Physical Activity in Older Persons.

: Physical activity in older adults has been shown to improve physical, cognitive and functional status and to reduce risk of frailty. Guidelines recommend at least 150 minutes of moderate-intensity aerobic physical activity each week as well as strength activities. There is little evidence of adverse events or harm with regular physical activity in older adults. Group-based and center-based models may help maximize short-term benefits, but creating home-based activities can improve the long-term compliance of a physical activity program.
