A sunlit, minimalist home gym corner photographed in soft golden morning light, with a young athletic man seated on a wooden bench, leaning forward with his elbows resting on his knees, catching his breath after a hard leg session. He wears a muted sage-green t-shirt and charcoal shorts, his face turned slightly away from the camera, calm and focused. A matte ceramic dish in the foreground holds a few small, translucent golden softgel capsules, with a glass of water beside it catching the light and casting a soft caustic shadow across a pale oak floor. Behind him, a loaded barbell rests on a squat rack, slightly out of focus, and a tall window pours warm sunlight diagonally across the scene, creating long gentle shadows and a hazy glow. A small potted green plant sits on a shelf at the edge of the frame. The color palette is warm and editorial: cream, soft gold, sage green, pale wood, and charcoal accents. Shallow depth of field, with crisp focus on the capsules and glass in the lower third and a creamy bokeh background. The composition leaves generous negative space on the right side for a headline overlay. The mood is clean, modern, and aspirational, like a high-end wellness magazine or a trendy health journal feature. Shot on a 50mm lens, natural light, fine film grain, subtle matte finish, landscape 16:9 framing.

ビタミンDが欠乏していない男性の筋力回復が加速

BY DR. GYMBRO · 2026年10月29日

ビタミンD血中濃度が十分な男性に、1日4,000 IUのビタミンD3を35日間摂取させると、ハードな下半身トレーニング後の筋力回復が約8 ％速くなることが分かりました。ALT・ASTといった筋損傷マーカーの上昇も抑えられましたが、筋肉痛（遅発性筋痛）の改善はみられませんでした。小規模なランダム化比較試験に基づく結果であり、長期的効果や女性への適用はまだ不明です。ビタミンDを回復サポートに使う際は、まず自身の血中濃度を測定し、医師と相談することが重要です。
