After investigating the effects of a 10-week aerobic training program on respiratory rate during submaximal exercise, a student found that while recovery time improved for all participants, the magnitude of improvement varied considerably across the study group of 15 Year 11 students.

Propose TWO appropriate further research questions that could be explored based on these findings. (4 marks)

Sample Answer – Any TWO of the following or similar with adequate detail.

“How does the type of aerobic training (continuous vs. interval) affect respiratory recovery time improvements?” would investigate whether different training methods produce varying magnitudes of adaptation.
“Is there a relationship between respiratory recovery improvements and changes in other physiological measures such as heart rate recovery or VO₂ max?” would examine connections between different physiological adaptations to determine if they occur proportionally.
“How does initial fitness level affect the magnitude of respiratory adaptations to aerobic training?” would help identify whether pre-training fitness explains the variation in improvement between participants.
“Do respiratory adaptations continue at the same rate beyond 10 weeks of training, or does improvement plateau?” would determine the optimal duration for maximum benefits from the training program.
