Preventing Muscle Loss as We Age

Sarcopenia, a decline in skeletal muscle in older people, contributes to loss of independence.

“Use it or lose it.” I’m sure you’re familiar with this advice. And I hope you’ve been following it. I certainly thought I was. I usually do two physical activities a day, alternating among walking, cycling and swimming. I do floor exercises for my back daily, walk up and down many stairs and tackle myriad physical tasks in and around my home.

My young friends at the Y say I’m in great shape, and I suppose I am compared to most 77-year-old women in America today. But I’ve noticed in recent years that I’m not as strong as I used to be. Loads I once carried rather easily are now difficult, and some are impossible.

Thanks to an admonition from a savvy physical therapist, Marilyn Moffat, a professor at New York University, I now know why. I, like many people past 50, have a condition called sarcopenia — a decline in skeletal muscle with age. It begins as early as age 40 and, without intervention, gets increasingly worse, with as much as half of muscle mass lost by age 70. (If you’re wondering, it’s replaced by fat and fibrous tissue, making muscles resemble a well-marbled steak.)

“Sarcopenia can be considered for muscle what osteoporosis is to bone,” Dr. John E. Morley, geriatrician at Saint Louis University School of Medicine, wrote in the journal Family Practice. He pointed out that up to 13 percent of people in their 60s and as many as half of those in their 80s have sarcopenia.

As Dr. Jeremy D. Walston, geriatrician at Johns Hopkins University School of Medicine, put it, “Sarcopenia is one of the most important causes of functional decline and loss of independence in older adults.”

Stop Chronic Injuries

Tennis can be tough on your body!  Just ask Federer, Nadal and the typical club member at Manly Lawn.  It’s been cold, wet and windy in Sydney for Badge — the perfect recipe for injury!

At some point, particularly as we age, our injuries become chronic — and our recovery time between play becomes longer. The result: we play less and, even more, are less inclined to play!

For chronic injuries, the Guys from Trident may be able to help you like they did for me — and my bum shoulder. Their methodology — small, targeted interventions to keep you moving,  is similar to the Carrolls, the tennis trainers, who used to keep me on the courts in California.  US Nationals are typically five day events on brutal hard courts, so you needed all the help you could get to make it through to finals day — if you were good enough.

For the rest of us, here’s a link to a series of warm-up and cool-down exercises that were created specifically for tennis players to stop injury or discomfort before it begins.  I have used a variation of Pete’s exercises for many years to continue to play competitively — here’s an example.

I can attest that these exercise, when done regularly, will help you feel more agile, relieve any joint or muscle tightness, and ensure that you are ready for most shots that comes your way — so you can play tennis for life!

Wishing you good health and tennis for life,

This is what exercise/tennis does for your brain

I’m not shy in my advocacy for exercise as a therapy for mental health. It’s something I talk about often, something I’ve experienced first-hand, a topic I’m passionate about, and over the past few years, something I’ve continued to research and strived to understand better.

This is what I’ve learnt – the human brain is fascinating and we’re continuing to discover more about its capabilities every day. We certainly don’t know all there is to understand about the connection between physical exercise and mental health, but I hope you’ll agree, moving our body is something our brain wants and something our mind can hugely benefit from.

Here’s just some of the reasons why.

It releases feel good chemicals in your brain

Most of us will have heard of endorphins – the ultimate “feel good” chemicals that our body releases when we exercise. Endorphins are what we can thank for that blissful ‘post-exercise high’ that often follows a good sweat session. These chemicals interact with the receptors in our brain that reduce our perception of pain and trigger a positive feeling in the body. Endorphins help to reduce stress and anxiety, but when we exercise, there are other mood boosting chemicals at play as well.

Exercise also increases the production of serotonin in the brain, which works as a natural antidepressant. Lastly but certainly not least important, exercise increases the production of dopamine – the “motivation” and “reward” brain chemical.

With a knock-on production of endorphins, serotonin and dopamine, it’s no surprise regular exercise is linked with enhanced mental health and emotional wellbeing!   

It can improve your concentration

Research supports the idea that exercise improves focus, attention, and the ability to concentrate. But how?

When we exercise, especially at a high-intensity where our heart rate is elevated, our adrenal glands and our brain ramp up production of a chemical called norepinephrine. As more norepinephrine flows into our bloodstream, it increases our alertness and focus. An important reason to prioritise exercise during busy working periods, to improve productivity!

It can boost your memory

A number of studies show that aerobic exercise (aka cardio) promotes brain growth, especially in the hippocampus area, the part of our brain that is associated with memory1,2,3.

And if that‘s not enough to convince you – a new study from McMaster University in Canada found that young adults who participated in 6 weeks of high intensity interval training (HIIT) experienced significant improvements in their memory and recall4.  

It can slow cognitive decline

Keeping physically fit can also help to keep our brain healthy as we age. Exercise stimulates the release of growth factors, chemicals in the brain that affect the health of brain cells, the growth of new blood vessels in the brain, and even the survival of new brain cells. These growth factors help to protect our brain against injury and preserve our cognitive function5,6.
