Sample Answer
Work Interval:
- Nervous system increases motor unit recruitment while respiratory rate rapidly elevates
- Neural signals increase breathing depth as oxygen demand peaks
- Respiratory system responds to neural feedback about exercise intensity
Active Recovery:
- Nervous system moderates motor signals while breathing rate partially decreases
- Neural monitoring adjusts ventilation based on reduced oxygen demand
- Respiratory pattern responds to neural signals for recovery preparation
Next Interval:
- Nervous system reactivates high motor recruitment as breathing rate quickly elevates again
- Neural pathways anticipate oxygen needs as respiratory rate increases
- Respiratory system responds faster through neural preparation
Adaptation:
- Nervous system becomes more efficient at coordinating breathing response
- Neural pathways optimise respiratory patterns for work-recovery cycles
- Both systems improve synchronisation of effort-recovery timing
