We're going for gold on this week's Olympian Naked Scientists, by discovering the sporty science of performance enhancement. We find out how drugs can help boost an athlete's performance, and how the testing labs are hot on their heels! We also explore how altitude training and hi-tech trainers can power athletes past their personal bests. Plus, a stem cell cure for muscular dystrophy, flies with flu and how a rubber Anaconda could generate energy from waves. And in Kitchen Science, we find out how to get the biggest bounce from two balls!
