Narrator: This is Science Today. With the advent of warmer weather, there's a higher risk of foot and ankle injuries. Dr. Keith Donatto, a professor of orthopaedic surgery at the University of California, San Francisco, says after being cooped up indoors all winter, many weekend warriors have not prepared the muscles used in sports with lots of running and jumping.
Donatto: Tennis, soccer and jogging are some of the more common activities that people participate in and in all of those sports, ankle sprains are the most common injury.
Narrator: To avoid injury, prevention is key - whether it be doing warm-up stretches or picking the right shoe for each activity.
Donatto: But really what it boils down to is that conditioning prevents injury. And participation at a level of competition that you're comfortable with also avoids injury. So, depending on what sport you are in, the warm-up period may last anywhere from five to even fifteen minutes. It just depends on your body habit.
