Resumo

Background: Identifying the motives why people exercise is interesting for the planning of effective health promoting strategies. Objectives: To estimate the psychometric properties of the exercise motivations inventory (EMI-2) in Brazilian and Portuguese university students, and to compare motive-related factors for exercise among students. Methods: One thousand Brazilian (randomly splitted into "Test sample" [n=498] and "Validation sample" [n=502]) and 319 Portuguese students participated in this cross-sectional study. Motives for exercise were evaluated using EMI-2. Exploratory factor analysis was performed in the test sample. Then, confirmatory factor analysis was performed in the validation and Portuguese samples. The EMI-2 scores were compared according to sex, exercise, and weight status (ANOVA, alpha=5%). Results: EMI-2 factor model was explained by 5 factors and presented adequate fit (chi(2)/df <= 3.2; CFI >= 0.9; TLI >= 0.9; RMSEA <= 0.07; and alpha >= 0.83). The motives for exercising were mainly related to psychological and interpersonal factors for men, health-related factors for women, and body-related factors for overweight and obese individuals. People who practice exercise had higher EMI-2 scores. Conclusion: The 5-factor model is suggested for a comprehensive assessment of motives for exercise. Individual characteristics should be considered for development of tailored protocols. (AU)
