A wide, editorial-style still life photographed in soft natural window light on a pale oak table, styled like a modern wellness journal cover. In the foreground, a pair of worn white boxing hand wraps lies loosely coiled beside a small amber glass jar of probiotic capsules, its lid set to the side and a few cream-colored capsules spilled onto the wood. Next to them sits a tall glass of water with a thin slice of lemon, condensation beading on the surface. A neat bundle of fresh gut-friendly foods is arranged in the midground: a small bowl of plain yogurt with a drizzle of honey, sliced green banana, a few sprigs of fresh herbs, and a halved kiwi with glistening seeds. Behind them, slightly out of focus, a compact digital kitchen scale shows a lowered weight on its display, and a folded gray athletic towel rests beside a pair of black boxing gloves hanging from a hook against a muted sage-green plaster wall. The color palette is calm and sophisticated: sage green, warm oatmeal, soft cream, faint amber highlights, and touches of charcoal. Light streams in from the left, casting long, gentle shadows and a subtle golden glow across the textures of linen, wood, and glass. Shallow depth of field with a creamy bokeh background, crisp detail on the capsules and the hand wraps. Clean negative space on the right third of the frame leaves room for a headline overlay. The mood is fresh, restorative, and athletic, with a minimalist and refined composition, shot as if on a full-frame camera with an 50mm lens, high-end lifestyle magazine photography.

Cortar peso destrói seu intestino: probiótico reduz marcadores de permeabilidade intestinal

BY DR. GYMBRO · 26 de out. de 2026

Cortes de peso rápidos antes de uma luta são famosos por comprometer a digestão, e um novo estudo randomizado indica que um probiótico pode ajudar. Em 24 atletas de combate de elite, quatro semanas de um probiótico esportivo de múltiplas cepas, tomado duas vezes ao dia, reduziram os sintomas gastrointestinais e baixaram os níveis de zonulina, I‑FABP e D‑lactato em comparação ao placebo. O grupo probiótico também apresentou maior SIgA, menor inflamação e mais bactérias produtoras de butirato. O estudo é pequeno, usa um produto multicepas e não traz dados de desempenho; os achados são promissores, mas ainda não definitivos.

A wide, editorial-style still life shot from a slightly elevated angle on a pale oak gym bench, bathed in soft morning window light. In the center sits a matte ceramic cup of black coffee with delicate steam curling upward, flanked by a small white scoop of coffee beans and two identical glass vials, one filled with a few grains of fine powder and one empty, hinting at dose comparison. Next to the cup rests a pair of worn white boxing hand wraps, loosely coiled, and a slim black stopwatch with its face softly visible. In the foreground, a minimalist notebook lies open with blurred handwritten numbers and a simple pen sketch of a bar graph with bars of equal height, subtle and unreadable, suggesting a null result without any legible text. A small brass kitchen scale sits to the side with a few coffee beans on its tray.

In the soft-focus background, a boxing gym interior is visible: a hanging heavy bag in muted charcoal, exposed brick wall painted off-white, and tall windows casting long diagonal light across the floor. The color palette is warm and restrained: cream, sand, espresso brown, soft charcoal, with a single accent of muted terracotta orange in the hand wraps and a faint sage green in the notebook cover. Shallow depth of field with creamy bokeh, fine film grain, and gentle shadows give it a contemporary lifestyle-magazine and wellness-journal feel. The composition leaves generous negative space on the left third for headline overlay. Clean, calm, trendy, and tactile, with natural textures like wood grain, ceramic glaze, and cotton fabric. No people, no text, no futuristic elements.

Café com Baixa Dose de Cafeína Não Proporcionou Nenhum Impulso nos Sprints de Lutadores de Elite

BY DR. GYMBRO · 23 de out. de 2026

Pensou que seu café pré‑treino turbinaría os sprints? Um estudo randomizado, duplo‑cego e crossover com 15 atletas de combate de nível nacional não encontrou benefício de desempenho com doses de cafeína de 1,5 e 3 mg/kg (cerca de 100 e 200 mg para um atleta de 68 kg). Potência máxima, potência média, índice de fadiga e até as estimativas de contribuição dos sistemas energéticos foram semelhantes ao café descafeinado. Contudo, trata‑se de um resultado nulo em um estudo pequeno, não de prova de que a cafeína não funciona, e a maioria dos trabalhos positivos usa cápsulas de 3–6 mg/kg. A seguir explicamos a matemática das doses, as limitações do estudo e o que realmente fazer antes da sua próxima sessão intensa.
