Limits and Interface in Science Humboldt-Kolleg Sao Paulo, 28-30 November 2009 Gene Doping Prof. Dr. Eduardo Henrique De Rose Porto Alegre, Brazil
Summary of the presentation • Short history of doping in sports; • Modern definition of doping; • The future of doping: gene doping; • Genetically based therapy and span; • Selection of talents; • Exemples of gene doping; • Future possibilities; • Conclusion.
Why I choose Germany? 1911 – Physiology Laboratory presented in Dresdner; 1912 – First Sports Medicine Association founded; 1913 – Mallwitz receives the title of Sport Physician; 1917 – First Physical Education School founded; 1924 – First Sports Medicine Journal; 1928 – Foundation of FIMS in Saint Moritz, Switzerland.
Olympic Games of 1936 in Berlin, Germany.
Actual definition of doping • Increases artificially the performance; • It is a risk for the health of the athlete; • It is contrary to the spirit of sports. When two of the top three criteria are present, we have a case of doping.
Genethically based therapyes are being developed and it will change soon the epidemiology of the diseases as we know it.
Detection of Talents • The detection of talents is actually done by observation of external anthropometric characteristics and in tests in Laboratories of Human Performance; • The human genetically map will permit, studying the related phenotypes of a child, to detect a predisposition for a specific activity.

Myostatin • The Belgian Blue Bull demonstrates the effect of blocking the antigrowth factor myostatin. A natural genetic mutation in this breed produces a truncated, ineffective form of myostatin, which allows muscle growth to go unchecked. The absence of myostatin also interferes with fat deposition, making these “double-muscled” cattle exceptionally lean.

Genetically Engineered "Marathon Mouse" Keeps On Running Genetically Engineered "Marathon Mouse" Keeps On Running By enhancing the function of a single protein, Howard Hughes Medical Institute researchers have produced a “marathon mouse” with altered muscle composition and enough physical endurance to run twice as far as normal mice.
