Sample Answer
- Direct measurement using metabolic carts with masks can provide accurate data but restrict normal breathing patterns, raising ethical concerns about participant comfort and potential anxiety during exercise.
- Indirect estimation methods like heart rate monitoring are less invasive but provide less accurate data, creating an ethical dilemma between participant comfort and scientific validity.
- For adolescent participants, the use of face masks for direct measurement may cause greater psychological discomfort than for adults, requiring additional sensitivity and clear explanation of procedures.
- Researchers must carefully balance the scientific need for accurate physiological data against the ethical principle of minimizing participant discomfort or distress.
- Pilot testing of measurement methods with a small group before full implementation allows researchers to identify unexpected discomforts or anxieties and modify protocols accordingly.
- Providing participants with options between measurement methods where scientifically viable respects their autonomy while still enabling valuable data collection.
