The stages of change through a survey that found six stages: precontemplación, contemplation, preparation, action, maintenance and relapse. The differences between the groups identi-fied by Chi2 test. Results: 60% of respondents are in the first three stages of change and only 44%t are physically active. Students categorized in stages precontemplatión, contemplation and preparation presented lower energy expenditure (EMT); while subjects in action and maintenance stages showed greater consumption. Conclusions: There is a significant relationship between energy expenditure (METs) and the stages of change for physical activity. It is suggested that interventions to promote physical activity should consider each stage of change.
