Daily Physical Activity: Relation to Everyday Memory in Adulthood.

Area of Science:

• Cognitive psychology
• Gerontology
• Behavioral neuroscience

Background:

• Everyday memory failures are common across adulthood.
• The relationship between physical activity and memory is well-established, but daily fluctuations are less understood.

Purpose of the Study:

• To investigate the daily association between physical activity and memory failures in young, middle-aged, and older adults.
• To determine if age moderates the short-term effects of physical activity on memory.

Main Methods:

• An eight-day diary study design was employed.
• Participants (young, middle-aged, older adults) recorded daily physical activity and memory failures.
• Multilevel modeling and lagged analyses were used to examine within-person relationships.

Main Results:

• No significant age differences were found in overall daily physical activity or memory failure frequency.
• On days with leisure exercise, participants reported fewer memory failures.
• This effect was more pronounced in older adults, with leisure activity on one day predicting fewer memory failures the next.

Conclusions:

• Daily leisure exercise is associated with reduced memory failures, especially in older adults.
• Physical activity provides short-term, observable benefits for memory in later life.
• Interventions promoting daily physical activity may enhance everyday memory functioning in older populations.
