What this dot point is asking
Edexcel wants you to explain the purpose and importance of warm-ups and cool-downs, describe the phases of a warm-up, and give the activities included in each.
The purpose of a warm-up
The phases of a warm-up
The order matters: raising the pulse first warms the muscles so that stretching is safer, and skill rehearsal last bridges the gap to the actual activity. A swimmer, for example, might swim easy lengths (pulse raiser), do dynamic shoulder and trunk stretches (mobility), then practise starts and turns (skill rehearsal).
The purpose of a cool-down
A cool-down usually involves a few minutes of light activity (a gentle jog or walk) followed by static stretching held for longer to maintain or improve flexibility. Skipping the cool-down means blood can pool in the muscles and lactic acid clears more slowly, leaving the performer stiffer and sorer.
How a warm-up reduces injury
The injury-prevention benefit is worth explaining in full, because the exam often asks for it. A warm-up raises muscle temperature, and warm muscles and tendons are more elastic, so they stretch further before they tear; cold muscles are stiff and pull or strain more easily. Raising the heart rate gradually also increases blood flow and oxygen to the muscles, getting them ready to work hard, while the mobility phase takes the joints through their range of movement so they are prepared for the sudden, full-range actions of the sport. The skill rehearsal phase grooves the movements and focuses the mind, so the performer is less likely to make a clumsy, injury-risking error early on.
This is why a sprinter who starts cold is far more likely to pull a hamstring than one who has warmed up properly, and why a thorough warm-up is part of every safe session, not an optional extra.

Edexcel 20193 marksDescribe the three phases of a warm-up and give an example activity for each.Show worked answer →
A Component 1 short-answer question. One mark per phase with an example.
Award marks for: a pulse raiser (light continuous activity such as jogging to gradually raise heart rate and body temperature); stretching/mobility (dynamic stretches such as leg swings and arm circles to prepare the muscles and joints); and skill rehearsal (practising movements from the sport, such as dribbling a ball, to prepare mentally and physically).
The mark needs the phase named and a relevant example, in the right order.
Edexcel 20214 marksExplain the importance of a warm-up and a cool-down to a performer, giving two reasons for each.Show worked answer →
A Component 1 application question, marks for benefits of both.
Award marks for: a warm-up gradually raises heart rate and body temperature, increases blood flow and oxygen to the muscles, improves flexibility and range of movement, and reduces the risk of injury and prepares the performer mentally. A cool-down gradually lowers heart rate, helps remove lactic acid and waste products, reduces muscle soreness (DOMS) and aids recovery.
Two genuine reasons for each, linked to performance or recovery, earn full marks.
