A wide, editorial-style flat lay photographed from above on a pale warm-gray stone countertop in soft morning window light. On the left, a simple white ceramic bowl holds fine white baking soda powder, with a vintage wooden spoon resting beside it and a light dusting of powder spilling across the surface. In the center, three identical clear glass tumblers sit in a neat row, each filled with a slightly different cloudy liquid: one almost clear, one milky white, one faintly yellow-tinged. Small kraft paper labels tied to the glasses with twine remain blank. To the right, a minimalist silver stopwatch lies on a folded navy athletic towel, its hands frozen mid-count. A few fresh lemon halves and a single sprig of mint add a bright, natural accent near the citrate glass. A pair of worn but clean women's running shoes sits partly in frame at the upper right corner, laces loose, hinting at an athlete without showing a person. Subtle long shadows fall diagonally across the scene, giving depth and a calm, modern feel. The color palette is muted and cohesive: chalky whites, soft sage green, warm sand, deep navy, and small pops of lemon yellow. Shallow depth of field gently blurs the edges, with crisp focus on the center glasses and stopwatch. Plenty of clean negative space across the top third leaves room for a headline overlay. The overall look is a trendy health and performance journal: clean, tactile, slightly grainy film-like texture, natural and understated, with no text, no logos, and no futuristic elements.

Le bicarbonate de soude bat le citrate de sodium et le combo de 17 secondes

BY DR. GYMBRO ·

On suppose généralement que combiner deux agents tampons est plus efficace qu’un seul. Dans une étude croisée portant sur dix sportives de CrossFit très entraînées, le bicarbonate de soude a réduit le temps du contre‑temps de 6 km de 21,5 s par rapport au placebo, tandis que le citrate de sodium et le mélange n’ont montré aucun avantage. Le bicarbonate a aussi dépassé le citrate de 11,6 s et le combo de 17,2 s, mais au prix d’une gêne gastrique accrue. Voici ce que la recherche a révélé, pourquoi le combo a échoué, et comment l’essayer en toute sécurité.

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 améliore l’endurance cardio, mais pas la force, d’après un nouvel essai de 2026

BY DR. GYMBRO ·

Le HMB est habituellement présenté comme un allié pour conserver la masse musculaire et gagner en force, mais un essai triple‑aveugle récent montre autre chose. Chez 90 hommes, une forte dose personnalisée de HMB liquide (90 mg/kg de masse maigre par jour) combinée à un entraînement fonctionnel à haute intensité a davantage augmenté le VO₂max et les marqueurs de seuil que le placebo. L’effet était le plus marqué chez les pratiquants entraînés, tandis que la force isométrique des jambes est restée inchangée. Voici le calcul de la dose, la comparaison avec la dose standard de 3 g, et les personnes qui pourraient réellement en bénéficier.
