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.

El bicarbonato superó al citrato de sodio y a la combinación en 17 segundos

BY DR. GYMBRO ·

Muchos creen que mezclar varios buffers aporta más beneficios que usar solo uno. En un ensayo cruzado con diez atletas femeninas de CrossFit de alto nivel, el bicarbonato de sodio redujo el tiempo de la prueba de 6 km en 21,5 s respecto al placebo, mientras que el citrato de sodio y la combinación no fueron claramente superiores al mismo. El bicarbonato también superó al citrato por 11,6 s y a la combinación por 17,2 s, aunque provocó más molestias estomacales pre‑ejercicio. A continuación, se muestra lo que encontró el estudio, por qué la combinación falló y cómo probarlo de forma segura.

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.

El HMB mejora la resistencia cardiorrespiratoria, pero no la fuerza, según un nuevo ensayo de 2026

BY DR. GYMBRO ·

El HMB suele promocionarse como conservador de masa muscular y potenciador de fuerza, pero un ensayo triple ciego encontró lo contrario. En 90 hombres, una dosis personalizada alta de HMB ácido libre en líquido (90 mg por kg de masa libre de grasa al día) combinada con entrenamiento funcional de alta intensidad incrementó el VO₂máx y los marcadores de umbral más que el placebo. El efecto fue más pronunciado en atletas entrenados, mientras que la fuerza isométrica de piernas no se modificó. Aquí tienes los cálculos de la dosis, su comparación con los habituales 3 g y quién podría sacarle mayor provecho.
