Nurons in the brain

Nurons in the brain


A neuron in the brain.
Researchers at Princeton University recently made a remarkable discovery about the brains of rats that exercise. Some of their neurons respond differently to stress than the neurons of slothful rats. Scientists have known for some time that exercise stimulates the creation of new brain cells (neurons) but not how, precisely, these neurons might be functionally different from other brain cells.

In the experiment, preliminary results of which were presented last month at the annual meeting of the Society for Neuroscience in Chicago, scientists allowed one group of rats to run. Another set of rodents was not allowed to exercise. Then all of the rats swam in cold water, which they don’t like to do. Afterward, the scientists examined the animals’ brains. They found that the stress of the swimming activated neurons in all of the brains. (The researchers could tell which neurons were activated because the cells expressed specific genes in response to the stress.) But the youngest brain cells in the running rats, the cells that the scientists assumed were created by running, were less likely to express the genes. They generally remained quiet. The “cells born from running,” the researchers concluded, appeared to have been “specifically buffered from exposure to a stressful experience.” The rats had created, through running, a brain that seemed biochemically, molecularly, calm.

For years, both in popular imagination and in scientific circles, it has been a given that exercise enhances mood. But how exercise, a physiological activity, might directly affect mood and anxiety — psychological states — was unclear. Now, thanks in no small part to improved research techniques and a growing understanding of the biochemistry and the genetics of thought itself, scientists are beginning to tease out how exercise remodels the brain, making it more resistant to stress. In work undertaken at the University of Colorado, Boulder, for instance, scientists have examined the role of serotonin, a neurotransmitter often considered to be the “happy” brain chemical. That simplistic view of serotonin has been undermined by other researchers, and the University of Colorado work further dilutes the idea. In those experiments, rats taught to feel helpless and anxious, by being exposed to a laboratory stressor, showed increased serotonin activity in their brains. But rats that had run for several weeks before being stressed showed less serotonin activity and were less anxious and helpless despite the stress.

Other researchers have looked at how exercise alters the activity of dopamine, another neurotransmitter in the brain, while still others have concentrated on the antioxidant powers of moderate exercise. Anxiety in rodents and people has been linked with excessive oxidative stress, which can lead to cell death, including in the brain. Moderate exercise, though, appears to dampen the effects of oxidative stress. In an experiment led by researchers at the University of Houston and reported at the Society for Neuroscience meeting, rats whose oxidative-stress levels had been artificially increased with injections of certain chemicals were extremely anxious when faced with unfamiliar terrain during laboratory testing. But rats that had exercised, even if they had received the oxidizing chemical, were relatively nonchalant under stress. When placed in the unfamiliar space, they didn’t run for dark corners and hide, like the unexercised rats. They insouciantly explored.

“It looks more and more like the positive stress of exercise prepares cells and structures and pathways within the brain so that they’re more equipped to handle stress in other forms,” says Michael Hopkins, a graduate student affiliated with the Neurobiology of Learning and Memory Laboratory at Dartmouth, who has been studying how exercise differently affects thinking and emotion. “It’s pretty amazing, really, that you can get this translation from the realm of purely physical stresses to the realm of psychological stressors.”

The stress-reducing changes wrought by exercise on the brain don’t happen overnight, however, as virtually every researcher agrees. In the University of Colorado experiments, for instance, rats that ran for only three weeks did not show much reduction in stress-induced anxiety, but those that ran for at least six weeks did. “Something happened between three and six weeks,” says Benjamin Greenwood, a research associate in the Department of Integrative Physiology at the University of Colorado, who helped conduct the experiments. Dr. Greenwood added that it was “not clear how that translates” into an exercise prescription for humans. We may require more weeks of working out, or maybe less. And no one has yet studied how intense the exercise needs to be. But the lesson, Dr. Greenwood says, is “don’t quit.” Keep running or cycling or swimming. (Animal experiments have focused exclusively on aerobic, endurance-type activities.) You may not feel a magical reduction of stress after your first jog, if you haven’t been exercising. But the molecular biochemical changes will begin, Dr. Greenwood says. And eventually, he says, they become “profound.”

Just Do IT

Just Do IT…. A lesson we all can learn from! leave your comments.

An Apple a Day Keeps the Dr Away. :)

Apples have always been a staple in my home. My children eat them any time of the day or night. I often give thanks for this because they’re super convenient – no sticky fingers, no need to peel and they don’t squash in the schoolbag. And, as a health conscious mother, they tick all the boxes when it comes to a healthy snack – portable and easy to eat like other snack foods but without the added fat and sugar.

But does the proverbial apple a day really keep the doctor away. Apple eaters get a decent dose of fibre, some vitamin C and small amounts of B vitamins in a low calorie (kilojoule), low GI package. Apples are also loaded with anti-oxidant compounds called flavonoids (as are tea, onions and red wine) and are a significant source of quercetin and catechin. It’s these antioxidant compounds primarily in the skin that are thought to be responsible for apple’s health benefits – so wash them and eat them skin and all.

How does all this translate into health benefits? Research has found that people who eat three or four serves of fruit a day, particularly apples and oranges, have the lowest overall GI and best blood glucose control. While, large-scale studies published in recent years have also shown that eating apples is linked to a reduction in heart disease, diabetes, asthma and some types of cancer (lung, bowel and breast).

For example, the 2007 Women’s Health Study found greater intakes of flavonoid rich foods like apples (along with red wine and pears) are associated with a reduced risk of heart disease among post-menopausal women.

With so many of us needing to trim our tummies, eating an apple a day could put us on the path to shedding pounds without pangs. January GI News reported on a study that showed how feel full foods that you have to chew a lot (apples, carrots, pearl barley, muesli, very grainy breads, lean meat) satisfy appetite faster and keep you feeling fuller for longer. While a study published in Appetite by researchers at Pennsylvania State University found that ‘eating whole fruit (in this case a peeled apple) at the start of a meal can be an effective strategy for increasing satiety and decreasing energy intake at a meal.’ People who ate a whole apple about 15 minutes before lunch, consumed almost 190 fewer calories (around 800 kJ) at lunch than when they didn’t have the apple.

Crunch time In a world where eating for health can easily become complicated and costly, it’s good to know that something so naturally sweet and filling will help you enjoy a lifetime of healthy benefits.

A Twist on Spaghetti

If you’re having trouble working vegetables into your meals have no fear–this pasta look-alike is here to help. Spaghetti squash, a winter variety, is actually quite mild-tasting on its own. This recipe uses tomatoes and onion to impart rich flavor without taking away from the unique texture of the squash. And squash is a nutritional powerhouse, containing Vitamin A, potassium and fiber.

Spaghetti Squash with Fresh Tomato Sauce
• 1 small spaghetti squash (about 2 lbs.)
• 2 lbs. vine-ripe tomatoes (small beefsteak, Early Girl or plum varieties)
• 1 Tbsp. extra virgin olive oil
• 1/2 cup finely chopped onion
• 2 garlic cloves, finely chopped
• Pinch of dried red pepper flakes
• 1/2 tsp. salt
• 1/2 tsp. dried basil
• 1/2 tsp. dried oregano
• Freshly ground black pepper
Preheat oven to 375 degrees. Pierce squash in half dozen places with a thin knife. Bake squash on a piece of foil in oven until it yields slightly when firmly pressed, about 50-60 minutes.
Meanwhile, peel tomatoes using a swivel-bladed vegetable peeler with serrated blade. Halve, seed and dice tomatoes.
Heat oil in medium skillet over medium-high heat. Add onion and sauté until translucent, about 4 minutes. Mix in garlic and cook another 2 minutes, stirring constantly. Add tomatoes, red pepper flakes, salt, basil and oregano. Cook, stirring until tomatoes are tender (but still hold their shape), about 5 minutes. Season to taste with black pepper.
Halve the baked squash horizontally. Scrape out and discard the seeds. Using a fork, scrape out the squash in strands. Divide four cups of the squash among four deep pasta bowls. Spoon one-fourth of the sauce over the squash in each bowl. Serve immediately.
Makes 4 servings.

21 Universal Rewards of Exercise

21 Universal Rewards of Exercise
The number one reason that most people are out-of-shape is that they don’t exercise enough.

I’ve often wished that I could give each and every one of you a personalized pep talk to get you up off the couch and into the gym, day after day. So here’s my pep talk in bullet form – 21 rewards that you will gain from regular exercise.

Do yourself a favor and print this list and post it where you’ll see it every day. When you need motivation or encouragement simply read over this list and feel your motivation soar.
1. You’ll reset your body: Exercise has been described as a giant reset button. A good workout will block appetite swings, improve your mood and even help you sleep.
2. Your clothes will fit better: Consistent exercise will tone and tighten your body, causing your clothes to not only fit better but to also look nicer. Also exercise ensures that soon you’ll be trading your clothes in for smaller sizes.
3. You’ll be less stressed: You have enough stress in your life – it’s time for a break. A good workout invigorates your muscles, leaving you relaxed and less stressed.
4. You’ll have more energy: WebMD tallied research studies and concluded that 90% of them prove exercise increases energy levels in sedentary patients. Next time you feel fatigued, fight it will the most powerful tool available: exercise.
5. You’ll be stronger: Exercise improves muscle strength and endurance, two things that you use throughout each day. When you exercise consistently you’ll be pleasantly surprised when difficult tasks begin to seem easy.
6. You’ll be less likely to binge: Exercise has a powerful anti-binge effect on the body. This is due in part by an increase in sensitivity to leptin, a protein hormone, which has an appetite-taming effect.
7. You’ll burn calories: You know that excess body fat is made up of stored and unused calories. Fight back by burning loads of calories with fat-blasting workouts.
8. You’ll be more confident: Who doesn’t wish they walked and talked with more confidence? A consistent exercise program will do just that. As your body becomes more fit, watch as your confidence sky-rockets.
9. You’ll have fun: Believe it or not, exercise can be extremely enjoyable. Remember how fun it was to run around as a child? Tap into your inner child as you find a mode of exercise that gets you excited.
10. You’ll reduce your blood pressure: Exercise has been proven more effective than medication in reducing blood pressure to normal levels. A single workout has been shown to reduce blood pressure for the day and regular exercise reduces overall blood pressure in the long run.
11. You’ll lose the jiggles: Regular exercise tightens flabby arms, legs and waistlines. So wave goodbye to the jiggles with a solid exercise program.
12. You’ll increase insulin sensitivity: Researchers at Laval University in Quebec discovered that exercise improved insulin sensitivity dramatically. Peak after-meal insulin levels dropped by more than 20 percent after as little as 3 weeks of consistent exercise.
13. You’ll sleep better: Do you toss and turn for hours before falling asleep? Exercise is a powerful sleep aid. Your tired muscles encourage your body to quickly fall asleep so they can get their overnight repair work done.
14. You’ll lower your risk of heart disease: Regular exercise strengthens your heart and makes it more resilient against disease. A sedentary lifestyle is a major risk factor for heart disease, so rest assured that consistent exercise is your ally against disease.
15. You’ll feel great: Vigorous exercise releases natural endorphins (happy hormones) into your blood stream that dissolve pain and anxiety. You’ve probably heard of ‘runner’s high’, this can be achieved by any great workout.
16. You’ll lower your risk of diabetes: Studies show that exercising as little as half an hour each day can dramatically reduce your risk of diabetes. If you are at risk of diabetes, or already have diabetes, regular exercise is the most effective treatment for reversing the disease.
17. You’ll meet cool people: You could benefit from a group of new, energetic friends, right? Gyms, bootcamps, workout centers and even the jogging trail are all great places to connect with fun new friends.
18. You’ll improve your BMI: You know that maintaining a healthy BMI is key in disease prevention. Exercise is the best way to keep your BMI under control.
19. You’ll increase your endurance: Do you ever get out of breath when walking up stairs or through the mall? Regular exercise builds your endurance for everyday activities.
20. Your doctor will be impressed: How many times has your doctor given you the lecture about losing weight and exercising more? Exercise regularly and get your MD off your back!
21. You’ll look amazing: Are you happy with the shape and size of your body? Regular exercise works wonders on your physique. Within a few weeks you’ll see shape and tone in all the right places.
What are you waiting for? Lace up your shoes and get moving!

Being taken out of your comfort zone

Alright today is not going to be my usual type of correspondence.

I just want to share some great news with you that it’s been a truly AWESOME past couple weeks here at Personalized Fitness & Nutrition!  I hope I can send some of these ‘good vibes’ your way.

Why am I so pumped up this morning?

This past week we’ve received no less than 8 wonderful, heartfelt e-mails, letters, and cards from clients we’ve been working with for some time.  Just look at the client results!  Scroll down to May 2nd..  You can do this people the only thing different from them to you is that they were people who followed through with their committment to live that higher quality of life.

ALL of them are just ROCKING IT right now.

And the list of success stories goes on, and on, and on.

Our clients are just killing it. Dont be left out and be featured on our next website!

And we couldn’t be more proud of em’.

 

Their secret is not some whiz bang new ’shiny thing’ or some magic pill. They’ve simply been quietly and methodically, studying, implementing, and refining everything we teach them about how to build a successful fitness lifestyle over the last several months (and couple years in some cases).

 

Reminds me of 2 sayings I’ve had drilled into me over and over again my entire life.

 

“Hard work pays off”

 

“Tough times don’t last, but tough people do”  Thanks Dad!

 

It doesn’t matter where you are today, or what you’re dealing with at the moment that may seem like a ‘crisis’ right now. You can and will RISE ABOVE IT!

If you just stay focused, work hard, YOUR time will come…. and when it does, oh boy, are you in for a well deserved rocket ride.

It might take a few weeks, a few months. or a few years…. but it WILL happen.

You have the power to create the future you want for your business, your life, and your family.

And it’s our pleasure to continue supporting you in any way we can to make that happen.

 Here’s to a great week and I hope this message gives you a ‘pick me up’ today if you needed one.

To your success,

Mark

 

P.S. One more thing and word of advice. If you’re frustrated with where you’re at today, then congratulations. That’s a GOOD thing! Train with higher intensity LESS Talk, and adhere to the nutrition and water prescription.

 

Because that frustration and discomfort will fuel you to continue working hard and accomplish what is necessary to grow.

 

One of my favorite quotes from Benjamin Franklin is “The best thing we can do for the poor is make them so uncomfortable in their poverty that they have the desire to grow beyond it”

 

So.. if you’re uncomfortable with your current circumstances… GREAT!

 

Use that energy as fuel to grow!

As a reminder this is Memorial Day Weekend.  Please remember to be safe and some back healthy next week.  We will be closed on Monday but will train as usual on Friday and Saturday!

 

 Happy Birthday Shawn….  (one of my brothers) I dont think he reads this though..  :)
