Sarcopenia And The Media

Older individuals have the most to gain from strength training. Six weeks of dedicated strength training will normalize balance, rejuvenate posture, revive the metabolism, and eliminate long-standing pain.  I often tell physical therapy patients that strength training is the “fountain of youth”.  Unfortunately, it is difficult to convince older individuals that they need to become dedicated to a routine of consistent resistance training.  I recently got some help from Jane Brody in the New York Times, *Preventing Muscle Loss Among the Elderly.

Drs. Evans and Rosenburg are Tufts University researchers interested in the physical attributes that keep humans healthy and vigorous over an entire life span.  They have determined that the top four biomarkers are:

  1. Muscle Mass.  What percentage of your body is made of muscle?
  2. Strength.  Can you use that muscle to push, pull, lift and carry?
  3. Basal Metabolic Rate.  The number of calories your body expends at rest.
  4. Bodyfat Percentage.  What percentage of your body is composed of fat?

They named these top four biomarkers, the decisive tetrad.  They are the prerequisites to maintaining healthy numbers in all of the other essential biomarkers.

  1. Aerobic Capacity
  2. Blood Sugar Tolerance
  3. Cholesterol / HDL ratio
  4. Blood Pressure
  5. Bone Density
  6. Internal Body Temperature Regulation

Drs. Evans and Rosenburg coined the term age related sarcopenia in their 1991 book Biomarkers.  It refers to the gradual loss of muscle mass that occurs as we age.  The keys to aging well; staying durable- no injuries, and maintaining control of all health parameters is maintaining or improving muscle mass / strength and eating properly.  An ongoing program of strength training and nutritional discipline are the foremost components of fitness and health.

I was happy to see that Jane recommended her elderly compatriots consume more protein.  Not enormous amounts of protein- just some protein.  Many fitness clients fail to make optimal gains because they have the protein intake of a bunny rabbit.  Adequate training recovery requires the building blocks of muscle in order to produce results.  A bagel for breakfast, a kale sandwich at lunch, a yogurt snack and a diner of soup, bread and ice cream does not supply the nutrients necessary for recovery.

So, take the time to read the amazing Jane Brody and then get those dumbbells out of the basement.
