Types of flexibility

Passive Flexibility

The measure of ROM in the absence of active contraction.

Static Flexibility

This relates to ROM about a joint with no emphasis on speed and is controlled passive movement taken to the point of resistance.

Ballistic Flexibility

This refers to the ability to use range of movement with an explosive speed, facilitating the stretch reflex.

Relative Flexibility

This refers to the body seeking the path of least resistance during functional movement patterns. This type of flexibility can result in dysfunction and pain.

Active Flexibility

The measure of ROM in the presence of active contraction.

Dynamic Flexibility

This refers to the ability to use a range of joint movement to execute physical activity at either normal or rapid speed.

Functional Flexibility

This refers to the ability to possess sufficient dynamic and ballistic flexibility in order to perform any movement necessary for a specific activity or sport. Proper muscular strength is a crucial component.

PNF (Proprioceptive Neuromuscular Facilitation) is a stretching method used to enhance range of motion (ROM) and flexibility. It works by extending muscle length and improving neuromuscular efficiency, effectively increasing ROM for both trained and untrained individuals.
