The ideal hematocrit for athletic performance is thought to be 55 (expressed in percent). pictures of steroid users Equine-anabolics. Levels above this can result in "sludging" of the blood, which reduces microcirculation. This is counterproductive to oxygen transport. Additionally, at high hematocrit levels one is at greater risk for deadly vascular events such as stroke, especially if he/she becomes dehydrated during competition (which increases hematocrit even further). pictures of steroid users Injection-steroids. In addition to increasing aerobic efficiency through greater oxygen transport in the blood, there is some evidence suggesting EPO may also have anabolic effects. EPO has been shown in rat studies to substantially increase weight gain and injury repair after surgery. Furthermore, EPO receptors are present on myoblasts (immature muscle cell progenitors) and may have a potential in muscle development and repair. pictures of steroid users Injection-steroids. Corticosteroids:Corticosteroids, also known as glucocorticoids, are derivatives of cortisol. These steroid hormones have strong pharmacological effects such as increased gluconeogenesis (liver production of glucose), inhibition of inflammation, increased lipolysis (release of stored fatty acids), catabolism of proteinaceous tissue (i. e. muscle), and psychological symptoms such as euphoria and mania. Now if you are a bodybuilder enthusiast familiar with muscle building science, you probably are wondering how derivatives of cortisol could possibly be considered ergogenic aids. After all, you were taught to believe that cortisol is the evil destroyer of muscle tissue that makes us weak and soft. I agree with this statement in the case of chronic elevation of cortisol levels, or excessive long term use of systemic corticosteroid drugs. The use of corticosteroid drugs for performance enhancement however is meant for short term usage, and this minimizes the negative catabolic effects. Corticosteroid use can be a godsend in sports where injuries are prevalent, such as football or soccer. Injections of corticosteroids into inflamed connective tissue allow players to compete in cases where they otherwise would be in too much pain to function effectively. This usage of corticosteroids to treat acute injury is often allowed by sporting organizations to a limited extent (topical and inhaled corticosteroids are allowed as well). Excessive usage of these compounds to cover up an injury is asking for trouble however, as many an ex- NFLer can attest to. 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.
