1 | 23 Synthesis longitudinal panel data of NELLS to measure the number of sports practised by respondents, their frequency of sport participation and the setting in which they practised sport at two points in time with a four-year gap. The number of sports was measured as the sum of all the sports a respondent participated in, ranging for 0 to a maximum of 10 sports. To measure sport frequency, I first scored every sport by recoding the frequency categories “not at all” as 0, “less than once a month” as 0.5, “1 to 3 times per month” as 2, and “4 times or more per month” as 4 for every sport. Then I constructed a scale, from 0 to 40, adding the scores for all 10 sports. Sport setting is measured based on the setting in which respondents usually practised the sport they participated in most often. It consists of de following categories: (0) club setting, (1) commercial or alternative setting, (2) informal group setting, (3) individual setting, and (4) not practising sport at all. In the fifth chapter, I focus on the considerations, choices and changes that people make regarding their sport participation during the transition to adulthood, particularly when confronted with major life events and associated changes in resources. I turn to lived experiences based on a narrative approach, providing people’s insiders’ perspectives on their sport participation and how and why this was affected by major life events. This illuminates the underlying mechanisms via which major life events affect sport participation during the transition to adulthood, and in what way they do so, revealing differences and changes in people’s resources, their willingness to participate in sport, and ways found to do so.
