As we age we gain wisdom, but each passing birthday also brings a progressive loss of muscle strength, muscle mass, and aerobic capacity. We’ve known for some time that strength training can help preserve, or even rebuild, muscle mass and strength, but now a new study shows that aerobic activities, like walking, swimming or biking, can also help.
Canadian scientists recruited over 70 men and women who were either inactive or highly active from three different age groups: 20-39; 40-64; and 65-86. Researchers put each group through a series of tests, and found that compared to the sedentary adults, those who regularly engaged in aerobic exercise performed better on evaluations of grip and muscle strength.
The take home message is: just get moving. While this study doesn’t mean strength training isn’t necessary, it does support the old “move it or lose it” principle, and demonstrates that regularly getting your heart rate up can help you hang onto muscle. And that can translate into a reduced risk of injuries, greater independence, and a dramatic improvement in quality of life.
If you’ve been inactive and you’re not sure where to start, consider putting on your walking shoes. Here are 10 reasons why I think it may just be the perfect form of exercise.
