Skeletal muscles of Body Builders (BB) represent an interesting model to study muscle mass gains in response to high volume resistance training. It is debated whether muscle contractile performance improves in proportion to mass. Here, we aim to assess whether muscle hypertrophy does not occur at the expense of performance.

健美运动员的肌肉纤维是否天生较弱？与老化匹配对照的单纤维比较。

健美运动员 (BB) 的骨骼肌代表了一个有趣的模型，用于研究响应高容量阻力训练的肌肉质量增加。肌肉收缩性能是否与质量成正比存在争议。在这里，我们旨在评估肌肉肥大是否不会以牺牲性能为代价。
