mobility在体育中的意思是什么，说得具体点，最好能举个例子，大恩不言谢

Mobility 移动性/流动性 /机动性 /可移性
Mobility is the ability to move freely. If your basketball injury causes you to lose mobility in your knee, that means you can’t move it very well.

Mobility often refers to whether you can move
an injured body part, like a joint or a limb, but it can also describe
movement in general. If you have great mobility on the tennis court,
that means you move freely and easily, running down shots with ease.

移动性是自由移动的能力。如果你的篮球运动伤害使你的膝盖丧失了移动功能，那就意味着你的移动性非良好。移动性通常指的是你是否自由移动一个受伤的身体部位，如关节或肢体，但它也可以描述一般的运动。如果您在网球场上有很大的移动性，这意味着你自由轻松地移动，轻松地跑动和出手。
例句：
A knee operation has restricted his mobility;

灵活性；机动性；移动能力
Aerobic exercise keeps your muscles strong, which can help you maintain mobility as you get older.
有氧运动锻炼了肌肉，当你年老时仍能灵活自如。
