Exercise has been touted to build bone mass, but exactly how it actually accomplishes this is a matter of debate. Now, researchers show that an exercise-induced hormone activates cells that are critical for bone remodeling in mice.
A study appearing in the journal Cell on December 13, 2018, identifies a receptor for irisin, an exercise hormone, and shows that irisin impacts sclerostin in mice, a major cellular regulator of bone structure in humans. The work may inform future treatments for osteoporosis, which causes more than 8.9 million fractures worldwide annually.
“These results are potential game changers in the fields of metabolism, muscle-bone biology, and exercise,” says co-author Bruce Spiegelman, a cancer biologist at Boston’s Dana-Farber Cancer Institute. “We show that irisin works directly on osteocytes, the most abundant cell type in bone.”
The article states, “Irisin, secreted by skeletal muscle in response to endurance exercise in mice and humans, has been linked to bone strengthening, calorie burning, and improved cognition. But its very existence was once controversial, and the mechanism underlying its effect on bone proved elusive.”
I concur with Dr. Spiegelman. As the founder of Fitness for Health, a therapeutic, exercise facility working with children through senior citizens in the Washington, DC, area, I have seen firsthand the power of weight-bearing exercise to improve bone and joint health in the middle age population and the importance of fitness for seniors. In fact, we are proud to have created a bone and joint health program for men and women as they age.
Fitness for Health provides a revolutionary, 12-week Bone and Joint Health Program for adults and seniors that capitalizes on weight-bearing, fitness activities. This groundbreaking program helps to improve posture and increase bone density, strength and balance while counteracting the effects of osteoporosis, osteopenia and aging.
The Bone and Joint Health Program elicits results faster and more effectively than traditional exercise (fitness for seniors) or pharmaceuticals through two state-of-the-art fitness technologies:
- bioDensity™ – Weight-bearing exercises are the key to stimulating bone growth, and the greater the weight applied, the better the results. The osteogenic loading that patients receive is multiples of bodyweight, and beyond what is typically seen in exercise. Research has shown, bone density gains that averaged 7% in the hip and 7.7% in the spine over one year using bioDensity (Jaquish, 2013). These results are multiples of what the current interventions can do for bone density.
- Power Plate™ – Power Plate is a whole body vibration platform that allows for reflexive engagement of the neuromuscular system at rapid and repeatable oscillation. This intervention has been clinically shown to increase balance and stability in both healthy and aging-frail populations.
Research has shown the bioDensity system alone has significantly increased bone mass density, stability and functional movement with multiple ages, health conditions and for both genders.
