Anabolic androgenic steroids (AAS) were initially created for therapeutic purposes, and synthetic derivatives of the male hormone testosterone. Due its great anabolic effects, these drugs are being used on a large scale, for the improvement of sports performance. In this present study, we aim to show the history of it’ use, present their mechanisms of action, more particularly its use correlate with improved body composition, muscle mass, aerobic capacity and verify their possible side effects, analyzing their use therapeutic and indiscriminate, through direct scientific research with the sports. Sources were reviewed scientific the following search engines: PUBMED, LILACS and SCIELO. The results showed that in presence of a suitable AAS and diet can contribute to increases in body weight, particularly lean body mass and muscle strength gains achieved by high intensity exercise, these effects can be further potentiated, the use of supraphysiological doses, but in the aspect of aerobic power, there are not scientific evidence to support their improvement. Regarding side effects, the use of AAS, is related to several complications in the liver, cardiovascular system, reproductive system and psychological characteristics, always assigned by the non-therapeutic and abuse of AAS. Thus we conclude that the use of AAS, are directly linked to gains muscle mass, strength, as well several side effects, always assigned to abusive and indiscriminate doses, it is noteworthy that the scientific literature, still has a certain lack of studies, mainly randomized, controlled, with supraphysiological doses in human, so many effects are still unknown.
The topic of my master’s thesis evolved not only from my own interest and fascination of jacquard weaving. A little bit of luck contributed to the final outcome of this study as well. At an early point of my study, I wanted to discuss the material and col-our design of woven textiles. I considered various ways on how to approach the subject from a fresh and meaningful point of view. In the beginning of the spring of 2014, I spent three months on an internship at the Italian weaving mill Lodetex. Lodetex is specialized in the production of jacquard fabrics for furnishing markets. I decided that doing my thesis in collaboration with Lodetex would be a viable continuum after working in the company as an intern. I discussed the matter with owner Luca Farhanghi and he agreed that a thesis collaboration would be interesting and beneficial for the both of us. He informed me about a few production lines that the company planned on developing. One of these lines related to clipped designs. To me, the development of clipped designs seemed like a fascinating and interesting topic to research. Since I had already designed two clipped designs during my internship, I realized that the weaving process of these fabrics required more advanced technical understanding in interwoven structure of cloth. Therefore, this project gave me a chance to improve my skills in artistic expression as well as develop my knowledge in designing, weaving and finishing of clipped cloths.
