A student is collecting data on respiratory responses to aerobic training. Which combination of methods would provide the most comprehensive data?

  2. Questionnaire about breathing difficulty and perceived exertion
  3. Oxygen saturation monitor and facial observation
  4. Spirometer and counting breaths per minute

\(D\)

Show Worked Solution
  • D is correct: A spirometer measures volume of air moved while counting breaths measures frequency, providing both quantitative aspects of respiratory response.

Other Options:

  • A is incorrect: These methods measure cardiovascular, not respiratory responses.
  • B is incorrect: Provides subjective data only, lacking objective respiratory measurements.
  • C is incorrect: Oxygen saturation doesn’t directly measure respiratory function and facial observation is subjective.
