A great video to watch and share. Well worth the time. It’s about 9 minutes total. It’s also a great follow up to my post about the Hotter than Hell ride I did this summer.
Is It Better to Walk or Run?
May 31, 2013 by
Walking and running are the most popular physical activities for American adults. But whether one is preferable to the other in terms of improving health has long been debated. Now a variety of new studies that pitted running directly against walking are providing some answers. Their conclusion? It depends almost completely on what you are hoping to accomplish.
If, for instance, you are looking to control your weight — and shallowly or not, I am — running wins, going away. In a study published last month in Medicine & Science in Sports & Exercise, and unambiguously titled “Greater Weight Loss From Running than Walking,” researchers combed survey data from 15,237 walkers and 32,215 runners enrolled in the National Runners and Walkers Health Study — a large survey being conducted at Lawrence Berkeley National Laboratory in Berkeley, Calif.
Participants were asked about their weight, waist circumference, diets and typical weekly walking or running mileage both when they joined the study, and then again up to six years later.
The runners almost uniformly were thinner than the walkers when each joined the study. And they stayed that way throughout. Over the years, the runners maintained their body mass and waistlines far better than the walkers.
The difference was particularly notable among participants over 55. Runners in this age group were not running a lot and generally were barely expending more calories per week during exercise than older walkers. But their body mass indexes and waist circumferences remained significantly lower than those of age-matched walkers.
Why running should better aid weight management than walking is not altogether clear. It might seem obvious that running, being more strenuous then walking, burns more calories per hour. And that’s true. But in the Berkeley study and others, when energy expenditure was approximately matched — when walkers head out for hours of rambling and burn the same number of calories over the course of a week as runners — the runners seem able to control their weight better over the long term.
One reason may be running’s effect on appetite, as another intriguing, if small, study suggests. In the study, published last year in the Journal of Obesity, nine experienced female runners and 10 committed female walkers reported to the exercise physiology lab at the University of Wyoming on two separate occasions. On one day, the groups ran or walked on a treadmill for an hour. On the second day, they all rested for an hour. Throughout each session, researchers monitored their total energy expenditure. They also drew blood from their volunteers to check for levels of certain hormones related to appetite.
After both sessions, the volunteers were set free in a room with a laden buffet and told to eat at will.
The walkers turned out to be hungry, consuming about 50 calories more than they had burned during their hourlong treadmill stroll.
The runners, on the other hand, picked at their food, taking in almost 200 calories less than they had burned while running.
The runners also proved after exercise to have significantly higher blood levels of a hormone called peptide YY, which has been shown to suppress appetite. The walkers did not have increased peptide YY levels; their appetites remained hearty.
So to eat less, run first.
But on other measures of health, new science shows that walking can be at least as valuable as running — and in some instances, more so. A study published this month that again plumbed data from the Runners and Walkers Health Study found that both runners and walkers had equally diminished risks of developing age-related cataracts compared to sedentary people, an unexpected but excellent benefit of exercise.
And in perhaps the most comforting of the new studies, published last month in Arteriosclerosis, Thrombosis and Vascular Biology and again using numbers from the versatile Runners and Walkers Health Study, runners had far less risk of high blood pressure, unhealthy cholesterol profiles, diabetes and heart disease than their sedentary peers. But the walkers were doing even better. Runners, for instance, reduced their risk of heart disease by about 4.5 percent if they ran an hour a day. Walkers who expended the same amount of energy per day reduced their risk of heart disease by more than 9 percent.
Of course, few walkers match the energy expenditure of runners. “It’s fair to say that, if you plan to expend the same energy walking as running, you have to walk about one and a half times as far and that it takes about twice as long,” said Paul T. Williams, a staff scientist at Lawrence Berkeley National Laboratories and the lead author of all of the studies involving the surveys of runners and walkers.
On the other hand, people who begin walking are often more unhealthy than those who start running, and so their health benefits from the exercise can be commensurately greater.
“It bears repeating that either walking or running is healthier than not doing either,” Dr. Williams said, whatever your health goals.
For confirmation, consider one additional aspect of the appetite study. The volunteers in that experiment had sat quietly for an hour during one session, not exercising in any fashion, neither running nor walking. And afterward they were famished, consuming about 300 calories more than the meager few they had just burned.
25 Ways to get Healthier Now!
April 10, 2013 by
(CNN) — Get going! Here are 25 ways to get healthier right now:
1. Grab your toes. Now pull. “This boosts circulation after your feet have been cramped in shoes all day,” says Michele Summers Colon, a podiatrist in El Monte, California. “Without proper circulation, the muscles and nerves in our toes don’t work properly. And that can cause pain in your knees, hips, and back.”
2. Wash the linens. Dust mites, a major allergy trigger, love to hang out in your bed. Zap ’em by laundering sheets and pillowcases every week in hot water. Also smart: Use mattress and duvet covers designed to keep mites out.
3. Flying? Turn on the air vent above your seat. “I fly a couple of times a week,” says Dr. Travis Stork, an emergency medicine physician and co-host of “The Doctors.”
“Part of the way I stay healthy is by being very conscientious about all of the germs that are on planes. I turn on the air vent and angle it so it blows air down in front of my face — that’s filtered air and it creates a little bit of a barrier to keep the germs going around the cabin from getting into my nose or mouth.”
4. Give this a shot. Get a yearly flu vaccine? Great. Now add a TDaP booster to your arsenal. TDaP stands for tetanus, diphtheria, and pertussis — and that last disease, also known as whooping cough, is a particularly dangerous respiratory illness. In fact, cases of pertussis in the U.S. have risen about 137% since 2000.
“For most adults, that means a nasty cough; in children, it can be worse,” says Dr. Ana Pantoja, staff physician for AltaMed in Boyle Heights, California. “So if you have kids or are around kids, it’s essential to get vaccinated.”
Even if you got the shot as a child, its effectiveness can wear off, so you still need one booster as a grown-up. (You’ll also need a tetanus booster every 10 years.)
5. Drop your panties. Going commando once in a while (say, overnight) couldn’t hurt, especially if you’re prone to urinary tract infections.
“Wearing no undergarments — or just cotton ones — allows the external genitals to dry and reduces bacteria growth that could otherwise make its way into your urethra and cause a bladder infection,” says Dr. Sherry Thomas, an OB-GYN and surgeon at St. John’s Regional Medical Center in Oxnard, California.
6. Keep this info handy. Put a card in your wallet that lists any allergies you have and medications you’re taking, in case you end up in the ER and are unable to speak for yourself.
Says Dr. John M. Kennedy, co-author of “The 15-Minute Heart Cure,” “It could just save your life.”
7. Crank down the volume. MP3 players can create sound up to 120 decibels — loud enough to cause hearing loss over time.
“Follow the 60/60 rule: Keep volume coming through your headphones to no more than 60% of the max, for no more than 60 minutes a day,” says James Foy, an osteopathic physician in Vallejo, California.
5 days of healthier breakfasts
You already know it’s important to start your day off right — now it’s time to kick it up a notch nutritionally with these easy ideas from Jackie Newgent, author of “1,000 Low-Calorie Recipes.” Just add…
8. Flax. Sprinkle one tablespoon ground flaxseed in your bowl of oatmeal for brain-boosting omega-3 fats and two extra grams of fiber.
9. Pistachios. Spread toast with chocolate nut spread; add chopped pistachios for cholesterol-lowering phytosterols.
10. Berries. Top pancakes or waffles with ½ cup of mashed raspberries to get more than 20 percent of your daily vitamin C needs.
11. Turmeric. Toss a pinch of ground turmeric into beaten eggs to add earthiness and cancer-fighting antioxidants to a veggie omelet.
12. Hummus. Schmear half a toasted whole-grain bagel with 2 TBSP hummus for a creamy topping packed with fiber and filling protein.
13. Nuke the dish sponge. “This is the germiest thing in your house,” says germ guru Charles Gerba, a microbiologist at the University of Arizona in Tucson. “About 15% of sponges contain bacteria that can make you ill.“
So toss them in the dishwasher once a week or microwave them damp on high for 30 seconds.
14. Check yourself out. “Do a full-body skin check once a month in a well-lit room,” advises Dr. Joshua Zeichner, director of cosmetic and clinical research at Mount Sinai Medical Center in New York. “Grab a hand mirror if you have one. Ask a family member to check out your back if you can’t see it. Look for new moles or old ones that have changed or grown (then have a dermatologist take a look).
“I also recommend a total-body check with a derm yearly — twice a year if you have a personal or family history of funny moles. Early detection is key in treating skin cancer” — the most common cancer in women.
15. Munch on carrots. The humble carrot never got much attention, but it’s now a nutritionist favorite, thanks to its high vitamin A content — just one half cup has almost double the amount you need for healthy eyes. They’re hot with chefs, too, making it easier to get your good-vision fix.
16. Wear an activity tracker. Whether it’s a Fitbit, a Nike FuelBand, or any old pedometer, studies show that people who wear a device that tracks the number of steps they’ve taken each day get moving more than those who don’t.
17. Take a ticker test. You may not think about your cholesterol, but you should: Having high numbers is a major heart-disease risk factor that even slim women can have.
Thanks to the Affordable Care Act, you may be able to score a screening without paying one cent for it if you have a family history or other risk factors, according to Kathleen Sebelius, secretary of the U.S. Department of Health and Human Services.
18. Fight daylight savings blahs. When we “spring forward,” the lost hour can have a bigger effect on our bodies than we might think.
“You might feel jetlagged, and it can take two to five days to adjust,” says Dr. Meir Kryger, professor of medicine at Yale University. His fix: “Get some sunlight as soon as possible” — by raising window shades or making a coffee run — “to help re-synchronize your body clock. Luckily, the switch-over happens on a Sunday morning, so many of us don’t have to go to work that first day!”
19. Get comfy. “At hotels, I keep lighting soft and bring lounging clothes and my Dream Sack, a thin, silk sleeping bag. On planes, I close the shades and wear an eye mask and noise-cancelling headphones or earplugs.” — Tracy Cristoph, flight attendant
20. Banish nerves. “When my mind starts racing in bed, I think about the next day’s challenges. Then, I take long breaths, thinking, Breathe in, breathe out. It takes practice, but if you do it regularly, your body learns how to relax.” — Rebecca Soni, Olympic swimmer
21. Silence your phone! “I alerted friends and family to when I would be sleeping so I could minimize noisy calls and texts. Turning the phone off works, too!” — Dr. Marni Hillinger, a medical resident in New York.
4 ways to slash stress in 60 seconds or less
22. Do 25 jumping jacks. Move your body, no matter how briefly, to stop the stress response in its tracks and change the channel on your mood, says Lisa Oz, author of “US: Transforming Ourselves and the Relationships That Matter Most.”
23. Press “play” for puppies. Pets are a proven stress-buster, but you knew that. Head to Wimp.com/littlepuppy stat to melt even the gnarliest of bad moods.
24. Make an instant hot cocoa. Research, including a study published in Appetite, shows that even a bit of chocolate can boost your mood almost immediately.
25. Go outside! “Fresh air is full of feel-good negative ions, which may boost oxygen flow to the brain,” says Kathleen Hall, founder of the Stress Institute in Atlanta. “If you can, combine it with exercise, like a brisk walk — activity boosts endorphins and energy.”
