What type of stretch is characterized by a slow and controlled approach to improve flexibility?

The type of stretch characterized by a slow and controlled approach to improve flexibility is a static stretch. This method involves holding a position at the point of mild discomfort for an extended period, typically between 15 to 60 seconds. By doing so, muscle fibers are gradually lengthened, which promotes an increase in flexibility and range of motion over time. This is particularly beneficial for enhancing overall flexibility without the risk of injury, as the controlled nature of static stretching allows for a focus on proper tension without rapid movements that could lead to strain.

In contrast, dynamic stretching involves active movements that take joints and muscles through their full range of motion but does not focus on holding a position. Ballistic stretching uses momentum to force a body part beyond its normal range of motion, which can lead to injuries. Active stretching involves contracting one muscle group to stretch the opposing group but is generally less focused on maintaining a steady hold than static stretching. Hence, static stretching is the most suited choice for controlled flexibility improvement.
