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.

キノコカプセルでVO2maxが14.8%上昇――しかし大きな落とし穴がある

BY DR. GYMBRO ·

キノコのカプセルを40日間摂取し、VO2maxが14.8%上昇したという結果は夢のように聞こえます。『Antioxidants』に掲載された論文では、18〜22歳の男性アスリート50名が1日320 mgのベータグルカン豊富なマルチキノコ抽出物を摂取し、VO2maxが46.26 → 53.12 mL/kg/minへ上がったと報告されています。ただし、プラセボ群がなく、無作為化・二重盲検も行われていない点や、参加者が訓練を継続していたことなど、解釈に注意が必要です。

In the foreground, a clear glass vial of pale amber liquid sits on a matte white stone surface, with a small dropper beside it and a few droplets catching soft light. A slim brushed-steel measuring spoon and a minimalist notebook with handwritten dose calculations in pencil rest nearby. The numbers are blurred and unreadable.

In the softly blurred background, a bright, airy modern gym with large windows and morning light. A fit man in his thirties, in a charcoal athletic shirt, is mid-stride on a treadmill in profile, with a gentle sheen of sweat and a focused expression. Behind him, a wooden plyo box, a kettlebell, and a rope are arranged neatly, suggesting functional training.

The palette is calm and refined: warm cream, soft sage green, muted terracotta, and touches of deep navy. Natural golden side-light makes long, gentle shadows. Shallow depth of field with a crisp foreground and creamy bokeh. Clean composition with negative space on the left third for a title overlay. Premium magazine photography, subtle film grain, realistic textures, no text or logos, and no futuristic or digital elements.

HMBは有酸素フィットネスを向上させ、筋力には影響しない――2026年の新試験

BY DR. GYMBRO ·

HMBは従来、筋肉の保持や筋力向上を目的としたサプリとして販売されてきましたが、最新の三重盲検試験では別の効果が明らかになりました。90名の男性(除脂肪体重1kgあたり90 mgの液体HMB)と高強度機能トレーニング(HIFT)を組み合わせたところ、プラセボ群に比べてVO₂maxや各種閾値指標が有意に向上しました。この効果は特にトレーニング経験者に顕著で、下肢等尺性筋力には変化が見られませんでした。本記事では投与量の算出方法や従来の3 gプロトコルとの違い、そして実際に恩恵を受けられる可能性が高い層について解説します。

On the left, a small matte white ceramic bowl holds fine white arginine powder, with a wooden scoop resting beside it. At the center, two halved oranges and one whole lemon in saturated citrus tones, with a few glossy droplets of water on the cut surfaces, to suggest vitamin C. On the right, three slim amber glass capsule bottles with minimal cream labels and no legible text stand in a loose row, with a few white capsules spilling out. A single chrome dumbbell handle enters the frame from the upper right corner, partly cropped, its cool metallic sheen contrasting with the warm fruit. A sprig of green rosemary and a folded linen napkin in oatmeal beige add texture. Long soft shadows fall to the left. The palette is warm cream, sunny orange, soft yellow, and muted sage, with a few crisp accents of steel gray. The composition is airy and uncluttered, with generous negative space in the upper left for a title overlay. It has a shallow depth of field, a crisp foreground, and a faintly blurred background. The look is clean, contemporary, and wellness-magazine, like a premium health and fitness journal cover, with natural grain, high-end product photography quality, and a calm, fresh, trustworthy mood.

3 g アルギニン+500 mg ビタミンCでテストステロンが26%上昇

BY DR. GYMBRO ·

アルギニンは過大評価された一酸化窒素ブースターとして長らく注目されてきましたが、最新のランダム化比較試験でビタミンCと併用すると効果が出ることが示されました。50名の男性ボディビルダーに、45日間 3 g のアルギニン(1日3回に分割)と 500 mg のビタミンCを投与したところ、プラセボ群と比べて血清テストステロンと VO₂max が有意に上昇し、体脂肪が減少しました。成長ホルモン、コルチゾール、窒素バランスには有意差が認められませんでした。この安価なスタックは注目に値しますが、規模の小さい単独試験の結果に過ぎず、テストステロンが上がったからといって筋肉が増える保証はありません。
