ABSTRACT

Research question

Can evidence of trickle-down-effects be observed among youth living in the hometowns of Canadian athletes that competed and/or won medals at the London 2012 Olympic Games?

Research methods

Leisure-time physical activity (LTPA) rates of male and female youth were extracted from the Canadian Community Health Survey (n > 1,000,000) for 110 health regions during the pre-Olympic (2009/2010), Olympic (2011/2012), and post-Olympic (2013/2014) year periods. The health regions were treated as panel units and, beyond Canadian athletes and medallists, the panel data analysis incorporated population size and previous Olympic hosting as control variables in the model.

Results and findings

The panel analysis revealed that the number of Canadian athletes representing youths’ hometowns at the London 2012 Olympic Games was negatively associated with LTPA rates when considering the full sample of youth, and male youth in particular. Interestingly however, winning medals (of any colour) was positively associated with hometown LTPA rates among the full sample of youth and male youth. Hometown population size was negatively associated with LTPA rates for the full sample of youth and female youth specifically. Winning a gold medal and hosting previous Olympic/Paralympic Games were not significantly associated with hometown LTPA rates when considering the full sample of youth or male and female youth separately.

Implications

Our study demonstrates a need for researchers and sport managers to consider the spatial reach and scope of trickle-down-effects beyond that which can occur within a host nation. These effects have the potential to be a global phenomenon.

超越主办国：对参加 2012 年伦敦奥运会的加拿大运动员“家乡”的涓滴效应进行调查

摘要

研究问题

在 2012 年伦敦奥运会上参加比赛和/或赢得奖牌的加拿大运动员家乡的年轻人中是否可以观察到涓滴效应的证据？

研究方法

男性和女性青少年的休闲时间体力活动 (LTPA) 率是从 奥运会前 (2009/2010)、奥运会 (2011/2012) 和奥运会期间 (2011/2012) 期间对 110 个卫生区域的加拿大社区健康调查 ( n > 1,000,000) 中提取的。奥运会后（2013/2014）年份。健康区域被视为面板单位，除了加拿大运动员和奖牌获得者之外，面板数据分析还纳入了人口规模和之前的奥运会主办情况作为模型中的控制变量。

结果和发现

小组分析显示，考虑到青少年的完整样本，特别是男性青少年，代表青少年家乡参加 2012 年伦敦奥运会的加拿大运动员人数与 LTPA 率呈负相关。然而有趣的是，在青年和男性青年的完整样本中，赢得奖牌（任何颜色）与家乡 LTPA 率呈正相关。对于青年和女性青年的完整样本而言，家乡人口规模与 LTPA 率呈负相关。当单独考虑青少年或男性和女性青少年的完整样本时，赢得金牌和举办以前的奥运会/残奥会与家乡的 LTPA 率没有显着相关。

影响

我们的研究表明，研究人员和体育管理者需要考虑滴流效应的空间影响和范围，超出东道国境内可能发生的范围。这些影响有可能成为一种全球现象。
