A student conducted research investigating the relationship between heart rate recovery and oxygen saturation levels following a 12-minute Cooper test. The results showed a moderate correlation between faster heart rate recovery and higher oxygen saturation during exercise, but significant individual variation remained unexplained.

Propose THREE further research questions that would logically build on these findings. Explain the purpose and potential value of each question.   (6 marks)

Sample Answer – Other answers are possible.

  • “How does respiratory efficiency affect the relationship between heart rate recovery and oxygen saturation during aerobic exercise?” would explore physiological mechanisms that might explain the correlation found in the original study.
  • This question has value because understanding the underlying mechanisms would allow for more targeted training interventions that specifically enhance the physiological systems most responsible for the observed relationship.
  • “Do individuals with different aerobic training backgrounds (e.g., endurance athletes versus team sport athletes) show different relationships between heart rate recovery and oxygen saturation?” would investigate how training specificity affects these physiological parameters.
  • This question would help coaches and athletes develop more sport-specific training programs that optimise both cardiovascular recovery and oxygen utilisation for their particular needs.
  • “How consistent is the relationship between heart rate recovery and oxygen saturation across different exercise intensities and durations?” would examine whether the moderate correlation holds under various exercise conditions.
  • Understanding intensity-specific relationships would enable more precise training prescriptions for individuals with different fitness goals, from health improvement to competitive performance.
