Previous issue date: 2008-03-11 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The study of the motivation to practice physical activities is relevant once through this it is possible to develop intervention strategies for sedentary population. In this way, the present dissertation aimed to adapt and validate for the Brazilian context the Motives for Physical Activity Measure Revised (MPAM-R). It was investigated yet the relation of some socio-demographic variables (age, gender, Body Mass Index - BMI, types of physical activity; way to practice and time of practice) and the participants means in the motives studied. The physical activity (PA) is defined as any bodily movement produced by skeletal muscles resulting in energy expenditure above the basal level. However, in the present study it was considered motivation for two types of PA: the physical exercises and sports. The Self-Determination Theory (SDT) underlay this research, once it has been used in the sportive context, beyond the facto of it was used as theoretical base to the development of MPAM-R. To attain the proposed goals, it was accomplished translations to Portuguese of the original English scale. Next, was carried out the semantic analysis and the judge analysis. For the empirical analysis of items, participated 309 practitioner of PA, classified in physical exercises practitioners and sports practitioners, with ages between 16 and 74 years, distributed equally by sex. They answered the final version in Portuguese of the MPAM-R and socio-demographic questions. The data was collected in Natal/RN, where the researcher approached people in some places where the PA is practiced,
following she communicated that their involvement will be spontaneous and their responses will be confidential. The obtained results pointed the confirmation of the existence of five factors in the final version of the instrument, that was composed by 26 items that presented the following
statistics indexes: x? (289) = 757.75, p < 0.000, x?/DF = 2.62, with GFI of 0.83, AGFI of 0.80 and RMSEA of 0.07. The reliability (Cronbach Alpha) of the complete instrument was 0.90, and the indexes of each factor were considered satisfactory too: Enjoyment (α = 0.88), Health (α = 0.84), Appearance (α = 0.79), Competence (α = 0.85) and Social (α = 0.75). It was observed that, in general, the main motive presented by the participants to practice PA was Health. It was verified yet, that women and aged had a higher mean in the Health factor; among the exercise practitioners was found a higher mean in the Appearance factor; and a higher mean in the Social factor was found among those that practice PA with accompaniment. It was concluded that the MPAM-R presented satisfactory psychometric parameters, became it useful in futures researches. Moreover, proposed the accomplishment of new studies that considered others variables to the intent of the better understanding of motivation to practice physical activity / O estudo da motiva??o para a pr?tica de atividades f?sicas ? relevante no sentido de viabilizar poss?veis estrat?gias de interven??o junto ? popula??o sedent?ria. Desta forma, a
presente disserta??o objetiva adaptar e validar para o contexto brasileiro a Escala de Motiva??o ? Pr?tica de Atividades F?sicas (Motives for Physical Activity Measure Revise MPAM-R). Buscase ainda verificar a m?dia dos participantes nos motivos estudados em decorr?ncia de algumas vari?veis s?cio-demogr?ficas: idade, g?nero, IMC (?ndice de Massa Corporal), tipo de atividade f?sica; forma de praticar e o tempo de pr?tica. A atividade f?sica (AF) ? definida como todo movimento corporal produzido pela musculatura esquel?tica, que resulte em um gasto energ?tico maior do que os n?veis de repouso. Entretanto, no presente estudo considera-se a motiva??o para dois tipos de AF: os exerc?cios f?sicos e os esportes. Toma-se por base a Teoria da Auto- Determina??o (TAD) que tem sido utilizada no contexto esportivo e serviu de fundamenta??o te?rica ao desenvolvimento da MPAM-R. Para atingir os objetivos propostos, foram realizadas tradu??es da escala original em ingl?s para o portugu?s. Em seguida, realizou-se a an?lise
sem?ntica e a an?lise dos ju?zes. Para a realiza??o da an?lise emp?rica dos itens, contou-se com a colabora??o de 309 praticantes de AF, classificadas em exerc?cios f?sicos e esportes, com idades entre 16 e 74 anos (M = 35 anos; DP = 14,11), distribu?dos eq?itativamente quanto ao sexo. Estes
responderam a vers?o final em portugu?s da MPAM-R e quest?es s?cio-demogr?ficas. Os dados foram coletados na cidade do Natal/RN, abordando as pessoas em locais onde se pratica AF e assegurando-lhes o car?ter volunt?rio e confidencial de suas respostas. Os resultados obtidos
indicaram que foi confirmada a exist?ncia de cinco fatores no instrumento final, que ficou formado por 26 itens apresentando os seguintes ?ndices estat?sticos: x? (289) = 757,75, p < 0,000, x?/gl = 2,62; GFI = 0,83, AGFI = 0,80 e RMSEA = 0,07. A escala total apresentou consist?ncia interna (Alfa de Cronbach) de 0,90, sendo os ?ndices espec?ficos de cada fator tamb?m considerados satisfat?rios: Divers?o (α = 0,88), Sa?de (α = 0,84), Apar?ncia (α = 0,79), Compet?ncia (α = 0,85) e Social (α = 0,75). Observou-se que, no geral, os participantes deste estudo praticam AF mais por quest?es de Sa?de. Verificando-se uma maior m?dia no fator Sa?de para mulheres e idosos; maior m?dia no fator Apar?ncia para os praticantes de exerc?cios e, finalmente, maior m?dia no fator Social entre aqueles que praticam AF acompanhados. Concluise que a MPAM-R apresenta par?metros psicom?tricos satisfat?rios, podendo ser utilizada em pesquisas futuras. Ademais, sugere-se a realiza??o de novos estudos que considerem outras vari?veis em busca de melhor compreender a motiva??o para a pr?tica de AF
