Evgenia Novozhenina/Reuters Only four swimming world records were broken at the Paris Olympics, the fewest since 1996. Experts pondered if turbulent water in the shallower pool — 2.15 meters (7 feet), less than the recommended 3 meters (9’10”) — was the cause, although it may be a hangover from the 2008 Beijing Games, where now-banned super swimsuits led to 25 new world records. They are just some of several tech-assisted records that some commentators consider tainted. Records may be becoming more uncommon anyway, partly because athletes are inching closer to human limits, and because peak performance is more difficult in hot weather: Thanks to global warming, Paris may break a world record of its own, taking Tokyo 2020’s title as the hottest Olympic Games in history. |
