Yet another study supports what we know …

Another study that supports what we already know: that those who exercise  are in better health than those who don’t.

Cycling and exercise for health

82-year-old Norman Lazarus, a professor emeritus at London’s Kings College, requested that a study be performed on the health of older active cyclists. King’s College and the University of Birmingham took him up on it. Researchers compared 125 amateur cyclists, ages 55 through 79, with a group of people ages 57 through 80 and with a younger group ages 20 through 36. All of the noncycling group were healthy but did not exercise regularly.

Lazarus had noted that he and his riding group were not experiencing many of the frailties, such as joint problems or chronic illness, that affect so many other people as they age. His group had been avid cyclists for most of their lives.

Less evidence of aging in cyclers

The researchers found that those who exercised – in this case cycled – regularly did not show evidence of the outward signs of aging.

The male cyclists in the study had to be able to ride 62 miles in 6½ hours, and females had to be able to ride 37 miles in 5½ hours, according to the study, published in the journal Aging Cell. I’m not a cyclist but seems like a fairly intense regimen.

Less loss of strength

In a series of lab tests, researchers found cyclists did not lose muscle mass and strength like the noncyclists did. The cyclists also stopped the clock on increased body fat and cholesterol, and the men’s testosterone levels remained high.

Improved immune systems

One of the most surprising findings was that the cyclists’ immune systems were equivalent to those of healthy young people in the study, as measured by the presence of immune cells, known as T-cells. The cells are produced by the thymus gland and typically start to decrease as the thymus begins to shrink after age 20. Depleted immune systems are one of the greatest barriers to health in the elderly.

Intense exercise is the key

We know from other studies that cycling is not the important part of this – the intense exercise is.

The CDC recommends that adults get 150 minutes a week of moderately intense exercise or 75 minutes of vigorous exercise.

The moral

The moral here – do something! It’s better than nothing. And even if you can’t do even moderately intense exercise now, you soon will be! So get moving!

“Best Exercise for Aging Muscles”

I saw that headline and sat back. Yeah, I guess that’s me! Aging muscles… Sounds kind of rude. Accurate but rude!

As we get older, it’s true, cells deteriorate. So what can we do to slow that progression down or even stop it?

Use it or lose it!

There are lots of studies out there that prove this. I’m not going to bore you with statistics. But, you know – if your knees get stiff you’ve got to get up and walk around. If you’ve pulled something in your back, you know your doctor told you not to rest – get up and move! It’s harder to lose weight too as we age. Yes, eating less is imperative, but so is movement!

As I’m writing this I feel myself slumping. I wrote about this last week – every few minutes I have to think about sitting up straight and pulling in my stomach. Once an hour it’s helpful to get up, walk around, drink some water. It’s good to get your body moving and it’s good to hydrate!

And, if you really want to help your muscles and your mind – because lots of studies have also shown that exercise helps keep your brain young – do a focused period of exercise. Intense exercise is better than leisurely, but any exercise is better than nothing!

An exercise program that you like – or at least find interesting – is better than one you don’t like. You’ll stick with it and get better results from the program. My running is the exception – I run a couple of times a week on the treadmill to improve my speed and endurance for dog agility. I still hate it. But I do it because I know it does help. And I’m starting to get better at it. I do enjoy the audio books I listen to while I run, and that certainly helps keep me motivated to run.

Exercising in an hour? Have a cup of coffee!

It’s not just for breakfast any more! Coffee can improve your workout, researchers have shown. Researchers conducted a study in which a sample of inactive men were monitored biking with and without caffeine. While the men said they put forth the same amount of energy whether or not they had consumed caffeine, the results revealed faster cycling rates after caffeine consumption. Another set of researchers conducted a study and found participants who had caffeine before a workout had an easier time holding back cravings. In fact, those who had caffeine ate 72 calories less after the workout than those who hadn’t consumed the stimulant.

I don’t think it’s surprising. The caffeine in a cup of coffee will boost your energy and help you stay awake, so it’ll give your workout a boost too. You don’t even realize that you’re working harder. If you’re not sleepy, then you can pedal (or run) faster. The caffeine also boosts your stamina – letting you work longer, getting in that extra mile (or half-mile for me!)

Heidi Skolnik, a sports nutritionist, also says that coffee also increases the release of dopamine and other feel-good neurotransmitters. So you can work past what you might otherwise perceive as pain or weakness. The benefit of coffee to your workout starts about an hour after you drink it.

Now, don’t go crazy! Putting in lots of cream and sugar or other calorie-laden additions might taste really good, but the extra calories will outweigh any benefits the caffeine will give you. A little milk is good though – the protein and carbohydrates it adds will help kick-start your brain!

And remember to drink water while you’re exercising. It’s important to stay hydrated, and coffee alone won’t do that! Get a good night’s sleep, and drink plenty of water and you’ll get the most benefit from your workout.
