The high altitude of Mexico City (2240 m) made it difficult for many endurance athletes to adapt to the oxygen-deprived air. The high altitude was also credited with contributing to many record setting jumps and leaps in the long jump, high jump and pole vault events, as well as all the track events 400m and under (men's). Bob Beamon jumped 8.90 m in the long jump a 55 cm improvement of the world record that would stand until 1991(when it was broken by Mike Powell); it is still the Olympic record. United States athletes Jim Hines and Lee Evans also set long world records in the 100 m and 400 m, respectively. For the first time in Olympic history Doping test was conducted in Mexico Olympics.

Swedish pentathlete Hans Gunnar Liljenwall was diqualified for alchol use. As many as 112 nations graced the games.

The first Olympic mascot was the dachshund 'Waldi' of Munich Olympics.However, this joyful mood of the games was ruined by the killings of 11 Israeli athletes by Palestinian terrorist in an event known as the "Munich massacre." Mark Spitz, a swimmer from the United States, set a world record when he won seven gold medals (while on the way to setting a new world record for each of his seven gold medals) in a single Olympics, bringing his lifetime total to nine (he had won two golds in Mexico games four years earlier).The United States also lost an Olympic basketball game for the first time ever (they were 62-0) when the Soviets were given three chances to convert a last-second inbound pass and finally won, 51-50. The U.S. refused the silver medal.
Canada, the host country, left with only five silver and six bronze medals in this Olympics. It was the first and only time to date in Olympic history that the host country of the Summer Games won no gold medals.

India won thier a last title in men's hockey in Moscow Olympics
1984-Los Angeles Olympics:
Soviet Union and 13 Communist allies boycotted Los Angeles Olympics in an obvious payback for the West's snub of Moscow in 1980. As a result, the United States won a record 83 gold medals in the most lopsided Summer Games since St. Louis .The American gold rush was led by 23-year-old Carl Lewis, who broked Jesse Owens' 1936 track and field grand slam by winning the 100 and 200 meters and the long jump, and anchoring the 4x100 meter relay. Romanian gymnast Ecaterina Szabó matched Lewis' four gold medals and added a silver, but the darling of the Games was little , 16-year-old Mary Lou Retton, who won the women's All-Around with a pair of 10s in her last two events.
