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.
Jesus Dapena is a Professor for the Department of Kinesiology with Indiana University. He is based in Bloomington, Indiana.
