Sample Answer
- A tympanic (ear) thermometer provides quick readings of body temperature at selected intervals without significantly disrupting the exercise but only gives instantaneous measurements rather than continuous monitoring.
- This method is practical and minimally invasive but may be less accurate during exercise due to increased perspiration and environmental factors affecting ear temperature.
OR
- A skin-mounted temperature sensor with wireless connectivity provides continuous temperature monitoring throughout the entire session without requiring the participant to stop exercising.
- This method gives more comprehensive data about temperature fluctuations but requires more expensive equipment and technical expertise to implement correctly.
For both methods
- Environmental temperature should be monitored simultaneously with either method to account for ambient conditions affecting body temperature responses.
- Data collection points should include baseline (pre-exercise), multiple points during exercise (e.g., 10, 20, and 30 minutes), and recovery period to capture the complete temperature response profile.
