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