In this episode of the podcast, we talk to Marcus Elliott, founder of the Peak Performance Project, or P3. The company uses a slew of data to build better athletes. And we hear from Ryan Warkins, who works at Catapult Sports, a company that tracks athletes with all kinds of sensors. We discuss how to keep star players injury-free and playing at their best. To figure out how to put together a team that works like a well-oiled machine, we talk to Dean Oliver, vice president of data science at TruMedia Networks. He says that numbers have a huge amount of power in sports but that it all comes down to how they’re analyzed. Looking back into the PopSci archives brings up some painful (if hilarious) memories about how we used to train elite players back in the day. Take, for example, these basketball “bumpers” from April 1941, designed to protect your fragile eyeglasses. Or how about this high-tech training exercise from March, 1940? The ways we play (and watch) sports have come a long way in the past 75 years, and they’ll be changing even more going forward. Tune in to find out how.
