Sprained ankles are relatively common in tennis players. Roger
Federer, Andy Roddick and Andrew Murray have all suffered
sprained ankles. The sudden sideways movements that are required
during tennis can cause the ankle to twist, particularly if the
surface is slippery or the player is fatigued. A twisted ankle
causes damage to ligaments and other soft tissues around the
ankle. This is called a Sprained Ankle. The damage causes
bleeding within the tissues, which produces a swollen ankle that
can be extremely painful. What can you do to prevent Sprained
Ankles? Applying an ankle brace to the ankle can help to reduce
the risk of ankle sprains and it's a strategy that is employed
by tennis pros such as Andrew Murray and Roger Federer. Previous
research has shown the injury incidence in people with taped
ankles was 4.9 ankle sprains per 1000 participant matches,
compared with 2.6 ankle sprains per 1000 participant matches in
students wearing ankle braces. This compared with 32.8 ankle
sprains per 1000 participant
