운동 전후 크레아틴 섭취, 작은 연구가 운동 후가 조금 더 유리함을 시사

BY DR. GYMBRO ·

크레아틴을 운동 전에 먹을까, 운동 후에 먹을까 하는 고민은 헬스장에서 가장 흔한 질문 중 하나입니다. 2013년 국제스포츠영양학회 저널에 발표된 연구에서는 19명의 남성 보디빌더를 대상으로 사후 섭취가 약간 더 유리하다고 보고했지만, 통계적으로 유의미한 차이는 확인되지 않았습니다. 실제 데이터와 샘플 수의 한계, 그리고 5 g 일일 섭취법을 어떻게 적용할지 함께 살펴보세요.

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.

운동 전·후에 크레아틴? 작은 연구가 포스트‑워크아웃에 약간의 우위를 제시합니다

BY DR. GYMBRO ·

운동 전이나 후에 크레아틴을 섭취해야 할까요? 2013년 19명의 남성 보디빌더를 대상으로 한 연구에서는 포스트‑워크아웃 섭취가 지방량·제지방량·벤치프레스에서 약간 더 큰 향상을 보였지만, 통계적으로 유의미한 차이는 없었습니다. 저자들은 ‘아마도 더 유익할 수 있다’는 조심스러운 결론을 내렸습니다. 여기서는 실제 데이터가 말하는 바와 표본 크기의 중요성, 그리고 하루 5 g을 꾸준히 섭취하는 간단한 방법을 소개합니다.

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 시트룰린 말레이트, 반복 횟수 53 % 증가·근육통 40 % 감소? 연구 결과 분석

BY DR. GYMBRO ·

2010년 교차시험에서 8 g 시트룰린 말레이트를 섭취한 참가자는 마지막 평가 세트에서 벤치프레스 반복 횟수가 약 53 % 늘고, 훈련 후 24·48 시간에 근육통이 약 40 % 감소한 것으로 나타났다. 효과는 특히 세션 말미에 두드러졌으며, 위장 불편감이 14.63 % 발생한 점과 연구 제한점도 함께 살펴보자.

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.

플라시보를 이긴 고대 허브: 8주 리프팅 실험에서 본 근력·근육량·테스토스테론

BY DR. GYMBRO ·

수세기 전 아유르베다에서 사용되던 아슈와간다 뿌리가 플라시보보다 실제 효과가 있을까? 57명의 초보 남성을 대상으로 8주간 무작위 대조 실험을 진행했으며, 하루 두 번 300 mg 추출물을 복용한 그룹이 플라시보군보다 벤치프레스 힘, 팔·가슴 둘레, 테스토스테론 상승폭이 크게 나타났다. 체지방 감소도 더 크게 보고되었지만, 표본이 작고 기간이 짧으며 대상이 초보 남성에 한정된 점을 고려해야 한다.

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.

근육을 최대로 키우려면 단백질은 얼마나 필요할까? 1.6 g/kg 플래토 해설

BY DR. GYMBRO ·

단백질을 파운드당 2 g 이상 섭취해야 근육이 늘어난다는 주장은 오해입니다. 49개 연구와 1,863명의 성인을 분석한 메타‑분석 결과, 근육 성장 효과는 체중 1 kg당 약 1.6 g에서 정점에 이르는 것으로 나타났습니다. 95 % 신뢰구간 상한은 약 2.2 g/kg이며, 이는 무리한 과다 섭취가 아니라 실용적인 범위를 제시합니다. 훈련 경험이 풍부한 사람일수록 보충 효과가 크고, 연령이 높을수록 그 효과는 감소합니다.
