Since increases in muscle strength are proportional to increases in the cross-sectional diameter of the muscles being trained, the body must convert greater than normal amounts of amino acids available to it to increase size in athletes in training. When androgens became available in the 1930's they were used primarily to restore positive nitrogen balance in victims of starvation. Anabolic steroids, which were developed to avoid unwanted effects of androgens, were first given to weight lifters, but football players and weight throwers were soon using them. From 1965 to 1977, 25 clinical studies were published dealing with the administration of an anabolic-androgenic steroid to adult human males for evaluating changes in strength and, in 10 of these studies, in maximum oxygen consumption. In 12 of these studies, improvements were claimed from the use of these steroids; in the other 13 no improvements were observed. Other studies have shown that in healthy adult males these steroids reduce testosterone and gonadotrophin output, which reduces spermatogenesis. Alterations of normal liver function have been found in up to 80% of persons treated with C17-alkylated testosterone derivatives. Peliosis hepatitis, with liver failure and death, and fatal liver cancer have also been reported in adults so treated. Reliable methods for detecting anabolic steroids in the urine are now used in certain international competitions. Testing, announced bans, and disqualifications have not been effective in controlling the use of the drugs. The best hope for doing so lies in continuing education of athletes and their supervisors.

Muchos estudios de la vitamina E (por vía oral) han sugerido la inexistencia de beneficio para la prevención de la enfermedad cardiovascular. Además, existe evidencia reciente que sugiere que el uso regular de vitamina E en altas dosis aumenta el riesgo de muerte por cualquier causa en una pequeña proporción. Algunos expertos han criticado estas conclusiones y se ha sugerido la realización de ensayos en poblaciones de referencia más selectivas. El Estudio de la Salud de la Mujer informó una reducción de las muertes por causas cardiovasculares en las mujeres que tomaban vitamina E a diario (con un seguimiento de 10 años). Sin embargo, no hubo cambio en el índice o número total de muerte por ataques cardíacos o accidentes cerebrovasculares. Se necesita más investigación.

Las lesiones en un hueso sesamoideo—que pueden involucrar los huesos, tendones y/o tejido circundante en la articulación— están, a menudo, asociados con actividades que requieren una mayor presión en la bola del pie, tales como correr, jugar baloncesto, fútbol, golf, tenis y ás, las personas con arcos altos están en riesgo de desarrollar problemas con los huesos sesamoideos. Frecuentemente, el uso de zapatos de tacones altos puede ser también un factor que contribuya a este problema.

Even though anabolic steroids do not cause the same high as other drugs, they can lead to addiction. Studies have shown that animals will self-administer steroids when they have the chance, just as they do with other addictive drugs. People may continue to abuse steroids despite physical problems, high costs to buy the drugs, and negative effects on their relationships. These behaviors reflect steroids' addictive potential. Research has further found that some steroid users turn to other drugs, such as opioids, to reduce sleep problems and irritability caused by steroids.
