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.

중간 구간에 섭취한 Bicarb 젤, 3시간 사이클링 테스트에서 12 W 증가

BY DR. GYMBRO ·

경기 전이 아니라 경기 중에 탄산수소나트(베이킹소다)를 섭취하는 것이 최적일 수도 있다. 11명의 훈련된 사이클리스트를 대상으로 한 무작위 교차 실험에서, 3시간 라이딩 후 12분 타임‑트라이얼 파워가 탄수화물만 섭취했을 때보다 12 W 높게 나타났다. 위장 증상은 두 군 간에 차이가 없었으며, 스프린트와 2분 구간에서는 유의미한 향상이 보이지 않았다. 샘플 규모가 작고 제품은 MNSTRY가 제공했다는 점을 유념해야 한다.

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.

커피 체리 추출물: 200 mg 카페인으로 사이클링 출력 4.6% 상승

BY DR. GYMBRO ·

전체 커피 체리 추출물에서 얻은 200 mg 수준의 저용량 카페인이 훈련된 사이클리스트들의 15분 타임트라이얼에서 작업량을 4.6% 증가시켰습니다. 하지만 근육 글리코겐 재합성 속도가 빨라진다는 흔한 생각은 실험 결과와 맞지 않았습니다. 이 무작위, 이중 맹검, 교차 설계 시험은 12명의 사이클리스트를 대상으로 했으며, 산업계 자금 지원을 받았고 순수 카페인 대비군은 없었습니다. 데이터가 보여주는 점, 보여주지 못하는 점, 그리고 시도해볼 만한 사람은 누구인지 정리했습니다.

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.

케톤 IQ, 케이프 에픽 레이스에서 케톤 수치는 올렸지만 다른 효과는 없었다

BY DR. GYMBRO ·

8일간 진행된 케이프 에픽 레이스에서 라이더들은 케톤 IQ를 하루 두 번 섭취해 혈중 케톤 농도가 약 1 mM에 도달했지만, 피로도·심박수·반응 시간·회복 정도는 위약군과 차이가 없었습니다. 실제 레이스 환경에서 R‑1,3‑부탄디올을 테스트한 이번 이중 맹검 연구는 온화한 케토시스가 회복에 도움을 주지 않으며, 부탄디올을 케톤 에스터와 혼동하면 안 된다고 강조합니다.

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.

시간당 100 g 탄수화물 섭취가 사이클리스트를 더 빠르게 만들었지만—당이 원인은 아니었다

BY COACH RYAN ·

4시간 동안 힘든 라이드 중에 시간당 100 g 탄수화물을 섭취한 라이더는 60 g만 섭취한 사람보다 파워 저하가 적었다. 그런데 두 그룹의 근육 글리코겐 양은 거의 차이가 없었다. 무작위, 이중 맹검, 크로스오버 연구 결과는 글리코겐 보존 이상의 메커니즘이 작용한다는 점을 시사한다. 본문에서는 실험 설계와 1:0.8 비율의 포도당·프럭토스 혼합, 실제 적용 방법을 자세히 살펴보고, 누가 이 전략을 피해야 하는지, 남성만을 대상으로 한 작은 표본이 왜 중요한지도 짚어본다.

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.

Rhodiola Rosea: 자극제 없는 고강도 카디오용 프리‑워크아웃?

BY DR. GYMBRO ·

2013년 교차시험에서 6마일 사이클 타임 트라이얼 전 1시간에 체중 kg당 3 mg의 Rhodiola rosea를 섭취하면 완주 시간이 25.8분에서 25.4분으로 단축되었습니다. 워밍업 시 심박수는 140 bpm에서 136 bpm으로 낮아졌고, 주관적 운동 강도(RPE)는 6.6에서 6.0으로 감소했습니다. 18명만을 대상으로 한 작은 규모의 연구이므로 기적적인 개선이라 보기 어렵지만, ‘노력 인지’가 감소한다는 점에서 카페인 없이도 지구력 향상이 가능하다는 점이 흥미롭습니다. 아래에서 연구 결과와 실용적인 활용법을 정리했습니다.

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.

아스타잔틴 4일 섭취로 사이클링 피로도 제한 시간이 72분에서 85분으로 증가 (소규모 실험)

BY DR. GYMBRO ·

28 mg의 아스타잔틴을 하루에 4일간 섭취하면, 소규모 무작위 대조군 실험에서 사이클링 피로도 제한 시간이 약 72분에서 85분으로 약 18% 늘어났습니다. 같은 프로토콜은 격렬한 75% VO₂max 라이딩 후 근육 손상 지표(CK와 LDH)와 지방산화(MDA) 상승을 억제했습니다. 염증 지표와 연료 사용량은 변하지 않아 메커니즘은 아직 불분명합니다. 복용량은 일반적인 소프트젤보다 훨씬 높으며, 연구 대상은 10명의 젊은 남성뿐이었습니다. 여기서 수치가 보여주고 증거가 끝나는 지점을 정리했습니다.
