Fifty-three years ago today, on August 26, 1972 (July 18, 1972), the 20th Olympic Games opened. La Veren (second from right) won gold medals in the 5,000-meter and 10,000-meter runs at the Munich Olympics, and four years later he won the championship in both events. As times have changed, political interference (interference by politicians in sports, disputes over racial issues, ethnic conflicts, etc.) has increasingly become an obstacle to the healthy development of Olympic sports. On September 5, 1972, during the 20th Olympic Games, eight Palestinian "Black September" terrorists stormed the residence of the Israeli delegation, kidnapped and killed 11 Israeli athletes, leaving Munich in an atmosphere of sadness. The Americans lost in the men's 100m and 200m for the second time in nearly 40 years. They were eliminated in the 4xl00-meter relay preliminaries, the first time since the event was included in the Olympic Games. The gold medal was taken away by the unknown Kenya team. But Short's victory in the marathon brought a little comfort to the US team's successive defeats. La Veren once again established Finland's image as a "country of long-distance running" in the 5,000-meter and 10,000-meter runs, and he won both four years later. The African lions suffered badly in the long-distance running event, but Uganda's Aki Bua unexpectedly won the 400-meter hurdles. All these surprises show that a country does not have "eternal" events. All the gold medals in women's track and field events were won by European athletes. The gold medal in the women's 1500-meter run, which was included in the Olympic Games for the first time, was taken away by Brajina of the Soviet Union. She broke new world records in the pre-summer, summer and finals, which showed that women have unlimited potential in middle and long-distance running, laying the foundation for the women's middle and long-distance running to be finally included in the Olympic Games. Stscher, a 20-year-old GDR runner, won 2 gold medals and 1 silver in the 100-meter, 200-meter and 4xl00-meter runs. Thanks to the attention and support of the country, the national sports and fitness of the GDR has been widely developed since the 1960s, and the sports performance has improved rapidly. From 1 gold medal at the 1956 Melbourne Olympic Games to 20 gold medals this year, it has created a real leap. Spitz of the United States broke world records in the 100-meter, 200-meter freestyle and 100-meter, 200-meter butterfly and three relays, winning a total of seven gold medals. Together with two in the previous two editions, Spitz became the third athlete in Olympic history to win nine gold medals. Yoo Bragina won the first Olympic gold medal in women's 1500-meter running at the Munich Olympics. Nine Olympic gold medalist Mark Spitz
