elastic elongation
temporary lengthening
plastic lengthening
long term lengthening
what are proprioceptiors
nerves that send information about changes in the muscular and skeletal systems to the nervous system
PNF
Proprioceptive Neuromuscular
Facilitation
Contracting and fatiguing a muscle before stretching it can help allow the muscle to stretch farther
benefits of flexibility

* Improved body position and
strength
* Maintenance of good posture
and balance
* Relaxation
* Improving impaired mobility
