A trio of researchers with Hunter College of the City University of New York has found that despite swimming in vastly different events, competitive swimmers tend to have the same body mass index (BMI). In their paper published in Proceedings of the Royal Society B, Christian Gagnon, Michael Steiper and Herman Pontzer describe their study of elite swimmer morphology and how it compared to elite runner morphology.
Most people have likely recognized the differences in the way elite runners are built—those who run short distances very fast tend to have a lot of muscle. Those who run for very long distances, on the other hand, tend to be very thin. These differences make sense logically—carrying extra muscle or fat in long-distance running would require more energy expenditure. In this new effort, the researchers wondered if the same might be true for swimmers.
Swimmer - Morphology - Researchers - Database - Information
To learn more about elite swimmer morphology, the researchers accessed a publicly available database that holds information for Olympic athletes. For their study, they focused on swimmers competing in the 2012 Summer Olympics in London—and only those who swam freestyle (aka the Australian crawl). For each athlete, they looked at height, weight and in which events they swam. The first two metrics allowed them to calculate a BMI for each athlete, which they used as a means for comparing morphology between swimmers.
The researchers discovered that elite swimmers all tended to have a similar morphology regardless of the events in which they swam. Those who swam short 50-meter...
