Guest guest Posted September 7, 2005 Report Share Posted September 7, 2005 I assume he was asking hypothetically... you need many many anecdotes.... Of course that is how some trends are first perceived. I suspect we have lots of experience with exercise wrt to general health. Lance and well known athletes get lots of ink because of the apparent paradox of a "healthy" athlete getting sick. Lance surely educated himself and consulted with cancer experts. While I don't know how he was advised, he returned to a very high level of activity so he apparently didn't perceive a risk. If we don't die young (too late for me) the odds increase that we will be at risk for cancer. Cancer is not one simple disease but multiple variations on a nasty theme. I suspect (moderate) exercise may be protective against some, perhaps supportive to others. I just read a report that they believe downs syndrome may be protective against "some" cancers. Cancer is a rather complex thing. I would suggest making exercise choices without much consideration for increased or decreased risk of the big C.

Guest guest Posted September 7, 2005 Report Share Posted September 7, 2005 Not disagree, I notice my friends who were active are not here, and I'm left with a lotta fat slobs all younger than me. My only sib remaining is 81yo, exmarine, gymed and exercised for many years, now has venous stasis and CHF. My wife's laws and in-laws all are living but one who overdosed on back pain medication. The men were all in the WWII, and are all 10+ yrs older than us. The oldest is still obese at 88 and can lift Jack Lalanne easily. If they were smokers, they quit, but in the main they are withering if they're not gaining. I think if people are exercising it's because they can. To sum up all the articles "healthy people live longer". Not to be smart alecky, but that's what they tell me. At some point you can't do things like you used to and it's not because of what you ate or didn't eat. I walk 2 or 3 miles because I take enough NSAIDS to do so. Not a day passes I don't think of my good friend who died at 59yo of brain cancer and I wonder why he's dead and not all these fat slobs around me. Or another friend who ran 5 miles per day everyday before work (20 yrs at least) and died at 65yo - SCD. They were active and thought they were the epitome on health like a lot of other "athletes". A coworker was a high school football referee in the evenings, died younger than that of heart disease. Go to the doc and get a stress test, colonoscopy, mammogram, and whatever blood tests available and keep the records. Regardless what you do to live longer, it's in your hands not theirs. Regards.

Guest guest Posted September 7, 2005 Report Share Posted September 7, 2005 Keep in mind, too, that these are all anecdotal and " one mouse " experiments. My co-worker's mother lived to 100 and she smoked her whole life. He continues to point to this as evidence that smoking isn't bad for your health. Nothing -- including CR -- is 100% insurance that you will live a long time. It's best to hedge your bets and do everything you can to stay healthy.

Guest guest Posted September 7, 2005 Report Share Posted September 7, 2005 Keep in mind, too, that these are all anecdotal and " one mouse " experiments. My co-worker's mother lived to 100 and she smoked her whole life. He continues to point to this as evidence that smoking isn't bad for your health. Nothing -- including CR -- is 100% insurance that you will live a long time. It's best to hedge your bets and do everything you can to stay healthy.

Guest guest Posted September 7, 2005 Report Share Posted September 7, 2005 We should keep in mind that " exercise " as commonly used is a very generic term that means almost anything to anyone. Most that I see in the local health club have as much clue about the way to properly exercise as they have about proper nutrition. The vast majority do the wrong " exercises " , or spend all their allotted time doing exercises that have limited benefit. Or do the right exercises with insufficient intensity and duration to overcome the body's natural tendency to resist adaptation to the physical stresses. Research has shown that up to a threshold, and that threshold is moderately high, higher intensities over longer periods impart the greatest benefit. Also demonstrated is that exercise levels too short or too " light " , or the " wrong " exercise do not provide anything in the way of desired goals, ie significant adaptation. So while these stories of hapless individuals that " exercised " but still became sick are interesting they are also impossible to evaluate and judge. Who knows what they did, how they exercised or for how long etc. They carry no weight with me for these reasons. After all, we all know a few CRON'ers that didn't make it too, don't we, despite healthly lifestyle choices. I've said this before, the ambiguous meaning of " exercise " and the fact of threshold effects, we need to establish an " OE " (Optimum Exercise) standard of terminology and application. > Re: [ ] Re: Exercise and Heart DiseaseNot disagree, I notice my friends who were active are not here, and I'm left with a lotta fat slobs all younger than me.

Guest guest Posted September 7, 2005 Report Share Posted September 7, 2005 As a scientist, I can't ignore any data whether it's called anecdotal or not. There is little scientific evidence in the health field's articles. Personal experiences are hard to dismiss. Armstrong is cylcing because he survived and can cycle - that's all I can conclude. I hafta think if exercise was good for longevity, footballers, eg, would live forever. Without pushing anything, allow me to post a medical text. DeLee: DeLee and Drez's Orthopaedic Sports Medicine, 2nd ed., Section D Athletes and Sudden Cardiac Death S. Dunnick MD, FACC Pheidippides may have been one of the first athletes to suffer a sudden death event during an athletic endeavor. Hank Gathers, Reggie , Flo Hyman, and Maravich may be among the better-known athletes to have suffered such an event. Although it has been reported with less dramatic publicity, sudden death of athletes during high school physical education class or on the Little League baseball diamond is equally tragic. I discuss both screening and more detailed diagnostic tests that are used to try to detect the athlete who is at higher risk. I also discuss the use of the evaluation for approximating risk groups in terms of probabilities and possibilities rather than absolutes. Barry Maron published a schematic of the number of athletes who were screened for heart disease. Not all athletes with heart disease have heart disease that is capable of producing sudden cardiac death. Not all athletes with a heart problem capable of causing sudden death actually go on to experience sudden death. Therefore, a large total number of athletes must be screened to determine the percentage who have heart disease. Then, the percentage of athletes with heart disease that can lead to sudden death is evaluated. Finally, it is the smallest group that actually goes on to experience sudden death. These types of statistical approaches lead to conclusions that in the minds of the athlete, the family of the athlete, the coaching staff, and the school administration show a variable range. On one end of the spectrum is complete fear of competing in any setting or after any degree of evaluation, regardless of how extensive it may be. On the other end, minimal effort is made to screen the athlete because it is believed that the problem is too infrequent to support the economic commitment.{interesting -what?} If the combined prevalence of congenital heart conditions that could cause sudden cardiac death is approximately 0.3% of the general population, we must begin to look at the total number of athletes involved.[42] If there are approximately 5000 professional athletes, 500,000 college athletes, and 5,000,000 high school athletes, the total number of 5,505,000 is reached. At 0.3%, it appears that there are 16,515 athletes with the potential for sudden cardiac death. Not all athletes with the possibility of having a sudden death event, however, actually die in this way. [72] estimated the incidence of sudden cardiac death that occurred during jogging in Rhode Island. During the period of 1975 through 1980, the incidence rate was reported as 1 death per 15,240 joggers per year. In a New England Journal of Medicine article written by Siscovick,[68] sudden death during “vigorous exercise” was reported as 1 cardiac arrest per 20,000 exercises in Seattle per year. The annual incidence rates of sudden death among joggers in Dallas [25] and marathon runners in South Africa[54] are reportedly higher: 3 to 4 per 20,000 exercisers per year. Multiple studies[68] [72] [77] have suggested that the risk of sudden death is increased during times of greater exertion in any given 24-hour period. In Finland, [77] a 4.5-fold increased risk was noted in cross-country skiers; in Rhode Island,[72] a 7-fold increased risk was recorded among joggers; and in Seattle,[68] a 6-fold increased risk in athletes has been documented. These studies provide good and reproducible data that indicate that there appears to be an increased risk of sudden death during exercise. This increased risk of sudden death during exercise actually decreases as a given individual spends increased amounts of time exercising. Siscovick showed that men who exercise for less than 20 minutes per week had a 56-fold increase in sudden death during exercise. As exercise time per week increased, the sudden death rate fell, and at peak, this rate for men exercising longer than 20 minutes per day was reduced to a 5-fold increase. {I notice this is less than the increased risk from HRT which has been criticized.} Causes The causes of sudden cardiac death among athletes vary by age [46] ( Fig. 7D-1 ). Numbers, again, are not exact but estimates have been made. In the athlete who is older than 35 years of age, coronary artery disease remains the most frequent cause of sudden cardiac death. Other diseases are prevalent at variable rates, however, as is shown in the figure. Figure 7-D-1 Estimated prevalences of cardiovascular diseases responsible for sudden death are compared in young (=35 years old) and older (>35 years) trained athletes. Top, Causes of sudden cardiac death in young competitive athletes (median age, 17 years), based on systematic tracking of 158 athletes in the United States, primarily from 1985 to 1995. In an additional 2% of the series, no evidence of cardiovascular disease sufficient to explain death was evident at autopsy. “Possible HCM” denotes hearts with some morphologic features consistent with (but not diagnostic of) hypertrophic cardiomyopathy. (Adapted from Maron BJ, Shirani J, Paliac LC: Sudden death in young competitive athletes. Clinical, demographic, and pathological profiles. JAMA 276:199-204, 1996. Copyright 1996, American Medical Association.) Bottom, Causes of sudden cardiac death in older trained athletes. Data were assembled by collating findings from available published studies.

(From Maron BJ, Epstein SE, WC: Causes of sudden death in competitive athletes. J Am Coll Cardiol 7:204-214, 1986. Reprinted with permission from the American College of Cardiology.) Among athletes, 90% of sudden deaths appear to occur during exercise, predominantly during late afternoon and early evening hours. Notice the TONE of the article is that some have heart problems - not that exercise can cure, or not cure. The idea is to detect those at risk and limit their activites, I suppose. Our TONE should be which exercise will extend life or lower mortality, - not vague claims that larger lumens are good, eg.
