Adults lose, on average, 5 to 10 percent of their muscle mass between the ages of 30 and 50, and an additional 30 to 40 percent between the ages of 50 and 80.
This is why, as beneficial as cardiovascular exercise is, it does not cut it. Weight-bearing exercise is key to muscle mass maintenance, and needs to be integrated into your physical activity routine.
This is not about “bulking up”; it’s about preserving and keeping muscle tissue active and firm.
The increased loss of muscle mass after age 50 helps us understand why so many individuals tend to put on weight during their fifties, even if they consume a diet calorically similar to the one they ate throughout their forties.
Remember, a loss in muscle mass also means a less efficient metabolism. The less efficient our metabolism works, the fewer calories we burn on a daily basis — and the higher our risk of weight gain.
Weight gain, as you know, increases the risk for a multitude of diseases and conditions (from arthritis to diabetes to heart disease).
Once muscle mass wanes, the dominoes cascade down very quickly!
Use it…. or lose it.
