Physical exertion can cause folks to make some unpleasant noises, and the tennis world isn't going to take it anymore. "It's time for us to drive excessive grunting out of the game for future generations," World Tennis Association chairman and chief executive Stacey Allaster said. A slew of tennis organizations have agreed to start implementing anti-grunting measures, such as educating younger players on how to play more quietly and creating a handheld device "for umpires to objectively measure on-court grunting levels." Male grunting hasn't been raised as a problem, by the way. "The women are definitely louder and more abrasive," said Martina Navratilova, who has apparently never grunted.
