Some have called strength-training the best anti-ager that we have! Why such a strong statement?
Miriam E. Nelson’s research created news worldwide when the results were published in the prestigious Journal of the American Medical Association. After a year of strength training twice a week, women’s bodies were 15 to 20 years more youthful.
Without the use of drugs, they regained bone density, which helps prevent osteoporosis. They became stronger – in most cases even stronger than when they were young.
Their flexibility and balance improved. Without changing what they ate, they were leaner and trimmer. What’s more, the women in this study were so energized that they become 27% more active.38-39
The anti-aging benefits are found in men also. A study revealed that persons unable to walk at a normal pace, experienced physical limitation in other areas as well, such as doing heavy housework (washing the car, raking leaves, mowing the lawn, or cleaning up the garage), lifting something ten pounds, walking half mile, walking up a flight of stairs, dressing, eating, and bathing. The study concluded that in order to remain independent as you get older, it is vital to maintain good muscle strength.40
The book Biomarkers: The 10 Determinants of Aging You Can Control, vividly illustrates how strength training is a fountain of youth.
The ten determinants that you can control are your muscle mass, strength, basal metabolic rate, body fat percentage, aerobic capacity, blood-sugar tolerance, cholesterol/HDL ratio, blood pressure, bone density, and your body’s ability to regulate its internal temperature. Every one of these determinants is directly and significantly affected by strength training.41
The most obvious determinants affected are muscle mass and strength, the immediate results of this important component of physical activity.
