ZAGREB, YUGOSLAVIA, JULY 13 -- Noemi Lung of Romania captured her fifth gold medal in swimming and three Italians swept the first medals in track and field as the 14th World University Games entered their second week.

The 18-year-old Lung broke her third record of the Games with a time of 8:34.82 in the 800-meter women's freestyle. The old record of 8:37.50 was set by American Kim Linehan in 1981.

Raffaello Ducceschi, a 26-year-old Italian, broke away from teammate Giacomo Poggi with about one kilometer left in the 20-kilometer walk to win in 1 hour 25 minutes 2 seconds. Poggi was about 30 meters behind, with another Italian, Pierluigi Fiorella, third.

Lung easily beat Cheryl Kriegsman of Los Angeles, who finished second, almost seven seconds behind.

The East Germans are concentrating on the European championships in Strasbourg, France, next month. The top Americans are pointing toward the Pan American Games later this summer.

Americans won two more golds in swimming to increase their medal count to seven overall. The Soviet Union leads with 15 golds. Romania now has 12 golds.

Ann Drolsom of the University of Texas won the women's 50-meter freestyle in 26.24 seconds. She went one-hundredth of a second faster in a morning heat in the first-time event. "I never won nationals so this is the greatest victory in my life," Drolsom said.

It was only the second individual gold medal for the U.S. swimming team, which has four relay golds, including one today, in the men's 800-meter freestyle relay.

Jeff Olsen of Austin, Tex., moved past Frank Drost of the Netherlands to gain the gold for the Americans. Joe Parker of Battle Creek, Mich., Brent Lang of Portland, Ore., and John Hodge of Williamsville, N.Y., preceded Olsen. Their winning time was 7:29.30.
