A bright, modern editorial photograph of a minimalist athletic studio with pale oak flooring and soft diffused daylight pouring in from tall windows on the left. In the foreground, slightly off-center to the right, a tall glass of deep magenta-crimson beetroot juice sits on a matte white concrete surface, condensation beading on the glass, a few fresh whole beets with leafy stems and one halved beet showing vivid concentric purple rings arranged beside it. Behind them, softly blurred with shallow depth of field, an athlete in neutral-toned athletic wear (charcoal and cream) crouches mid-prep, with slim black blood flow restriction cuff bands wrapped around the upper thighs. A clean wooden plyo box and a simple barbell rack are subtly visible in the background. A thin arc of chalk dust hangs in the air, suggesting a recent jump. The color palette is restrained and trendy: warm off-white, soft sage green, charcoal gray, with the beetroot magenta as the single bold accent. Composition follows a wide 16:9 landscape layout with generous negative space on the left third for title overlay. Lighting is natural, gentle, and slightly golden, with soft shadows and a subtle film-grain texture. The overall feel is a contemporary wellness and sports science magazine cover: clean, calm, sophisticated, tactile, with crisp detail on the juice and beets and a dreamy blur on the athlete.

ビートルートジュース＋BFRトレーニング：疲労時ジャンプで優位は示すも、筋力向上には差が見られず

BY DR. GYMBRO · 2026年11月1日

ビートルートジュースと血流制限（BFR）トレーニングを組み合わせれば筋力が劇的に伸びると考える人も多いでしょう。しかし、最新の二重盲検ランダム化試験では、どちらの群も筋力は向上したものの、統計的に有意な差が出たのは「疲労状態でのカウンタームーブメントジャンプ（CMJ）」だけでした。研究では1日あたり8 mmol（約500 mg）の硝酸塩を摂取させ、1週間のローディング期間と4週間のBFRトレーニングを実施しました。本稿では実験プロトコル、適応できる人と避けるべき人、そして20名規模の研究が示す注意点をまとめます。
