Creatina Antes ou Depois do Seu Treino? Um Pequeno Estudo Dá Vantagem ao Pós‑Treino

BY DR. GYMBRO ·

Você deve tomar creatina antes ou depois de treinar? Um estudo de 2013 com 19 fisiculturistas masculinos mostrou que a dose pós‑treino teve uma leve vantagem sobre a dose pré‑treino em massa magra, massa gorda e supino. Contudo, o teste estatístico formal não encontrou diferença significativa entre os grupos, e os autores usaram a cautelosa inferência de “possivelmente mais benéfico”. Veja o que os dados realmente dizem, por que o tamanho da amostra importa e como aplicar as conclusões com uma rotina simples de 5 g diários.
A landscape, editorial-style flat lay photographed from above on a pale oak gym bench or a matte light-gray concrete surface. On the left side, a clear glass of water sits next to a small matte white ceramic bowl of fine white creatine powder, with a wooden scoop resting beside it and a few loose grains scattered naturally on the surface. In the center, a modern analog wall-style clock face is replaced by a simple minimalist stopwatch in brushed steel, its hands paused, subtly suggesting timing without any text or numbers emphasized. On the right, a neatly folded charcoal gym towel and a single chalk-dusted dumbbell handle enter the frame at the edge, with a faint dusting of white chalk on the wood. A small linen notebook with a pencil rests slightly off-center, its pages blank, hinting at data and study without any readable writing. The color palette is soft and restrained: warm cream, oatmeal, sage green, and muted slate, with one accent of terracotta orange in the pencil or a small ceramic dish. Light comes from a large window at the upper left, casting long, gentle diagonal shadows and a soft highlight across the glass of water, creating delicate caustic reflections on the surface. The depth of field is shallow, with the creatine bowl and scoop in crisp focus and the edges softly blurred. The composition leaves generous negative space on the upper right for a headline overlay. The overall feel is calm, clean, and contemporary, like a wellness and science journal's cover image, with natural textures, subtle film grain, and a refined, premium magazine look. No people, no logos, no text, and no futuristic elements.

Creatina antes ou depois do treino? Um pequeno estudo indica vantagem ao pós‑treino

BY DR. GYMBRO ·

Deve‑se tomar creatina antes ou depois do levantamento? Um estudo de 2013 com 19 fisiculturistas mostrou que a dose pós‑treino ficou um pouco à frente nos ganhos de massa magra, redução de gordura e no supino. Contudo, a análise estatística formal não encontrou diferença significativa entre os grupos, e os autores apenas sugeriram cautelosamente que pode ser “possivelmente mais benéfico”. Veja o que os dados realmente dizem, por que o tamanho da amostra importa e como aplicar a descoberta com uma rotina simples de 5 g por dia.
A wide, editorial-style still life photographed on a pale limestone countertop in soft morning window light. At the center sits a matte white scoop of fine white powder resting beside a frosted glass tumbler of cloudy, pale pink-orange water, with a few watermelon slices and a halved wedge showing glossy coral flesh and thin green rind, a nod to citrulline's natural source. To the left, a neatly folded charcoal gym towel and a brushed steel dumbbell rest at the edge of the frame, slightly out of focus. To the right, a minimalist open notebook with a few hand-drawn tally marks and a simple line graph sketched in black ink rises toward the right edge, next to a slim mechanical pencil and a small analog stopwatch with a clean white face. A few loose grains of powder are scattered across the stone, catching the light. Soft diagonal shadows fall across the surface from a nearby window, and a gentle sage-green wall in the background adds calm contrast. The palette is warm cream, watermelon coral, sage green, and soft graphite gray, with plenty of negative space on the upper left for headline overlay. Shallow depth of field, crisp focus on the powder scoop and watermelon, subtle film grain, natural tones, and a clean, modern wellness-journal aesthetic. Shot at eye level with a slight downward angle, like a contemporary health and science magazine cover. No text, no logos, no people.

8 g de Citrulina Malato = 53 % Mais Repetições e 40 % Menos Dor Muscular? O Que o Estudo Revela

BY DR. GYMBRO ·

Um ensaio cruzado de 2010 constatou que 8 g de citrulina malato foram associados a cerca de 53 % a mais de repetições no supino na última série avaliada e aproximadamente 40 % menos de dor muscular 24 h e 48 h depois. O detalhe importante é que o maior ganho de repetições apareceu apenas nas fases finais da sessão, quando a fadiga já estava instalada. A seguir, explicamos o que realmente foi testado, como usar a dose e o timing de forma sensata, quem pode se beneficiar e por que a taxa de 14,63 % de desconforto gastrointestinal e as limitações do estudo merecem atenção.
A wide editorial still life on a pale, warm-gray stone surface lit by soft morning window light from the left. In the foreground, a rustic ceramic bowl in matte oatmeal glaze holds dried ashwagandha roots, pale tan and gnarled, with a few scattered beside it. A small wooden scoop dusted with fine golden-beige powder rests next to the bowl. Behind them, a few olive-green ashwagandha sprigs with small orange-red berries in papery husks arc across the frame, adding a quiet pop of color. Midground right: a matte black chalk-dusted dumbbell handle and a single brushed-steel weight plate lean casually against a linen-textured backdrop in muted sage. A folded cream cotton towel and a slim notebook with a pencil suggest a training log. The notebook is open to blank, softly lined pages with no legible text. The background fades into a gentle blur of neutral beige and soft terracotta tones, with a hint of a plant shadow cast across the wall in dappled light. Fine dust and powder particles float in the light beams, giving a tactile, organic feel. The composition follows the rule of thirds: botanical elements on the left and center, gym elements on the right, and negative space in the upper right for headline overlay. Shallow depth of field, crisp focus on the roots and powder, creamy bokeh behind. Color palette: sage green, warm sand, terracotta, charcoal black, and a touch of burnt orange. The mood is calm, modern, and trustworthy, like a premium wellness and science magazine. Photographed on a 50mm lens, natural grain, subtle film-like contrast, clean minimalist styling, high-end editorial photography.

A Erva Milenar que Superou o Placebo em um Estudo de 8 Semanas: Força, Massa Muscular e Testosterona

BY DR. GYMBRO ·

Será que uma raiz ayurvédica de séculos atrás realmente supera um placebo? Em um ensaio randomizado de 8 semanas com 57 iniciantes em musculação, os homens que tomaram 300 mg de extrato de ashwagandha duas vezes ao dia ganharam mais força no supino, maior volume nos braços e no peito e apresentaram um aumento mais acentuado de testosterona que o grupo placebo. Eles também perderam mais gordura corporal. O problema é que o estudo foi pequeno, curto e limitado a homens iniciantes. Veja o que os dados revelam, como foi a dosagem, quem pode se beneficiar e por que é preciso manter o ceticismo.
A wide, editorial flat-lay photograph shot from directly above on a pale warm-gray stone countertop, lit by soft natural morning window light with gentle diagonal shadows. On the left, a neatly arranged cluster of whole-food protein sources: two seared chicken breast slices with a golden crust, a small ceramic bowl of creamy Greek yogurt topped with blueberries, three halved soft-boiled eggs with jammy orange yolks, a handful of raw almonds, and a small pile of dried lentils scattered on a linen napkin. At the center, a matte white shaker bottle and a wooden scoop resting in a pile of fine vanilla-colored protein powder, a few grains dusted artfully across the surface. On the right, a minimalist kitchen scale in matte black displaying a portion of food, next to an open notebook with a hand-drawn curve that rises steeply and then flattens into a plateau, drawn in a deep terracotta ink pen, with a small dot marking the bend. A brass pen lies beside the notebook. A single dumbbell with a brushed steel finish sits partially in frame at the upper right corner, grounding the fitness theme without feeling gym-like. Color palette: warm cream, sage green, terracotta, soft charcoal, and butter yellow accents, with generous negative space along the top edge for title overlay. Shallow depth of field, crisp textures, subtle film grain, modern lifestyle magazine aesthetic, clean and calm composition, 16:9 landscape.
