What type of stretching technique involves stretching the muscles surrounding a joint by repeated movement?

Dynamic stretching is the correct type of stretching technique that involves stretching the muscles surrounding a joint through repeated movement. This technique is characterized by controlled movements and is often performed as part of a warm-up routine before activities or sports. The purpose of dynamic stretching is to increase blood flow to the muscles, improve flexibility, and enhance the range of motion while preparing the body for physical activity.

Dynamic stretching typically includes movements that mimic the activity to be performed, allowing the muscles and joints to work through their full range of motion. Examples include leg swings, arm circles, and walking lunges. This method is effective in activating the muscles and improving functional flexibility since it engages the muscles in a dynamic way rather than holding a position as in static stretching.

In contrast, other stretching techniques serve different purposes. Active stretching involves holding a position using the strength of the agonist muscles, while PNF (Proprioceptive Neuromuscular Facilitation) stretching combines passive stretching and isometric contracting of the target muscle to improve flexibility. Static stretching, on the other hand, involves holding a stretch without movement, which is generally used to improve flexibility and cool down after exercise rather than prepare the body for activity.
