Healthy Aging Means Exercising
Your muscles need to work.
When you were younger, running a marathon, jogging a 10K three times a week or playing tennis or squash may have been enough to give you a firm foundation for a healthy life. As you get older, the emphasis shifts from building the foundation to protecting the structure.
Don’t get me wrong. Aerobic activities are still important for strengthening the heart and lungs, keeping your weight down, managing you blood pressure and the other illnesses that face middle-aged and older people.
Without exercise, however, your muscle power fades with age. Actually your strength starts to decline in your 30s and it’s downhill from there. Between the ages of 50 and 70 your strength can decline by as much as 15 percent each decade and accelerate from there. It’s that decline that is responsible for the weaknesses and disabilities associated with old age.
There are aging experts who say you could substitute strength training on some days for aerobic exercise. I personally do aerobic exercise daily and add on at least 2 days of strength training and stretching often with a personal trainer. On days when I’m primarily doing aerobic exercise, I’ll also work out with weights for about 10 to 15 minutes, primarily with my upper body.
As a woman, and a petite one at that, I need strength building and maintenance more than men my age. First because I have less muscle mass than a man so whatever I muscle cells I lose will impact me more.
Secondly, strengthening my muscles fortifies the bones and women are at increased risk of osteoporosis. Risk of bone loss and fractures rise sharply in women during and after menopause. Strength training helps prevent bone loss because lifting weights stresses the bones as well as the muscles stimulating the cells.
As strength training workouts builds muscle you increase the proportion of muscle to fatty tissue. Because muscle cells burn calories faster than fat, the more muscle I add, the more I will boost my metabolic rate and burn more calories and burn them faster.
I am a firm believer that keeping up with the strength training just makes my life that much easier. I’m strong enough to lift chairs around, shovel and plow the snow, help carry boxes of books at a book sale and hang onto my grandchildren once I chase them down.
