All contact sports come with concussion risks. However, as I have previously highlighted, combat sports do not come with a disproportionate risk of injury or concussion when compared to other contact sports.
Adding to the scientific data behind this, the American Medical Society for Sports Medicine has recently published an article in the British Journal of Sports Medicine finding “the majority of concussions occurring in organised sports in the USA are sustained in football, wrestling, girls’ soccer, boys’soccer and girls’ basketball.”
You can find the article here which is worth reviewing to help gain informed views when addressing the issue of mixed martial arts regulation particularly when the analysis shifts to injury risk.
