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.
