The following is some information that was presented on the
National Geographic television show, Fight Science: Mixed
Martial Arts, first shown on January 27, 2008. Some champion
Mixed Martial Arts cage fighting champions were tested to
determine their striking power. They struck a car crash dummy
specially set up to measure the force of their strikes. The
striking force of his reverse punch was measured at 500 pounds
per square inch (PSI), the same as for a professional boxer. His
roundhouse kick to the chest resulted in a 2.2” chest
compression on the crash test dummy. A 1” chest compression in a
car accident is considered is potentially fatal. The striking
force of his standing reverse punch was also measured at 500 PSI
The striking force of his full-mount reverse punch on the ground
was measured at 2000 PSI. The increase in force was due to his
being able to drop is body weight into the punch from his
grounded position. - Next >>
