Drug Scandal NOT Taxation
Originally posted by Drs Branch Chain Amino Acid.
The human body needs 20 amino acids. It can make 12 of them. The other 8 it must get from other sources. This 8 includes the 3 BCAAs: leucine, isoleucine, and valine. They are hugely important to muscle, typically forming about one third of your muscle mass. Unless you're a competitive bodybuilder who needs the 0.1% advantage you might get from free form BCAA supplementation then forget about it. Serious Cycling has a snipper about BCAAs. "It has been known for a long time that BCAAs play a critical role in the turnover of lean body tissues (muscle) and are muscle sparing in a variety of muscle- wasting states." "Leucine appears to be the most important for preserving hard- earned muscle mass and intense excercise" "The main drawback of leucine is the fact that you must use large amounts to get a positive effect, making it both expensive and impractical. In many studies that showed benefits, doses were in fact given intravenously and were as high as 5 grams per hour.." HMB, a metabolite of leucine, taken 3g/day is said to be suitable for cyclists wishing to increase strength and power. What do you know about this HMB stuff DRS? hippy -- |

[...] Serious Cycling has a snipper about BCAAs. "It has been known for a long time that BCAAs play a critical role in the turnover of lean body tissues (muscle) and are muscle sparing in a variety of muscle- wasting states." Yes, the BCAAs are anti-catabolic as well as anabolic. Rather a nice combination if you want muscle growth. And when you look at the amino acid profiles of protein supplements you'll see the BCAAs constitute a significant proportion of the amino acids. [...] HMB, a metabolite of leucine, taken 3g/day is said to be suitable for cyclists wishing to increase strength and power. What do you know about this HMB stuff DRS? According to an AIS meta-analysis, HMB supplementation is of small benefit and then mainly to beginners [1]. Other such non-HMB supplement vendor analyses tend to agree [2]. Moreover, its anti-catabolic mechanism is still not understood. However, there is some evidence it has some medicinal value in combatting cancer or AIDS related wasting [3][4]. I personally don't believe any non-elite athlete need even consider free form amino acid supplementation. If your diet is already adequate in protein (defined as about twice the ridiculously low RDI) then you're already getting enough amino acids. Furthermore, contrary to popular belief in some circles, amino acids are absorbed more quickly when ingested in the form of high BV proteins than they are when taken in free form. Amino acids in hydrolyzed whey protein, for example, are absorbed more than twice as fast as those in free form. In short, HMB supplementation is a stupidly expensive waste of money for most people. [1] http://www.ais.org.au/nutrition/9hmb.pdf [2] eg, "It is claimed that HMB can increase lean muscle mass and exercise performance, but this is far from conclusively established." http://www.gettingwell.com/drug_info...bet_0138.shtml [3] The American Journal of Surgery Volume 183, Issue 4, April 2002, Pages 471-479 Reversal of cancer-related wasting using oral supplementation with a combination of -hydroxy--methylbutyrate, arginine, and glutamine Patricia Eubanks May M.D.a, b, , , Annabel Barber M.D.b, James T.

[...] Unless you're a competitive bodybuilder who needs the 0.1% advantage you might get from free form BCAA supplementation then forget about it. Further to this, the article "Branched Chain Amino Acids" by David Tolson in full is highly detailed and may be more than most people want to know, but if you're interested in this stuff then check it out. Here is part of its conclusion: "All in all, it would appear that the positive effects of BCAA's on protein synthesis can be achieved by a high protein diet and use of a fast-acting protein prior to and after exercise, and that most of the other possible benefits on exercise performance could be achieved equally as effectively by ingesting simple carbohydrates prior to exercise. If caloric intake must be limited at all costs, or if protein intake is inadequate, BCAA's may be useful in this respect. Also, a unique benefit of reduced CNS fatigue by decreasing tryptophan buildup cannot yet be discounted. Given the other properties of BCAA's described below, the usefulness of BCAA supplements can further be questioned." http://www.1fast400.com/?ingredients_id=59 -- A: Top-posters.

news A close friend's daughter had Vit shots to assist with illness that was complicated by severe anaemia. True, she was one unwell puppy, but the shots helped boost her immunity and shortened recoverey time. (altho the kid was none too happy about the shots, I can tell ya!). Oops silly me I thought it was obvious from the context we were talking about racing cyclists, not ill people. |

What's the go with Mark French naming Graeme
Brown as 'one of the five' to use in the SA AIS when Brownie wasn't even in Adelaide at the time?! How does that work? Is Frenchy on drugs or something? Oh wait... hippy |

Oh wait... hippy Drug needs for a sprinter/kilo rider are different to an endurance rider. One wonders why Brown was included in the five if the allegation included PED's relating to equinine growth hormones. However, growth hormones play a role in recovery Vitamins are injected (usually in the buttocks) as there is a guarantee, so to speak, the vitamin will be absorbed. Taken orally the vitamins have to navigate the digestion system where there is a loss of vitamin plus a time delay to absorption of the remainder. Injections provide near instant response plus a more accurate dose to measure to the deficiency, provided a blood sample has been analysed. -- |

Funnily enough, I read the following paragraph, from Lance's second book "Every Second Counts" this morning on the train: "The TdF is not a natural event. We ride more than 100 miles a day for three straight weeks, through incredible and changing conditions. Some cars wouldn't hold up under that physical stress, much less a human body. We needed help, in the form of IVs of vitamins, minerals and phosphates. You simply can't eat or drink enough to make up for that kind of depletion, to replace all the things you expend. Those IVs and syringes were health essentials." He is referring to when someone shot footage of USPS team doctors disposing of medical rubbish in a roadside garbage bin. hippy |

There's an interesting rebuttal to the "unnatural" argument in a letter to cyclingnews.com from someone at the School of Exercise and Sport Science at Sydney University http://www.cyclingnews.com/letters/?id=2004/jul02letters. In part: "The current dogma in organised sport today is to engage in 'super' nutrition and hydration in order to be successful. This has been highlighted in recent events at Australia's premier sporting institute, the AIS, where it seems young cyclists regularly inject themselves with mega-doses of vitamins to cope with the rigors of training and as Dr Ferrari puts it, the effects of 'a whole series of lesions to cells and function of these apparatuses'. The step to illegal drugs is then a small one (e.g. equine growth hormones found at the AIS). "To say that cycling is a stranger to the evolutionary process is wrong and dangerous in respect to young naive cyclists presuming that I.V. drips and injecting mega-doses of vitamins is the norm even in the absence of scientific evidence. In reality human beings have evolved to cope with all manner of physical stresses, including riding the Tour de France." -- Shane Stanley |
