What technique involves holding a stretch for 10 seconds and then performing an isometric contraction?

1. myofascial release

2. static stretching

3. proprioceptive neuromuscular facilitation

4. active isolated stretching

The correct answer is: proprioceptive neuromuscular facilitation

The technique that involves holding a stretch for 10 seconds followed by performing an isometric contraction is indeed proprioceptive neuromuscular facilitation (PNF). PNF is a popular stretching method that aims to enhance both active and passive range of motion. The process typically includes three stages: the individual stretches a muscle (holding this stretch), then engages in an isometric contraction of that same muscle (meaning the muscle tightens without changing its length), and finally, the muscle is able to stretch further as a result of the contraction. This method not only encourages a greater range of motion but also helps in neuromuscular reeducation, making it an effective tool in both rehabilitation and athletic training. The alternating contraction and relaxation of muscles utilized in PNF can lead to increased flexibility and strength, appealing to many individuals looking to improve their physical performance or recover from injury. In contrast, myofascial release focuses on manipulating the fascia to relieve tension, static stretching involves holding a stretch without further contraction, and active isolated stretching method involves holding a stretch for a short duration followed by quickly releasing it, typically using an active muscle contraction. Each of these techniques has its unique applications and benefits but does not specifically incorporate the both stretching and isometric contraction
