For Athletes Increasing neck muscle strength reduces concussions. (Neckpill)

[Deleted member 10524]

"Neck muscle strengthening has been recommended by the National Athletic Trainers’ Association as a means of decreasing neck fatigue, thereby allowing for maintenance of the head-up position associated with proper tackling technique and decreasing the risk of burners and stingers. 72 Furthermore, weak neck musculature has been proposed as a risk factor for concussion. 107 – 109 Acceleration of a struck object is inversely proportional to its mass. Because concussion results from a rotational acceleration of the brain, it has been suggested that increasing the effective mass of the head might result in a decreased acceleration of the brain after impact. The head becomes more firmly bonded to the rest of the body when the neck muscles are contracted, thereby increasing the effective mass of the head and decreasing the resultant acceleration after impact. 109 This increase in effective mass is thought to explain the decreased risk of concussion when collisions are anticipated. 108 , 109 Thus, by increasing cervical muscle strength, athletes might decrease their risk of concussion. 108 , 110 Preliminary evidence supports this hypothesis. 111 Other preliminary studies suggest that it may be cervical stiffness, as opposed to strength alone, that is associated with risk of injury. 112"
