训练前后服用肌酸？小规模研究显示训练后略有优势

BY DR. GYMBRO ·

应该在举重前还是后服用肌酸？2013 年对 19 名男性健美爱好者的研究发现，训练后服用在瘦体重、脂肪量和卧推力量上略占优势。但统计检验未显示两组差异显著，作者只能保守地提出“可能更有益”。本文解读原始数据、阐明样本量的影响，并给出每日 5 克的简易使用方案。
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.

健身前后服用肌酸？小样本研究显示训练后更有优势

BY DR. GYMBRO ·

应该在举重前还是举重后服用肌酸？一项针对 19 名男性健美爱好者的 2013 年研究发现，训练后服用在瘦体重、脂肪量和卧推上稍微领先于训练前。不过正式的统计检验并未显示两组之间有显著差异，作者只能给出“可能更有益”的谨慎推断。下面我们来看看数据到底怎么说、样本量为何重要，以及如何用每天 5 克的简易方案来应用这些发现。
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克瓜氨酸苹果酸盐能让你多做53%重复次数、酸痛降低40%？研究揭示真相

BY DR. GYMBRO ·

一项2010年的交叉试验显示，单次摄入8克瓜氨酸苹果酸盐可使卧推次数在最后一组提升约53%，并在训练后24至48小时将肌肉酸痛降低约40%。这种效果主要出现在训练后期，当疲劳已积累时。研究仅涉及男性且只测试了卧推这一动作，约15%的受试者出现胃部不适。整体来看，它是高容量、短间歇训练的温和助力，但并非适用于所有人。使用前最好先自行评估是否会产生胃部不适。
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.

古老草药在8周增肌试验中胜过安慰剂：提升力量、肌肉体积及睾酮水平

BY DR. GYMBRO ·

一项为期8周、涉及57名男性初学者的随机对照试验显示，每日两次服用300 mg阿育吠陀根提取物，可在卧推力量、手臂和胸围以及血清睾酮水平上显著优于安慰剂，同时还能降低体脂。但该研究样本量小、周期短，仅针对男性新手，需审慎解读。

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.

BY DR. GYMBRO ·

你是否一直以为每磅体重需要摄入超过 2 克蛋白质才能增肌？对 49 项试验、1863 名成年人的荟萃分析显示，肌肉增益在每日约 1.6 克/公斤时出现平台期。其上限置信区间约为 2.2 克/公斤，为健身者提供了一个实用的范围，而不是随意的大剂量。经训练的举重者从补剂中获益最大，且随年龄增长效应会下降。下面看看这些数字对你的餐盘、摇杯和预算意味着什么。
