Drs. Evans and Rosenburg are Tufts University researchers interested in the measurable parameters that keep humans healthy and fit over an entire life span. They have determined that the top four biomarkers are:
- Muscle Mass. The percentage of your body that is made of muscle.
- Strength. Can you use that muscle to push, pull, lift and carry.
- Basal Metabolic Rate. The number of calories your body expends at rest.
- Body fat Percentage. What percentage of your body is composed of fat.
The authors named these top four biomarkers, the decisive tetrad. They are the prerequisites to maintaining healthy numbers in all of the other essential biomarkers.
- Aerobic Capacity
- Blood Sugar Tolerance
- Cholesterol / HDL ratio
- Blood Pressure
- Bone Density
- 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.
