The relationship between physical activity, meaning in life, and subjective vitality in community-dwelling older adults.

The present study examined the potential contribution of meaning in life to the relationship between physical activity and subjective vitality in older adults. Two-hundred and fifty community-dwelling elders completed the instruments assessing physical activity, meaning in life, and subjective vitality. Results from structural equation modeling indicated that physical activity was positively associated with both meaning in life and subjective vitality. Further, the relationship between physical activity and vitality was partially mediated by meaning in life. Although previous studies have consistently found a positive impact of physical activity on vitality, the current study suggested that it is more productive to focus not only on physical activity, but also on meaning in life, in order to vitalize elders. Further, a focus on meaning in life can be a productive way to continue to vitalize older adults who are unable to engage in regular physical activity.
