研究发现,疲劳的轻重量 形成体力和肌肉,如重重量。 Light weights to fatigue build strength and muscle like heavy weights, study finds.

一项新的研究发现,将较轻重量提升到肌肉疲劳状态会产生与重力提升相似的体力和肌肉增益,对重力是必要的这一观念提出了质疑。 A new study finds that lifting lighter weights to muscle fatigue produces strength and muscle gains similar to heavy lifting, challenging the idea that heavy weights are necessary. 麦克马斯特大学的研究人员对未受过训练的年轻男子进行了研究,他们在10周后看到类似结果,他们以重或轻的重量进行锻炼,直到失败为止。 Researchers at McMaster University studied young, untrained men who performed exercises with either heavy or light weights until failure, seeing comparable results after 10 weeks. 关键因素是努力而非负重，这表明人们可以根据自己的偏好、关节健康或时间选择合适的锻炼计划。 The key factor was effort, not weight load, suggesting people can choose routines that suit their preferences, joint health, or time. 个别结果各不相同,突出反应中的遗传差异。 Individual results varied, highlighting genetic differences in response. 专家说一致性和努力比重量重要,使抵抗训练更容易获得。 Experts say consistency and effort matter more than weight, making resistance training more accessible.
