That’s close to the classic Parachute Landing Fall (PLF). And a good martial arts training teaches people how to take a fall.
For the PLF: Keep your feet and knees together, but relaxed enough so that there is already a slight bend to the knees. Bring your elbows into your chest, chin down, and bring up your arms so that the forearms block your face and your hands rest on the crown of your skull.
If your feet (toes, hopefully) touch the ground first, just crumple to one side or the other, generally in the direction that the fall is taking you. You’ve done about all you can for the force of the impact to be distributed across the body, reducing shock and any fractures you may receive. The key thing is to keep the body relaxed, if that can be managed.
True, it works best with a parachute attached to you to lessen the impact! But that’s what I’d hope to do if I feel support give way in a high place.
I was in martial arts a long time ago. Couldn’t whip a kitten anymore but last winter I went down hard off of a two foot rize onto solid ice. Old muscle memory saved the day. Hit just like I eas taught and was hardly sore the next day.
I agree martial arts training is great for avoiding and surviving falls.
basically you try to curl up and tuck in and roll in the direction of the fall. momentum taken out by your rolling. when slow enough place arms and legs out wide and slap the ground on the final -hopefully - roll.
first few lessons of judo are learning how to fall safely.
