Research indicates that while nurses are aware of the benefits of physical activity (PA), their adherence to PA is low. The results of workplace interventions that increase PA are inconsistent. The study aim was identification the sociodemographic, professional, and incentive factors influencing nurses' PA and investigation its relationship with the level of PA that they report. This study was based on observational cross-sectional research conducted among professionally active nurses working in a clinical setting (n = 350). The self-reported questionnaire was used to collect sociodemographic and employment data and motivators and barriers of participating in PA. The level of PA was assessed using International Physical Activity Questionnaire. The analysis revealed significant differences in the Total Physical Activity Score (TPAS) depending on the variables related to professional activity (working in a management position: p = 0.015; workplace: p = 0.01; shift type: p ≤ 0.002). Cluster analysis revealed that the most important statement in the group division about motivation was fear of the pain occurring after exercise. Nurses who were more motivated to be active showed a higher level of leisure-time PA than less motivated nurses. The recommendation of PA in the nursing population should be focused on increasing the leisure time PA, ensuring the appropriate time to recovery, and compliance with the principles of work ergonomics to prevent musculoskeletal disorders.
