Sample Answer
- The chest strap sensor should be calibrated and securely fastened around the participant’s chest before beginning the exercise session to ensure accurate measurement.
- The device should be set to record breath frequency continuously throughout the 20-minute session with data stored automatically at preset intervals (every 30 seconds).
- The participant’s baseline ventilation rate should be recorded during a 2-minute rest period before commencing exercise to establish individual reference values.
- After completing the aerobic session, ventilation rate should continue to be monitored for a 5-minute recovery period to observe how quickly breathing returns to baseline levels.
- All collected data should be transferred to a spreadsheet for analysis, allowing calculation of average rates, maximum rates, and recovery patterns.
- Consistent placement of the chest strap sensor between participants and testing sessions is essential to ensure reliable and comparable data.
