For women to decrease mortality risk: lift weights like your life depends on it

A study followed 750 women aged 50-94 years for a decade.  Researchers wanted to see the effect of changes in bone mineral density (BMD) and appendicular lean mass (ALM) on mortality. The study found that deaths increased as BMD and ALM diminished irrespective of age.

A quote from the study, Musculoskeletal decline and mortality: prospective data from the Geelong Osteoporosis Study:

“Poor musculoskeletal health increased the risk for mortality independent of age. This appears to be driven mainly by a decline in bone mass. Low lean mass independently exacerbated mortality risk, and this appeared to operate through poor health exposures.”

From this study, Musculoskeletal decline and mortality: prospective data from the Geelong Osteoporosis Study, the conclusion:

“Poor musculoskeletal health increased the risk for mortality independent of age. This appears to be driven mainly by a decline in bone mass. Low lean mass independently exacerbated mortality risk, and this appeared to operate through poor health exposures.”

The takeaway: Stay as strong as you can as long as you can.

Got Sarcopenia? If you are over forty you have it

The term sarcopenia has not been in common usage for very long (see graph), but the condition has been around forever.  Sarcopenia is the loss of muscle tissue that occurs as a natural part of the aging process. According to this article, Why You're Aging Ungracefully, there are two things we can do to help maintain our muscle as we age - lift weights and eat high-quality protein.

A quote from the article:

Sarcopenia begins naturally in the 4th and 5th decades of life, making your 40s and 50s an ideal time to increase dietary protein and weight training, but even those in their 60s and beyond can benefit."

Another quote:

"The stronger you are, the more muscle you have, the less likely you are to become sick or die."
