Which stretching technique involves contracting and stretching the muscle?

PNF (Proprioceptive Neuromuscular Facilitation) stretching is a technique that combines both contraction and stretching of the muscle. This method typically involves a partner or an assistant who helps facilitate the stretching process. The technique includes a sequence where the muscle is first contracted isometrically (without changing its length) against resistance, followed by a lengthening stretch of the same muscle. This approach takes advantage of the body's neuromuscular system to enhance flexibility and increase the range of motion.

By engaging both contraction and stretching, PNF stretching effectively stimulates the neuromuscular pathways, allowing for a greater degree of muscle elongation afterward compared to other techniques. This makes it particularly beneficial for athletes or individuals looking to improve their overall flexibility and performance.
