A student investigated the effects of a 10-week aerobic training program on resting metabolic rate (RMR) in adolescents. The results showed that while RMR increased significantly for the group overall, there was considerable variation in individual responses.

Propose THREE further research questions that could be explored based on these findings and explain how each question would help understand physiological responses to aerobic training.   (12 marks)

Sample Answer – At least 3 questions including similar detail

  • “Is there a relationship between changes in resting metabolic rate and changes in resting heart rate following aerobic training?” investigates connections between different physiological measurements.
    • This question would help understand whether multiple physiological systems respond similarly to aerobic training or if they change independently, improving our understanding of how the body responds as a whole.
  • “Do males and females show similar changes in resting metabolic rate following the same aerobic training program?” examines potential sex differences in physiological responses.
    • Understanding how biological factors influence physiological responses to the same training stimulus would help explain the variation observed and could inform how different groups might respond to aerobic exercise.
  • “How do changes in resting metabolic rate differ between participants who trained in the morning versus those who trained in the afternoon?” investigates the influence of timing on physiological responses.
    • This question explores whether the body’s natural circadian rhythms affect how it responds to exercise, potentially explaining some of the individual variation observed in the original study.
