Which stretching technique is characterized by muscle contractions followed by relaxation?

Proprioceptive Neuromuscular Facilitation (PNF) is the correct choice because it involves a unique series of muscle contractions followed by relaxation phases, which enhances flexibility. In this technique, an individual typically performs a stretch, then contracts the muscles involved, followed by a period of relaxation where the muscle is then further stretched. This method takes advantage of the body’s neuromuscular responses to improve range of motion more effectively than other stretching techniques.

Dynamic stretching, on the other hand, involves controlled movements that gradually increase the range of motion, while static stretching consists of holding a stretch in a fixed position. Ballistic stretching utilizes momentum to push the body beyond its normal range of motion, which can often lead to injuries. By contrasting these methods, it becomes clear why PNF is distinct and more effective for improving flexibility through its contraction-relaxation approach.
