The immediate past president of the International Olympic Committee, Thomas Bach, served for 12 years with this elegant guiding notion: “unity in diversity.”\

Six years ago, Bach wrote a column published in The Guardian, the British newspaper, that read, in part: “The Olympic Games cannot prevent wars and conflicts. Nor can they address all the political and social challenges in our world. But they can set an example for a world where everyone respects the same rules and one another.”

The new IOC president, Kirsty Coventry, elected in March, faces enormous challenge in delivering on the aspirational promise of the Olympics that Bach articulated so eloquently. 

That mission is at grave risk because the government of Indonesia is not allowing a six-member Israeli team to compete in the world gymnastics championships due to begin next week in Jakarta.

The IOC’s mission then is the mission now: to put sport at the  “service of the harmonious development of humankind, with a view to promoting a peaceful society concerned with the preservation of human dignity,” as it says in the Olympic Charter. 

Until Thursday, in the women’s 400, only two women had gone under 48 seconds, both from the 1980s — Marita Koch of East Germany and Jarmila Kratochvilová of what was then Czechoslovakia. Koch went 47.60 in 1985. Two years earlier, at the 1983 worlds in Helsinki, Kratochvilová went 47.99.

Until Thursday, that was the championship record.

Sydney McLaughlin-Levrone crossed in 47.78.

Marileidy Paulino of the Dominican Republic, the Paris 2024 Olympic and 2023 worlds champion, finished in 47.98 — one-hundredth faster than Kratochvilová. But good enough only for second.

The female category in sport is for women and girls – individuals with XX chromosomes.

Identity is not biology.

To pretend otherwise is not only to make a mockery of any notion of fairness but, in the case of boxing, risk serious injury or worse.

Now, with Algeria’s Imane Khelif said to be on the verge of returning to competition, World Boxing has announced that Khelif, winner of a gold medal at the Paris Games, must take a chromosome test to prove eligibility – in its words, undergo “mandatory sex testing.” 

COSTA NAVARINO, Greece – The International Olympic Committee, founded in 1894, has had nine presidents.

All have been white men. Eight have been Europeans. Avery Brundage, 1952-72, was American.

On Thursday, in just a single round of voting, the IOC elected Kirsty Coventry, 41, of Zimbabwe, its 10th president. She will formally take over from Thomas Bach in June in Lausanne. He was elected in 2013 and is termed out.
