Context_1 : The Report to the Commissioner of Baseball of an Independent Investigation into the Illegal Use of Steroids and Other Performance Enhancing Substances by Players in Major League Baseball, informally known as the "Mitchell Report," is the result of former Democratic United States Senator from Maine George J. Mitchell's 20-month investigation into the use of anabolic steroids and human growth hormone (HGH) in Major League Baseball (MLB). The 409-page report, released on December 13, 2007, covers the history of the use of illegal performance-enhancing substances by players and the effectiveness of the MLB Joint Drug Prevention and Treatment Program. The report also advances certain recommendations regarding the handling of past illegal drug use and future prevention practices. In addition, the report names 89 MLB players who are alleged to have used steroids or other performance-enhancing drugs. Context_2 : A designer drug is a structural or functional analog of a controlled substance that has been designed to mimic the pharmacological effects of the original drug, while avoiding classification as illegal and/or detection in standard drug tests. Designer drugs include psychoactive substances that have been designated by the European Union as new psychoactive substances (NPS) as well as analogs of performance-enhancing drugs such as designer steroids. Some of these were originally synthesized by academic or industrial researchers in an effort to discover more potent derivatives with fewer side effects and were later co-opted for recreational use. Other designer drugs were prepared for the first time in clandestine laboratories. Because the efficacy and safety of these substances has not been thoroughly evaluated in animal and human trials, the use of some of these drugs may result in unexpected side effects. Context_3 : The use of performance-enhancing drugs (doping) is prohibited within the sport of athletics. Athletes who are found to have used such banned substances, whether through a positive drugs test, the biological passport system, an investigation or public admission, may receive a competition ban for a length of time which reflects the severity of the infraction. Athletes who are found to have banned substances in their possession, or who tamper with or refuse to submit to drug testing can also receive bans from the sport. Competitive bans may also be given to athletes who test positive for prohibited recreational drugs or stimulants with little performance-enhancing effect for competitors in athletics. The sports body responsible for determining which substances are banned in athletics is the World Anti-Doping Agency (WADA). Context_4 : The Biogenesis baseball scandal broke in 2013 when several Major League Baseball (MLB) players were accused of obtaining performance-enhancing drugs ("PEDs"), specifically human growth hormone, from the now-defunct rejuvenation clinic Biogenesis of America. After an ex-employee annoyed over missing back-pay revealed clinic records that were "clear in describing the firm's real business: selling performance-enhancing drugs", MLB sued six people connected to Biogenesis, accusing them of damaging the sport by providing banned substances to its players. In July, thirteen involved players received lengthy suspensions of fifty or more games (nearly a third of a season). Context_5 : Banned substances in baseball has been an ongoing issue for Major League Baseball. Several players have come forward in recent years to suggest that drug use is rampant in baseball. David Wells stated that "25 to 40 percent of all Major Leaguers are juiced". Jose Canseco stated on "60 Minutes" and in his tell-all book "" that as many as 80% of players used steroids, and that he credited steroid use for his entire career. Ken Caminiti revealed that he won the National League MVP award while on steroids. In February 2009, after reports emerged alleging that Alex Rodriguez tested positive for steroids in , a year in which he was American League MVP, he admitted to having used performance-enhancing drugs (PEDs) between and 2003. Mark McGwire, dogged by allegations of PED use for years, admitted in January 2010 that he had used steroids and human growth hormone off and on for over a decade, including in when he set the single-season home run record. Context_6 : Natural bodybuilding is a bodybuilding movement with various competitions that take place for bodybuilders who abstain from performance-enhancing drugs. This categorically excludes the use of substances like anabolic steroids, insulin, diuretics and human growth hormone. If a bodybuilder meets the requirements of the sanctioning body (the recognized group or authority that sanctions and validates competitions) that they are competing in, then they are considered to be "natural". There are numerous sanctioning bodies who provide their own rules and regulations that govern the competition procedures, event qualifications, banned substance lists, and drug testing methods. Doping detection methods include urinalysis and polygraph testing, and federations typically conduct these tests on the day of competition, or shortly before. Out-of-season testing, although less common, may also be used. Each organization will specify within its rules the length of time that its athletes should be drug-free, which may vary from testing clean on the day of the event, to being drug-free for a number of years, right up to a lifetime natural requirement. Context_7 : Performance-enhancing substances, also known as performance-enhancing drugs (PED), are substances that are used to improve any form of activity performance in humans. A well-known example involves doping in sport, where banned physical performance–enhancing drugs are used by athletes and bodybuilders. Athletic performance-enhancing substances are sometimes referred to as ergogenic aids. Cognitive performance-enhancing drugs, commonly called nootropics, are sometimes used by students to improve academic performance. Performance-enhancing substances are also used by military personnel to enhance combat performance. Context_8 : This article is about the history of competitors at the Olympic Games using banned athletic performance-enhancing drugs. Context_9 : In competitive sports, doping refers to the use of banned athletic performance-enhancing drugs by athletic competitors, where the term "doping" is widely used by organizations that regulate sporting competitions. The use of banned drugs to enhance performance is considered unethical, and therefore prohibited, by most international sports organizations, including the International Olympic Committee. Furthermore, athletes (or athletic programs) taking explicit measures to evade detection exacerbates the ethical violation with overt deception and cheating. Context_10 : The Spanish Anti-Doping Agency, officially Spanish Agency for Health Protection in Sport (AEPSAD), is a Spanish agency responsible for the protection of the right to health of all the athletes and the protection of the right to participate in a competition without cheats. fact_1 : The Spanish Anti-Doping Agency, officially Spanish Agency for Health Protection in Sport (AEPSAD), is a Spanish agency responsible for the protection of the right to health of all the athletes and the protection of the right to participate in a competition without cheats. fact_2 : In competitive sports, doping refers to the use of banned athletic performance-enhancing drugs by athletic competitors, where the term "doping" is widely used by organizations that regulate sporting competitions. Answer: athletic competitors
Output: This Spanish agency is responsible for the protection of the right  to participate in a competition without  the use of banned athletic performanceenhancing drugs by who?
