What is the difference between dynamic and static stretching?

Dynamic stretching involves movement and is typically performed before exercise to help prepare the body for physical activity. This type of stretching increases muscle temperature and elasticity, enhances blood flow, and activates the nervous system, all of which can improve performance during workouts. Movements such as leg swings, arm circles, and walking lunges are examples of dynamic stretches, as they actively take the muscles through their range of motion.

In contrast, static stretching involves holding a muscle at its maximum stretch for a period, usually around 15-60 seconds, without any movement. This technique is generally used after exercise to improve flexibility and cool down the muscles. It is less effective at preparing the body for immediate physical activity because it does not elevate heart rate or increase blood flow to the muscles in the same way that dynamic stretching does.

Therefore, the correct choice highlights the key characteristics of dynamic stretching, emphasizing its focus on movement and its timing relative to exercise.
