Weight-bearing exercises promote bone formation in men
Osteoporosis affects more than 200 million people worldwide and is a serious public health concern, according to research. Now, newly published work is the first in men to show that long-term, weight-bearing exercises decrease sclerostin, a protein made in the bone, and increase IGF-1, a hormone associated with bone growth. These changes promote bone formation, increasing bone density. Ref. Source 3o.
Mechanism that underlies age-associated bone loss. A major health problem in older people is age-associated osteoporosis -- the thinning of bone and the loss of bone density that increases the risk of fractures. Researchers have now detailed an underlying mechanism leading to that osteoporosis. When this mechanism malfunctions, progenitor cells stop creating bone-producing cells, and instead create fat cells. Knowledge of this mechanism can provide targets in the search for novel bone-loss.
