A wide, editorial-style still life shot from a slightly elevated angle on a pale, warm-gray concrete surface lit by soft natural window light from the left. In the center foreground, a clear glass of cloudy water sits beside a small white ceramic bowl heaping with fine white baking soda powder, a wooden measuring spoon resting beside it with a light dusting of powder spilling across the surface in a graceful arc. Next to them, a minimalist digital kitchen scale in matte white shows a small portion of powder in a shallow dish. Slightly behind, an orange basketball is partially in frame, its pebbled texture catching the light, resting beside a pair of clean white and coral athletic sneakers with the laces loosely undone. A folded charcoal gray towel and a stainless steel stopwatch lie to the right, the stopwatch face crisp and legible. Three small, neatly arranged piles of white powder on a slate tile in the midground, in ascending sizes, hint at different doses without any text or labels. In the soft-focus background, the faint outline of an indoor basketball court with warm honey-colored hardwood floor and blurred lane lines stretches across the frame, glowing with golden-hour light. The color palette is restrained and modern: warm off-white, soft gray, burnt orange, and touches of sage green from a single sprig of mint or eucalyptus laid near the glass. Shallow depth of field, crisp textures on powder grains and the ball's surface, gentle shadows, subtle film-like grain. Clean negative space in the upper right for headline overlay. The mood is calm, sleek, and contemporary, like a premium health and sports science magazine cover, with a fresh, minimalist composition and no people, no text, and no futuristic elements.

重曹＋スプリント：全項目でプラセボを上回る投与量

BY DR. GYMBRO · 2026年10月27日

新しい無作為化比較試験で、バスケットボール選手が 4 週間のスプリントインターバルトレーニングに重曹（炭酸水素ナトリウム）を併用すると、ジャンプ、スプリント、敏捷性、Yo‑Yo距離、Wingate パワーのすべてでプラセボを上回ることが確認されました。0.45 g/kg の高用量は 0.3 g/kg を全指標で上回り、チームスポーツ選手にとって低コストで有望な追加手段となります。ただし、胃腸への負担が課題であり、サンプルが小規模・短期・男性のみという制約があります。本稿では投与量の計算方法、胃腸不快感への対策、実際に適用できる対象者を解説します。
