The aim of the study was to determine the influence of leadership, engagement and perceived stress on workers in fitness centres. Conducting a quantitative, descriptive cross-sectional study. The sample consisted of 106 workers, with an average age of 35 years (35.2 ± 8.5). The instruments used were, Multifactor Leadership Questionnaire (MLQ-6S) to measure the type of leadership; the Utrecht Work Engagement Scale (UWES) to know the level of engagement and Perceibed Stress Scale (PSS) to know the perception of stress. Variables, tStudent, ANOVA and Pearson (r) linear correlation and multiple linear regression are compared and correlated. The main results highlight that the level of perceived stress is higher in permanent workers (20.97) and women (21.54). In conclusion, a higher level of engagement translates into a lower level of perceived stress.
