Rosa Mota of Portugal again won the women's marathon and Salvatore Antibo of Italy dominated the men's 10,000 meters as the European Championships opened in Split, Yugoslavia.

Mota, 32, the world and Olympic champion, has not lost a major marathon in five years, but she had a tough time garnering her record third straight European title.

After building a two-minute margin at 12.4 miles, she was slowed by the heat and stomach pains and eventually was caught by Valentina Yegorova of the Soviet Union. Yegorova stayed with Mota only a few strides, however, before Mota pulled away and eventually won by 30 meters in 2 hours 31 minutes 27 seconds.

Antibo came down the homestretch blowing kisses and waving to the crowd, winning in 27:41.27. In a sprint for second place, Are Nakkim of Norway beat Stefano Mei, the defending champion from Italy, 28:04.04 to 28:04.46.

Astrid Kumbernuss, 20, of East Germany, competing in her first big event, upset Olympic champion and world record holder Natalya Lisovskaya of the Soviet Union in the women's shot put. Kumbernuss threw 66 feet 10 1/2 inches. Lisovskaya was second at 65-9 3/4, Kathrin Neimke of East Germany third at 65-6.

Former javelin world record holder Jan Zelezny of Czechoslovakia was eliminated in the qualifying, his best fling 14th with only the top 12 advancing. The best toss was a meet-record 280-5 by Einar Vilhjalmsson of Iceland.
