Despite not keeping at it, men at a young age who exercise retain some of the perks to their bones into old age. Researchers compared throwing arms and non-throwing arms of professional baseball players over time.
With physical activity during youth, the bone strengthen, also increases mass and size. However, it was still uncertain whether those benefits is maintained during old age. The researchers checked about 100 pro baseball players and about 90 “regular” men. Based on their findings, about half of the bone size and 1/3 of the bone strength were retained permanently.
Thus, it is concluded that encouraging physical activity at a young age is vital for bone health focusing on developing bone strength and size rather than mass.
