时差N小时 如何判断自己是不是双关节?(下)

（单词翻译）

Connective tissues also form the tendons that join the bones to the muscles.

结缔组织同样也组成了连接肌肉与骨头的肌腱。

Ligaments and tendons usually restrict the movement of the joint¹, but in some people, these normally restrictive tissues can be quite flexible and allow the extra movement we call double-jointed.

韧带与肌腱通常会限制关节的活动，但是对于一些人来说，这些受限的结缔组织非常灵活，可以做出更大范围的活动，也就是我们所称的“双关节”。

Practice can increase a joint's natural flexibility² just the way stretching can increase your muscles' flexibility.

关节的自然柔韧性可以通过锻炼加以改善，就像伸展运动能够加强肌肉的柔韧性一样。

While flexible joints³ are very useful to contortionists, some joints can become so loose that they are unstable⁴.

灵活的关节对柔术演员来说至关重要，但他们的一些关节可能会变得很不稳固。

This allows the bones of the joint to slip out of their sockets⁵ and can be very damaging.

这很容易导致关节脱臼，对身体造成很大的伤害。

Strengthening the muscles around the joint can stabilize⁶ it and still allow you to show off your trick joint at parties.

加强关节周围肌肉的锻炼能够使关节稳固，并且你依然可以在各式派对上一展“灵活”的风采。
