A wide, editorial-style still life photographed in soft natural window light on a pale oak table, styled like a modern wellness journal cover. In the foreground, a pair of worn white boxing hand wraps lies loosely coiled beside a small amber glass jar of probiotic capsules, its lid set to the side and a few cream-colored capsules spilled onto the wood. Next to them sits a tall glass of water with a thin slice of lemon, condensation beading on the surface. A neat bundle of fresh gut-friendly foods is arranged in the midground: a small bowl of plain yogurt with a drizzle of honey, sliced green banana, a few sprigs of fresh herbs, and a halved kiwi with glistening seeds. Behind them, slightly out of focus, a compact digital kitchen scale shows a lowered weight on its display, and a folded gray athletic towel rests beside a pair of black boxing gloves hanging from a hook against a muted sage-green plaster wall. The color palette is calm and sophisticated: sage green, warm oatmeal, soft cream, faint amber highlights, and touches of charcoal. Light streams in from the left, casting long, gentle shadows and a subtle golden glow across the textures of linen, wood, and glass. Shallow depth of field with a creamy bokeh background, crisp detail on the capsules and the hand wraps. Clean negative space on the right third of the frame leaves room for a headline overlay. The mood is fresh, restorative, and athletic, with a minimalist and refined composition, shot as if on a full-frame camera with an 50mm lens, high-end lifestyle magazine photography.

減量は腸を壊す：プロバイオティクスでリーキーガット指標を低減

BY DR. GYMBRO · 2026年10月26日

急激な減量は消化器系に大きな負担をかけると知られていますが、最新のランダム化比較試験でプロバイオティクスが腸の保護に効果的かもしれないことが示されました。24名のエリート男性格闘選手を対象に、4週間の多株スポーツプロバイオティクス（1日2回摂取）を投与したところ、胃腸症状の軽減とゾヌリン、I‑FABP、D‑ラクト酸といったリーキーガットマーカーの低下が認められました。さらに、SIgAが上昇し炎症が抑えられ、酪酸産生菌が増加しました。サンプル数が少なく、使用した製品は特定できない点やパフォーマンスデータが欠如している点から、結果は期待できるものの決定的ではありません。以下に試験の概要と実践的な活用方法をまとめます。

A wide, editorial-style still life shot from a slightly elevated angle on a pale oak gym bench, bathed in soft morning window light. In the center sits a matte ceramic cup of black coffee with delicate steam curling upward, flanked by a small white scoop of coffee beans and two identical glass vials, one filled with a few grains of fine powder and one empty, hinting at dose comparison. Next to the cup rests a pair of worn white boxing hand wraps, loosely coiled, and a slim black stopwatch with its face softly visible. In the foreground, a minimalist notebook lies open with blurred handwritten numbers and a simple pen sketch of a bar graph with bars of equal height, subtle and unreadable, suggesting a null result without any legible text. A small brass kitchen scale sits to the side with a few coffee beans on its tray.

In the soft-focus background, a boxing gym interior is visible: a hanging heavy bag in muted charcoal, exposed brick wall painted off-white, and tall windows casting long diagonal light across the floor. The color palette is warm and restrained: cream, sand, espresso brown, soft charcoal, with a single accent of muted terracotta orange in the hand wraps and a faint sage green in the notebook cover. Shallow depth of field with creamy bokeh, fine film grain, and gentle shadows give it a contemporary lifestyle-magazine and wellness-journal feel. The composition leaves generous negative space on the left third for headline overlay. Clean, calm, trendy, and tactile, with natural textures like wood grain, ceramic glaze, and cotton fabric. No people, no text, no futuristic elements.

低用量カフェインコーヒーはエリート格闘家のスプリントに何の効果ももたらさなかった

BY DR. GYMBRO · 2026年10月23日

トレーニング前にコーヒーでスプリントが劇的に向上すると考えていませんか？全国レベルの格闘家 15 名を対象にしたランダム化二重盲検クロスオーバー試験では、体重 1 kg 当たり 1.5 ～ 3 mg（68 kg の選手で約 100 ～ 200 mg）の低用量カフェインを含むコーヒーは、最高出力・平均出力・疲労指数はもちろん、エネルギー系統の推定寄与率に至るまでデカフェと変わりませんでした。ただしサンプルが小さい点と、カフェインが全く効果がないことを証明したわけではないことに留意してください。多くの肯定的研究は 3 ～ 6 mg/kg のカプセルを使用しています。本稿では投与量の目安や実践上の注意点、次回ハードセッション前にすべきことを解説します。
