Steve Haake has spent much of his career using technology to help elite sports people get better, faster and break records. He has turned his hand to the engineering behind most sports, from studying how golf balls land, to designing new tennis racquets and changing the materials in ice skates. He’s now Professor of Sports Engineering at Sheffield Hallam University and was the Founding Director of the Advanced Wellbeing Research Centre there. Since the 2012 London Olympics, Steve has also been working to improve the health and wellbeing of all of us. As Chair of the Parkrun Research Board he’s heavily involved in this international phenomenon in which thousands of people have sprinted, jogged and stumbled around a 5-kilometre course on Saturday mornings, which he’s shown really does encourage people to be generally more active. Jim al-Khalili talks to Steve Haake about how he got from a physics degree to being one of the leading sports engineers in the world, and how we can all improve our health by moving more.
