A group of professors studying anatomy, biomechanics and organogenesis conducted a biomechanical analysis on three different sprint start patterns to decide the safest sprint position. When conducting this experiment, the professors wanted to identify which sprint start would be the safest when dealing with neck injuries and sport related concussions (Bonnechere, Beyer, Rooze, Serge Van Sint, 2014). 25 males of various heights and weights were recruited to participate in this experiment, 12 of them being football players and the other 13 being non-football playing participants. In this experiment, a stereophotogrammetric system was used to record motions and positions. Participants wore little to no clothing and were barefoot to execute the different study trials. All of the measurements made occurred inside the professors’ movement lab on a synthetic floor.

The average movements collected where then time regulated in order to compare curves for Verticality, FOV, Head Angle, Head Speed, Head Acceleration and Body Speed. (Boninechere etal, 2014). To measure the severity of possible collisions between the heads of two players facing each other, the data collected in the experiment was used in equations to correctly calculate the risk. “The head speed (in the vertical direction) is higher for the 4-point start position compared to the 3- points (difference of 0.11 m·s-1, see Table 2) and 2-point (difference of 0.60 m·s-1) because initial position of the head is lower in 4-points start” (Bonnechere, Beyer, Rooze and Serge Van Sint, 2014). Results showed that the 4- point start is the most unsafe when dealing with sports related concussions and neck injuries due to the fact that your body and head are closer to the ground, your head is also moving faster when in a 4- point
