Physical fitness is a key parameter to determine the health status of the elderly. However, the factors that define health-related fitness are poorly characterized, resulting in a wide variety of tools (test batteries). These batteries, which are used internationally, have not been validated to the Spanish language and their usage in Spanish-speaking countries could present a methodological problem as far as their scientific application is concerned. The purpose of this article was to analyze and compare the test batteries developed for the elderly and which have been written in Spanish.
