The relationship between serious leisure and recreation specialization in sportspeople with and without physical disabilities.

Sportspeople with and without physical disabilities in the Basque Country (Spain) (n = 370) completed a questionnaire assessing the component dimensions of two constructs, “serious leisure” and “recreation specialization”. The Serious Leisure Inventory and Measure (SLIM) and the Recreation Specialization Index (RSI) were used in the analysis. Results showed an association between these concepts in competitive sports in both samples. However, the magnitudes of association between the total of both concepts were higher in the group with physical disabilities. Regarding perceptions about their sports practice, the group without physical disabilities showed higher levels of specialization but there were no substantial differences between their levels of serious leisure participation. In conclusion, seriousness and specialization were found to be key issues for sportspeople's practice of leisure, regardless of their physical conditioneng© 2021 Published by Elsevier LtdSerious leisureRecreation specializationSLIMRSISports practicejournal article2025-04-30
