Which type of stretching involves holding a stretch for an extended period?

Static stretching is characterized by holding a stretch for a prolonged period, typically between 15 to 60 seconds. This type of stretching aims to enhance flexibility and increase the length of muscles and tendons. It involves elongating a muscle group to its furthest point and maintaining that position without movement. This method is effective for promoting muscle relaxation and improving overall range of motion.

In contrast, dynamic stretching involves active movements that stretch the muscles through their full range of motion while mimicking the activity that will follow. It is often performed as part of a warm-up routine. Ballistic stretching utilizes momentum to force a limb beyond its normal range of motion, which can pose a risk of injury if not performed with caution. Ballet stretching may incorporate elements of both static and dynamic stretching but is more specific to dance training and doesn't solely refer to holding a stretch.

Understanding these differences helps clarify why static stretching is the correct answer, as it distinctly requires maintaining a stretch for longer durations to promote flexibility.
