After completing a 6-week aerobic training program investigating heart rate recovery in teenagers, a student found significant improvements in participants' recovery times but noticed that results varied considerably between individuals.

Which of the following represents the most appropriate further research question based on these findings?

  1. Would a 12-week program show greater improvements in heart rate recovery?
  2. How do different exercise intensities affect heart rate recovery improvements?
  3. Why is heart rate recovery a reliable indicator of cardiovascular fitness?
  4. Does heart rate recovery improve at the same rate for all types of aerobic exercise?

Consider Option B: How do different exercise intensities affect heart rate recovery improvements?

  • This option directly addresses the variability in the results.
  • By investigating how different exercise intensities affect heart rate recovery improvements, the student could explore why participants responded differently to the same training program, potentially identifying optimal training zones for different individuals.

Other Options:

  • A is incorrect: Simply extends the duration without addressing the variability in results.
  • C is incorrect: Focuses on validation of the measurement method rather than building on the findings.
  • D is incorrect: Too broad and doesn’t specifically address the individual differences noted in the results.
