What describes dynamic stretching in relation to joint movements?

Dynamic stretching is characterized by utilizing controlled movements of body parts, which aims to prepare the muscles and joints for physical activity. This type of stretching involves active movements that typically enhance range of motion, increase blood flow, and improve overall muscle performance. Examples include leg swings, arm circles, and walking lunges, all of which are designed to mimic the motions of an activity, thereby effectively warming up the body.

The other options do not accurately represent dynamic stretching. Holding a stretch for an extended duration pertains to static stretching, which contrasts with the movement-based approach of dynamic stretching. Describing dynamic stretching as primarily a relaxation technique is misleading since its purpose is to activate and prepare the body rather than to relax it. Finally, performing stretches with static positions relates to static stretching as well, which also contradicts the active nature of dynamic stretching.
