A student conducted research on changes in lung capacity following an 8-week aerobic swimming program. The results showed significant improvements in vital capacity but no change in forced expiratory volume.

Which research question would most logically build upon these findings?

  1. How does swimming compare to cycling for developing respiratory fitness?
  2. Does vital capacity continue to improve beyond 8 weeks of swim training?
  3. Why does vital capacity improve while forced expiratory volume remains unchanged during swim training?
  4. What is the best way to measure lung capacity changes in adolescent swimmers?

\(C\)

Show Worked Solution

Consider Option C: 

  • This option directly addresses the unexpected discrepancy found in the results – that vital capacity improved but forced expiratory volume did not.
  • This question seeks to understand the physiological mechanisms behind this finding, which represents the most logical next step in building knowledge from the original investigation.

Other Options:

  • A is incorrect: Compares different types of training rather than building on the specific findings of this study.
  • B is incorrect: Only focuses on the duration of effects for one parameter without addressing the discrepancy.
  • D is incorrect: Focuses on measurement methodology rather than understanding the physiological response discovered.

\(\Rightarrow C\)
