Muscle Fibrosis and Aging: Why Strength Fades and What Can Be Done
As we age, many people assume that weakness and muscle loss are inevitable. While some decline in strength is expected, much of what we attribute to “aging” is actually due to specific biological processes, particularly muscle fibrosis. Unlike muscle atrophy alone, fibrosis involves a shift in tissue architecture, replacing healthy muscle fibers with stiff, disorganized collagen. This change reduces mobility, strength, and responsiveness to exercise.
