Why the study?
Do elite swimmers have different lung volumes and mechanical lung function compared to elite runners and controls?
Population
24 male subjects: 8 elite swimmers, 8 elite long distance athletes, and 8 control subjects
Comparison
Elite swimming training vs Elite long distance running training and control
Design
Cross-sectional

Larger lung volumes in elite swimmers should not yet change practice; leaves open whether selection or training drives alveolar differences.
Do elite swimmers have different lung volumes and mechanical lung function compared to elite runners and controls?
Elite swimmers possess larger lung volumes and wider chests than runners and controls, likely due to an increased number of alveoli rather than alveolar size or inspiratory muscle strength.
Armour et al. (1993) studied this question.
