16851992Walking is low-risk and easy to start. It can help keep you fit and reduce your risk of serious diseases, like heart disease, stroke, diabetes and more.

A regular walking program can also:

American Heart Association recommends that adults get 150 minutes or more of moderate-intensity physical activity or 75 minutes of vigorous activity each week. Even short 10 minute activity sessions can be added up over the week to reach this goal. If you would benefit from lowering your blood pressure or cholesterol, aim for 40 minute sessions of moderate to vigorous activity 3 to 4 times a week. You could do this by walking 2 miles briskly (about 4 miles/hr). If that’s too fast, choose a more comfortable pace.

Get ready

All you need to get started are comfortable clothes and supportive shoes. Layer loose clothing, keeping in mind that brisk exercise elevates the body’s temperature. Shoes designed for walking or running are best. Make sure you have a little wiggle room between your longest toe (1/2″) and the end of the shoe. Avoid cotton socks since they retain moisture and can promote blisters.

Work on your technique

  • Begin with short distances. Start with a stroll that feels comfortable (perhaps 5-10 minutes) and gradually increase your time or distance each week by 10-20 percent by adding a few minutes or blocks. If it’s easier on your joints and your schedule to take a couple of 10- to 20-minute walks instead of one long walk, do it!
  • Focus on posture. Keep your head lifted, tummy pulled in and shoulders relaxed. Swing your arms naturally. Avoid carrying hand weights since they put extra stress on your elbows and shoulders. Don’t overstride. Select a comfortable, natural step length. If you want to move faster, pull your back leg through more quickly.
  • Breathe deeply. If you can’t talk or catch your breath while walking, slow down. At first, forget about walking speed. Just get out there and walk!

Pick up the pace

To warm up, walk at an easy tempo for the first several minutes. Then gradually adopt a more purposeful pace. A good way to add variety is to incorporate some brisk intervals. For example, walk one block fast, two blocks slow and repeat several times. Gradually add more fast intervals with shorter recovery periods. Concentrate on increasing your speed while maintaining good posture.

Walking hills is a great way to tone your legs. Using Nordic walking poles can help your burn more calories and give you better posture and overall muscle endurance. Treadmill walking, while not as scenic, can be convenient during bad weather.

The end of your walk is an ideal time to stretch since your body is warmed up. Stretch your hamstrings and calves as well as your chest, shoulders and back. Hold each stretch for 15 to 30 seconds.

Track your progress. Although experts recommend walking at least 30 minutes a day, there are no hard and fast rules. Walking 60 minutes/day and brisk intervals will help you burn more calories. Fit walking into your schedule whenever you can. That may mean three 10-minute walks over the course of a day. The best schedule is one that keeps you walking and keeps you fit!

Be safe

  • Avoid traffic accidents. Listening to lively music while you walk is a great way to energize your workout. But if you wear headphones, keep the volume down and watch out for traffic that you may not hear. Wear light colors or reflective clothing and carry a flashlight or glow stick if you walk when visibility is low.
  • Walking on sidewalks is best, but if you have to walk on the street, stick to streets with lower speed limits. Faster streets are riskier because motorists are less likely to see pedestrians and cannot stop as quickly. Accidents involving pedestrians have an 85 percent chance of becoming fatal if the car is moving at 40 mph as compared to only 5 percent if the speed is 20 mph.
  • Know your area. Pay attention to what businesses are open in the area you’ll be walking and know the location of emergency telephones. Walk on well-traveled streets rather than taking shortcuts in less crowded areas such as alleys or parking lots. If you give the message that you are calm, self-assured and have a purposeful gait, you’ll lower your chances of becoming a victim.
  • Two heads are better than one. Walking with a partner or in groups discourages crime and may help alert you to dangers such as speeding motorists or unleashed dogs.

If you experience foot, knee, hip or back pain when walking, STOP and check with your doctor to find out the cause. You may need special exercises or better shoes. If you have osteoarthritis and experience increased joint pain lasting an hour or two after walking, consider an alternate activity like stationery cycling or water exercise. But don’t stop exercising!

8295214_XXLMorning, midday or midnight — when’s the best time to work out?

Well, that depends on when’s the best time for you.

“The best time of the day is when you will do it most consistently, because the benefits of physical activity are tightly linked to the amount you do on a consistent basis,” said Russell Pate, Ph.D., professor of exercise science in the Arnold School of Public Health at the University of South Carolina in Columbia.

Your best time is based on a “constellation” of factors:

  • location,
  • time of day,
  • type of physical activity and
  • social setting, among others.

“It’s not just what time, but what activity, with whom and where,” said Pate, who is also an American Heart Association volunteer. “This mix of factors for people come together to result in being consistent.”

Everybody’s Different

“Different people will have different preferences and predispositions with regard to how they respond to exercise at different times of the day,” Pate said.

For example, if you’re much more likely to work out consistently with a partner, “then you’re better off to opt for a social part regardless of the time of day,” Pate said. “On the other hand, some people like the solitude, the chance to get away.”

You might have heard that the best time to work out is early in the morning — to get your metabolism revving or to avoid unexpected distractions during the day that could derail your regimen. “Are there differences in working out at different times of the day? Maybe. But those differences would be minor compared to the overall effect of doing it consistently,” Pate said.

“If you’re not a morning person, it does no good for you to try to get up at 5 in the morning to work out,” he said. “Try to stack as many cards on your side of the table as possible by doing what’s most likely to work for you. The converse is, don’t make it as hard as it doesn’t have to be.”

Fit in Fitness

The American Heart Association recommends at least 150 minutes (2 hours and 30 minutes) a week of moderate-intensity, or 75 minutes (1 hour and 15 minutes) a week of vigorous-intensity aerobic physical activity. But what if you’re tight on time? Then, be creative and break up your activity into daily bouts of 3-10-minute increments.

For example:

  • In the morning, park 10 minutes away from the job and walk briskly.
  • At lunch, walk 10 minutes in or around where you work.
  • In the afternoon/evening, walk briskly 10 minutes back to your vehicle.

And there you have a 30-minute workout!

“Accumulation across the day doesn’t have to be performed in one bout, but can be across the day,” Pate said. “More is better, but we’re absolutely certain even modest amounts are much better than being sedentary.” And remember, “exercise” is any kind of physical activity that gets your heart rate up for at least 10 minutes at a time.

So get moving — at the time that’s right for you!

16851992Walking is the most popular form of exercise and offers great health benefits, even if it doesn’t burn as many calories as running or other more intense forms of exercise. But a new study has some encouraging news: The equations commonly used to predict the number of calories burned during walking count too few calories in nearly all cases on level surfaces.

Here’s why: Standardized equations commonly used to predict or estimate walking energy expenditure assume that one size fits all. Plus, the equations, which have been in place for close to half a century, were based on data from a limited number of people.

A new study at Southern Methodist University, Dallas, found that under firm, level ground conditions, the most commonly used standards are relatively inaccurate and have significant bias. The standards predicted too few calories burned in 97 percent of the cases researchers examined, said SMU physiologist Dr. Lindsay Ludlow.

A new standardized equation developed by SMU scientists, however, is about four times more accurate for adults and kids together, and about two to three times more accurate for adults only, Ludlow said.

“Our new equation is formulated to apply regardless of the height, weight and speed of the walker,” said Ludlow, a researcher in the SMU Locomotor Performance Laboratory of biomechanics expert Dr. Peter Weyand. “And it’s appreciably more accurate.” Study results, along with the new equation, were published earlier this year in The Journal of Applied Physiology.

“The economy of level walking is a lot like shipping packages,” explains Weyand. “There is an economy of scale. Big people get better gas mileage when fuel economy is expressed on a per-pound basis.”

The SMU equation predicts the calories burned as a person walks on a firm, level surface. Ongoing research is expanding the algorithm to predict the calories burned while walking up- and downhill, and while carrying loads, Ludlow says.

The research comes at a time when greater accuracy combined with mobile technology, such as wearable sensors like Fitbit, is increasingly being used in real time to monitor the body’s status. The researchers note that some devices use the old standardized equations, while others use a different method to estimate the calories burned.

NEW EQUATION CONSIDERS DIFFERENT-SIZED PEOPLE

To provide a comprehensive test of the leading standards, SMU researchers compiled a database using the extensive walking metabolism data available in the existing scientific literature to evaluate the leading equations for walking on level ground.

“The SMU approach improves upon the existing standards by including different-sized individuals and drawing on a larger database for equation formulation,” Weyand explains.

The new equation achieves greater accuracy by better incorporating the influence of body size, and by specifically incorporating the influence of height on gait mechanics. Specifically:

  • Bigger people burn fewer calories on a per-pound basis of their body weight to walk at a given speed or to cover a fixed distance.
  • The older standardized equations don’t account for size differences; rather, they assume that roughly one size fits all.

The exact dates are a bit murky, but the leading standardized equations, known by their shorthand as the “ACSM” and “Pandolf” equations, were developed about 40 years ago for the American College of Sports Medicine (ACSM) and for the military, respectively, Ludlow says.

The Pandolf method, for example, draws on walking metabolism data from six U.S. soldiers, she said. Both the Pandolf and ACSM equations were developed on a small number of adult males of average height.

The new, more accurate equation will prove useful, as predicting energy expenditure is common in many fields, including those focused on health, weight loss, exercise, military and defense, and professional and amateur physical training. Accurate estimations of the rate at which calories are burned could potentially help predict a person’s aerobic power and likelihood for executing a task, such as training for an athletic competition or carrying out a military objective.

In general, the new metabolic estimates can be combined with other physiological signals such as body heat, core temperature and heart rate to improve predictions of fatigue, overheating, dehydration, the aerobic power available and whether a person can sustain a given intensity of exercise.

  • SMU’s new and improved equation for predicting the energy expenditure of walking:
  • VO2total = VO2rest + 3.85 + 5.97·V2/Ht (where V is measured in m/s, Ht in meters, and VO2 in ml O2·kg−1·min−1)

6 Tips for Creating and Sticking to an Exercise ScheduleUsing a heart rate monitor can help get the most out of your workouts and the instant data feedback is a great motivational tool. All heart rate monitors work by measuring electrical signals from the heart and displaying them on the unit’s data center. Chest strap models, which strap to the chest and display data through a wristwatch attachment, are the most accurate. Their proximity to the heart allows for a better reading, and you don’t have to stop moving to check your reading. This data is intended to help ensure your training regimen is not too easy or too intense, but just right for maximum effectiveness.

1) Calculate MHR
MHR= 220-age

Example for a 33 year old
220-33=187 (MHR)

2) Calculate minimum THR
Lower limit = MHR X .60

Example
187 X .60=112 (lower limit)

3) Calculate maximum THR
Upper limit = MHR X .85

Example
187 X .85=159 (upper limit)

The first thing to consider when buying a heart rate monitor is what information you need during your workout. Basic models feature alarms notifying you when you’re out of the desired THR range and is all most people need. Many other features are available such as a stop watch, interval timers, wireless data transfer, training tests, and calorie counter – but they add to the cost. If you know you won’t take full advantage of these features, you can save a good amount of money by choosing a basic unit.

You’d think a simple activity like walking would be just that, simple. But fewer than 50% of American adults do enough exercise to gain any health or fitness benefits from physical activity. Is walking our salvation? I don’t know for sure, but evidence suggests that it’s probably a good start.

What Are the Top 10 Reasons to Walk?

  1. Walking prevents type 2 diabetes. The Diabetes Prevention Program showed that walking 150 minutes per week and losing just 7% of your body weight (12-15 pounds) can reduce your risk of diabetes by 58%.
  2. Walking strengthens your heart if you’re male. In one study, mortality rates among retired men who walked less than one mile per day were nearly twice that among those who walked more than two miles per day.
  3. Walking strengthens your heart if you’re female. Women in the Nurse’s Health Study (72,488 female nurses) who walked three hours or more per week reduced their risk of a heart attack or other coronary event by 35% compared with women who did not walk.
  4. Walking is good for your brain. In a study on walking and cognitive function, researchers found that women who walked the equivalent of an easy pace at least 1.5 hours per week had significantly better cognitive function and less cognitive decline than women who walked less than 40 minutes per week. Think about that!
  5. Walking is good for your bones. Research shows that postmenopausal women who walk approximately one mile each day have higher whole-body bone density than women who walk shorter distances, and walking is also effective in slowing the rate of bone loss from the legs.
  6. Walking helps alleviate symptoms of depression. Walking for 30 minutes, three to five times per week for 12 weeks reduced symptoms of depression as measured with a standard depression questionnaire by 47%.
  7. Walking reduces the risk of breast and colon cancer. Women who performed the equivalent of one hour and 15 minutes to two and a half hours per week of brisk walking had an 18% decreased risk of breast cancer compared with inactive women. Many studies have shown that exercise can prevent colon cancer, and even if an individual person develops colon cancer, the benefits of exercise appear to continue both by increasing quality of life and reducing mortality.
  8. Walking improves fitness. Walking just three times a week for 30 minutes can significantly increase cardiorespiratory fitness.
  9. Walking in short bouts improves fitness, too! A study of sedentary women showed that short bouts of brisk walking (three 10-minute walks per day) resulted in similar improvements in fitness and were at least as effective in decreasing body fatness as long bouts (one 30-minute walk per day).
  10. Walking improves physical function. Research shows that walking improves fitness and physical function and prevents physical disability in older persons.

The list goes on, but if I continued, there’d be no time for you to start walking! Suffice to say that walking is certainly good for you!

New research by exercise scientists confirms that a low-tech, easy-to-administer test is an effective tool for gauging exercise intensity, but that it does not correspond as neatly as previously assumed to other more objective tests. Researchers set out to learn how good the so-called “Talk Test” is and how it compared to two other laboratory-tested measures of intensity, the lactate threshold and the ventilatory threshold.

“If you can still talk comfortably, you’re exercising in a zone that’s appropriate for improving fitness in individuals beginning an exercise program,” Quinn says. “The Talk Test is a good tool, and it’s easy to use.” Continue
