Staying in Shape as You Age
Will you be hale and hearty in your golden years or dependent on others? The answer greatly depends on how physically active you are.
Many older Americans do not get enough exercise to maintain good health. This presents a problem as the normal aging process slowly takes its toll. With each passing decade after age 50, we lose muscle strength and heart function. These losses come from a combination of factors, like poor nutrition, hormone changes, and declining muscle and nerve cells. But the main cause of dwindling independence as we age is usually a sedentary lifestyle.
The good news is that —no matter what age you are—you can still make gains in cardiovascular and musculoskeletal fitness. So, it is never too late to start reaping the rewards of more exercise.
Many Benefits From Exercise
At any age or level of ability our bodies need regular physical activity to function well. Here are just a few of the major benefits of exercise:
Recommendations for Getting Fit
Exactly how much exercise do older adults need to achieve good health? The American College of Sports Medicine (ACSM), the American Heart Association (AHA) and the United States Department of Health & Human Services makes the following general recommendations on the types and amounts of exercise for healthy adults aged 65 and older:
Also, if you have a chronic condition, work with your doctor to find out how you can safely incorporate exercise into your life.
Precautions Before You Begin
Since physical activities can stress your body and heart, check with your doctor before starting a program. For sedentary or minimally active older adults who plan to start a vigorous exercise program, some experts advise an exercise stress test. But, many doctors reserve exercise tests for people with chest pain or major risk factors for heart disease.
Besides getting your doctor’s advice, it is wise to do what you can to guard against injury. Here are some simple safety measures you can take while exercising:
If you take sensible precautions to avoid injury, exercise can give you the strength and energy to do the things you enjoy as you age.
