O objetivo deste estudo foi analisar a associação entre a motivação e vários aspectos da prática de exercício físico (EF) em indivíduos que mantiveram a perda de massa corporal, e explorar o papel do gênero. A amostra foi constituída por 253 participantes, foram avaliadas as suas características sociodemográficas, a composição corporal, o EF, a motivação geral e específica para o exercício, com instrumentos validados. Utilizou-se o teste t-de student para comparar as diversas variáveis entre os participantes. Para analisar a associação entre as variáveis motivacionais e os diferentes aspectos do EF, utilizou-se o coeficiente de correlação de Pearson. Foram ainda criados tercis para as variáveis motivacionais e posteriormente comparadas as médias dos vários aspectos do EF, através do teste da ANOVA one-way. Observaram-se diferenças entre gêneros no que respeita à intensidade, duração e dispêndio energético e na maioria das variáveis motivacionais, favorecendo o gênero masculino. Identificaram-se associações positivas entre as variáveis motivacionais relacionadas com o EF, nomeadamente a motivação intrínseca e as regulações de ordem mais autônoma, e os diferentes aspectos do EF, na amostra total e no gênero feminino (p < 0,05). Em indivíduos com sucesso na manutenção da perda de massa corporal, particularmente nas mulheres, motivações mais autônomas para o EF associaram-se a maior prática de EF. Essas conclusões são significativas para programas de perda de massa corporal e promoção de saúde, indicando que a motivação autônoma pode ser um fator de sucesso na manutenção da massa corporal.
