Abstract
This research aims to verify whether physical activity influences the levels of self-esteem and depression in the elderly. The sample is constituted by 215 subjects (61 males and 154 females), practitioners and non-practitioners of physical activity, aged 60 to 100 years. The study variables were evaluated by applying two instruments, the Rosenberg Self-Esteem Scale and the Anxiety, Depression and Stress Scale (DASS-21). The results showed that elderly people who practice physical activity reveal high levels of self-esteem and lower levels of depression. It was found that self-esteem decreases with age, while depressive symptoms increase. Gender, marital status, educational level and institutionalization reached statistical significance in the self-esteem scale. Were elderly male, with partners, higher educational level and non-institutionalized who reported higher levels. We conclude that as the frequency of physical activity increases, levels of selfesteem become more accentuated, while levels of depression decrease. Regarding the relationship between self-esteem and depression, there was a negative correlate with small effect. © 2016: Servicio de Publicaciones de la Universidad de Murcia Murcia (España).
