Aging Stressor: The Muscular System

/in /by

Sarcopenia is the number one issue that impacts muscles—that’s the loss of skeletal muscle mass and strength that comes with age. It can begin as early as the 20s in some and accelerates once we pass 60; it’s thought to be primarily due to the genetics of aging. There’s also little question that a sedentary lifestyle contributes to muscle loss. Losing muscle mass impacts not just strength, but also stamina, posture, balance, and the ability to move your body.

There are several types of muscle fibers, but they all appear to become slow-twitch fibers as we age. And they get smaller. However, and this is important, they don’t ever seem to go away completely. Strength training has been shown to be effective even for people who are 100 years old; they get stronger, which helps deal with all those issues I mentioned before. The research hasn’t demonstrated that muscles will get larger, but most studies end at three to six months, which is too soon to really judge results; it’s probably going to take more than six months to gain back what we lost over many decades.

The key to dealing with sarcopenia is strength training—the earlier in life the better, but it’s never too late. Strength training can encompass many approaches from doing squats by standing up from sitting in a chair (using a walker if balance is an issue), push-ups and other calisthenics, and weight training using bands, tubes, machines, and free weights.

There are hundreds of programs and thousands of exercises to help build strength using every modality. I think it should all begin with an evaluation by a healthcare professional to test posture and balance, as well as strength. The next step is to see a physical therapist who can evaluate your limitations and put together a plan to get you started safely; it’s hard to keep your positive attitude if you get hurt right away and need to pause. Once you get approval and a plan to train, then getting muscles prepared is important. Calisthenics, which include chair exercises for those with arthritis, are a good place to begin.

Final memo before Christmas on Tuesday with one more place to attack when we’re aging with a vengeance.

What to Do About Aching Joints

/in /by

When we stop to consider what prevents us from moving as much and as freely as we would like, the main culprit would probably be our joints: knees for most, with hips a close second. Shoulders are up there, along with our feet and hands. One of my problem areas is my thumbs in the metacarpal joints of both hands.

Everything we’ve talked about so far leads us to our joints. The muscles attach to bones via tendons across joints, and that allows for movement. There are ligaments that hold bones in place, several types of cartilage that provide cushioning, even specialized fluid within joints. It’s the interaction of all those factors combined with the damage we’ve experienced and our genetics that results in the pain we may experience that inhibits motion. What do we do about it?

Without question, the most important is stretching and strengthening. I’ve written about that already, but it warrants a reminder. Maintaining the range of motion of each joint improves our mobility and ability to use our limbs properly. Our physical therapist has a saying, “Motion is lotion,” which is a way of saying the more you move, the easier it is to move. We should all move as much as we can without overdoing it. Here’s an example: Paula and I had to give up dance lessons because she has arthritis in her feet, and dancing was just too much stress on all the little joints in the foot. For all of us, the challenge is finding that happy medium between moving enough to keep everything going and moving so much it adds to the damage.

In terms of nutrients, all parts of the joints are connective tissue; the basic nutrient for every one is glucosamine. Our bodies are supposed to make as much as we need but often don’t. Any type of glucosamine can be beneficial. Chondroitin and hyaluronic acid are forms of glycosaminoglycans. In addition, vitamin C is also important for all connective tissue. There are many nutrients that may impact the inflammation in joints such as tart cherry juice and turmeric. But it begins with a good foundation, and that’s glucosamine.

Everything to date leads us to the final part of this series of living every day. I’ll cover that on Saturday.

What Counts: Exercise or Movement?

/in /by

This week is planting week around the house, so Paula and I will be working around the yard each day. What we won’t do is go to the gym to work out. In thinking about it, that raises the issue of the myth of physical activity: does yardwork count or do you have to get your heart rate to a certain amount?

The answer is it all counts. In fact, if your lifestyle forces you to move a couple of times an hour, all day long, that’s associated with living longer. We’ve lost the equivalent of 700 calories of daily activity due to technological advances in the past century; those are calories that contribute to the weight gain that’s been creeping up on us. We could cut 700 calories from our daily diet or we can find ways to use another 700 calories every day. Anything and everything you can do to use calories throughout the day counts. Gardening and yardwork definitely count in that process, and as the image shows, it’s movement you can pass on to future generations.

We’ll look at a food myth on Thursday.
