The compounds are very effective, and the edge it gives the user over the non-user is often profound. usa steroid prescriptions Steroid cycles. Even if a competitor has butterflies before the competition, the beta-blocker can effectively prevent the adrenaline induced nervousness from impeding performance. Beta Blockers are very specific for these "steady hands" sports, and are probably detrimental in other sports due to reduction of reaction time and strength. Examples of beta- blockers are Propanolol (Inderal (r)), and Atenolol (Tenormin (r)). usa steroid prescriptions How steroids work. ViagraAll right, no person that I know of is using Viagra as a performance enhancer (for athletics) yet. For a while though I have wondered whether it could have any usefulness however, since there is some indirect scientific evidence that suggests it might. Furthermore, I just recently found out that they have been using it in racing greyhounds in Ireland, where trainers call it "the best thing since sliced bread". usa steroid prescriptions History of anabolic steroids. Viagra works by increasing the effects of nitric oxide (NO), a substance that serves many key functions in biological processes throughout the body. One of the most well known and important functions of NO is the dilation of blood vessels. This allows greater blood flow to the muscles, which of course can be valuable to an athlete during competition. What is more interesting to me is the role of NO on muscles during resistance training. JE Anderson found that NO appears to be a vital signal in the activation of muscle satellite cells in response to damage. Satellite cell activation is the key first step in the repair and hypertrophy of muscle cells after heavy training. Viagra may therefore enhance the hypertrophy response to exercise, working at the most basic and primary level of the process. In addition to this, there is evidence that suggests that Viagra may work to amplify the "pump" response during training. The pump is thought to happen when contracting muscle fibers signal local vascular relaxation (increasing the blood flow to the working muscles). According to KS Lau and coworkers, NO generated by neuronal NO synthase in contracting skeletal muscle fibers may regulate vascular relaxation via a cGMP-mediated pathway. Since the mechanism of action for Viagra is amplification of the cGMP pathway, there is ample reason to believe that the drug may indeed affect the blood flow and pump to the muscle, and therefore indirectly aid in the hypertrophy response. Wrap upYou probably recognize now just how extensive the science of performance enhancement is. What I presented here is just a sample of some of the lesser known substances used to assist athletes. I did not even touch on the nutritional and natural products that athletes use. The pursuit of excellence goes on, and the pressures (financial, social) on athletes to win are just making the pursuit more and more desperate.
