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.

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.

• 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.

• 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 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.
