Lung Volume–Dependent Decrease in Projected Frontal Area Contributes to Reducing Active Drag in Front Crawl

ABSTRACT Purpose This study aimed to investigate whether a lung volume–dependent decrease in the projected frontal area (PFA) contributes to reducing active drag in the front crawl. Methods Twelve competitive male swimmers performed a 15-m front crawl at 1.20 m·s −1 while sustaining one of three lun... View More
