Too bad 80 percent of girls drop out by middle school-not sure why, but there was a recent study that showed at middle school, most girls stop playing sports...I think part of it is b/c the comp teams do their picking and kids feel the pressure if they are in rec to just quit if they aren't going to be in a comp team...Also, more homework pressures etc.
Yes, it's a shame that so many girls quit playing at an early age. I have coached for many years, the last 15 years or so with just girls. There is a big difference. I have often said that boys will play for whichever coach walks in with a whistle around his neck. Girls, however, want to know their background, mother's maiden name, shoe size, etc. In the end, most girls want to play to have fun. That's why I enjoy coaching them so much. They want to win but are not devastated if they don't. They want to enjoy the sport for the camraderie. Of course, I have seen many who do it out of their competitive nature so I hate to generalize. Regardless, the best way to keep girls engaged in sports is for them to have fun. This means that there needs to be extracurricular (non-game/practice related) activities for the team.
Also, far fewer girls start playing sports at a young age than do boys. This means that, when one drops, the percent of player reduction is greater. Girls are then often reluctant to try something new at a later age for fear of failure. Sports can be just the ticket as it can give girls greater confidence, which is especially important for girls as they face pressures not felt by boys.
