abstract: OBJECTIVE
  To know the influence of the factors that determine physical exercise in adults and elderly by the analysis of the determinants categories of health-promoting behaviors in the health promotion nursing model (MPS) of Pender.

The databases consulted were PubMed-MEDLINE via RefWorks bibliography manager, CUIDEN and CUIDATGE. The search was conducted in 2010 and 2011, including publications in English and Spanish.
  
  
  RESULTS
  18 articles were reviewed to assess the influence, in adult and elderly population, of the factors: prior related behavior; personal factors; perceived benefits of action; perceived barriers to action; perceived self-efficacy; activity-related affect; interpersonal influences; situational influences; immediate competing demands and preferences; commitment to a plan of action. DEVELOPMENT AND DISCUSSION: Many studies have demonstrated the validity and predictive ability of the model studied in this article (MPS). There are complex biopsychosocial processes that motivate individuals to engage in behaviors to promote health. The MPS variables and their relationship are relevant in the decision to adopt increased physical activity behaviors.
  
  
  CONCLUSIONS
  The Health Promotion Model facilitates the evaluation of the elements that influence behavior and helps nurses to identify how willing a person to exercise, what are their difficulties and can decide what interventions are most seek to promote physical activity.
