One hour a week of exercise prevents disability: study

The finding is one-third less than the amount of exercise currently recommended, which should help patients who report time as a barrier, researchers say

Just under one hour of moderate to vigorous exercise each week is all that is needed to help patients with hip, knee and ankle joint symptoms remain disability-free, according to a US study.

While most health agencies recommend 150 minutes of moderate-intensity exercise per week to prevent disability, the Northwestern University-led researchers have found just 56 minutes is the threshold for preventing mobility disability (gait speed less than 1m/second) over four years.
