More current studies, using higher intensity workouts have shown that “strength could be doubled in only 12 weeks of training, and that even frail nursing-home residents in their 90’s could build muscle and strength.”
But I Walk and Swim…. Isn’t that Enough to Prevent Sarcopenia?
When most people start a fitness program, they do an aerobic activity, such as walking or swimming, in order to strengthen their heart muscle. But, before one can walk, they must first be able to get out of a chair and maintain an erect posture and balance while walking, and that requires muscle power.
The American College of Sports Medicine, in its guidelines on exercise and physical activity for older adults, says that aerobic conditioning should follow strength and balance training, which is, unfortunately,
opposite of what is usually done. Aerobic exercise, while it strengthens
heart and lungs, is not sufficient by itself to prevent sarcopenia.
It’s easy to understand why older adults participate in aerobic activity for exercise rather than resistance training. Walking doesn’t require a lot of planning to incorporate it into
day, and swimming or biking are familiar activities. Resistance training, however, is less familiar and it requires one to set aside extra time. However, as little as 40 minutes a session, or an hour and a half a week, is enough to see significant results.
According to Dr. Miriam Nelson,
director of
Center for Physical Activity and Nutrition at Tufts University, gains in muscle are probably happening immediately at
cellular level, and in four weeks, one is significantly stronger and may even see less pain with conditions, such as arthritis.
Are there other benefits of Resistance Training?
In addition to building muscle, one also builds vigor and self-esteem, which ultimately leads to one staying active and doing things they enjoy. Preserving muscle mass also impacts
ability to withstand disease. The body burns protein faster than usual, when sick, which then causes protein components to be pulled from
muscle to be delivered to
immune system, to help fight
illness. Sarcopenia reduces
amount of protein available to fight disease.
“If you don’t use it, you’ll lose it.” That saying has never been more true than for
use of our “muscles.” When we lose our ability to use our muscles, we lose independence, and quality of life diminishes. Let’s choose to not take for granted our ability to move around, and incorporate resistance training, into our exercise routine. Length of life is insignificant without quality of life!
