A student wants to investigate how heart rate responds to aerobic training. Which of the following is the most well-structured research question?

  1. "Does exercise affect heart rate?"
  2. "What happens to the body during a 30-minute jog?"
  3. "How does the average heart rate during a 10-minute step test compare between students who regularly participate in aerobic training and those who don't?"
  4. "Why do heart rates increase when we exercise?"

Consider Option C:  “How does the average heart rate during a 10-minute step test compare between students who regularly participate in aerobic training and those who don’t?”

  • Specific about the physiological parameter (heart rate), the exercise protocol (10-minute step test), and comparison groups (regular vs. non-regular aerobic training participants).

Other Options:

  • A is incorrect: Too vague, lacking specificity about the type of exercise and heart rate measurement.
  • B is incorrect: Too broad, covering multiple potential physiological responses without specificity.
  • D is incorrect: Asks “why” which is explanatory rather than investigative for measuring responses.
