The world record for high jump — the event in which a person hurdles himself over a horizontal bar — is just over 8 feet. That's like leaping over a stop sign, and clearing it by a foot. Jesus Dapena, of Indiana University, has studied the high jump for 30 years, filming athletes to understand exactly how they produce the force required to clear the bar.
