Bones and Brain

“If you exercise regularly, then it stimulates your bone to make more Osteocalcin, and that will have these beneficial effects on muscle and brain,” he says. “From epidemiological studies, we know that people who are very active tend to have less of a cognitive decline with age than sedentary people. With time, maybe people will be more aware of this connection, and think of their bone health as being just as important as other aspects of staying healthy.”

John Jacquish developed a device to help his mother's osteoporosis. It was a part of his PhD research. He went on to form a company to offer this as a service.

One of the things the research showed is you need a 4.2g force loading at a minimum to send a signal to create bone growth. Some of this research comes from studying gymnasts who get maybe 10x on their dismounts. His device was developed to apply this loading safely, especially to older women.

He also has an iOS app that will measure this during an exercise session. I have the app and you need to be able to connect your phone tightly to your body for the accelerometer to accurately measure the force. I've found that jumping rope on a thin pad on concrete barefoot will do this.

Jacquish also has a book.

An outgrowth of his research was the development of the X3 bar system. The concept is that variable resistance gives a much stronger signal for muscle growth. His system includes a ground plate, very high quality resistance bands and hand held bar and a program. The program does give an excellent workout, from my experience.

A couple of podcasts talking about the OsteoStrong as well as the X3 bar are here and here.
