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.
Thanks so much for this post. I’m putting together a Reading Binder / (future) teacher resource for my son and daughter-in-law and their 1-year-old son. I have an AAS degree in Early Childhood Education (PreK), but in our classes we never did go through exact steps on HOW TO teach reading, just mainly the importance of reading and developmental levels of the young child. I started homeschooling my youngest of four only after her third grade year. So, I’m in the learning phase, myself, as to the formal HOW TO part of teaching reading to a child. I’ll be definitely adding this information to the binder, including the comments, since there’s such great info in all. I’ve seen “How to teach your child to read in 100 Easy Lessons” referenced in various blogs and homeschooling videos with mixed reviews as listed in comments above. I ran across “Starfall” and “Sing, Spell, Read, Write”, in my initial homeschooling resources research and liked what I saw. I’m reading a lot of good reviews/reports on the “Bob books” from my research. One year we bought the subscription to “Reading a-z” (readinga-) -(where you can print off books and assemble them at home) and to the accompanying on-line reading program “Raz-Kids” (raz-), then the next year we just kept the “Raz-Kids” to reduce the cost. These were pricey for a homeschooler, as the subscription was for a whole class, but there were more books available at levels a-z than we could have ever purchased individually, in addition to all sorts of matching printables, etc. It was good for me to use, since it gave me the ability to place her at the appropriate level or bounce between levels (if needed) while I figured out the whole ‘homeschooling thing’. We didn’t have the finances to keep up the subscription, but for me…I loved the ability for her to do on-line recorded readings that I was able to go back and mark and grade. Comprehension tests were available, as well. All the various printable features for grading ‘reading’ was beneficial to me, as the teacher. It provided a concrete way for me to provide a grade through the recorded readings, comprehension tests, and fluency test features. Reading a-z / Raz-Kids is a good program for kids who have already passed through the beginner stages of the reading process. I never really checked out the A,B,C,D,E,F stages of the program, as my daughter was already reading when we bought the subscription, so I can’t attest to how the program works in the beginning levels. But, overall, I loved the overall program and wish I could afford both subscriptions, again. I look forward to checking out some of the other resources listed in the comments. Thanks fellow homeschooling moms for the great input! 🙂
