Flexibility is the range of movement of the joint of a sports
person.

Active flexibility :- The ability of an individual to do the joint
movement for a longer range without any external help. Active
flexibility is always greater than passive flexibility. Ex. doing
any stretching exercise without external help.
It is two kinds :-
* Static Flexibility :- It is usually required by a sports person
when he remains in static position e.g. Diving, sitting, lying,
etc.
* Dynamic Floexibility :- It is needed for walking and running
its increase by static stretching.

Passive Flexibility :- the ability to do joint movement with a
greater range with an external help of partner. This flexibility
is largely determined by joint structure, stretch ability of the
muscle and ligament. Passive flexibility helps in the
development of active flexibility.
