Sample Answer
Initial Recovery:
- Circulatory system maintains elevated blood flow while respiratory rate gradually decreases; muscles begin waste removal
- Heart rate remains elevated to support oxygen delivery while breathing pattern normalises and muscles start repair
- Blood flow redistributes as breathing depth reduces and muscle tension decreases
Mid Recovery:
- Blood flow optimises waste removal while respiratory rate stabilises and muscles replenish energy stores
- Circulatory system supports temperature regulation while breathing efficiency improves and muscle fatigue reduces
- Oxygen-rich blood delivery continues as ventilation normalises and muscle function restores
Late Recovery:
- Heart rate approaches resting as breathing returns to normal and muscles complete recovery
- Blood flow patterns normalise while respiratory efficiency returns and muscle readiness peaks
- Circulatory function balances with steady breathing rate and muscle preparation for next race
