Pushing human performance

What does it take to win an olympic gold medal? Humans are pushing the limits of performance. The difference between a gold and a tin medal can be a tiny percent. In today's ultra competetive events you need every ounce, and the ability to closely monitor an athelete during training can be key. Dr Leif Hanlen is a senior researcher at Australia's IT research body NICTA where they are building devices for real-time evaluation of atheletes. But it's not just about elite sport stars because anybody who wants their health closely monitored will be interested. Then, what do you do with the data? This can be mined for insights into the individual or the population. Leif interviewed by Rod, Arwen and Michael, who also brought his own beautiful music into this show.
