in
Amsterdam. At the
1928 Summer Olympics in
Amsterdam, Cook competed as a member of
Canada's first Olympic women's
track and field team. The Games marked the first time women's athletics events were included in the Olympic program, though their inclusion followed years of resistance and debate. Only five events were opened to women: the 100 metres, 800 metres, high jump, discus throw, and 4 × 100 metres relay. Many officials and physicians questioned whether women should compete in strenuous events at all. Some medical authorities warned that competitive athletics might harm women's health or reproductive capacity. One widely circulated claim held that "excessive athletic effort may seriously disturb the normal functions of the female body". Women's participation was also opposed by
Pierre de Coubertin, founder of the modern
Olympic Games. Coubertin believed the Games should remain a predominantly male arena and argued that women's role in sport ought to be limited. Writing in 1912, he described women's Olympic participation as "impractical, uninteresting, unaesthetic, and incorrect", and maintained that the Olympic Games should be "the solemn and periodic exaltation of male athleticism". Pressure for inclusion came largely from women's sporting organizations. In the early 1920s, French sports leader
Alice Milliat organized the
Women's World Games, international competitions that demonstrated both the popularity and competitive standard of women's athletics. Their success placed increasing pressure on Olympic officials, who eventually agreed to introduce a limited program of women's athletics at the 1928 Games. Cook arrived in Amsterdam as one of the favourites in the
100 metres. At the Canadian Olympic trials in
Halifax, Nova Scotia, in July 1928 she ran 12.0 seconds, equalling the world record. The victory secured Canada's first Olympic gold medal in women's track and field and helped offset the disappointment of Cook's disqualification in the 100 metres final. The 1928 Games proved to be a turning point for women's athletics. Canada had sent only seven women to the Games, six of them in track and field, yet they won four medals, an achievement that led the press to celebrate them as the "Matchless Six". Their performances helped establish Canada as a leading force in women's sprinting. ==Post-Olympic career==
