Mike http://www.stuff.co.nz/dominion-post...eting-with-son Bike race victim competing with son SHANE COWLISHAW Last updated 05:00 06/02/2012 A Wellington man who died of a heart attack during a mountainbike race was taking part in the event with his son. James Craig, 53, was in the early stages of the Port Nicholson Poneke/ College Sport Wellington Mountain Bike Championships at the Wainuiomata Mountain Bike Park when he stopped after feeling dizzy, then collapsed. Another competitor stopped and attempted to resuscitate Mr Craig, but was unsuccessful. Race organiser Mark Renall said Mr Craig's teenage son, Oliver, was competing in the junior section. "I didn't know what he [Oliver] looked like ... it was terrible but I found him and just told him, 'I've got terrible news, you're father's died."' It had been known that Mr Craig had a heart condition but it was terrible he had died while exercising, Mr Renall said. "Most of the time mountain biking keeps you fit, but there's always that one in a 1000 chance." Family friend Ian Paintin said Mr Craig, who worked in kitchen joinery and lived in Wellington, had suffered a heart attack about 10 years ago but since then had taken his second chance and improved his health through exercise. With two young children and a wife, he realised he would not get far in his unfit state and embraced mountain biking. "Jim was a guy who was really trying to get the best out of life ...

Walking provides better exercise with far less danger -- something that mountain bikers keep trying to sweep under the rug. Pure speculation regarding a cardiac event. That is truly laughable. The entire medical profession disagrees with you as it relates to the increased likelihood of a cardiac event. See some of the exerts below. It is rather technical and likely too much for your tiny brain, but in plain English, what it concludes is that individuals that have heart conditions are more susceptible to to cardiac incidents when engaging in strenuous exercises - the type of exercise is not particularly germane for this analysis (are you at risk of a heart attack or not), simply does it elevate heart rate and stress the heart - they use jogging as the standard to determine the minimum amount of work load. It also concludes that healthy individuals with no genetic predisposition to heart disease or evidence of heart disease, reduce their low risk even lower by regular exercise that stresses the heart. They also conclude that those individuals that have some risk or are in poor shape, to only undertake activity under the supervision of their doctor, and by doing so even they will eventually reduce their risk of a cardiac event. So healthy individuals (such as myself - 58 years old, no family history of heart disease, 172 lbs, 6'3" 9.5 to 10% body fat, engage in 9 to 14 hrs of aerobic activity per week including speed skating, cycling, running, hiking and dryland training, plus 4 to 6 hrs of strength training and stretching) who continue to engage in activities that put a load on the heart (I regular push my HR between 170 to 180 for a few minutes at a time each week and easily maintain 150-155 on 30 to 60 minute climbs) are extremely unlikely to suffer a cardiac event while exercising. Individuals of poor fitness and/or history of heart disease put themselves at increased risk, unless they cautiously approach a regular exercise program set up by their doctor. Ask Jim Fixx the runner who is best know for writing The Complete Book of Running, who died of a heart attack while running - he had a previous diagnosed heart condition and he mistakenly thought running would cure it. Healthy runners, cyclist (road and mt), skaters, cross country skiers, etc. maintain their risk of a heart event as very low if they continue their activity. AHA Scientific Statement Exercise and Acute Cardiovascular Events Placing the Risks Into Perspective: A Scientific Statement From the American Heart Association Council on Nutrition, Physical Activity, and Metabolism and the Council on Clinical Cardiology In Collaboration With the American College of Sports Medicine; Paul D. Thompson, MD, FAHA, Co-Chair; Barry A. Franklin, PhD, FAHA, Co-Chair; Gary J. Balady, MD, FAHA; Steven N. Blair, PED, FAHA; Domenico Corrado, MD, PhD; N.A. Mark Estes III, MD, FAHA; Janet E. Fulton, PhD; Neil F. Gordon, MD, PhD, MPH; William L. Haskell, PhD, FAHA; Mark S. Link, MD; Barry J. Maron, MD; Murray A. Mittleman, MD, FAHA; Antonio Pelliccia, MD; Nanette K. Wenger, MD, FAHA; Stefan N. Willich, MD, FAHA; Fernando Costa, MD, FAHA a few exerts: High-Risk Activities Few systematic studies have identified high-risk activities, again because of the rarity of exercise-related cardiovascular events. In general, the risk of any vigorous physical activity is an interaction of the exercise per se and the individual’s physical fitness because identical physical tasks evoke lower cardiac demands in physically fit subjects than in unfit persons. Snow shoveling has repeatedly been associated with increased cardiovascular events,44,45 probably because it can elicit higher rate-pressure products than does treadmill exercise testing,46 because it is often performed out of necessity by unfit individuals, and because some cardiac patients develop angina at lower rate-pressure products, suggesting a coronary vasoconstrictor response, during exercise in cold temperatures.47 Strategies to Reduce Exercise-Related Cardiovascular Events No strategies have been adequately studied to evaluate their ability to reduce exercise-related acute cardiovascular events. Physicians should not overestimate the risks of exercise because the benefits of habitual physical activity substantially outweigh the risks. From observational studies,4 it appears that one of the most important defenses against exercise-related cardiovascular events in adults is to maintain physical fitness via regular physical activity because a disproportionate number of exercise events occur in the least physically active subjects performing unaccustomed vigorous physical activity.5,6,32 Several strategies to reduce events appear prudent although unproven. These include the following: preparticipation screening, excluding high-risk patients from some activities, reporting and evaluating prodromal symptoms, preparing fitness personnel and facilities for cardiovascular emergencies, and recommending prudent exercise programs. Each of these is discussed below. Preparticipation Screening Young Athletes The American Heart Association (AHA) recommends cardiovascular screening for high school and college athletes before athletic participation and at 2- to 4-year intervals.48,49 The examination should include a personal and family history and a physical examination focused on detecting conditions associated with exercise- related events.48 The AHA does not recommend routine, additional noninvasive testing such as a routine ECG. The omission of routine noninvasive testing is controversial because the Study Group on Sports Cardiology of the European Society of Cardiology has recommended that routine ECGs be obtained on all athletes as part of a preparticipation evaluation.50 The European recommendation is based largely on an observational study performed in the Veneto region of Italy.51 Italy has mandated the preparticipation screening of athletes, including an ECG, since 1982. The annual incidence of sudden death among athletes 12 to 35 years of age decreased 89% with screening, from 3.6 deaths to 0.4 deaths per 100 000 athletes. There was no change in deaths among nonathletes, which suggests that screening mediated the decrease. These results provide the best evidence to date in support of the preparticipation screening of athletes but have several limitations.52 The study did not directly compare the screening and nonscreening of athletes but was a population-based, observational study. Other changes in the management of the athletes could have contributed to the improvement. In addition, the study did not directly compare screening performed with and without an ECG. Finally, there could be small differences in the screened and comparison populations because the athletes were screened at the Padua Center for Sports Medicine, whereas the comparison population consisted of subjects from the larger Veneto region. Healthy Adults Although no data from controlled trials are available to guide the use of exercise testing in asymptomatic adults without known or suspected CAD before beginning an exercise training program, the writing groups from the American College of Cardiology (ACC)/AHA Guidelines on Exercise Testing53 and the American College of Sports Medicine (ACSM)54 have addressed this important issue by consensus. Although each group provides slightly different specific recommendations (see Table 4), the main theme of these recommendations is unified and clear: Individuals who appear to be at greater risk of having underlying CAD should be considered for exercise testing before beginning a vigorous (≥60% V̇o2 reserve) exercise training program (where V̇o2 reserve=percent intensity×[V̇o2 peak−V̇o2 rest]+V̇o2 rest). This is particularly evident in that both groups recommend exercise testing before exercise training for patients with diabetes mellitus. In contrast, the US Preventive Services Task Force (USPSTF) states that insufficient evidence exists to determine the benefits and harm of exercise stress testing before exercise programs.55 View this table: In this window In a new window TABLE 4. ACC/AHA, ACSM, and USPSTF Recommendations for Exercise Testing Before Exercise Training A major limitation of exercise testing is that “positive” exercise test results require the presence of a flow-limiting coronary lesion, whereas most acute cardiac events in previously asymptomatic subjects are due to vulnerable plaque disruption. Consequently, an exercise stress test with or without imaging can be normal despite the presence of coronary plaque that may rupture. This requires that health professionals evaluate the entire atherosclerotic risk profile in patients when advising on the feasibility of a vigorous exercise program. Recommending Prudent Exercise Programs Ostensibly healthy adults without known cardiac disease should be encouraged to develop gradually progressive exercise regimens. Because the least fit individuals are at greatest risk for exercise-related events, gradually progressive programs should theoretically increase fitness and reduce acute CAD events without excessive risk. Patients with known cardiac disease also should be counseled to include at least 5 minutes each of warm-up and cool-down in their exercise training sessions to reduce the likelihood of inducing cardiac ischemia with sudden, intense physical effort62,63 and to avoid the decrease in central blood volume that can occur with the abrupt cessation of physical activity. Patients with cardiovascular disease who are interested in participating in competitive sports should be evaluated and advised in accordance with the 36th Bethesda Conference guidelines.56 Physically inactive individuals and patients with known cardiovascular disease should avoid strenuous, unaccustomed exercise in both excessively cold and hot environmental conditions. Vigorous exercise in the cold such as snow shoveling has repeatedly been associated with acute cardiovascular events,44,45,64 and hot, humid environments require an increased heart rate response to handle the increased thermal load.65 Increased altitude reduces oxygen availability and augments the cardiorespiratory and hemodynamic responses to a given submaximal work rate, thereby increasing cardiac demands. Individuals exercising at altitudes of 1500 m should limit the intensity of their exercise until acclimatized.54,66 The long and short of is, if you are healthy continue to exercise (and yes mt biking is no more or less strenuous from a heart perceptive then triathlons, road cycling, speed skating, cross country skiing, inline skating, tennis, soccer, basketball, swimming running, etc.), however, if you have a heart condition, then work with your doctor and maybe you may need to stay away from the more strenuous sports. So in conclusion, mt biking does not put people at greater risk (or lesser) of a cardiac event then the myriad of other sports that are equally strenuous. That is not speculation and is presently well accepted in the medical profession. Enjoy, Rick |

Bike race victim competing with son SHANE COWLISHAW Last updated 05:00 06/02/2012 A Wellington man who died of a heart attack during a mountainbike race was taking part in the event with his son. James Craig, 53, was in the early stages of the Port Nicholson Poneke/ College Sport Wellington Mountain Bike Championships at the Wainuiomata Mountain Bike Park when he stopped after feeling dizzy, then collapsed. Another competitor stopped and attempted to resuscitate Mr Craig, but was unsuccessful. Race organiser Mark Renall said Mr Craig's teenage son, Oliver, was competing in the junior section. "I didn't know what he [Oliver] looked like ... it was terrible but I found him and just told him, 'I've got terrible news, you're father's died."' It had been known that Mr Craig had a heart condition but it was terrible he had died while exercising, Mr Renall said. "Most of the time mountain biking keeps you fit, but there's always that one in a 1000 chance." Family friend Ian Paintin said Mr Craig, who worked in kitchen joinery and lived in Wellington, had suffered a heart attack about 10 years ago but since then had taken his second chance and improved his health through exercise. With two young children and a wife, he realised he would not get far in his unfit state and embraced mountain biking. "Jim was a guy who was really trying to get the best out of life ....

Not too many hikers ram their heads into trees, break bones,or turn themselves into paraplegics and quadriplegics, as mountain bikers do.... DUH! Mike your reading and writing comprehension is poor and I must say, disingenuous. I summarize this discussion: You posted an article regarding a gentlemen who had a previous heart condition and died of a heart attack while mt biking - he did not injure himself or die due to crashing. - your post was and I quote "Evolution in Action!" Now as this gentlemen died from a heart attack and did not die from crashing, I noted that the the strenuous nature of mt biking puts this gentlemen (or others like him) at no more risk then any other sport that also puts similar loads on the heart. I indicated (and I am supported by the medical literature) that sports like running, road cycling, speed skating, inline skating, cross country skiing, snowshoeing, swimming, basketball, soccer, tennis, etc. also result in increased workload to the heart and individuals with pre-existing conditions would want to take on these activities under the supervision of their doctor. Those of us who do not have a family history of heart disease, no evidence of heart disease and are relatively fit, will find that our risk of suffering a cardiac incident is remarkably low and therefore regardless of what of the aforementioned activities we engage in (including mt. biking) we are not expected to suffer a heart attack, and need not modify our activity/training to anticipate one. I reiterate, your original post (i.e., the article you cited) and my subsequent response focused on a single issue - comparing cardiac events amongst the various strenuous sports. Healthy adults are at extremely low risk of a cardiac event during all strenuous sports including mt. biking. This was simply regarding heart health and sports - if you have other issues, it was not a part of these original posts and your attempt to shift the discussion is because you realized you were simply wrong to make this a heart issue. |

Why are you posting the whole damn mess just to make your non-point? Don't you know how to edit a post? We are comparing mountain biking to hiking only. You can hike all day long and never have to worry about your freaking heart. In fact, taking a long walk is good for your heart. One other seldom noted fact you seem to have missed. Very many mountain bikers are basically middle aged couch potatoes who only occasionally get off their dead asses. Mountain biking for such jackasses is indeed dangerous for their hearts as well as for other areas of their anatomies. Screw the dumb *******s all the way to hell and back!

Are your meds giving out that you cannot keep your attention span together long enough to read? No, Mike posted a article on a gentlemen who died while mt. biking implying strenuous exercise associated with mt. biking is bad, the medical profession disagrees with you and Mike. If you are a healthy adult, regular strenuous exercise is good for your heart health - even more than simply strolling through the forest, which in its own right is enjoyable for many different reasons. I made no value judgement as to mt. biking good or bad, simply your heart has no idea whether it is being "trained" or stressed while doing any number of back country activities such as trail running, cross country skiing, snow shoeing, and long distance power hiking. I assume you look on these extreme sports type with disdain as they are not walking through the forest with their walker. Most hikes I undertake are 10 plus miles and many push 20 miles usually at high elevation (the Sierra, I own a house at 6400 ft and go up from there) with extreme elevation gain. You may haul your over weight ass at a snails pace so your heart rate does not get above 75 bpm, but I and most of my hiking friends push ourselves. Maybe you hang out at the pub keeping your belly large, but I hang out with a largely uber fit crowd of hikers, runners (I have a couple of friends who are part of the ultra marathon crowd, 50 to 100 mile back country runs), cyclist (most road cyclist, but some mt. bikers), triatholoners, skaters who all crave (admitted addicted) to aerobic activities 4 to 6 times a week. I just got back from a 2 hr dryland training (for skating) where we did these 15 minute drills that you feel like you want to throw up afterwards - this will greatly improve our skating fitness and we thrive on the pain. So I guess you and Mike will now lobby to keep all of those crazed uber fit trail users off the trails now. Oh Minnesota, the great state where Santorium just won the Republican caucus. Tell you what you stay in Minnesota, you fit the nut cases there. Enjoy, Rick |
