In the journals

Previous research has suggested that slow walking speed might predict cognitive decline, but a recent study suggests how you walk also may provide clues. The results were published online Nov. 19, 2016, by the Journal of Alzheimer's Disease.

Researchers examined medical records of more than 3,400 people ages 70 to 89 who had completed both a neurological examination and gait analysis to measure walking movements like stride length, step count, cadence, stance time, and arm swings.

Like his father and grandfather before him, the typical American man of the 21st century works for his living. In most cases, though, he works with his mind, not his body.

It wasn't always that way. As recently as the 19th century, 30% of all the energy used in the American workplace was provided by human muscle power; today, the percentage is minuscule. In most ways, the transition from an agricultural economy to an industrial society to today's information age has been a great boon. But something has also been lost.

To help assess your aerobic fitness, here is a minimum standard: See if you can walk up five flights of stairs at your own pace without stopping, using the railing only for balance. The test may seem too simple to be useful, but in the days before sophisticated exercise tests were widely available, thoracic surgeons used this very test to see if their patients were fit enough to undergo lung operations. In modern terms, people who pass the five-flight test have maximum oxygen uptake values of at least 20. That level will get you through surgery and daily life, but healthy people should use exercise to build up to levels two or even three times higher.

It is unlikely that a health club would ask you to use the stairwell for self-assessment, but it might well use a single 12-inch step or bench to evaluate your fitness. With just a little help, you can do it yourself. Ask someone to time you and count for you so you can concentrate on the task at hand (or foot!). At the signal to begin, step up with your right foot, then bring your left foot up beside it. Follow the "up, up" with "down, down" to complete one step. Repeat at a rate of 24 steps per minute for three consecutive minutes. Then rest in a chair for exactly one minute before taking your pulse. Finally, use the YMCA standards (see table below) to see how you stack up.

Some people live long lives with no disease or serious illness. What can they teach you about healthy living?

You won't live forever, but it may be possible to live a long and maybe disease-free life by following the lead of "wellderlies."

This is a term to describe a special group of people who have reached ages 90 to 100 without having any major health issue or disease. And if they do get sick, it often happens late in their life and a short period before death.

High-intensity interval training may be more enjoyable than moderate continuous exercise and may help sedentary adults stay motivated when doing new workouts.

Figuring out the exercise style that best suits your needs will help you stick to a plan.

Making a plan to get regular exercise can be challenging. There are many options, and you may not be sure how to narrow them down. "The result may be that you put off exercising," says Madhuri Kale, a physical therapist at Harvard-affiliated Brigham and Women's Hospital.

It helps to know the basic categories of activity you can choose from: exercise classes, gym workouts, home workouts, and vigorous work or recreational activity. Here are some pros and cons to consider for each.

It appears that the risk of an early death falls with each additional healthy lifestyle behavior that is maintained, even in people who are overweight.

Real-world tracking of exercise habits with a smartphone may inform future cardiovascular research.

Nearly two-thirds of Americans own a smartphone, which comes in handy for instant access to all sorts of information, from driving directions to medical advice. According to a Pew Research Center report, 62% of people have used their phone to research a health condition.

But smartphones can also collect personal health data, aided by apps that track your activity level throughout the day. Because activity and fitness levels are so closely tied to heart health, an accurate assessment of these factors may offer new clues for preventing heart disease.

Cardiorespiratory fitness may soon be considered as a vital sign on par with blood pressure and heart rate.

Three decades' worth of solid evidence linking a sedentary lifestyle to higher risk of cardiovascular disease, cancer, and early death has silenced even the most ardent exercise deniers. Nonetheless, a metric quantifying a person's level of aerobic fitness has yet to make it into the set of tools commonly used to predict heart disease.

But that may soon change. The American Heart Association recently released a statement calling for cardiorespiratory fitness (CRF) to be considered a clinical vital sign, similar to how blood pressure, heart rate, and tobacco use are treated now. Assessing fitness level at your annual visit would help your doctor get a better picture of your underlying heart health and risk of disease down the road.

"Stand up straight." That's timeless advice we've probably all heard at one time or another. It's worth heeding. Good posture is important to balance: by standing up straight, you center your weight over your feet. This also helps you maintain correct form while exercising, which results in fewer injuries and greater gains. And working on balance can even strengthen your abilities in tennis, golf, running, dancing, skiing — and just about any other sport or activity.

Not an athlete? It still pays to have good balance. Just walking across the floor or down the block requires good balance. So do rising from a chair, going up and down stairs, toting packages, and even turning to look behind you.
