What this dot point is asking
AQA wants you to describe the phases of a warm-up and a cool-down and explain the benefits of each for performance, injury prevention and recovery.
The warm-up
The benefits of a warm-up:
- Raises muscle temperature so muscles contract and relax faster.
- Increases blood flow and oxygen to the working muscles.
- Increases flexibility and the range of movement at joints.
- Reduces the risk of injury such as muscle strains.
- Prepares the performer mentally and improves focus.
The three phases are deliberately ordered. The pulse-raiser comes first because warm muscles stretch more safely, so the stretching phase that follows can increase the range of movement without risking a tear. The skill-related practice comes last because it rehearses the exact movements of the activity, getting the nervous system and the relevant muscles ready for the patterns they are about to repeat, for example a footballer doing passing and dribbling drills. A warm-up should also be matched to the activity: a sprinter's warm-up builds towards short, fast strides, while a swimmer's takes place in the pool, because specificity applies to preparation as well as to training.
The cool-down
The benefits of a cool-down:
- Gradually lowers the heart rate back to its resting level.
- Removes lactic acid and other waste products from the muscles.
- Prevents blood pooling in the veins, which can cause dizziness.
- Reduces muscle soreness and stiffness (DOMS) in the days after exercise.
- Aids recovery so the performer is ready to train again sooner.
It is worth understanding the physiology behind these benefits, because the higher-mark questions reward the mechanism, not just the outcome. During the warm up, raising muscle temperature makes muscle fibres more elastic and lets them contract and relax more quickly, while increased blood flow widens the vessels supplying the muscles so more oxygen arrives. The pulse-raiser also starts to shift the body towards aerobic energy release, reducing the early reliance on anaerobic work and the lactic acid it produces. During the cool down, keeping the muscles gently active maintains the blood flow that carries away lactic acid and other waste products and brings the oxygen needed to break the lactic acid down (repaying the oxygen debt from EPOC). Stopping suddenly lets blood pool in the veins of the legs because the muscle pump that normally helps return blood to the heart switches off, which can cause light-headedness.

AQA 20193 marksDescribe the three phases of a warm-up and give the purpose of each.Show worked answer →
A Paper 1 recall and understanding item, one mark per phase with its purpose.
Award marks for: a pulse-raiser (light aerobic activity such as jogging) to raise heart rate, muscle temperature and blood flow; stretching to increase the range of movement at the joints and reduce strain risk; and skill-related practice (sport-specific drills) to prepare the neuromuscular system and focus the mind.
Markers want the phase named and a matched purpose. A list of three phases with no purposes caps the marks.
AQA 20224 marksExplain how completing a cool-down helps a games player recover after a match.Show worked answer →
An AO2 question rewarding mechanisms linked to recovery.
Award marks for: light exercise keeps the heart rate and blood flow elevated, so the working muscles continue to receive oxygen; this oxygen helps remove the lactic acid built up during anaerobic efforts, repaying the oxygen debt. Gentle activity also prevents blood pooling in the veins, which avoids dizziness.
For full marks add the recovery benefit: this reduces delayed onset muscle soreness (DOMS) and stiffness, so the player can train again sooner.
