Quick Answers...
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.
