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.

Bicarbonato de sódio supera o citrato de sódio e a combinação em 17 segundos

BY DR. GYMBRO ·

Todo mundo presume que combinar dois buffers traz mais benefício do que usar apenas um. Em um estudo cruzado com dez atletas femininas de CrossFit de elite, o bicarbonato de sódio reduziu o tempo do teste de 6 km em 21,5 s em relação ao placebo, enquanto o citrato de sódio e a combinação não apresentaram vantagem clara. O bicarbonato ainda foi 11,6 s mais rápido que o citrato e 17,2 s mais rápido que a combinação. O ponto negativo foi o incômodo gastrointestinal maior antes do exercício. Veja o que o estudo encontrou, por que a combinação falhou e como testá‑la com segurança.

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 aumentou o condicionamento cardiovascular, mas não a força, em estudo de 2026

BY DR. GYMBRO ·

HMB costuma ser divulgado como aliado para preservar músculo e ganhar força, mas um novo estudo triplo‑cego mostrou outro efeito. Em 90 homens, uma dose personalizada e alta de HMB em forma líquida (90 mg por kg de massa magra por dia), combinada com treinamento funcional de alta intensidade, elevou o VO₂máx e marcadores de limiar mais que o placebo. O benefício foi maior em atletas treinados, enquanto a força isométrica das pernas não mudou. Veja como a dose se compara ao padrão de 3 g e quem realmente pode se beneficiar.
