Final answer:
Static stretching is used to increase range of motion (ROM). PNF stretching is a more advanced technique that combines passive stretching and isometric contractions.
Step-by-step explanation:
When determining the appropriate program design, static stretching is the method that is typically used to help increase range of motion (ROM).
Static stretching involves holding a stretch for a prolonged period of time, usually around 30 seconds, to gradually lengthen the muscle and increase flexibility. It is often done after a workout or physical activity to help prevent muscle tightness and improve recovery.
On the other hand, PNF stretching is a more advanced stretching technique that involves a combination of passive stretching and isometric contractions. It is commonly used by athletes and individuals seeking to improve flexibility and range of motion.
