Fitness Sports: Motives, Dropout & Evaluation of FacilitiesSocial change and increasing leisure time have led to a new understanding of sport. Sport is no longer just high-performance sport, but also sport for better health and an occupation in leisure time. The change in demand for more sports, and above all for a different way of experiencing sports, has led to a change in the supply structure. The market is no longer dominated by traditional oriented sports, but by a non-negligible number of companies offering physical activity activities that try to meet the diverse needs and desires of people. All value-added processes of companies must be completely focused on meeting customer expectations. Findings from studies on motives, dropouts and evaluation in fitness sports can help, on the one hand, to take into account the specific wishes of athletes when designing offers and, on the other hand, to implement their marketing more effectively through more specific target group orientation.
