What are the 3 types of stretching?

1) Passive Stretching
2) Self-Stretch
3) Dynamic Stretching

How well did you know this?

Not at all

Perfectly

A sustained or intermittent external end range stretch force, applied with overpressure by manual contact. Shortened tissue is elongated by moving a restricted joint just past the available ROM, while the patient is as relaxed as possible.

Passive Stretching

How well did you know this?

Not at all

Perfectly

Any stretching exercise that is carried out independently by a patient after instruction and supervision by a therapist.

Self-Stretch

How well did you know this?

Not at all

Perfectly

Active movements that take joints and muscles through their ROM. They can be functional and mimic the movements of the activity or sport you are about to perform. They can also be a series of movements to get the body ready for a certain exercise.

Dynamic Stretching

How well did you know this?

Not at all

Perfectly

Spring-like response, recoil; the stretched material recovers its pre-tensile dimensions after the applied load is removed.

Elastic Deformation

How well did you know this?

Not at all

Perfectly

Putty-like response; the linear deformation produced by the tensile stress remains even after the applied load is removed, resulting in permanent deformation.

Plastic Deformation

How well did you know this?

Not at all

Perfectly

When a load is applied for an extended period of time, the tissue elongates and does not return to its original length. The amount of deformation depends on the amount of force and the rate at which the force is applied.

Creep

How well did you know this?

Perfectly

A stretch well beyond the normal range of motion of a joint and surrounding soft tissue, placing heavy loads on tendons and ligaments. This causes micro-tearing and inflammation and can lead to hypermobility and degenerative arthritis.
