Only 1 hour a week of brisk walking staves off disability.
People with osteoarthritis who walk briskly as little as 1 hour per week can significantly increase their odds of remaining functionally independent. Northwestern University researchers in Chicago examined more than 4 years of data from more than 1,500 adults—age 49 or older—who had arthritis but no disability. Their activity levels varied. Activity data analysis showed that people who did 1 hour of moderate-to-vigorous activity per week had a higher probability of remaining free from disability than those who exercised less.
