A warm, softly lit modern home gym or sunlit studio, photographed in a clean editorial style. In the center-right of the frame, a silver-haired woman in her mid-60s with a calm, confident expression grips a matte black kettlebell at hip height. She wears a fitted sage-green athletic top and charcoal leggings. Her forearms and shoulders show lean, defined strength rather than bulk. Beside her, slightly out of focus, a man in his late 60s with short white hair and a trim beard performs a controlled bodyweight plank on a pale oak floor.

In the foreground on the left, a minimalist wooden tray holds two small ceramic bowls. One contains fine white powder and the other holds a few cream-colored capsules. Next to them sit a glass of water with a lemon slice and a folded linen towel. A subtle scatter of powder dusts the tray. The foreground is shot with shallow depth of field and a creamy bokeh falloff.

Behind them, tall windows pour in golden morning light, with long soft shadows across the floor. A potted fiddle-leaf fig and a stacked set of pastel-toned dumbbells on a low wooden shelf add texture. The wall is warm off-white plaster with a hint of terracotta in the corner.

The palette is muted and modern: sage green, warm cream, soft terracotta, natural oak, and charcoal, with gentle highlights. The mood is quietly optimistic, focused, and grounded, suggesting strength, vitality, and measured scientific curiosity. The composition leaves clean negative space in the upper-left for a headline overlay. The look is a high-end wellness magazine cover with natural film-like grain, soft contrast, and crisp detail on the hands and kettlebell. There is no text, no logos, and no futuristic elements, only authentic, aspirational realism.

クレアチン+HMBで60代以上が6週間で筋力向上、筋肉サイズはほとんど変化なし

BY DR. GYMBRO ·

60歳以上の活発な高齢者30名を対象にした二重盲検クロスオーバー試験で、クレアチン+HMB併用により6週間で脚・背中・腕の筋力が有意に向上した。一方、筋肉量の増減はほとんど見られなかった。回帰分析からは、筋力向上が筋肉サイズとはほぼ独立した神経筋的効果に起因すると示唆された。試験期間が短く、被験者数が少ない上に体組成はBIAで測定されたという制約がある。本稿では、研究結果の概要と限界、実際に活用する際のポイントを解説する。

A wide, landscape editorial photograph with a modern wellness-journal feel. 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。
