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

你或许知道要长肌肉需求适宜的分量或阻力练习方案,

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 circumference and hence heavier in mass.

一种办法是经过添加肌肉的周长,然后使得质量变大。

Muscles are composed of cells called muscle fibers.

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.

力气练习会添加这些肌肉纤维的巨细。

This form of muscle growth is called hypertrophy.

这种方式的长肌肉称之为过度添加。

Ultimately, muscle fibers hypertrophy by increasing their protein content.

终究,经过添加蛋白质含量肌纤维过度添加。

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

信不信由你, 力气练习会经过损坏它们添加你肌肉的蛋白质含量。

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

一项具有挑战性的举重在肌肉内的结构蛋白中发生细小的裂缝。

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

便是这些裂缝会影响激活肌肉表面被称为卫星细胞的安排。

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

而卫星细胞会进行繁衍并送出细胞协助修正受损的区域。
