Obesity, Hunger, Inactivity and the Search for Hidden Answers

Hi Readers,

I just received this email from long-time reader and physical educator, David Flax of South Africa. It raises some interesting questions about our perception of the causes of obesity, hunger and lack of activity.

————————–

“Hi Dick,

This is the newsletter written by the Principal of our High School… It is what Prof Tim Noakes had to say. Tim is the leading sports scientist in S.A. and the author of The Lore of Running. A kitkat is the name of a chocolate bar that we have. At most road races the participants are given a goodie bag with wine gums and a kitkat.

If you want to use it you are most welcome to it….Keep well

David”

“Dear King David Community,

Boy Eating CandyThis week 250 school leaders, representatives from over 600 independent schools in this country and some from Australia and the UK, collected in Cape Town at the annual SAHISA conference to compare notes – in both formal and informal forums – on educational best practice. As is often the case, some of the most helpful discussions happened at mealtimes or in the bar before and after meals…

Many of the talks were inspiring, some challenging and I am happy to say that some of them very affirming. One, however, in particular is worth mentioning. It was delivered by professor Tim Noakes, Head of the UCT Exercise Science and Sports Medicine Research Unit and involved a book published in the early 1860s by a very fat undertaker, William Banting. (Banting’s information came from a certain Dr Willian Harvey, who in turn got his ideas from a Parisian, Dr Bernard.) This was the first recorded modern publication to do with a diet based on limiting the intake of refined, easily digestible carbohydrates.

At one point Tim Noakes held up the contents of the little goodie bag we had been presented at the beginning of the conference: a bag of wine gums and a kitkat, simple carbohydrates which he informed us would have so spiked our insulin and disrupted healthy nutrition that we would almost certainly notice a change in our energy absorption and our vitality for the rest of the day. Should we eat that amount of useless calories – he informed us – we could expect to increase our BMI significantly and experience a expansion of our mass by as much as 5kg in three months – just from consuming these two items every day. (I felt chastened – I had eaten the Kitkat before I got to the top of the stairs and the wine gums long before I eventually found my room.)

The really interesting part of Prof Noakes’s discussion though, was to do with the counter-intuitive notion that if insulin production results in one’s body storing as fat the energy presented as simple carbohydrates, the body would not then release this stored energy. This person would then be stimulated to feel hungry – since not enough energy was released. And also because the body was in conservation mode, there would be a significant drop in the fat person’s willingness to participate in physical activity.

Noakes’s point is that fatness causes hunger and lack of activity – and I had always believed that the causal links worked in the opposite direction: that one was fat because one ate too much and exercised too little. Surely this was as obvious as night following day?

On how many occasions did I hear my white-eye browed colleague tell all his pupils that we were lazy or stupid or incompetent, that we just could not…? I now know that he may have often been right, but I also know that he (and many others of his generation) was very often wrong and that he did a great deal of damage to many pupils.

From Noakes’s argument it is no great leap to question our educational models, to re-evaluate how learning happens and to think about what it is that makes a child a happy and successful pupil and a school leaver who takes on the world believing that she can.

There are so many occasions when the obvious and apparent answers not always the correct ones and that as parents and teachers, our job is sometimes think like fat undertakers and to look for processes and functions that are far from the evident. This may be to do with learning styles, recognizing different intelligences in children, helping children to plan or, as in my daughter’s case, simply to stop procrastinating for fear of failure and to get on with the job at hand.”

Can Physical Education Unite a War-Torn Country?

Athletes-Shaking-Hands_webWhen it comes to physical education, it seems that Uganda is more advanced in its thinking than many North American school boards. Rather than firing PE teachers and cutting PE from school curricula, Uganda’s ministry for education has announced that they’ll be recruiting 3600 new physical education teachers over the next two years.

In justifying this expenditure, the minister stated the well-known (but often ignored or misunderstood) rationale of improved health among students.

However, he also  expressed a benefit that is overlooked in North America but is of great urgency in a country with a long history of civil war…unity!

In education minister Kamanda Bataringaya’s speech, he appealed for local leaders to support sport in their districts as a way to unite their communities. In his words: “Very many countries fight each other but when it comes to sports, they are one.”

Fitness, health, national unity.

In Bataringaya’s words,  “So, education should go hand in hand with sports.”

I couldn’t have said it better myself.

The “Sleep It Off” Misconception

Bottles_blog2As we turn the page on another year, I can’t help but think about a tragedy that marked the end of 2009.

Two young men, who had been best friends since childhood, attended a Christmas party where they consumed, as young people often do, a significant amount of alcohol. Instead of driving home inebriated, they did the right thing and stayed over at the host’s house so they could “sleep it off.”

After a few hours of sleep and assuming they were OK to drive, they headed for home the next morning. It was 10:00 AM when they left. Unfortunately, during the drive, they hit a patch of ice and spun into a telephone pole. One of the boys flew out of the windshield and was killed.

The other fellow, whom the police assumed was driving, was tested and found to be still legally intoxicated. In addition to losing his childhood friend, this young man is now going through the court system and may face jail time.

It’s a tragedy for both families and for both boys – they are/were excellent people – the kind of young men you’d want your daughter to marry.

I guess there are two morals to the story. One, always wear your seat belt. Two, sleep isn’t a magic remedy for inebriation. Whether asleep or awake, it takes at LEAST an hour per ounce to metabolize the alcohol in your system, depending on your size and sex. In fact, that process might take even longer when you’re sleeping because your metabolism slows down.

That going to sleep will automatically make you sober when you awaken is a popular misconception and one that PE teachers, as the primary providers of health information in our schools, must contradict. This misconception is so prevalent that morning drive-time is now considered a high-risk time for drunk driving and many police forces set up spot-checks from 6:00 AM to 9:00 AM.

A pre-determined plan for getting home, involving a cab, parent or designated driver, is always the safer option.

I hope the upcoming year is a safe and happy one for you.

Where Are All the Soapbox Cars?

d-editor-soapbox.jpg

My most memorable childhood playthings weren’t factory-made. When I think back, I had the most fun swordfighting with poplar saplings, sliding down snowy slopes on cardboard boxes and playing battleships with homemade graph paper.

I‘ll never forget our day-long sod fights up in the woods—protecting  forts hammered together from old crates and using ammunition made from clumps of grass with dried soil still attached—or the satisfying puff of dirt that signified a direct hit on an opponent’s clean shirt.

But when was the last time you saw a child playing with a soapbox racer made from scrap lumber or a crystal radio set that they had assembled themselves?

Maybe it’s just me, but it’s been quite a while since I’ve noticed any kid in my neighborhood using homemade playthings—such relics have all been replaced by space-age technology from the toy factory.

Nope—a poplar sapling doesn’t stand a chance against a battery-operated Jeddi sword with sound effects and luminous plastic blade. Why rely on gravity to move your soapbox car when a mere $500 will buy you a fully operational miniaturized electrical sports vehicle.  Graph-paper Battleship games are now computerized, and air-powered splatter guns with washable die pellets have replaced our hand-tossed dirt sods. Crystal radio sets have been supplanted by 400 pound boom-boxes with enough power to stuff the Toronto Skydome with thumping, stereophonic sound.

Let’s face it, this is not the decade of do-it-yourself kids.  And while I must confess that I had my share of high-tech gizmos as a kid, including a T-V ping-pong game and a slot car racing track, none of them occupied much of my play-time.

Today, many kids have the attitude that if it isn’t store-bought and doesn’t have a peer-accepted designer label, it isn’t worth using.  And that’s a shame.  Our children are missing the great satisfaction of playing with one’s own creations. And with this, they’re losing the ability to improvise, to innovate, and to create something usable, if not perfect, out of nothing.

Perhaps as physical educators, we should provide more encouragement for creative improvisation. Check the “Equipment” section of the PE Update website and you’ll find dozens of ideas for home-made sports and PE equipment: everything from tin can walkers and 2”x4” balance boards, to garden-hose quoits and  pizza box hurdles. Here are some other ideas—some tongue in cheek and some not— that might improve our childrens’ dearth of plaything creativity:

  • Make MacGyver re-runs required television viewing for all school-age children.  Although our students may never need to know how to make an atomic bomb out of a comb and a lipstick tube, the program’s emphasis on creativity and improvisation is valuable.
  • Allow each student one hour a week in the school dumpster to find materials to build their own game or sports implement.  This “dumpster time” will also reduce the school’s waste output.
  • Provide an extra classification for school waste materials included in blue-box programs.  One box for glass and metals, one for paper products, one for organic material…and one for kids.
  • Use P.E. class as a “market” for your students’ creative efforts.  Sometimes all it takes to get a child’s creative juices flowing is an expressed need for it.  Scoops made from bleach containers, tin-can walkers, home-made hoola hoops, broomhandle aerobics implements—these are all examples of phys-ed equipment your students can make and use in class.

Perhaps our growing awareness of the environment and the trend towards recycling will make home-made playthings more acceptable to young people.  And as teachers, we can use this new attitude to develop our students’ ability to improvise and innovate.

P.S. In case I’ve given you the impression that I was a combination Huck Finn/Thomas Edison as a child, I have a confession to make…I never was able to  get my crystal radio set to work, and I’d personally like a light-saber.

Quality Daily Physical Education
Will Reduce Adult Breast Cancer

blog_girlsexercise_web1.jpg

New research has revealed yet another reason why quality daily physical education is a must for all students. The study, conducted by Dr. Graham Colditz of the Washington University School of Medicine, found that exercise beginning in the teen years can protect girls from breast cancer when they become adults.

The study tracked 65,000 nurses, questioning them about their activity levels starting at the age of 12.

It was found that the women who were active from their teen years through young adulthood were 23 per cent less likely than sedentary women to develop pre-menopausal breast cancer. It was found that the age period that was most important for sustaining activity levels was 12 to 22.
How much exercise? The women with the lowest risk performed three hours and 15 minutes of vigorous exercise, such as jogging or team sport, per week, or 13 hours per week of walking.

It is believed that exercise reduces women’s lifetime exposure to estrogen, one of the hormones that has been linked to breast cancer.

What is the best way to ensure that girls get this exercise and learn the skills they need to continue into adulthood? Mandatory daily physical education classes – taught by professionals whose focus is on lifetime fitness improvement. Make daily exercise mandatory, and teens will participate. And if they exercise on a regular basis, it will become a healthy habit they will continue throughout their lives.

Breast cancer is the leading cause of death among women around the world, with 1.3 million new cases diagnosed every year, resulting in 465,000 deaths.

Be on the Lookout for Students Who Play “The Choking Game”

noose_web.jpg

I have just read about a disturbing activity that may affect students in your school. It’s called the “choking game.” This game has killed at least 82 students in the USA and sent at least 72 Canadian kids to the hospital. In fact, a newly released survey has found that 79,000 students – just in the province of Ontario alone – play this dangerous game.

The survey, called the Ontario Student Drug Use and Health survey, was conducted in 2007 by the Centre for Addiction and Mental Health. Involving Ontario students in grades seven to twelve, it found that seven per cent had played the choking game. There was no difference in participation level between girls and boys or among grade levels.

What is the choking game? Kids either choke themselves – or get someone to choke them – until they begin to pass out. This state of oxygen deprivation produces a temporary feeling of euphoria. The game has other names: the scarf game, space monkey, the pass-out game, blackout and five minutes to heaven.

However, it is easy to go too far with this game and a slight miscalculation can be deadly.

What signs may alert teachers to students who are playing the choking game? Bloodshot eyes, frequent headaches, marks on the neck, and the possession of strange items such as ropes, collars and dog leashes.

As Physical education teachers, you are in a position to prevent a tragedy. You can discuss this game and its dangers during health classes. And the T-shirts that students wear in class will expose marks on a student’s neck that is an indicator of game-play.
