Even a Little Exercise Strengthens Bones

Heavy workouts and long hours spent at the gym aren’t the only way to benefit from exercise. New research has found even minor physical activity can offer major health benefits by strengthening bones in premenopausal women prone to osteoporosis.
The small study, published in the Endocrine Society's Journal of Clinical Endocrinology and Metabolism, found physical activity is very effective in reducing sclerostin – a known inhibitor of bone formation – and can have a very positive effect on bone formation.
"Physical activity is good for bone health,” said lead researcher Mohammed-Salleh M. Ardawi, an osteoporosis specialist at King Abdulaziz University in Saudi Arabia. "We also found physical activity training that enhances mechanical loading in combination with anabolic therapeutic agents will have added positive effect on bone health, particularly bone formation."

For the study, researchers tracked 58 women during an eight-week course of physical activity training and compared them with 62 others who engaged in little exercise. All women were medically examined and measurements were taken for bone mineral density, sclerostin and other bone-related factors.
The results showed women who had more than two hours of physical activity per week had significantly lower levels of sclerostin and higher levels of a substance called “IGF-1” that promotes bone formation than those who had less than two hours of physical activity per week.
"Physical activity training is conceptually simple, inexpensive, and can serve practical purposes including reducing the risk of low bone mass, osteoporosis, and consequently fractures," said Ardawi. "Our study found that even minor changes in physical activity were associated with clear effects on serum levels of sclerostin, IGF-1 and bone turnover markers."
