Head Injury Criteria (HIC)
A strike with a HIC value of 250 will most likely knockout a person.
A Tito Ortiz elbow strike to the ear of the dummy caused a HIC value of 299.
A Bas Rutten left hook to the temple of the dummy caused a HIC value of 391.
How is this much power generated in a punch?
Fighters say the power comes “from the ass.” Scientists say it come from the body kinetically linking to the ground. The power starts at the ground as the power foot pushes off. The force move up the leg, through the rotating hips “the ass,” through the torso, out the arm, to the fist, and into the target.
Is it better to get hit by a slow moving big object or a fast moving small object?
The force of two huge, but slow moving, Sumo wrestlers crashing into each other was measured about half the force of small but fast moving fist striking a stationary target with a reverse punch.
