This second criterion was added because the relationship between muscle cross-sectional area (i.e. size) and force production (i.e. strength) is […]
By Austin Baraki In our first article we defined sarcopenia as a loss of skeletal muscle mass and strength. We discussed how disuse, poor nutrition, neuromuscular changes, hormonal status, and chronic inflammation contribute to loss of skeletal muscle protein. In today’s article we’ll examine the other side of the equation that affect skeletal muscle protein […]
