Sample Answer
Similarities:
- Both cause immediate ventilation rate increases above resting levels
- Both maintain elevated rates during recovery to repay oxygen debt
- Both responses meet increased oxygen demands of working muscles
Differences:
- 100 m sprint produces sharp increases to 40-50 breaths per minute
- 5 km run shows gradual increases stabilising at 30-40 breaths per minute
- Sprint ventilation remains elevated longer post-exercise for oxygen debt repayment
- 5 km run maintains consistent ventilation with gradual recovery
- Sprint uses anaerobic systems; 5 km run uses aerobic systems
