Governments allocate resources to Sports Federations in pursuit of competitive outcomes that depend on a combination of uncertain factors. This study applies the Färe-Primont index (FPI) for the first time in the field of sport to estimate productivity and efficiency and analyse the results of Spanish Sports Federations’ participation in the last four editions of the Olympic Games (2008–2021). It also seeks to identify the existence of behavioural patterns in Spanish Sports Federations that make the best use of the available resources. The results of the study suggest that the structure of funding sources, the size of the governing bodies and the length of time that the SSFs compete for (age) are factors that influence their efficiency and productivity.2026http://zaguan.unizar.es/record/16994510.1177/21582440251411375http://zaguan.unizar.es/record/169945oai:zaguan.unizar.es:169945info:eu-repo/grantAgreement/ES/AEI/PID2024-159374NB-I00SAGE Open 16, 1 (2026), [20 pp.]by-nchttps://creativecommons.org/licenses/by-nc/4.0/deed.esinfo:eu-repo/semantics/openAccess
