Sport Is Unrelated To Obesity In Children

xiox writes "The UK government is planning to stop funding a study to understand obesity in children. The study fits children with accelerometers to measure how much energy each child uses in a day by moving. The results are surprising. Those children who do sports at school do not burn more calories than those who don't. Furthermore there is no correlation between body mass index and the number of calories used! The results are very interesting, suggesting that genetics and diet are the main reasons for childhood obesity, not sport. The UK government is trying to increase the amount of sport in schools."

    Even if sports don't help children keep slim, it is proven that it helps adults (in addition to genetics and diet, of course). People who start out as active young children are probably more likely to stay active into adulthood, at least moreso than less active kids. So in that sense, by teaching kids to exercise and be fit, you will potentially increase adult fitness. This alone justifies fitness programs in school.

      Not correct for the subject in hand. The subject is UK schools .

      This morning I dropped of junior at school and I noticed a big sign: No play in the playground allowed, dangerous BIG holes in the playground. There were two holes, both 1-2 inch wide, 1 inch deep. For the reference the school is Queens Edith Primary in Cambridge UK.

      The way UK schools (based on observations from the same school) understand physical education is - you put kids in class, tell one to do an exercise, the rest watch. There is a variation on this when you show the exercise and they do it. There is no warmup whatsoever. If a child decides to warm up by doing a run around for 5 minutes he is penalized and chastized as a troublemaker. Compared to that on the continent they make them all run for at least 200m in the under 10 age group, going to 600+ for the older ones at the beginning of the lesson. As a result the exercise value in the UK is minimal and it is actually hazardous from a health and safety perspective as the children have had no warmup.

      In addition to that in the UK all other obesity related factors are obscured by one other - vitamin D defficiency past the nursery age. 95% of the kids show bone deformations characteristic for that - X legs, rachitic skull, the lot. The primary reason for this is the anti-sun + suncream obscession which leads to most kids getting less than the essential doze of sun for activating vitamin D to the required degree (30min daily average unhindered summer sun at UK lattittude for an average white caucasian, going up to 1h+ in spring, autumn and winter, with the numbers for darker skin colour being bigger than that). Add to that the fact that kids are ferried around in buggies restrained with minimal movement till the age of 4 and the picture is mostly complete (mine refused to get into it from the age of 2 and I agreed with him).

      From there on kids are bound to be obese. Until these factors are eliminated any study in the UK will be bogus as a large sample of the juvenile population is already highly susceptible to obesity and no physical education or sport can help them in that. Nothing to see people, move along. Another study which concentrates on everything but the two root causes for UK:

      • The rabid propaganda by the UK cancer research soscieties about skin cancer will kill by an order of magnitude more people from vitamin D defficiency related causes like bone problems and obesityt, than it will save.
      • The UK pram obscession is the other main reason for obesity. Get the kids out, they are not a damn toy doll to ferry around.
      Stating either of these is too unpopular so people do studies on everything but these.

    While this may show interesting correlations, the fact remains that if more calories are burnt than are consumed, the body will lose weight.

    When kids exercise more, they also eat more, and the body tries to retain the same reserves while burning off more calories. Eating no more, or just a little more, will be fine and the subject will still lose weight.

    It's when the eating leads to significantly ore eating that there is a problem.

    So, exercise and diet are required. But that isn't news. We've known this for quite some time.

  3. Maybe sports in school takes fun out of exercise by Latent+Heat · · Score: 5, Interesting
    Perhaps some gym class/athletic programs/sports in school manage to promote sports elite and take the fun out of such activities for the majority of the other kids.

    If the emphasis is on competition and winning, the vast majority of school children don't belong to the few that are advanced a few months in maturation and have the muscle strength to dominate in these competitions and thereby most warm the bench. At all levels from the gym class through the "revenue sports" of high school football (yes, they charge money to watch these kids play football), the emphasis is on winning rather than having a rotation to keep as many kids involved, or even providing any degree of remedial sports training to offer any degree of encouragement or extra support for the kids who don't dominate their sports teams.

    There may be some cultural or social reasons for the less athletically gifted to try out for sports teams and be part of the team even if they play a minor supporting role, but the whole sports culture is a kind of primate dominance hierarchy thing rather than focused on keeping as many people physically fit.

    Also, I don't know if the Latin teacher is a frustrated Classics scholar, the English teacher is a frustrated attorney, or if the Math teacher is a frustrated research engineer (although the Physics teacher, if you had that subject, was always a little beyond the fringe), but the Gym teacher is most likely a frustrated athlete given the very broad pyramid of people attempting to make a career out of sports with a chosen few at the very tippy top.

    The childhood obesity epidemic is an epidemic of news stories, not a problem itself.

    Horseshit. When I was in school 20 or so years ago, you could count the number of fat kids (in a school of 2300 students) on your fingers, and a child who would be considered obese by today's standards was virtually unheard of. At my kids' schools, it's easier to count the kids who aren't fat than the ones who are, and there's at least one obese kid in any group larger than about ten.

    I know it's all the rage to pretend that whatever problems our society causes itself don't actually exist, but this one is pretty easy to nail down. Anybody who says we don't have a serious problem with kids and their poor eating habits and lack of activity is either an idiot or a liar.

    excellent article, thanks for linking it. Seems I never have mod points when I want/need them. I started by cutting hydrogenated oils out of my diet, I'm working on high fructose corn syrup. I'm not 100% on either one, but I'm making conscious choices to cut back on both. I know this will be blasphemy on this site, but Mountain Dew contains "brominated vegetable oil". Gatorade, a "health" drink contains "glycerol ester of wood rosin". Tell me honestly, is there any way you would put that in your body if it wasn't hidden in some mile long ingredient list?

    Watching my 10 year old niece grow up, I can say with some certainty, that obesity is at least in part, a learned behavior. She has been fed a steady diet of fast food and sweets, and is essentially instructed to "sit in front of the TV while Mommy does something else". Watching her morbidly obese mother sneak food and gorge herself to find solace has only reinforced negative eating habits. My wife and I took her skiing last weekend and she lied to me about her weight. 10 years old and she is ashamed of how heavy she is. She was almost in tears when my wife and I explained to her that for her own safety, she had to tell us what she weighed so her ski bindings could be set properly.

    Being someone who works with an organization that promotes mass participation physical activities for children I can say that you have touched on a key issue. Physical activity with the pairing of the benefits of a healthy diet should be promoted and not the concept of sport that pits child against child and team against team. Sport is good but encouraging everyone to engage in a general healthy lifestyle which should include moderate to vigorous physical activity is key. And on a final note before I took up my job at this organization I was a "physical education" teacher (we prefer that over gym teacher, we are teaching a subject not a room) and I wasn't a frustrated former athlete and though there is a percentage of former athletes who become PE teachers, its not as high as you think.

    Well children burn calories like mad even at rest. If for nothing else, they're always growing and that takes significant energy.

    While I have not read all the /. comments yet, I hope we do not damn the study simply because the results were not what we expected. That's the whole reason we're supposed to be doing studies in the first place. Rubber stamping desired outcomes is what corporate sponsored studies are for.

    Let me make sure I understand this. Your evidence that sports make you lose weight is that you weighed less when you were 17 than you did when you were 22.

    I was curious and happened to have an old package of "maruchan" ramen in my pantry. One package is 400 calories with 16g of fat, 8 of which are saturated fat. (FYI it is also 60% of your daily sodium intake!)

    Anyway, you claim a gain of 35lbs over 6 months. That's ~183 days. According to wikipedia, 1lb of fat gain is roughly equal to an excess intake of 3500 calories, meaning that 122,500 calories of fat were gained over the 183 day period.

    122,500 calories gained in fat / ~183 days = ~669 calories gained in fat per day. You are claiming a daily intake of only 400 calories from ramen. Clearly, your scenario violates the laws of physics.

    You are being needlessly inflammatory, and posting from a position of ignorance. Her calorie intake was documented EXACTLY as I stated. Over a period of six months, she gained roughly 35 pounds, while eating approximately 300 calories per day. Those are the facts. The fact that you do not like those facts does not change reality.

    I am a physicist, and what you are claiming is highly implausible to the point of being what we men of science term utter bullshit. Allow me to explain:
    1. In this house, we obey the laws of thermodynamics!
    2. Let's say she really is eating only 300 Calories a day (54,000 Cal in 6 months), and that she gained 35 pounds in six months. Normally, a pound of body fat contains about 3,500 Calories (pure fat is 9 Cal / g, but some of that pound is water). 35 lb X 3,500 Cal / lb = 122,500 Cal, which is 68,500 Calories more than she ate! (Never mind that a person typically burns somewhat over a thousand Calories a day at rest.)
    3. This leaves a few possibilities:
        a. The weight she gained was mostly water. Possible, but retaining water isn't true obesity.
        b. She has a freak mutation that allows her to perform photosynthesis.
        c. She has a freak mutation that has caused her body to grow a Stirling engine inside of her, and she was in thermal contact with hot and cold reservoirs with which the Stirling engine could exchange energy, thus allowing her to convert atmospheric CO2 and water into sugars, etc.
        d. Some of the most fundamental and firmly held laws of physics are wrong.
        e. You're wrong.

    Those are the facts. The fact that you do not like those facts does not change reality.
