Final answer:
PNF stretching specifically trains the stretch receptors in muscles for greater accommodation to being stretched by employing a technique that alternates muscle contraction and relaxation.
Step-by-step explanation:
The type of stretching that trains the stretch receptors of the muscles to become accustomed to being stretched is known as PNF stretching (Proprioceptive Neuromuscular Facilitation). This method involves alternating contraction and relaxation of both the targeted muscle group and its antagonist. The process uses the natural stretch reflex and Golgi tendon organs to allow the muscle to stretch further.
Ballistic stretching involves bouncing movements to push the body beyond its normal range of motion, which can be risky and trigger the stretch reflex more abruptly. On the other hand, static stretching involves holding a stretch for a prolonged period, and this type gently increases flexibility without engaging the stretch reflex excessively. Dynamic stretching includes active movements that gradually increase reach and speed of movement, beneficial for warming up but not specifically designed to work with the body's stretch reflex mechanisms in the same targeted manner as PNF.
