When Walking Burns More Calories Than Running

Sunday, August 7, 2011 1 comments

A writer from Runner's World magazine got to wondering about burning calories while walking versus running. Her experiment discovered something interesting about the two cardio activities.

Wearing a heart-rate monitor she ran on the treadmill at 6 different speeds. Then after a brief rest she repeated the experiment walking this time. She discovered that as the pace exceeded 5 mph, or a 12-minute mile, walking became harder than running as shown by her heart rate. Admittedly, walking above 5 mph is very difficult, but if it is easier on your joints don't feel bad that you are not running with the others. Walking at fact paces "forces your body to move in ways it wasn't designed to move," thus increasing internal friction.

Obviously, faster running burns more calories but walking is still a great way to burn off calories. The point is to do something that challenges you without leaving you exhausted. Check out the RunKeeper app for your iPhone to track your speed and calorie burn for your exercise. Read the full article for most interesting ruminations on calorie burn and exercise

As slick devices take over our home and homes away form home, whispers of techno-health hazards keep flying. We get to the bottom of what's real, what's not, and when to opt out.

Smartphones

The situation: Just as we were chatting on our iPhones about oursummer plans, the news broke: The World Health Organization had just classified radio frequency waves — the radiation we know most from cell phones — as "possibly carcinogenic." No new studies were hatched, just a review of existing relevant research, which led to a conclusion of "limited evidence" for certain brain tumors from cell phones — meaning there "could be some risk" and we should "keep a close watch." But alas, the ongoing wishy-washiness stems from the existing studies' being too small, too outdated, and too ill-designed to be definitive, explains Michael Wyde, Ph.D., of the National Toxicology Program. The strategy: Minimize exposure. Read more here.

iTunes Alert
Now that smartphones have replaced iPods, they're also wreaking havoc on our ears. Overworked sensory cells die and leave behind scar tissue, resulting in an errant hum and dissipating hearing. To slow the decline, listen no longer than 90 minutes a day at 80 percent of maximum volume, and trade earbuds for noise-canceling headsets to avoid turning up the volume. Read more here.

Wi-Fi Router
The situation: Can the technology that powers our Internet connection — and our lives — be the reason behind our blahs? Indeed, Wi-Fi routers emit radio frequency waves, just as cell phones do. And while we don't press them against our head, their emissions are constant and ubiquitous. Physiologists report that electromagnetic fields (EMFs) produce a biochemical stress response in cells, and some say this can, in the short term, cause those hodgepodge of symptoms known as EMF sensitivity, and, in the long term, make us vulnerable to inflammatory diseases and cancer. The strategy: Unplug your home router and avoid public places with Wi-Fi when you're not using it. Read more here.

iPad, E-Reader
The situation: Not that we're complaining, but what happened to those incessantiPad commercials? Holding up the iPad forces wrist- and finger-extension, leading to repetitive strain injuries (RSIs), says Frances Pisano, founder of ergoblog.com. Laying the iPad flat forces you to lower your head, which strains the neck. The strategy: Prop up the screen with a rack or books. Bend your neck forward no more than 15 degrees, and look down with your eyes, not head. Read more here.

GPS
The situation: If you're seeing crazier driving these days, it may be because drivers' brains are shrinking. As research out of the Douglas Mental Health University Institute in Montreal suggests, road maps encourage us to pay attention to our surroundings, to learn street configurations, to figure out where we are in relation to our target destination (a.k.a "spatial strategy") and force us to exercise the part of our brain called the hippocampus. But when people navigate by simply doing as instructed ("stimulus-response strategy") — as they might do with a GPS — the hippocampus was less active. Read more here.

Laptops
The situation: From Georgia to Kansas, headlines have breathlessly reported on laptops that "bursted into flames!" And sure, it gets hot under there, but tremendously more common are burn injuries and heat rash — or, as the October issue of the journal Pediatrics called it, "toasted skin syndrome," which feels like a sunburn. The strategy: A docking system is best from adermatologic and ergonomic perspective. Read more here.





6 Sneaky Ways To Get In Exercise

0 comments

Need to work out but can't get to the gym? Try these six easy ways to work out! The best part? You can do these moves anywhere!

At-home chair squats: Hover above a chair seat as if you were going to sit down, without letting your butt or thighs touch the seat. Hold for 30 seconds, building up to 1 minute. Do these body toning exercises whenever you get a moment, aiming for once an hour.

Squat in the Kitchen: Every time you're in the kitchen, perform triceps dips using a kitchen chair: Stand in front of a chair as if you were going to sit down, then bend knees and lower hips, placing hands on the seat edge, fingers pointing forward, arms straight. Walk feet forward, and with feet flat and torso erect, bend and straighten arms, keeping butt close to chair seat without touching it. Do 8-15 reps.

Shopping squeeze: As you push your shopping cart, or whenever you're walking, contract your butt muscles as tightly as you can and keep them contracted as you walk. (No one has to know!)

Commercial crunches: Anytime a commercial comes on while you're watching television, do an ab exerciseof your choice until the show you're watching returns; pick a new ab move for each ad.

Telephone walk: Whenever you're on a cellular or cordless phone at home, walk around for the duration of the conversation. (Wear a pedometer and see the steps add up!)

Balancing act: When you brush your teeth, or while standing at the kitchen sink, lift one leg slightly and bend and straighten your standing leg to perform one-legged squats . Tighten your buttocks and keep your abs contracted as you squat. After 10-15 reps of these body toning exercises, switch legs and repeat.

Avoid the Weight Gain Trap

0 comments


The never-ending fight against weight gain sometimes seems like a lost battle. One minute you're devastating the competition -- eating healthy and fighting off junk-food cravings. The next, you're back on the ropes, muttering to yourself, "I can't believe I ate that whole thing." For some, it's emotions and circumstances that can wreak havoc on a diet, whether it's a breakup, stress or pure boredom. For others, it's a never-ending cycle of new diets that promise results too good to be true and abs that look airbrushed.

No matter what trap you find yourself in, there's always a way out.


The Trap: Emotional Eating

If the words "emotional eating" bring to mind an image of a disheveled Bridget Jones toting a pint of Ben & Jerry's, think again. Emotional eating is not just inhaling spatula-fuls of Cherry Garcia between post-breakup sobs. In reality, 95 percent of eating is emotional, says Beth Castle, an emotional eating expert in Alberta, Canada. And when emotions such as stress, grief or boredom lure you into the kitchen, you're stuck in one of the most suffocating weight traps of all.

"When people are looking for comfort, it's easy to turn to food," Castle said. "In that moment, it makes them feel better." But as soon as you finish that slice or two or three of molten chocolate lava cake, you feel even worse than you did before. The very thing that was supposed to relieve your distress makes it even worse -- sparking a vicious cycle that only ends in extra pounds.

"We need to find something to fulfill our needs other than food," Castle said, emphasizing that social interaction is key and that "laughing is often the best comfort." Sometimes, just going for a walk outside can help take your mind off food's temptations.

The most important thing to do when you fall victim to emotional binging is to forgive yourself, says Kathie Mattison, an eating disorders therapist in Rockford, Illinois. Punishing yourself for falling off the weight-loss wagon will only make the struggle worse. The moment you forgive yourself is the moment you can start taking steps to improve your relationship with food, she says.

Sometimes, it's nearly impossible to overcome emotional eating alone. If you think you may be depressed, or if your stress starts to take over your life, Mattison says the best thing to do is see a therapist or doctor.


The Trap: The Clean Plate Club

"Finish your peas." On the surface, it's a simple request that your parents might have said every night at dinner. But underneath, it reflects America's portion problem, and it's one of the most indestructible warriors in America's battle with food.

The Clean Plate Club has its roots in a World War I campaign by President Woodrow Wilson to ensure the country's food didn't go to waste. Schoolchildren were asked to sign a pledge: "At table I'll not leave a scrap of food upon my plate. And I'll not eat between meals, but for suppertime I'll wait."

Almost a century later, many are still devoted members. Though the U.S. supply of food is far from scarce, many Americans still find themselves adhering to the traditional three-meals-a-day schedule. If you limit yourself to a certain number of meals a day, Castle says you're more likely to overeat. When you save your appetite for supper, you'll probably finish that calorie-packed plate of lasagna entirely.

Castle recommends eating several smaller meals instead of carving your day around breakfast, lunch and dinner.

"The goal is not to plan what you eat; the goal is to have a variety of healthy foods and snacks," she says.

Notorious for their never-ending bowls of pasta, restaurants are one of the most delicious foes in the portion-control fight. If you have trouble putting down the fork when dining out, Castle suggests sharing meals or ordering from the kids' menu.


The Traps: The Diet-and-Binge Cycle and Nighttime Eating

You might skip breakfast, cut out carbs or even survive a week solely on cayenne pepper and molasses. Skipping meals or cutting out food groups -- techniques promised to help "drop 5 lbs. in two weeks" or "say goodbye to belly fat" -- can leave your blood sugar imbalanced and your appetites unsatisfied.

"By ignoring our bodies' signals of hunger and fullness, food is disconnected from the body's needs," Mattison said. And when you finally respond to your need to eat, you're more likely to lose control.

These habits can make you susceptible to two of the most common traps: the diet-and-binge cycle and nighttime eating. "If we skip meals, graze, keep going with caffeine throughout the day, at night we'll be hungry, fatigued and craving food satisfaction," Mattison said.

The key to avoiding both of these traps is not skipping meals and making sure you don't go hungry throughout the day, Castle and Mattison say.

"The afternoon snack is key to making better decisions at night," Castle said, adding that a piece of fruit or a cup of coffee won't cut it. She suggests having some carbs, whole grains and protein. "By the time 5 o'clock hits, we're more likely to make better decisions about what we're having that night."

Supermarket Smarts: Ditch The Basket, Choose A Cart For Healthier Groceries

0 comments

One of the easiest ways to eat healthier is to simply ban your "bad foods" from your house. You may crave junk food, but chances are you wouldn't leave your house for it (most of the time). But the tricky part of that trick is that it's hard not to buy the bad stuff at the supermarket to begin with. (Rules about shopping while hungry are cliche, but true: On an empty stomach, I always come away with a cart full of crackers, cheese, and beer.) Researchers have found one incredibly simple way to make less unhealthy food choices at the grocery store: Push a cart instead of carrying a basket.

Weight Loss: Are Fancy Grocery Stores Better for Your Health?

You might guess that carts would encourage more impulse shopping (more room for potato chips!), but apparently flexing your arm to pick up your basket at the store entrance "leads to a preference for vices over virtues, and for smaller, earlier rewards over larger, later monetary rewards," according to a study published in the Journal of Marketing Research. Does this seem absurd to you? I mean, really, how truly bizarre. Will researchers now test whether placing baskets atop a table or something, so customers have to reach up for them instead, might work out? Will supermarkets discourage basket stacking so one has to lean further, flex more, to pick a basket up—what impact would that have on increasing impulse buys?

Scary Study: 72% of Grocery Carts Are Covered In Fecal Bacteria

The study is part of a field of research called embodied myopia, in which "seemingly irrelevant bodily actions influence consumer behavior," and apparently there is a whole body of research showing the flex/reward tie and other weird body/behavioral connections. For a little help choosing mangoes over chocolate bars during grocery trips, try reaching for a cart no matter how small your intended shopping load: Shoppers were three times more likely to choose candy over fruit if they carried a basket!
