Why do performers warm up before and cool down after exercise, and what does each phase do?
The purpose and phases of a warm-up, the physical and psychological benefits of warming up, the purpose and benefits of a cool-down, and how each prepares the body for and recovers it from exercise.
A focused answer to OCR GCSE PE Component 01 on warming up and cooling down: the phases and physical and psychological benefits of a warm-up, the purpose and benefits of a cool-down (including removing lactic acid and reducing stiffness), and how they prepare for and aid recovery from exercise.

What this dot point is asking
OCR wants you to describe the phases of a warm-up, explain the physical and psychological benefits of warming up, and explain the purpose and benefits of a cool-down.
The purpose of a warm-up
A warm-up gradually prepares the body for the demands of exercise. It raises body and muscle temperature, increases heart rate and breathing so more oxygen reaches the muscles, and rehearses the movements of the sport. A good warm-up both improves performance in the session and reduces the risk of injury (linking to the preventing injury topic).
The phases of a warm-up
The benefits of warming up
The purpose and benefits of a cool-down
The cool-down keeps the heart rate and blood flow elevated for a short time, which keeps oxygenated blood flowing through the muscles. This helps to remove waste products such as lactic acid and carbon dioxide, which reduces muscle soreness and stiffness (delayed onset muscle soreness, DOMS) in the following days. The gentle stretching helps return muscles to their resting length and maintains flexibility, and lowering the heart rate gradually helps prevent blood pooling in the limbs (which can cause dizziness or fainting).

A Component 01 item. Award marks for the phases and for two developed benefits.
Phases: a warm-up usually has three phases: (1) a pulse-raiser (light cardiovascular work such as jogging) to gradually increase heart rate and body temperature; (2) stretching/mobility (dynamic stretches and joint mobility) to increase the range of movement; (3) skill-related/sport-specific practice (drills using the movements of the sport) to prepare the body and mind for the activity.
Two benefits (any two, developed): raises muscle temperature so muscles are more elastic and less likely to strain; increases heart rate and blood flow so oxygen reaches the muscles; improves range of movement at the joints; prepares the performer psychologically (focus and readiness); rehearses the skills of the sport.
Markers want the three phases named and two benefits explained, not just listed.

A 3-mark item on recovery.
Award marks for: a cool-down (light aerobic activity then stretching) keeps the heart rate and breathing elevated for a while, which keeps blood flowing through the muscles. This helps remove waste products such as lactic acid and carbon dioxide, reducing muscle soreness and stiffness (delayed onset muscle soreness). Gentle stretching helps return muscles to their resting length and maintain flexibility. The gradual lowering of heart rate also helps prevent blood pooling and dizziness.
Markers reward at least two clear benefits, ideally including the removal of lactic acid and the reduction of muscle soreness.
