One of the most iconic sounds in all of professional sports is the grunt heard during a women's tennis match. While grunting has been around since at least as far back as the 16th century, it was only popularized in modern-day tennis by legendary player Monica Seles. After winning her first Grand Slam title at age 17, Seles began to make use of loud grunts while playing in 1990 and this quickly caught on with other players. The practice became commonplace among female competitors for years until recently when some tournaments have begun to punish those who grunt too loudly or too often. Despite this, there are still many players today who continue to make use of grunting as an effective method for improving their performance on court.
