At the Olympics, athletes strive for victory, compete for medals and try to smash records. Behind those Olympic champions are teams of scientists who study every aspect of a sport, looking for anything that can provide an edge over an opponent. What’s the best lane in which to run a 400m race? What’s the best angle to throw a shot put? What’s the fastest object in sport? In this episode, we uncover the hidden mathematics behind sporting success.

Alok Jha, The Economist’s science and technology editor, interviews Amandine Aftalion, a professor of applied mathematics at the French National Centre of Scientific Research in Paris and the author of “Be a Champion: 40 Facts You Didn't Know About Sports and Science”.
