Revolta anticomunista de la Brasov, din 15 Noiembrie 1987, a fost evenimentul politic major care a anuntat prabusirea iminenta a comunismului în România. Revolta s-a declansat la Întreprinderea de Autocamioane Brasov, printr-o greva începuta în data de 14 noiembrie, noaptea, la schimbul III si continuata a doua zi dimineata cu un mars, pâna în centrul orasului, în fata Comitetului Judetean al Partidului Comunist Român. Refuzul autoritatilor comuniste de a dialoga cu demonstrantii a provocat luarea cu asalt a sediului comunist de catre multimea adunata. Portretul dictatorului Ceausescu a fost doborât de pe frontispiciul cladirii si incendiat. A urmat interventia brutala a trupelor speciale de securitate, arestarile, torturile etc. Dupa ce initial se anuntase pedeapsa capitala pentru muncitorii arestati, sub presiunea opiniei publice mondiale, comunistii au revenit asupra hotarârii lor, deportând, în urma unui proces înscenat, un numar de 61 de muncitori si schimbând locurile de munca ale altor 27 de persoane dintre cele peste 300 arestate si anchetate în sediile Militiei si Securitatii din Brasov si Bucuresti.

Dupa evenimentele din decembrie 1989, majoritatea celor deportati s-au reîntors în Brasov. Vasile Vieru, unul dintre cei 61 de muncitori deportati, decedase însa la Bârlad, în septembrie 1988, la mai putin de un an de la ancheta, în urma maltratarilor la care a fost supus la Inspectoratul General al Militiei din Bucuresti.

In memoria acestor evenimente Asociatia 15 Noiembrie 1987 organizeaza evenimentul sportiv 'Crosul 15 Noiembrie 1987'. In acest an crosul va fi organizat in data de 12.11.2011. Mai multe informatii gasesti pe:

Nonalcoholic Beer Aids Marathon Recovery


Fred R. Conrad/The New York Times

A new study reports that beer is an excellent recovery beverage for marathon runners. But you may not want to start a raucous celebration just yet. The beer was effective only if it was nonalcoholic.

Running a marathon is, of course, punishing to the body, causing muscle soreness and inflammation. Grueling exercise can also weaken the immune system, making athletes susceptible to colds and other ills in the weeks after the event. Some athletes, particularly in Europe, long had downed nonalcoholic beer during hard training, claiming that it helped them to recover, but no science existed to support the practice.

To study the matter, researchers at the Technical University of Munich approached healthy male runners, most in their early 40s, who were training for the Munich Marathon, and asked if they would — in the name of science — be willing to drink a considerable amount of beer. Two hundred seventy-seven men agreed, even when told that the beverage would be nonalcoholic. Only half of the group received the alcohol-free beer, however; the other half got a similarly flavored placebo. No one knew who was drinking what.

All of the runners downed a liter to a liter and a half — about two to three pints — of their assigned beverage every day, beginning three weeks before the race and continuing for two weeks afterward. The scientists, meanwhile, collected blood samples from the men several weeks before the race, as well as immediately before to the start, at the finish line and on select days afterward. (These were an exceptionally obliging group of racers, it seems.) They monitored levels of various markers of inflammation in the men’s blood, to see whether beer helped to blunt some of the immediate damage from running.

For the next two weeks, the men continued to dutifully swallow their nonalcoholic beer or other brew. They also reported any symptoms of colds or other upper respiratory ailments that developed during that time.

The men drinking the nonalcoholic beer reported far fewer illnesses than the runners swallowing the placebo beverage. “Incidence of upper respiratory tract infections was 3.25-fold lower” in the nonalcoholic beer drinkers, the scientists reported, in the journal Medicine & Science in Sports & Exercise. They also showed significantly less evidence of inflammation, as measured by various markers in their blood, and lower counts of white blood cells than the placebo group, an indication of overall better immune system health.

These effects matter, said Dr. Johannes Scherr, lead author of the study, because if a marathon runner’s body is less sore and inflamed after a race, and he doesn’t develop the sniffles, he can recover and return to training more quickly than he otherwise might have been able to. “It can be speculated that the training frequency could be higher (with shorter breaks after vigorous training sessions)” in those drinking beer, he wrote in an e-mail response.

Just how nonalcoholic beer eases the ravages of strenuous marathon training and racing is still being investigated. But, said Dr. Scherr, it almost certainly involves the beverage’s rich bouquet of polyphenols, chemical substances found in many plants that, among other things, “suppress viral replication” and “influence the innate immune system positively,” all beneficial for fighting off a cold.

Alcoholic beer happens to be drenched in polyphenols, too — “even more than nonalcoholic beer,” Dr. Scherr said — but has the signal disadvantage of being alcoholic. “We do not know whether the side effects of alcoholic beer would cancel out the positive effects caused by the polyphenols,” he wrote. “Furthermore, it is not possible to drink one to one and a half liters of alcoholic beer per day, especially not during strenuous training.” We all knew that, right?

Of course, other substances containing polyphenols have shown early promise, and then underperformed in follow-up studies. Quercetin, for instance, a polyphenol derived principally from apple skins, was widely touted by endurance athletes several years ago after studies found that large doses allowed untrained lab mice to run for far longer than untreated animals. But the supplement has largely failed to show benefits in human athletes. An analysis of 10 human studies of the supplement presented at the American College of Sports Medicine annual meeting in June concluded that quercetin supplementation “is very unlikely to provide an endurance performance advantage.”

But the beer experiment did not begin by looking at mice. It began with human marathoners completing a punishing, unsimulated race, and showed demonstrable benefits, in terms of minimizing postrace damage.

All of which is good news as the fall marathon season approaches. Asked if he would recommend that serious marathon runners add nonalcoholic beer to their diets, Dr. Scherr said, “When I look at the results of our study, I would have to answer ‘Yes.’”

It’s possible to get large amounts of polyphenols from other foods, he added, like those training-table staples chokeberries and mangosteens, as well as pomegranates and grapes. “But with these foods you do not consume the minerals, fluid and carbohydrates,” he said, “so nonalcoholic beer seems to be optimal” for everything, perhaps, apart from your well-deserved celebratory carouse after the race. For that, at least, the beer can be full-potency.

Maresc vitaminele riscul decesului ?

Some antioxidant supplements may increase the risk of death

Many people take vitamin supplements in the belief that this will improve their health and wellbeing. However, some of those supplements may actually prove to be dangerous. An analysis of previous studies suggests that the antioxidant supplements beta carotene, vitamin A and vitamin E may increase the risk of death.

Articolul care sta la baza acestui interviu: Surviving Antioxidant Supplements

Norman Swan: Welcome to the program. This morning on the Health Report the importance of fractured bones and how in some circumstances they can be foretelling your future.

How an antioxidant supplement might help people with HIV AIDS and how other antioxidants may be linked to a higher risk of death in the general public and people with certain conditions.

A study published a few days ago in the Journal of the American Medical Association has produced angry responses from the vitamin industry. A group of Danish researchers analysed the available evidence on antioxidant supplements and found that several of them are associated with an increased chance of dying prematurely.

One of the team is Dr Christian Gluud who's head of the Copenhagen Trial Unit at Copenhagen University. The thing to note here is that Dr Gluud's study isn't the first to make such a finding.

Christian Gluud: No there's been several systematic reviews and meta analyses showing that you either do not obtain any benefits from antioxidant supplements or that you may bring on hazzards by taking them. And actually we did one of the first systematic reviews on the topic back in 2004 where we looked at all the antioxidants that we had looked at now, that's beta-carotene, vitamin A, vitamin E, vitamin C and selenium and at that time we focused on all the files that addressed the question can these supplements reduce the risk of cancers in the gastro intestinal tract.

What we found at that time was that there wasn't any benefit on cancer development in the gastro intestinal tract, and the liver, and the pancreas however we saw a trend towards an increased all cause mortality. And when we focused on the trials with good methodology, that is trials with low risk of bias, we saw to our surprise a significant increase in all cause mortality.

Norman Swan: And we should just explain some of the techniques by which you analyse these trials is that you surveyed the medical literature, scientific literature, you find the trials then you cast an eye over them, or more than an eye over them in terms of their quality, how big they were, how well the statistics were, how well people were randomised. All those sorts of technical things and then you either throw out trials that are just rubbish or you can also do what you've just suggested which is that there are some trials that might be more accurate because of the way they were designed. And what you're saying here is when you lumped them all together when you were looking for gastro intestinal cancer there was a little bit of a suggestion of mortality but when you got the better quality trials which were less likely to be in error, they panned out to have a higher mortality rate.

Christian Gluud: Exactly.

Norman Swan: So this time you've looked at what - everything, any use of antioxidants?

Christian Gluud: Yeah, what we were accused of last time was maybe hitting what we call a random error because we hadn't looked at all the trials that were available. So we decided to go forth with looking at all trials that included either healthy participants or people having had a diagnosis of some sort of disease but weren't acutely ill any longer.

Norman Swan: This might would be things like - there was a trial for example of beta carotene in smokers to prevent lung cancer and there have been all sorts of trials with dementia and heart disease and things like that.

Christian Gluud: Yeah, a lot of trials. I think we have included around ten or eleven trials and people having some sort of gastro intestinal disease also that number with people having had cardiovascular disease, and six trials with neurological diseases and coupled with occular diseases and then a number of smaller groups of trials or unspecified diseases. Those were grouped under secondary prevention while the large group of participants came from what we call healthy participants, people walking along the street.

Norman Swan: And that's primary prevention where you're giving them vitamins in the hope that you'll prevent disease in the first place and secondly prevention is you've already got it and you're stopping it from getting worse.

Christian Gluud: Exactly.

Norman Swan: What did you find? First of all you've got about 70 trials didn't you with about 230,000 people

Christian Gluud: Yes, it's one of the more intensely researched topics in the world and there has been an enormous interest in this topic during the last 17 to 20 years and all the trials have been reasonably published and I must stress from the very beginning we have only been able to address what was in the published literature. But we have written direct mails to all the authors and asked them for further information and in the 68 trials that we were able to include we saw where we looked at all the antioxidant supplements together no significant harm but also no significant benefit. And then when we redid the subdivision of the trials into a group of trials with low risk of bias that is the highest methodological standard that you are able to find in the world, we see in that group that some of the supplements do harm. We see an increased mortality from beta carotene that's around 7%, from vitamin A that's around 16% increased mortality, and from vitamin E that's around 4% increased mortality. And all those figures are due to the huge number of participants - significant.

Norman Swan: So vitamin A was the top of the league?

Christian Gluud: Vitamin A seemed to cause the greatest harm.

Norman Swan: Now beta carotene was shown to increase lung cancer in smokers, if you eliminate that particular trial from the beta carotene story does it still increase mortality?

Christian Gluud: We haven't done specifically that sub-group analysis but that trial is involved. But as far as I remember this trial is not that big that it will change our results because when you reach the number of participants that you have here, you have very, very stable estimates and to take out one or two trials does not really rock the boat.

Norman Swan: And vitamin C and selenium got a clean bill of health?

Christian Gluud: No, I wouldn't say that. It is too early to say that. If you look at vitamin C the verdict is still hanging and I know that there are several trials in the world going on right now and I think we've got to see what they come up with before we have a final estimate on benefits and harm.

Norman Swan: And selenium?

Christian Gluud: Selenium - there we saw if you included all the trials, also the trials that may contain bias, there we saw a significant benefit from it. But it was very close to not being significant and if we excluded the trials that are likely biased we don't see any significant effect any more. But yet again the trials that are conducted with selenium at the moment I think they should continue because we also need more evidence there.

Norman Swan: And is it all causes of death or do some causes dominate?

Christian Gluud: We haven't seen a new way of dying. It's not that these anti oxidant supplements give you a new cause of death so to speak. The most likely is that we see an acceleration of atherosclerotic vascular diseases and an acceleration of cancer and that could be the mechanism.

Norman Swan: So your working hypothesis is that you're sitting in your motor vehicle of fate, heading for your fate, and antioxidants just put the foot on the gas a bit more than would otherwise be?

Christian Gluud: Yep.

Norman Swan: What's the take away message then - throw out the pills?

Christian Gluud: I would go back to the store where I bought them and ask them to destroy them because you shouldn't pollute the oceans with it, you do have to take care they are not non-toxic. That's one take home message but I think we should try and get something positive out of this and one of the positive things I think we could get out of it is first of all to request that anything being sold to consumers should be well tested before we start the marketing campaigns. And that also goes for vitamins, I think we've been up too early with marketing that it was good to take these things and that creates the furore that we face right now because people say oh, it can't be, we have heard for 10/20 years that it works well. It doesn't seem to work well according to our research.

Secondly I think it's mandatory that all governments now really get out of their chairs and do require that we get a registration of trials so that we are able to find it. It has taken us years to reach this conclusion and it's been very, very difficult to identify all the trials and to find out which publications of trials were actually on the same group of patients. These 68 trials were published in no less than 385 different publications.

Norman Swan: So some academics are getting their maximum mileage out of them.

Christian Gluud: There are some marketing people also within the academic circle for sure.

Norman Swan: And when you're talking about clinical trial registration here you're talking about this move towards trials having to be registered when they're started so you can actually track them much more accurately?

Christian Gluud: Exactly.

Norman Swan: I've already had my first email from a large manufacturer in Australia of vitamin supplements, what sort of criticism have you had in Europe?

Christian Gluud: Yesterday I had a number of calls from the United States and there the message I got was the very same that the manufacturers weren't happy and I do understand that they are annoyed by our results. The only thing I can say to people criticising this - please come up with better evidence. If they can mount a systematic review following the same strict way of doing it as we have tried to, I'll be happy to see other results of course. But I fear they will have difficulties doing that.

Norman Swan: Dr Christian Gluud who's Head of the Copenhagen Trial Unit at Copenhagen University in Denmark. And you're listening to the Health Report here on ABC Radio National.

The Human Body Is Built for Distance - Does running a marathon push the body further than it is meant to go?


Arnulfo Quimare, a Tarahumara Indian who is a champion distance runner, laces up his sandals for a 50-mile race on canyon trails. 

Published: October 26, 2009
The conventional wisdom is that distance running leads to debilitating wear and tear, especially on the joints. But that hasn’t stopped runners from flocking to starting lines in record numbers.

Last year in the United States, 425,000 marathoners crossed the finish line, an increase of 20 percent from the beginning of the decade, Running USA says. Next week about 40,000 people will take part in the New York City Marathon. Injury rates have also climbed, with some studies reporting that 90 percent of those who train for the 26.2-mile race sustain injuries in the process.

But now a best-selling book has reframed the debate about the wisdom of distance running. In “Born to Run” (Knopf), Christopher McDougall, an avid runner who had been vexed by injuries, explores the world of the Tarahumara Indians of Mexico, a tribe known for running extraordinary distances in nothing but thin-soled sandals.

Mr. McDougall makes the case that running isn’t inherently risky. Instead, he argues that the commercialization of urban marathons encourages overzealous training, while the promotion of high-tech shoes has led to poor running form and a rash of injuries.

“The sense of distance running being crazy is something new to late-20th-century America,” Mr. McDougall told me. “It’s only recently that running has become associated with pain and injury.”

The scientific evidence supports the notion that humans evolved to be runners. In a 2007 paper in the journal Sports Medicine, Daniel E. Lieberman, a Harvard evolutionary biologist, and Dennis M. Bramble, a biologist at the University of Utah, wrote that several characteristics unique to humans suggested endurance running played an important role in our evolution.

Most mammals can sprint faster than humans — having four legs gives them the advantage. But when it comes to long distances, humans can outrun almost any animal. Because we cool by sweating rather than panting, we can stay cool at speeds and distances that would overheat other animals. On a hot day, the two scientists wrote, a human could even outrun a horse in a 26.2-mile marathon.

Why would evolution favor the distance runner? The prevailing theory is that endurance running allowed primitive humans to incorporate meat into their diet. They may have watched the sky for scavenging birds and then run long distances to reach a fresh kill and steal the meat from whatever animal was there first.

Other research suggests that before the development of slingshots or bows, early hunters engaged in persistence hunting, chasing an animal for hours until it overheated, making it easy to kill at close range. A 2006 report in the journal Current Anthropology documents persistence hunting among modern hunter-gatherers, including the Bushmen in Africa.

“Ancient humans exploited the fact that humans are good runners in the heat,” Dr. Bramble said. “We have such a great cooling system” — many sweat glands, little body hair.

There is other evidence that evolution favored endurance running. A study in The Journal of Experimental Biology last February showed that the short toes of the human foot allowed for more efficient running, compared with longer-toed animals. Increasing toe length as little as 20 percent doubles the mechanical work of the foot. Even the fact that the big toe is straight, rather than to the side, suggests that our feet evolved for running.

“The big toe is lined up with the rest, not divergent, the way you see with apes and our closest nonrunning relatives,” Dr. Bramble said. “It’s the main push-off in running: the last thing to leave the ground is that big toe.”

Springlike ligaments and tendons in the feet and legs are crucial for running. (Our close relatives the chimpanzee and the ape don’t have them.) A narrow waist and a midsection that can turn allow us to swing our arms and prevent us from zigzagging on the trail. Humans also have a far more developed sense of balance, an advantage that keeps the head stable as we run. And most humans can store about 20 miles’ worth of glycogen in their muscles.

And the gluteus maximus, the largest muscle in the human body, is primarily engaged only during running. “Your butt is a running muscle; you barely use it when you walk,” Dr. Lieberman said. “There are so many features in our bodies from our heads to our toes that make us good at running.”

So if we’re born to run, why are runners so often injured? A combination of factors is likely to play a role, experts say. Exercise early in life can affect the development of tendons and muscles, but many people don’t start running until adulthood, so their bodies may not be as well developed for distance. Running on only artificial surfaces and in high-tech shoes can change the biomechanics of running, increasing the risks of injury.

What’s the solution? Slower, easier training over a long period would most likely help; so would brief walk breaks, which mimic the behavior of the persistence hunter. And running on a variety of surfaces and in simpler shoes with less cushioning can restore natural running form.

Mr. McDougall says that while researching his book, he corrected his form and stopped using thickly cushioned shoes. He has run without injury for three years.
