Promotion of physical activity has become a global priority for public health. While many people do not adhere to the recommendations, sport and exercise maintainers have found their right or fitting practice. Thus, assessing and knowing the participation motives across maintainers helps to improve our understanding of the sports and exercise practices and, thus, to recommend and to design physical activities and programmes that fit to individuals' motives. A modified version of the Bernese Motive and Goal Inventory was used in an Austria-wide cross-sectional study with 10646 sport and exercise maintainers (43% female). The study performed confirmatory factor analysis, examined measurement invariance, and compared participation motives. The results showed a good model fit and measurement invariance, indicating that the inventory can be applied independently of gender, age and years of sport/exercise experiences. Motives differed among gender, age and type of sports/exercise. Therefore, these variables should be considered in tailoring sport recommendations and interventions to promote adherence. Finally, the results are discussed by using the Self-Determination Theory indicating that sport and exercise maintainers pursue predominantly motives with intrinsic goal contents.
