Runners at the starting line jog in place, bring their knees to their chests, and swing their legs from side to side. This illustrates which method of stretching?

• A. Static stretching
• B. Dynamic stretching
• C. Ballistic stretching
• D. Proprioceptive neuromuscular facilitation

Answer: (B)

Dynamic stretching involves moving joints through a full range of motion with controlled, continuous movements that simulate the actions of the upcoming activity. The sequence shown—jogging in place, bringing knees to the chest, and swinging the legs side to side—consists of ongoing, active motions designed to warm up and prepare the body for running. This approach increases blood flow, muscle temperature, and mobility without holding a stretch.

Static stretching would involve holding a stretch for a period, which isn’t occurring here. Ballistic stretching uses bouncing and can be more forceful, which isn’t what these movements demonstrate. Proprioceptive neuromuscular facilitation requires specific techniques and often a partner, which isn’t part of this scenario.
