hands sits in the mid-ground, angled toward the camera, its hands paused near the fifteen-minute mark. A folded linen cloth in oatmeal beige and a single small espresso cup with a thin crema ring add quiet texture.

The color palette is restrained and modern: cherry red, sage green, cream, soft terracotta, and charcoal accents. Light comes from the left, casting long, gentle shadows with a subtle warm glow and a hint of dust in the air. Shallow depth of field with crisp focus on the cherries and stopwatch, creamy bokeh in the background. Composition leaves open negative space in the upper right for a headline overlay. The overall feel is a clean, trendy health-and-science magazine cover: tactile, natural, minimal, and calm, shot in a 16:9 landscape frame with fine film-like grain and true-to-life tones.

咖啡樱桃提取物:200 mg 咖啡因提升骑行功率 4.6%

BY DR. GYMBRO ·

摄入 200 mg 全咖啡果提取物(含同等量咖啡因)后,受过训练的骑手在 15 分钟计时赛中的功率输出提升约 4.6%。然而,关于该提取物能加速糖原再合成的说法并未得到实验验证。该随机、双盲、交叉设计的试验仅招募 12 名骑手,且由行业赞助,缺少单独咖啡因对照组。以下将阐明数据说明了什么、未说明什么,以及哪些人可能想尝试。

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 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.

红景天:无刺激剂的高强度有氧前摄

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 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.
