Q: What happens to the muscle fiber content during aging?
Answer:
as you age, the number of fibers in each muscle will decline
Q: During aging, does muscle mass or strength decline more rapidly?
Answer:
strength decreases more rapidly
Q: Why is strength decreased in aging?
Answer:
there are decreased cross bridge kinetics, which slows contractile velocity and
decreases the amount of force produced

Answer:
there is initially a rapid increase in the rate of bone loss, but it eventually equalizes to
what is normal for age
Q: What happens to the bone density of men as they age?
Answer:
they los bone density
Q: How can you identify age related decreases in bone density on imaging?
Answer:
when there are less dark spots on the film, which means that there is less
mineralization
