Background: The lack of a consistent national regulation regarding gym facilities, combined with the growth and transformation of the world of fitness, has led to an uncontrolled situation, where, especially in metropolitan areas, low cost gyms are continuously popping up, often not respecting the structural and hygienic requirements.
Aim of the study: Objective of this study is to evaluate the results of a monitoring programme about the gym environment, to highlight the main critical issues.
Methods: In 2018 a randomized sample of 90 gyms was inspected in Milan, using a checklist with three sections of inquiry and the resulting data were analysed through a series of multivariate regression models.
Results: As per the various aspects analysed, many outcomes with low scores concerned franchised gyms, which have shown to be unsatisfactory in many respects; in addition, the lack of L. pneumophila risk containment procedures has been observed in the facilities without a swimming pool, compared to those with it.
Conclusions: The study results offer a clear picture of the gym environment, identifying many inadequacies for different hygienic and safety aspects; therefore, it has been possible to understand which issues need particular attention in order normalize the situation, which should be checked by future investigative steps.
