Document Summary

Flexibility: ability to move a joint smoothly through a full rom, having good flexibility will reduce your chances of injury. Using high kicks and functionality to increase flexibility in the muscles) Factors that limit flexibility: bony structures we cant really change this though, tissue approximation, excessive fat, muscle and tendon lengths most responsible for rom. You can take advantage of the elasticity and plasticity of the muscle and tendon lengths: connective tissue if tissue is mobilized for too long, it will lose its elasticity, scarring and contractures, skin. In sports, extremities must be able to move through unrestricted rom to reduce lilkelihood of injury and increase performance: muscles must be elastic for additional activity during the activity, must have elasticity for additional stretch encountered during activity. Joints are capable of multiple movements: antagonist is involved in stretch and is involved with resisting movement, know what agonist is.
