It's commonly said that sports are 90 percent mental and only 10 percent physical. A lack of focus can result in a missed three-point shot, nerves can cause a gymnast to fall out of her landing, and a momentary lapse in confidence can easily make the difference between gold and bronze. So it's no surprise that some of the best professional athletes in the sports world are turning to meditation -- which has been shown to reduce stress and improve focus -- to boost their game and ease the anxiety of high-pressure performances.

Athletic greats Joe Namath, Barry Zito and Arthur Ashe have spoken out about the benefits of meditation as a tool for athletic success. And even entire teams have been turning to visualization and mindfulness practices.

Click through the slideshow below for seven professional athletes (and one college basketball team) who meditate to improve their game.
