A cyclist in profile, riding a sleek road bike along a quiet coastal road in warm golden-hour light, shot from a low side angle with a shallow depth of field. The rider wears a muted sage-green jersey, black bib shorts, a matte white helmet, and sunglasses. Their face shows calm, focused fatigue, with a faint sheen of sweat on the forearms. One hand is lifted slightly from the handlebars, holding a small, unbranded matte gel packet in soft cream and coral tones, just before opening it. The road curves gently behind them toward a hazy, softly blurred horizon of pale sea and distant hills, with long amber shadows stretching across the asphalt. In the foreground, slightly out of focus, a few gel sachets and a bike bottle rest on a weathered stone wall at the left edge of the frame, adding editorial depth. Fine dust and sunlight glow in the air. The palette is warm and restrained: butter yellow, soft peach, sage, and slate blue, with gentle film-like grain. The composition leaves open negative space in the upper right, a pale gradient sky, for headline overlay. The overall look is a modern, minimalist sports-science magazine photograph: natural, premium, and clean, with realistic textures, cinematic but understated color grading, and no text, logos, or graphics.

Geles de bicarbonato a mitad del recorrido suman 12 W al final de una prueba de ciclismo de 3 horas

BY DR. GYMBRO ·

¿Y si el mejor momento para tomar bicarbonato no es antes de la carrera, sino durante ella? Un nuevo estudio cruzado aleatorio con 11 ciclistas entrenados probó geles de bicarbonato con carbohidratos durante 3 horas de pedaleo. En estado de fatiga, la potencia en una prueba de 12 minutos fue 12 W mayor que con solo carbohidratos, y los síntomas gastrointestinales no fueron diferentes. Sin embargo, los sprints y los esfuerzos de 2 minutos no mostraron ganancias significativas; la muestra fue muy pequeña y los productos provenían de MNSTRY. Esto es lo que revelan los números.
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.

Bicarbonato de sodio + sprints: la dosis que superó al placebo en todas las pruebas

BY DR. GYMBRO ·

Un nuevo ensayo aleatorio en jugadores de baloncesto descubrió que añadir bicarbonato de sodio (bicarbonato de hornear) a cuatro semanas de entrenamiento en intervalos de sprint superó al placebo en salto, sprint, agilidad, distancia Yo‑Yo y potencia Wingate. La dosis más alta (0,45 g/kg) superó a la de 0,30 g/kg en todas las medidas. Esto lo convierte en un suplemento barato y tentador para deportistas de equipos, aunque el estómago puede ser un problema y el estudio es pequeño, corto y solo con hombres. Aquí tienes el cálculo de la dosis, los trucos para evitar molestias gastrointestinales y a quién le puede interesar realmente.
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.
