Fighters/Jiu jitsu STOP doing this exercise! Anatomy/evidence matters HD

A common warm up exercise is increasing your chance of knee injury Not sure why audio and video do not link up? --- Because audio is out of sync let me clear something up. Both examples of knee warm ups should be avoided. Think principles before methods. Meaning avoid any exercise that promotes knee flexibility. Example : in essentially 100% of anatomy and rehab/ injury literature the primary importance of the knee,MCL, ACL is stability ( opposite of flexibility) In essentially 100 % of injury literature the mechanism of injury of the knee including MCL and ACL injury is valgus stress and rotation ( flexibility) In essentially 100 % of peer reviewed studies of the knee,MCL and ACL valgus ( internal rotation, the exercises in video ) is described as the main mechanism of injury ( other examples being hyper extension and compression) Meaning the injury mechanism is essentially flexibility meeting force. Coaches and athletes who continue to practice this principle after being exposed to the facts are saying two things. I Anatomy does not matter Evidence does not matter. Thanks for being intellectually curious . It matters to you.
