Bone Density: High Impact

But it also might be good for the health of your bones. We’re not saying you have to hit 332 jumps per minute, but even at a leisurely pace, a little jumping can be good for your bones.

 

As it turns out, when bones receive a moderate impact (we’re talking a moderate impact from movement like running or jumping) bones make themselves stronger.

 

In a recent study (playfully titled Physical activity and bone: may the force be with you) it was discovered that young persons, whose bones are still developing, can increase bone density with physical exercise which included moderate impact activities. The hope is that building bone density in young people will help provide protection from future bone loss issues such as osteoporosis, although further research into long-term effects is needed. And these clever scientists weren’t the only ones to find such promising results from moderate impact exercise. In another study of premenopausal women, when bones were subjected to a moderate force from jumping, hip bone density increased.

 

As we age, the risk of bone loss and all its negative side effects increases. One of the best preventives for future problems with osteoporosis is to start with strong bones. These studies show we can improve bone strength over a relatively short period of time with purposeful, moderate impact activity.

Task Force Guidelines on Aorta Screening in Smokers

This is a call to older male smokers. As a smoker you are at risk for many health issues. While heart and lung conditions are the more commonly known diseases for smokers, vascular diseases are another. Abdominal aortic aneurysm, or “AAA,” is yet another significant health issue that may be seen with higher frequency in smokers. An aneurysm is an abnormal ballooning or dilatation of a blood vessel. In this case, the aneurysm involves the aorta – the main artery carrying blood to the abdomen and lower body. As the aneurysm gets bigger, there is a risk of sudden death from rupture.

Recently the USPSTF, a task force that reviews guidelines and screening studies, came forward with a recommendation with the intention of saving lives. The Task Force has issued a recommendation for ultrasound screening of male smokers over the age of 65 for the presence of an abdominal aortic aneurysm. Further research is needed to determine the usefulness of the screening test both in women who smoke and in older male non-smokers.

Making use of the simple non-invasive technology of ultrasound, one-time screenings for men in the high risk category will help improve survival from complications of abdominal aortic aneurysm. For more on the recommendation, we recommend this resource.
