Badminton is a sport for two (singles) or four (doubles) opposing players. Players score points by striking a shuttlecock with their racquet so that it passes over the net and lands in their opponents’ half of the court. The size of the shuttlecock as well as the field is strictly regulated by the rules. Not everybody knows that badminton is a hard psisical work for professional players. The most frequent injuries in this sport discipline are Achilles injuries, ACL injuries and muscles strains.
