AsapSCIENCE has partnered with CBC to produce Science Says, a special 20-part series about the science behind the Games. We've got an exclusive first look at one of those videos, about how the bodies of Olympians have changed over the years.
As Mitch and Greg explain, the athletes of the past looked very different from the athletes of today — for example the average professional gymnast has shrunk from 5'3" to 4'9" in 30 years, whereas the average hockey player has grown nearly four inches since the 1920s. And ski jumpers have been steadily decreasing their body weight in order to increase their jump distances. To figure out what's driving those changes, check out the video above.
And for more on the guys behind the hit YouTube series, check out our Q&A with Mitchell Moffit and Gregory Brown.
Head over to the CBC Olympics site for full coverage of the 2014 Winter Olympic Games in Sochi. Television coverage kicks off on February 6 on CBC, and runs until the closing ceremonies on February 23.
