A warm, sunlit boutique fitness studio in soft morning light, shot in wide landscape composition. In the foreground, a woman in her late 60s with silver-white hair in a loose bun and a relaxed, confident smile holds a light dumbbell mid-curl. She wears a sage green athletic top and charcoal leggings. Her posture is strong and graceful. Beside her, slightly out of focus, a second older woman with short gray hair performs a bodyweight squat. Both are part of a small circuit training class.

On a pale oak wooden bench in the sharp foreground, a minimalist glass tumbler holds a cloudy, pale lemon-colored drink. Next to it is a small ceramic dish of white powder with a tiny wooden scoop, a folded linen towel, and a matte white water bottle. Scattered nearby are a few fresh lemon slices and a sprig of mint for a clean, editorial still-life touch.

The studio has tall arched windows with sheer white curtains, letting in golden diffused light that creates long soft shadows on a light blonde wood floor. Background details include neatly arranged pastel-colored kettlebells and rubber resistance bands in muted terracotta, sand, and sage hanging on a minimalist wall rack. A leafy fiddle-leaf fig plant sits in a terracotta pot in the corner.

The color palette is calm and modern: warm creams, soft sage green, terracotta, muted peach, and gentle gold highlights. Shallow depth of field with a creamy bokeh background, shot as if on a 50mm lens at f/2. Natural film-like grain, subtle warmth, high-end wellness magazine aesthetic, clean negative space on the right side of the frame for title overlay. The mood is optimistic, vital, and grounded, celebrating healthy aging, strength, and community. Photorealistic, editorial lifestyle photography.

必須アミノ酸とレジスタンス運動でミオスタチン抑制：65歳以上女性への効果

BY DR. GYMBRO · 2026年11月1日

65歳以上の健康な女性を対象に、回路式レジスタンストレーニングと1日合計11 gの必須アミノ酸（EAA）を組み合わせた12週間のランダム化比較試験を実施しました。その結果、フォリスタチン／ミオスタチン比が最も改善され、併用群で筋肉量が増加し、炎症マーカーも広範に低下しました。本稿では投与量やトレーニングプロトコル、対象者・除外基準、そして本研究が示せなかった点について詳しく解説します。
