One of the key questions about the London 2012 Olympics and Paralympics is about a physical activity ‘legacy’. Will the biggest sporting spectacle on earth ‘inspire a generation’ to become physically active and to participate in sport? Only last week the Prime Minister, David Cameron, appeared confident that there would be such a legacy when he claimed that sport in schools in the UK is likely to be influenced positively by the Olympic spirit. Yet, the evidence from previous Olympics tells a different story. No Olympic Games has ever led to a sustained participatory legacy although, to be fair, London is the first to set out explicitly to provide one. So, as the Olympics approach and the torch relay winds its way around the country, concerns about delivering an Olympic legacy are becoming more pronounced. The reason for this concern is simple: a ‘legacy’ (or ‘legacies’) is what we hope to get in return for all our financial investment. As sports mega-events become ever more bombastic, expectations for a ‘legacy’ rise accordingly. This means that while British viewers will be interested in Team GB‘s position on the all-important medal table, the Coalition government will be hoping, inter alia, for an increase in participation in grass roots sports, sports competitions and physical activity.
