How is dynamic stretching defined?

Dynamic stretching is defined as a form of stretching that involves the active movement of body parts, leading to the stretching of muscles surrounding a joint through repeated motion. This type of stretching typically includes controlled movements that increase range of motion and prepare the muscles for higher-intensity activities. The emphasis is on movement rather than holding a stretch, which distinguishes it from static stretching where muscles are held in a stretched position for an extended duration.

Dynamic stretching is particularly beneficial as a warm-up technique because it increases blood flow, enhances flexibility, and activates the muscles that will be used during physical activity. This preparation helps reduce the risk of injury when engaging in more vigorous exercise.

The other options describe different concepts. Holding a stretch for several seconds pertains to static stretching, which does not involve movement. The mention of heat and massage refers to therapeutic techniques rather than stretching itself. An exercise routine aimed at improving strength is unrelated to stretching techniques and focuses instead on resistance training or muscle building.
