A recent study at the University of Nebraska reports the brain hippocampus which transfers short term memory to long term memory found football players without history of concussions the hippocampus was 5/6 (84%) of normal size and those with concussion history 3/4 (75%) normal size, their conclusion “OVER TIME the SMALLER KNOCKS still ADD UP” (59). However these findings did not show that these brain changes are linked to impaired thinking or memory skills (61).
Sub-concussive impacts are repetitive but less forceful impacts to the head are now a concern at all levels of football (51, 52, 53). In addition it is well documented; linemen receive more Sub-Concussive blows than any other position (1, 2).
Research reports contracting the neck muscles prior to impact has the greatest influence on reducing rotational acceleration because it effectively couples the head with the torso meaning in order to move the head the whole torso would have to move as well (24, 25). Research also suggests a stiff or tensed neck can reduce the probably by 25-30% sustaining mild TBI compared to a loose or neutral neck (31).
According to Dr. Stefan Duma Virginia Tech 5 Star Helmet Testing “…sports should teach players better technique so that they can reduce the number of head injuries” (60). Learn more about stabilizing the head and neck from Dr. Donald Chu PhD, PT, ATC, CSCS.

Head Up – Eyes Up – HULK UP!
DISCLAIMER
The Football Safety Academy acknowledges the coach has the responsibility to decide which football techniques should be taught for the well being and safety of his players and there is not one specific technique including the Hulk Shrug Technique or safety device that can completely eliminate the risk of injury from impacts related to football including catastrophic injury and death. To the knowledge of the Football Safety Academy no specific research has been done regarding the Hulk Shrug Technique, however the Football Safety Academy is actively pursuing this goal.
