Excessive usage of these compounds to cover up an injury is asking for trouble however, as many an ex- NFLer can attest to. steroid abuse photos Muscles teens. In contrast to the conditional permissive use of corticosteroids in acute injury treatment, the usage of corticosteroids to increase endurance, mask pain, and stimulate mental / CNS activity is strictly prohibited by sports organizations. Corticosteroids increase the performance of endurance athletes significantly, by enabling them to keep their blood glucose elevated for longer periods, and by masking the pain of the physical overload on joints and muscles. Specifically speaking, the gluconeogenic activity and lipolytic actions provide the athlete's working muscles with a rich blood supply of energy substrates for going that "extra mile". steroid abuse photos Steroid-synthesis. Additionally, the anti-inflammatory and analgesic activity covers up the discomfort of the massive physical overload. Furthermore, the corticosteroids can have a mild stimulant and euphoric effect on the athlete, charging him up for the event and keeping him or her focused throughout the performance of the grueling task. Beta BlockersBeta Blockers are a class of drugs that block beta-adrenergic receptors in the body from being stimulated by substances such as adrenaline (epinephrine), which is a key agent in the sympathetic portion of the autonomic (involuntary) nervous system. steroid abuse photos Teen-bodybuilding-gallery. Beta-blockers are used in conventional medicine to control hypertension, cardiac arrhythmia, angina pectoris, and migraine headaches. By blocking the action of the sympathetic nervous system, betablockers slow the heartbeat, lessen the force with which the heart muscle contracts, and reduce blood vessel contraction in the heart, brain, and throughout the body. Archery and shooting event athletes have used beta-blockers to steady their nerves, and to reduce pulse related vibrations in the arm by slowing of the heart rate. The compounds are very effective, and the edge it gives the user over the non-user is often profound. 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)). 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". 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).
