Questions and Answers

What is gene doping?

  • Introducing new genes into tissues of the body to correct natural gene expression.
  • Manipulating the genetic heritage of an individual to enhance athletic performance.
  • Using genetic materials to improve nontherapeutic athletic performance. (correct)
  • The use of genes, genetic elements, or cells for therapeutic purposes in athletic performance.
  • How is athletic performance enhanced according to the text?

  • By manipulating the genetic heritage without any acquired skills.
  • Primarily through acquired skills gained through training and nutrition.
  • Through a combination of inherited genetic capabilities and acquired skills. (correct)
  • Solely through modifying genes using gene doping techniques.
  • What are some of the risks associated with gene doping?

  • Increased risk of intellectual traits being altered.
  • Alteration of natural gene expression in the body.
  • Unknown long-term health consequences and potential side effects. (correct)
  • No risks are associated with gene doping according to the text.
  • How does gene doping differ from assisted reproductive technology?

    Study Notes

    What is Gene Doping?

    • Use of genes, genetic elements, or cells for non-therapeutic purposes to enhance athletic performance
    • Involves modifying genes to improve physical traits, such as muscle growth and oxygen transfer

    Genetics and Athletic Performance

    • Human cells contain around 25,000 genes
    • Genetic heritage determines physical traits and athletic potential, as well as personality and intellectual traits

    Methods of Gene Doping

    • Modification of genes using viruses to introduce new genes into tissues
    • Non-viral methods involve using DNA alone (plasmids) to transfer genetic information
    • Gene editing: tiny alterations to DNA in existing genes to temporarily boost or switch off gene activity

    Risks and Concerns

    • Gene doping poses health risks and is unethical in healthy athletes
    • Techniques are powerful, effective, and difficult to detect
    • Risk/benefit ratio may be acceptable in patients, but not in normal healthy athletes

    Future of Gene Doping

    • Genetic methods will likely be used to modify conditions, such as preventing muscle degeneration in aging
    • Genetic enhancement of athletic performance in sport seems inevitable
    • Techniques and tools are immature and potentially harmful, and should be excluded from sport

    Preventing Gene Doping

    • Need for strict framework of use restricted to therapeutic and ethical use
    • Rules and safeguards must be established by governments to ensure ethical and safe use
    • WADA's actions: alerted scientific community to risks, organized workshops, provided financial support to research, and included gene doping in prohibited list

    WADA's Actions

    • 2003: banned use of genetically modified cells and gene therapy
    • 2018: included gene editing agents in prohibited list
    • Educational programs planned to prevent gene doping
