Lifting weights is becoming more and more popular in today’s society. Although fitness tends to be more popular among the younger generation, fitness is still important to the older generation. We researched the ways aging affects strength.

1. The Cross Sectional Area of Muscle (CSA)

Muscle size is heavily tied with muscle strength. Nonlifters tend to lose muscle mass as they age, primarily fast twitch (type II) fibers. However, studies showed that lifting weights will help retard muscle loss. Bodybuilding also shows that muscle mass can also be accomplished at any age. Dexter Jackson (47 years old) is a Mr. Olympia champion and came second for this year’s Olympia against a much younger lineup. More muscle mass also keeps your metabolic rate high, keeping you from getting fat as you age.

2. Maximal Strength

As humans get older we lose maximal strength(the max amount of weight we can lift). For men, its estimated that you lose about 10 to 20% of your max strength level as you age. However, much like CSA, this can be prevented by lifting as you get older. A look at any Master Olympic weightlifting or powerlifting meet shows that age can be just a number. Many records in powerlifting and weightlifting are set by lifters over 30.

One thing that keeps older people from lifting is the fear that they are too “brittle” and “old” to lift safely. However, a study done by Boston Rehabilitation Center showed that elderly (86-96) who began lifting showed increases in muscle mass and strength. The researchers also stated that strength exercises would help prevent falls, the most common injury for the elderly.

3. Nervous System

As people age there is also a decrease in the infrastructure of the central nervous system(CNS). As study in 1991 stated that there is a 37% decline in spinal cord connections and a 10% decline in nerve conduction speed as one ages. Other studies have pointed out that the loss of CNS structure and muscle fiber connections is due to the lack of proper conditioning from intense exercise.

Conclusion

Our research showed that one does lose strength as they age. They lose CSA, maximal strength, and CNS structure. However, all these losses can be lessened by lifting at both a young age and older age.

The research also surprisingly showed that lifting was not dangerous to the elderly, but could actually diminish their injury rate. On top of this, many powerlifting and weightlifting records are set by lifters over 30 while bodybuilding shows that one can be competitive at any age.

Lifting is not a young people’s game, do not fall into the mentality that you have missed your best years to start lifting. The best time to start weight training is now!
