Concussions in professional rugby union are the most common injury received. Concussion can occur where an individual experiences an impact to the head, and are also notable in high-contact sports, including American football, boxing, MMA and Hockey. Concussions can occur in recreational activities like horse riding, jumping, cycling, and skiing as a result of forceful rotational moment, resulting in injuries to the brain due to the contact with the skull, giving the skull not enough time to move with the body, causing the brain to press against the skull. With the development of equipment and training methods, further education on identifying concussion symptoms, aswell as adjustments to the terms of contact may allow players to make more informed decisions on their conduct on the pitch.
