What this dot point is asking
Eduqas wants you to describe the phases of a warm-up, its physical and psychological benefits, the purpose of a cool-down, and how each affects the body's systems and reduces injury.
The warm-up
Benefits of the warm-up
The key idea Eduqas rewards is that a warm-up prepares the body and mind gradually, which both improves performance and reduces the risk of injury.
The cool-down
Tailoring the warm-up to the sport
A good warm-up is specific to the activity that follows. A sprinter's warm-up builds up to fast, explosive strides and practice starts, because the race is anaerobic and powerful; a distance runner's warm-up is gentler and longer, easing the body into sustained aerobic work; a gymnast's warm-up includes plenty of dynamic stretching and mobility, because the routine demands a large range of movement. The skill-specific phase should rehearse the actual movements and skills of the sport (a netball shooter practising shots, a footballer dribbling and passing) so the body and mind are ready for exactly what they will do. The warm-up should also raise arousal to the right level for the task, which links to the sport-psychology topic.
Why each matters for performance and injury
A warm-up before exercise reduces injury and primes the body to perform from the start; a cool-down after exercise speeds recovery and reduces soreness so the performer is ready to train again sooner. Together they bookend a session: prepare, perform, recover. This links closely to the short-term effects of exercise (a warm-up triggers them gradually) and to recovery and EPOC (a cool-down helps repay the oxygen debt and clear lactic acid).
Skipping either has real costs. Without a warm-up, cold muscles are stiff and more likely to strain or tear, the heart is asked to work hard suddenly, and the performer starts slowly and sluggishly. Without a cool-down, lactic acid lingers, blood can pool in the legs causing dizziness, and the muscles are stiffer and more sore in the days that follow. Both are quick to do and make a measurable difference, which is why coaches build them into every session and why Eduqas expects you to justify them.

A Component 1 warm-up question. Marks for the phases and for the benefits explained.
Award marks for the phases: a warm-up usually has three phases - (1) a pulse-raiser (light aerobic activity such as jogging) to gradually raise heart rate and body temperature; (2) stretching and mobility (dynamic stretches and joint mobilisation) to increase the range of movement; (3) skill-specific practice (drills with the ball or equipment) to rehearse the movements of the sport. Physical benefits include: muscles warm up and become more elastic, reducing the risk of strains and tears; heart rate and blood flow increase gradually, delivering more oxygen to the muscles and avoiding sudden strain on the heart; range of movement at the joints increases; and reaction time and coordination improve.
Markers reward the phased structure and benefits linked to performance and injury prevention.

A 3-mark cool-down question. Markers reward the purpose and the physical benefits.
Award marks for: a cool-down is light aerobic activity (a gentle jog or walk) followed by stretching, done at the end of a session. It keeps the heart rate and breathing elevated for a short time so blood keeps circulating, which flushes out lactic acid and other waste from the muscles, speeding recovery and reducing muscle soreness (DOMS). It prevents blood pooling in the limbs (which can cause dizziness if you stop suddenly), and the stretching helps maintain or improve flexibility and reduces stiffness. So a cool-down gradually returns the body to its resting state and aids recovery.
A top answer links the cool-down to lactic-acid removal, preventing blood pooling and reducing soreness.
