健身爱好者:我认为肌酸是最好的补剂,可以帮助我获得更好的锻炼效果。大家都说肌酸对身体有奇效,是健身的必备品。如果你想增肌,就必须服用肌酸。它不仅能增肌,还能提高脑力,改善睡眠不足时的表现,提升情绪和记忆力。关于肌酸的研究数据非常惊人,有50年的数据表明它有效且安全。 Wendy Zuckerman:我将用科学事实对抗健身爱好者,探讨肌酸是否真的能帮助人们拥有大肌肉和聪明的头脑。本期节目将探讨肌酸是否真的能增强肌肉和脑力。 Michelle Dang:肌酸不是类固醇,而是身体从食物中自然产生的物质。人们服用肌酸补充剂是为了获得更多的肌酸。研究表明,肌酸确实能帮助增长实际肌肉,尤其是在老年人中。肌酸可能通过提供更多能量来帮助你增加肌肉,但它不是魔法。肌酸并非对所有人有效,即使有效,也不会让你变得非常强壮。我计划继续尝试肌酸,看看它是否对我有效。 Darryn Willoughby:我认为肌酸不是直接构建肌肉,而是通过在锻炼期间提供额外的能量来起作用。肌酸能将水分带入肌肉细胞,可能使肌肉看起来更大,但这可能只是水分滞留。我通过化学分析发现,服用肌酸的人肌肉中含有更多的肌肉蛋白。肌酸可能帮助你多做两到三个额外的重复动作。你不必担心肌酸会导致脱水。我服用肌酸后会胀气。

Deep Dive

Chapters
This chapter explores the claims surrounding creatine's muscle-building capabilities. It examines scientific studies, including muscle biopsies and analyses of muscle protein growth, to determine the extent to which creatine contributes to muscle growth. The role of water retention versus actual muscle gain is also discussed, along with the perspectives of experts and the implications for athletic performance.
  • Creatine aids in ATP recycling, potentially increasing workout energy and reps.
  • Studies show creatine increases muscle protein content, indicating muscle growth, but the effect is modest.
  • Water retention contributes to increased muscle size, but actual muscle growth also occurs.
  • Creatine is not a banned substance in the Olympics, suggesting its effects on performance are not considered overwhelmingly significant.

Shownotes Transcript

Fitness buffs online can’t stop raving about creatine. They say it is THE supplement to get you shredded in no time — and that it can even boost your brain and memory too. Are they right? We dive into the science of creatine and talk to anatomy Professor Darryn Willoughby, physicist Dr. Ali Gordji-Nejad, and psychology researcher Julia Fabienne Sandkühler.
