Just how useful is walking, as a low-impact exercise? Does the ten thousand steps per day rule need revision?
Perhaps. A new study has found that women who walk in excess of ten thousand steps per day do not have better muscle strength than those who walk less than seven thousand.
No Muscle Difference
Women aged between fifty and seventy years were split into three groups: low activity (fewer than 7500 steps walked per day); medium activity (7500-10000); and high activity (10000+).
Despite the significant variance in level of walking activity, Muscle strength, and body muscle mass percentage, was found to be the same across the three groups.
“None of us think that if you walk a huge amount that you’re going to have huge muscles,” says Catrine Tudor-Locke, a professor at Pennington Biomedical Research Centre.
There were some advantages gained from walking more, however. Those who walked more did tend to weigh less, and have lower percentages of body fat.
What do you think? Worth the effort, or over-rated?
