The concept of subjective vitality refers to the state of feeling alive and alert; to have energy available to oneself. The aim of the present study was to translate and analyze the psychometric properties of the Portuguese version of the Subjective Vitality Scale in a sample of 935 exercisers, both men (344) and women (591). The results of the confirmatory factor analysis confirmed the good adjustment of the original factorial model (S-B χ² = 34.93; p = .000; χ²/gl = 3.88; NNFI = .961; CFI = .970; RMSEA = .074 con 90% CI =.049-.101). Also, concurrent validity was obtained through the application of the Portuguese versions of the Rosenberg Self-Esteem Scale and Satisfaction with Life Scale. In the same way, reliability of the scale throughout the analysis of internal and temporary consistency was also demonstrated. The present findings support the use of the Portuguese version of the Subjective Vitality Scale to assess vitality among Portuguese exercisers.
