Too much pressure takes all of the fun out of playing sports.

The American Academy of Family Physicians suggests these relaxation techniques to calm during-game jitters:

• Find a quiet spot to do some deep breathing. Take a deep breath in, hold it for five seconds, exhale and repeat.
• Flex a muscle group and hold it for about five seconds, then relax and release it. Do this five times with different muscle groups.
• Visualize a peaceful, relaxing scene. Picture all of the stress going out of your body. Try visualizing your success in the game.
• Think positively, instead of dwelling on mistakes or losses.
