In our 2012 article on the ‘Sport participation legacy of the Sydney 2000 Olympic Games and other international sporting events hosted in Australia’ (Veal, Toohey, & Frawley, 2012), we summarised the long history of claims, by governments and sports organisations, that hosting international sports events provides a range of sport-related and other benefits to the host community. In particular we focussed on claims made in relation to grassroots sport participation, sometimes referred to as recreational sport, mass sport or sport for all. Our research raised doubts about such claims in the case of Australia. Since that time, systematic reviews of the research literature, notably by Weed et al. (2015), have indicated a consensus among researchers that there is no evidence to support the ‘trickledown effect’ in sport.
