Affective response to daily physical activity in younger and older adults.

Many older adults do not meet the physical activity recommendations of the American Heart Association; hence, it is important to understand the factors that can facilitate regular physical activity in older adults. Notably, the role of affective response has been understudied. Mixed findings have been reported in terms of age effects in affective response to daily physical activity. This study aimed to determine age differences in affective response to daily physical activity and whether these differences are associated with overall physical activity levels. Further, the role of contextual factors in age differences in affective response following daily physical activity was examined. Younger (n = 59) and older adults (n = 60) completed 1 week of experience sampling during which they responded to daily prompts about their affect and physical activity. Overall physical activity levels were estimated via actigraphy. In both age groups, daily physical activity was similarly associated with greater high-arousal positive (HAP) affect relative to other activities. Across age groups, participants reported more HAP affect when engaging in daily physical activity in a group compared to alone. Greater duration and enjoyment of daily physical activity were more strongly associated with greater HAP affect in younger adults relative to older adults. Affective responses following bouts of daily physical activity did not predict overall physical activity levels for either age group. Overall, older adults may experience similar positive affective response to younger adults following daily physical activity relative to other activities. These affective responses may have a limited role in physical activity engagement in daily life. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
