I received a number of questions in response to the last Smart Bite on telomeres and their effect on cellular aging including this one:

Do telomeres respond to strength training?

While the current research does not specifically link resistance training, like weight lifting, to increased telomere length, it’s important to note that telomere length is only one indication of healthy cells.

Strength training is more important than ever as we age. In addition to firming and toning which make us look good, strength training has these health benefits:

It helps us maintain our resting metabolic rate (RMR) by building muscle. The RMR affects how many calories we can eat per day. Without strength training, this most likely will decrease year after year.
It makes our bones stronger through weight-bearing exercise.
It improves functional movement, giving us the strength and agility to bend, kneel and reach for things without injury.

Whether you’re a veteran or a novice at strength training, you can always try something new and appropriate for your fitness level. Next week’s Smart Bite contains specific suggestions for people who travel or don’t have access to equipment.
