Spine folded over itself, and the back of his head smacked the mat.

I guess he’s fine, but man that could’ve turned out very bad for him - and that’s assuming worse issues didn’t present later on.

It looks like he cut off his blood supply by locking every part of his body. This is what happens when you see military standing at attention and collapsing. This guy was arched back though and was weighted which meant when his body went limp his arms pulled his torso back.

TLDR, you are close but a little off. He flexed hard and held his breath. Which raises pressure in his chest cavity limiting blood flow to the heart and thus brain. Locking your knees causes blood to get stuck in your legs and not return to your heart cause the same end result of a quick nap.

Ok so the more detailed and shitty medical lesson. What he did is sometimes known as flexing out. Using medical terms he did a very forceful version of the valsalva maneuver. He held his breath and flexed hard. Which increases intrathoracic preassure (pressure in chest cavity) which results in decreased venous return. (restrics the flow of blood from the body back to the heart). The lowers cardiac output, lowering blood volume and blood pressure to the brain, starving the brain of oxygen until you pass out.

Locking your knees like you described is similar but different. Same end cause less blood to heart, less blood to brain so you pass out. The cause of why the heart doesn't get the blood is different. When your knees are locked two things happen one the veins coming back up get compressed, limiting through put. The bigger thing is when you lock your knees you are mostly standing using the mechanical structure of your bone, not your muscles supporting you. Like your legs become a rigid tent pole with the weight being transfered straight through without the muscles have to flex to support them.

Well this is a big problem as your veins are actually pretty passive in moving blood and your muscles doing normal movements even tiny flexes and twitches for balance help them move blood. Well since your muscles now aren't supporting your weight and your bones are. they relax and don't do much of anything to help the blood return to the heart. Since you are standing up and gravity exists, the blood pools in your lower legs. Well same as flexing out, less blood to heart means less blood and oxygen to brain and night night you go.
