Recently, the United States Pennsylvania University researchers found that mice through gene therapy is injected with a GM ever virus (the virus into the muscle tissue and causes the cells to grow rapidly), muscle size, strength, endurance, etc. Then someone asked, if similar experiments in human body will produce the same effect? if so, the "to" the following will most likely happen: the biotechnology is likely to be unlawfully used to develop a "super" players.
Engaged in the research of the University of Pennsylvania's Lee Sweeney and others would have aimed for the treatment of muscular dystrophy and increased with age caused by muscle weakness. Sweeney said that their experiment shows: injection to experimental rat muscle in the reformed the virus contains substances that produce such IGF1 gene and IGF1 makes the size of experimental rat muscle and strength increased 15 per cent to 30 per cent. But when this technology to participate in physical fitness training project of mice, rats and muscle strength doubled. "If a normal human being injection-related material, his muscles can be trained to become more powerful. If the person is to participate in the training of athletes, the study indicates that his training will become more effective, training brings harm to more easily cured, the training effect will last longer. "In addition, the study also showed that the experimental effect in experimental rats throughout its period.
In mice of the preliminary results, is used in the human body as a matter of time. Thus a recent United States Sweeney AAAS annual meeting expressed the same concern: "we now deal with the study of disease in the future one day it may be used to enhance sports performance. "Other research organization of Tom Murray also believes that the gene therapy for athletes like allow certain athletes wearing Skate Marathon. It is understood that Murray had on competition do in-depth research, he said: "in order to pursue a better score, players use drugs and gene therapy has the potential to use by athletes. There is no doubt that if players know Sweeney research undertaken, would contact him. The result is the result of illicit means and prohibited means ' struggle ' fiercer! "for Murray, Sweeney recognized that he had received about half of the e-mail is from athletes or coaches.
Sweeney said, and other drugs to improve athletic performance, gene therapy results will not be blood test, test papers, and other means. To test athletes participated in gene therapy, you must obtain a specific muscle of living tissue, and placed in the DNA Labs to mature detection.
You can imagine, sports officials on the most repugnant, in their view, gene therapy have let players to betray the spirit of the potential of pure sports spirit is athletes use was born with the physical talent plus acquired training hard to fight for "faster, higher, stronger". McGill University, the world anti-doping Association of Richard Pound said: "the international sports community has in the last century, 60 ~ 90 s almost impossible to control the player to improve your score and the use of prohibited drugs. With regard to these practices, we've done a lot of work. But now, gene therapy is a very serious threat. "
Even if all these arguments have already started to think that due to various factors in the Sweeney, this enhanced muscle strength of gene therapy also after several years before they can use. He said that the technology used in the human body, his laboratory hopes to develop a gene can be made at any time switch technology. In other words, once there is a problem, genes can be turned off. Experts, gene therapy in the treatment of many diseases of the very important role, but in many countries, this approach also subject to strict control. Sweeney said gene therapy is very complex and require specialized laboratories of long-term research can gradually moving towards maturity.
Sweeney felt that many countries in order to get the medals that will be possible acquiescence athletes using gene therapy, as the Olympic movement through early many countries allow taking drugs improve your score. However, gene therapy is not a player a man can do, you need the help of many people. More importantly, this role through external change his body, and thus improve sports performance practice is harmful, short-sighted.
