A wide, editorial-style flat lay photographed from above on a pale warm-gray concrete surface, lit by soft natural window light with gentle shadows. On the left, three small matte ceramic bowls in sage green, soft terracotta, and cream, each holding a different white crystalline powder. The textures vary subtly: fine and powdery, slightly granular, and glittery with tiny crystalline flecks. Beside them rest three minimalist wooden scoops, a few scattered grains catching the light. In the center-right, a worn classic black-and-white soccer ball sits slightly off-frame, partially cropped by the edge, with a pair of muted navy cleats resting nearby, laces loosely draped. A small stopwatch with a brushed-steel finish and a folded sheet of graph paper with a hand-drawn bar chart in soft coral and teal pencil add a subtle sense of data and measurement. A few blades of fresh-cut grass and a sprig of eucalyptus add organic accents. The palette is calm and modern: warm neutrals, sage, terracotta, and muted navy, with one pop of coral. The composition leaves generous negative space in the upper right for headline text. The mood is clean, curious, and trustworthy, like a contemporary health and science journal. Shallow depth of field, crisp focus on the powders, with the soccer elements slightly softer. High-end editorial photography, 16:9 landscape.

La creatina HCl supera al monohidrato en futbolistas: no la deseches todavía

BY DR. GYMBRO ·

Un ensayo aleatorizado con 40 futbolistas demostró que la creatina HCl y el éster etílico generaron mejoras superiores al monohidrato en salto, sprint, agilidad y potencia pico tras apenas cuatro semanas. Todas las formas de creatina superaron al placebo, pero las versiones “de moda” sobresalieron en las pruebas explosivas. Sin embargo, el estudio contó con solo 10 atletas por grupo, no indica la dosis en el resumen y sus resultados chocan con investigaciones previas. Aquí explicamos qué mostró, qué omitió y cómo interpretarlo.

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.
