Does physical strength decline in old age?
Yes. Muscle mass declines, cartilage erodes, membranes fibrose (harden), and fluid thickens. These contribute to stiffness, gait problems, lessened mobility and limited range of motion. From age 30 years, muscle mass declines to almost 50% in old age. Research shows that weight-bearing exercise, aerobics, and weight resistance can restore muscle strength, increase stamina, stabilize balance and minimize falls.
