[Stereotypes of ageing and sporting activity in the over-50s].

Stereotypes of ageing affect activity in older adults. However, no representative studies on the impact of "images of ageing" on sporting activity existed until now. In a telephone survey, 2002 over-50s were asked about sporting activity and their opinions about ageing. A factor analysis of the queried attitudes disclosed five dimensions of ageing stereotypes. A subsequent cluster analysis identified three categories of attitudes towards ageing: "fit and performance-hungry", "conventional", and "easy-going and committed". Physical activity was described as the key criterion for a healthy old age in all clusters. Analysis also revealed a significant correlation between cluster affiliation and amount of sporting activity. The percentage of non-exercisers is lowest in Cluster 1, the "fit and performance-hungry" category (29.4%), and highest in Cluster 3, the "worryfree committed" (51.6%). Sports for health and trendy sports are the sports of choice, while conventional sports attract little interest.
