So my sister and I are on the same soccer team and she sprained her ankle and she isn't allowed to play any more. I was wondering if anyone could give me a list of things to avoid doing so I can keep playing soccer?

Everything.

You can sprain your ankle just walking down the street.

If you're really worried you should try bracing your ankle when you play soccer or do sports activities. I think they sell basic ankle braces at most drug stores.

But, really I don't think it's necessary. Accidents happen, you can't live your life worrying "what if something bad happens?" And though sprains are painful and can sometimes be worse than a broken bone as far as muscle damage, they do heal eventually and most people are able to return to their prior sporting ventures.

It's true that a sprained ankle can happen to just about anyone and probably happens to most people at some point or another in life. That said, as an athlete there are things you can do to lessen the likelihood.

First, wear proper shoes for your sport. Your shoes need to fit and have proper traction, so you need decent cleats that are designed for the surface, whether natural or artificial turf, that you are playing on.

Second, warm up and stretch properly per your coach. Don't blow off warm up or stretching exercises when you play or practice as many kids, and even adult athletes do - when you do, you are more prone to injury.

Third, train in agility, both with your team and on your own. Agility training improves the quickness of your footwork and responsiveness and also improves your balance and sure footedness when you change directions and otherwise respond to the game. When you are more skilled at your footwork, you are less likely to misstep and hurt yourself.

It's important to understand that sports and injuries go together. Most athletes suffer injuries of one type or another at some point and it is a hassle. By staying fit and strong, nimble and balanced, by doing proper workouts, you can lessen the chance of injury. Also wearing whatever safety gear is recommended for your sport, like shin guards, is important.

You can't fully prevent getting hurt or sick so just do what's sensible and then put it out of your mind. Your sister's ankle will heal and she will play again when it does - a sprain is not a career-ending injury.
