Teaching Old Muscles New Tricks (cont.)
The list of health benefits from strength exercise reads like a visit to the fountain of youth. More muscle burns more calories and thus can help with weight control. The increased muscle mass can also help control blood sugar. Strength exercises can improve mood and relieve depression. They can help increase balance, and make getting around a whole lot easier, therefore potentially preventing injury.
Around since the times of ancient Greece, strength exercises are now proving popular among older adults who have learned it's never too late to start.
Preserving Muscle Strength
Muscle strength training can be done by virtually anyone, according to Dr. William Evans, Director of the Nutrition, Metabolism and Exercise Laboratory at the University of Arkansas for Medical Sciences. In research funded in part by NIA, he has shown that frail nursing home residents as old as 98 years (many with multiple chronic diseases) have remarkable increases in muscle strength and size following only a few months of strength training. The results are exciting for scientists because they reveal that even aging skeletal muscle retains its amazing adaptive ability. But perhaps more importantly, the findings have enormous practical significance. Strength gains can lead to greater walking speed, stair climbing power, and balance. An increase in strength can make the difference between being able to get up from a chair by yourself, or having to wait for someone to help you get up.
Strength exercises are one important component of overall fitness. The other components include aerobic exercise, balance and flexibility, which are also featured in the NIA book and video. Helpful hints that answer how much and how often to do strength exercises are listed in "A Word To The Wise". Remember to check with your doctor before starting any exercise program.
Even small improvements in muscle size that you can't see can have a big impact on the quality of your life. Lee, the weight lifting grandma, has already figured this out. She proudly proclaims, "I am an optimist!" as she makes her way to the next machine. With strength exercises, you can add life to your years in addition to adding years to your life.
