Tonight at UFC 228 Zabit Magomedsharipov defeated his opponent, Brandon Davis, with an unorthodox leg lock/hamstring stretch which is known as the ‘Suloev Stretch’
Dr Kickass, Mike Piekarski, a Doctor of Physical Therapy, Former MMA Fighter, Brazilian Jiu Jitsu black belt. (Follow him on instagram) explains the mechanics of this move and was it a kneebar, banana split or hamstring crank?
“Traditional kneebars work by isolating the femur to create excessive hyperextension to challenge the knee ligaments. However Zabit was not able to isolate the femur based on his entry into the leglock. Without isolation he likely was not able to create sufficient torque on the knee ligaments to break them.
If it was not a kneebar than why did his opponent tap?
The hamstring group is made up of 3 muscles:
These 3 muscles are maximally stretched with terminal knee extension and significant hip flexion, which mimics this position. Typical hamstring length when the knee is straight is 70-90 degrees and in this position his shin was touching his collarbone, almost 160 degrees❗️
In my professional opinion I would imagine Davis suffered a hamstring strain/ tear that elicited a tap.”
