Identify the set of exercises shown below. Explain any four advantages it offers to a sportsperson.

The set of exercises shown represents dynamic stretching (or dynamic warm-up exercises). Four advantages it offers to a sportsperson are: 1. Increases muscle blood flow and core temperature: Active movement warms up the deep muscle tissues, increasing oxygen delivery and metabolic activity. 2. Improves functional range of motion and flexibility: Moving through dynamic ranges of motion prepares joints and muscles for sport-specific movements without diminishing muscular power. 3. Enhances neuromuscular coordination and alertness: Dynamic movements stimulate the nervous system, sharpening reflexes, body awareness, and motor coordination needed during competition. 4. Reduces the risk of sports injuries: Elevating tissue pliability and lubricating joints significantly reduces the incidence of acute muscle pulls, strains, and ligament sprains.
