Fill out personal and family history: Fill out the history completely and accurately. If you aren't sure about your family history, take time to ask. Request forms before your doctor's visit and fill it out at home where you will have access to your records.

A medical history isn't just paperwork; your genetic history and past health issues are the best way to predict your risk factors for many health issues.

Tell your doctor: Mention previous health issues while playing sports, such as blacking out suddenly while in the middle of a game, suffering from heat illness or having a concussion. These are serious concerns that may signal increased risk for future issues. In some cases, your doctor may want to do additional screening tests to make sure you're healthy enough to play.

Ask questions: Take the initiative and ask your doctor about any concerns or questions you have. This is also a good chance to ask questions about diet, sleep or other health issues. Before you leave your appointment, make sure you understand any instructions your doctor has given.

"Once we know an athlete is healthy enough to play, participating in a sport can be a very healthy activity," Mitchell said.
