Interesting health study
This was just linked to over at URC.
http://news.bbc.co.uk/1/hi/health/3991633.stm Air pollution caused by traffic and factories may cause heart disease, a US study suggests. I wonder how much more intense the effects would be in an endurance athlete due to moving that much larger a volume of bad air through their lungs regularly. Would the training benefits offset the damage done by the pollutants? Hopefully someone here has some thoughts on this. Bill C |

I also seem to remember that it tended to support moderate exercise even in polluted environments (with the caveat that one should preferably exercise early in the day, when IIRC ozone and nitrogen oxides and particulates would be somewhat lower in level). However, this would be one of those studies that mean less that it would seem, because how one calculates the real risk of pollution varies so much from individual to individual. To give an extreme example, giving a blanket endorsement of this kind to an asthmatic patient would be irresponsible in the extreme. It may also be that living close to factories could be associated with other risk factors, such as poverty, pre-existing pulmonary disease, etc. Steve -- Mark & Steven Bornfeld DDS http://www.dentaltwins.com Brooklyn, NY 718-258-5001 |

My allergies get much worse as my training volume goes up. Also, this makes me recall the "controversy" of the percentage of athletes relative to the greater population that use meds for asthma. Why is it so hard to beleive that there will be larger number of cases when this group clearly uses their lungs a lot more and at rates that pushes some of these organs to their limits?

Bill C And how much training is done near traffic (higer concentration of pollutants)? On the up side I read somewhere that riding along side traffic can increase you avg speed. -p |

I don't disagree, but athletes are more likely to seek asthma meds than your average person who doesn't feel the effects of asthma as much, or isn't bothered by the effects as much. -WG |

Bill C I'll do some digging and see if I can locate the article I read this past summer in our local paper. It talked specifically about high ozone levels and athletic activity. It concluded that it was potentially quite harmful (long term) to exercise during an ozone alert. The article was quite specific about the kinds of damage that would be done. It was quite a compelling case and I steered clear of some late afternoon club rides and training sessions during the hot and hazy days of July and August. Though I live in a remote, rural area, I'm about 2 1/2 hours down the prevailing wind from Atlanta. Usually you can only smell cows around here. Sometimes you can smell Atlanta. Bob C. |
