Bones Benefit from High G-Force Exercise

As people age, bones are known to deteriorate and lose mass. A study at the University of Bristol shows that high impact activities can stop bone mass reduction. Results have also shown that bones can build additional mass through these intense exercises. Individuals in their adolescent years were monitored to support this theory. Interesting findings on women over 60 years of age also provided more scientific information.

Scientists analyzed female and male teenagers. The adolescent years are a prime time where individuals develop bone mass. Scientists took measurements of their hips and set them up with monitors able to measure G-forces. Participants went through their typical day and upon analysis, findings showed that certain activities can result in more benefits for the bones. Movement that involves jumping at least 15 inches high or running a mile in ten minutes provided the highest G-force of 4.2 or higher, the amount determined to build bone.

Older women, above the age of 60, were also monitored as they were put through an aerobics course. Unfortunately, none reached the 4G marker. However, the finding revealed more information. In looking to only maintain bone mass, physical activity is beneficial, but scientists have yet to determine how much G force under that threshold would provide the same results. An unfortunate reality is that the type of exercise that is most beneficial for older adults may be too strenuous. Seniors and those who have not been consistently active will especially need to consult a physician regarding the status of their bones. Studies will continue regarding what levels of low impact activity will still prove beneficial.

Dr. Tobias, a professor from the university who led these experiments intends to continually incorporate running into his lifetime routine. He agrees that it is unfortunate that the people who can most benefit from high impact movement may not be able to withstand it. To find more solutions, he is confident about his upcoming research and the findings of his colleagues. In the meantime, he strongly encourages young adults to regularly sprint or jump to support their bone health.
