Considering wider societal developments that reflect a demand for personalised services, this study aims to uncover the relationship between the perceived need for change by voluntary sports clubs (VSCs), their adoption of innovative services to promote flexibility of sports participation (also referred to as ‘light’ sports initiatives) and their organisational growth (in terms of membership evolution). Simultaneously, the impact of key organisational capacity (OC) determinants on each of the aforementioned variables is taken into account. In this study, VSCs in Flanders (Belgium) are examined utilising three (generalised) linear mixed model analyses on longitudinal panel data from 2012, 2015 and 2018. The results show a positive relationship between the need for change on the one hand and the adoption of ‘light’ sports initiatives and organisational growth on the other hand, whilst adopting ‘light’ sports initiatives as types of service innovations do not necessarily lead to organisational growth. The results of this study offer implications for the management and policy of VSCs to cater to shifting member demands. This study serves as a stepping-stone for further research to investigate other types of innovation on organisational change and growth.
