Title: Explain the basic principles and importance of flexibility training.
Course: Sports Medicine/Athletic Training II (14062-II) > Section: Preventing Injuries

Explanation should include the principles of static stretching, ballistic stretching, and proprioceptive neuromuscular facilitation (PNF). It should include considerations of intensity, duration, and frequency. It should also address the differences between elastic and plastic deformation. It should include the concept that flexibility is important because it increases joint range of motion, facilitates reflex inhibition, and enhances the performance of activities of daily living.

Process/Skill Questions:

- What is static stretching? How is it performed? Why is it important?
- What is ballistic stretching? How is it performed? Why is it important?
- What is PNF stretching? How does PNF take advantage of muscular contraction and relaxation? Of agonist and antagonist relationships? Why is PNF stretching important?
- What is the difference between flexibility and range of motion?
- What is dynamic stretching? When is it more appropriate than static stretching?
