时差N小时 如何能快速增加肌肉?(上)

You probably know that the way to stronger musclesis a weight or resistance training program,

你可能知道要长肌肉需要合适的重量或阻力训练计划,

but do you know how weight lifting increases strength?

但你知道举重也能长肌肉吗?

One way is by making muscles larger in circumference¹ and hence heavier in mass.

一种方法是通过增加肌肉的周长,从而使得质量变大。

Muscles are composed of cells called muscle fibers².

肌肉是由被称为肌肉纤维的细胞组成。

Strength training increases the size of these muscle fibers.

力量训练会增加这些肌肉纤维的大小。

This form of muscle growth is called hypertrophy.

这种形式的长肌肉称之为过度增长。

Ultimately, muscle fibers hypertrophy by increasing their protein content.

最终,通过增加蛋白质含量肌纤维过度增长。

Strength training, believe it or not, increases the protein content of your muscles by damaging them.

信不信由你, 力量训练会通过破坏它们增加你肌肉的蛋白质含量。

The stress of lifting a challenging weight creates tiny tears in the structural³ proteins inside the muscle.

一项具有挑战性的举重在肌肉内的结构蛋白中产生微小的裂缝。

These tears activate⁴ cells on the outer surface of the muscle called satellite cells.

就是这些裂缝会刺激激活肌肉外表被称为卫星细胞的组织。

Satellite cells multiply and send cells to help repair the damaged areas.

而卫星细胞会进行繁殖并送出细胞帮助修复受损的区域。

1 circumference   

n.圆周，周长，圆周线

参考例句：

• It's a mile round the circumference of the field.运动场周长一英里。
• The diameter and the circumference of a circle correlate.圆的直径与圆周有相互关系。

2 fibers

• Sympathetic fibers are distributed to all regions of the heart. 交感神经纤维分布于心脏的所有部分。

3 structural   

adj.构造的，组织的，建筑（用）的

参考例句：

• The storm caused no structural damage.风暴没有造成建筑结构方面的破坏。
• The North American continent is made up of three great structural entities.北美大陆是由三个构造单元组成的。
