× 400, however, the United States cruised to victory while equaling the 20-year-old world record which had been set in Mexico City. In men's field events, the highlight came from Carl Lewis defending his gold medal from Los Angeles and leading the United States to a medal sweep in the long jump. In the women's events, Florence Griffth-Joyner had dominating performances in the 100 and 200 meter sprints, lowering the Olympic record by over 0.2 seconds in the 100 and lowering the world record by almost 0.4 seconds in the 200. She also helped the United States to strong performances in the relays, winning gold in the 4 × 100 and coming in second, while beating the previous world record, to a record-shattering performance by the Soviet team in the 4 × 400. Meanwhile, in the heptathlon, Jackie Joyner-Kersee dominated the competition while setting a world record that has not been approached in the succeeding 30 years. Joyner-Kersee's long jump performance in the heptathlon was enough to set the Olympic record for the discipline, only for her to eclipse it in the final of the long jump event. The high jump event also saw Louise Ritter eclipse the Olympic record on the way to a gold medal. Finally, the only United States medal in the middle distance events came from Kim Gallagher, who captured bronze in the 800 meters.
