What type of flexibility training typically involves holding a stretch for a prolonged period?

Static stretching is the type of flexibility training that focuses on holding a stretch for an extended period, usually between 15 to 60 seconds. This method aims to elongate the muscle and improve flexibility by gradually easing into the stretch, allowing the muscle fibers to relax and lengthen. This approach is beneficial for enhancing overall flexibility and can be particularly effective in preventing injury and improving range of motion when performed consistently.

Dynamic stretching, in contrast, involves moving parts of the body through a full range of motion in a controlled manner, which can help warm up the muscles but does not typically involve holding stretches. Ballistic stretching employs bouncing movements to push the body beyond its normal range of motion, which can lead to injuries. Proprioceptive neuromuscular facilitation (PNF) combines passive stretching and isometric contractions to enhance flexibility, but it usually incorporates techniques that involve both stretching and contracting muscles rather than simply holding a stretch. Thus, static stretching stands out as the most straightforward method of holding a stretch for flexibility improvement.
