Just one hour a week of brisk walking may prevent disability in older adults with arthritis pain, or aching or stiffness in the knee, hip, ankle or foot, a new study suggests.
The findings suggested that an hour of weekly moderate-to-vigorous physical activity allowed older adults to maintain their ability to perform daily tasks like getting dressed or cross a street before a traffic light walk signal changed.
"This is less than 10 minutes a day for people to maintain their independence. It's very doable," said lead author Dorothy Dunlop, Professor at the Northwestern University Feinberg School of Medicine in the US.
"This minimum threshold may motivate inactive older adults to begin their path toward a physically active lifestyle with the wide range of health benefits promoted by physical activity," Dunlop added.
For the study, published in the American Journal of Preventive Medicine, the researchers analyzed four years of data from more than 1,500 adults.
