Sample Answer
- Collect baseline resting heart rate and ventilation rate before the jog to establish comparison points for aerobic training responses.
- Monitor heart rate continuously during the 30-minute jog using a heart rate monitor to track cardiovascular response patterns and training zones.
- Measure ventilation rate by counting breaths per minute at 5-minute intervals during exercise to assess respiratory system responses.
- Record ratings of perceived exertion (RPE) on a scale of 6-20 every 10 minutes to correlate physiological responses with subjective feelings.
- Track recovery time by measuring how long it takes for heart rate to return to within 10% of resting levels after exercise.
- Note environmental conditions (temperature, humidity) that might influence physiological responses and training adaptations.
- Analyse data by creating line graphs showing heart rate and ventilation rate changes over time, calculating average values for each phase (rest, exercise, recovery).
- Compare results to established aerobic training norms and previous personal results to identify improvements in cardiovascular fitness.
