Tehran University of Medical Sciences Iranian Journal of Public Health 2251-6085 40 1 2011 03 15 1 14 AA Fallahi Fallahi AA Ravasi Ravasi DD Farhud Farhud 2015 10 03 Background: Use of genetic doping or gene transfer technology will be the newest and the lethal method of doping in fu­ture and have some unpleasant consequences for sports, athletes, and outcomes of competitions. The World Anti-Doping Agency (WADA) defines genetic doping as "the non-therapeutic use of genes, genetic elements, and/or cells that have the capac­ity to enhance athletic performance". The purpose of this review is to consider genetic doping, health damages and risks of new genes if delivered in athletes. Methods: This review, which is carried out by reviewing relevant publications, is primarily based on the journals available in GOOGLE, ELSEVIER, PUBMED in fields of genetic technology, and health using a combination of keywords (e.g., ge­netic doping, genes, exercise, performance, athletes) until July 2010. Conclusion: There are several genes related to sport performance and if they are used, they will have health risks and sever dam­ages such as cancer, autoimmunization, and heart attack. https://ijph.tums.ac.ir/index.php/ijph/article/view/3059 https://ijph.tums.ac.ir/index.php/ijph/article/download/3059/2858
