homozygous mice

Myostatin
  • A growth factor (hormone) that surpresses muscle
    growth.
  • Slows down development of muscle stem cells
  • In 2002, researchers at the University of
    Pennsylvania showed that monoclonal antibody
    specific to myostatin improves the condition of
    mice with muscular dystrophy, presumably by
    blocking myostatin's action.

Carl Lewis
  • Ran 100 m in 9.86s
  • 1991 world record
  • Jumps over cars
  • 9 Gold Medals
  • Excellent example of Type II fast twitch muscle
  • Also a vegan
  • Outspoken, even damning of those who used
    performance enhancers.
  • Like Ben Johnson

6
Ben Johnson
  • Between 1968 and 1983 the 100m record was shaved
    by 0.04s
  • In one year Johnson beat it by 0.16s
  • 1988 Seoul Olympics
  • Johnson 9.76 s
  • 27 mph
  • 45 strides
  • Ahead the whole time
  • Lewis sets an American record with 9.92s, but
    still second
  • Busted for doping

7
Back to Carl Lewis
  • Johnsons medal revoked and given to Lewis
  • 5 years later in 2003 Lewis admits he was busted
    3 times in 1988 for banned stimulants.
  • He thought they were herbal supplements
  • The U.S. Olympic committee found his ingestion to
    be, inadvertant
  • Since it was after the 3 year statute of
    limitations he could keep his medals
  • Stimulants could have masked more serious
    steroids from tests
  • Johnson beating Lewis in 88

8
Which leads to the question how do steroids work?
  • Androgenic increasing masculine traits
  • Anabolic building muscles as opposed to
  • Catabolic breaking down nutrients
