Assessing the correlates of older adults’ leisure-time physical activity (PA) is essential to effectively promote these populations’ active lifestyles. Few studies have been published about PA correlates of older adults in Poland. The aim of this study was thus to identify correlates of self-reported PA of older adults. Participants were 577 members of senior citizen clubs aged 70.72±8.04 years. Questionnaires were used to collect data of PA, psychological, perceived social and environmental variables related to PA. Results of regression analyses with four levels of PA as dependent variables and psychosocial factors as independent variables showed that all models were significant, explaining the variance from 8% (walking) to 20% (VPA). Age and accessibility of fitness facilities were significant predictors in the final regression equation used to explain all levels of PA except walking. Time spent on TV predicted walking, LPA and MPA.
