Exercise fights obesity by turning stem cells into bone
Workouts can keep obesity at bay by turning influential stem cells into bone, not fat, boosting our capacity to make blood and improving overall health.
The body`s mesenchymal stem cells or MSCs are most likely to become fat or bone, depending on which path they follow. MSCs can also turn into a variety of cell types.
Using treadmill-conditioned mice, a team led by kinesiologist Gianni Parise at the McMaster University has shown that aerobic exercise triggers those cells to become bone more often than fat.
The exercising mice ran less than an hour, thrice a week, enough time to have a significant impact on their blood production, the Journal of the Federation of American Societies for Experimental Biology reports associate professor Parise as saying.
In sedentary mice, the same stem cells were more likely to become fat, impairing blood production in the marrow cavities of bones, according to a McMaster`s statement.
