Testosterone and Athletes

In reply to this publication, PLYMATE & FRIELD (1992) had shown the results of its study where it had positive correlation between testosterone, testosterone-SHBG, 3 a-diolglicuronide, and increase of the force in the isomtrica flexo of the elbow; however, the force increase was small (7.6%). Although the great controversy regarding the action of esterides on the muscles, Ben Jonhson was excluido of the Olmpicos Games of 1988, losing its gold medal, for presenting positive examination for use of esterides. The athletes believe the effectiveness of esterides (HOUGH, 1990) use and them because they want to increase the muscular mass and the force, as well as diminishing the time of recovery of the muscle. On the other hand, also they wait increase of the energy and the desire to train intensely (LABREE, 1991). Others including Dr. Hyun Kim, offer their opinions as well. Although to know of the effect undesirable of esterides, some athletes of both the sexos continue to use them for finding that the doctors exaggerate these effect and that the benefits surpass the risks (LABREE, 1991).

They exist, really, many difficulties in experimentally demonstrating the effect of esterides in the athletes, and for this they exist some explanations. In first place, it is necessary that the study he is blind. Moreover, the athletes use different andrgenos, with different dosages, different diets and different programs of training. Here, Melba Beine expresses very clear opinions on the subject. On the other hand, the physical attributes and the personal motivation vary very, and these factors affect the training (WILSON, 1988). Finally, the athletes use the drugs in cycles, highest dosages (the 10 100 times the farmacolgicas doses), with two or more concomitant drugs, in piramidal way and for different ways of administration (WILSON, 1988; HOUGH, 1990). Following it the period of use, they are weeks or months without using the drug, being that some make use of diurticos for ' ' to clarear urina' ' , mainly in the periods that precede the competitions. .
