Almost all people of "active" professions sometimes have to jump from great (or not so) heights. The down jump is one of the basic elements of such a sports trend as parkour and has a strict execution technique - if you break it regularly, you can significantly damage your knees.
Instructions
Step 1
Consider your experience. The human body gets used to jumping from a height, like any other physical activity. The numbers given below are some standard for a person without proper experience, therefore, if falling from a height of your own height does not cause you any discomfort, you can slightly increase the proposed values, orient them for yourself.
Step 2
Damp the load. If you are jumping perpendicular to the ground (i.e., without a run, from the edge of a hill), then your goal is to extinguish the force of gravity. To slightly reduce the height of the jump, go to the edge and take a full squat, then lightly push forward and jump off. In the jump, stretch out again to full height and (most importantly) pull the toe down. Never land on a full foot (ideally, the heel does not touch the ground at all), otherwise all the inertia of the fall will go to the spine. Land on your toes and bend your knees until the pressure from the fall is completely extinguished - at the right moment you can touch the ground with your hands, transferring some of the load there. The key to damping is that you shouldn't just bend your legs limply - tighten your muscles, as if opposing the force that "pushes" you to the floor. Thus, in the end you will look like a spring compressing under a certain force.
Step 3
If there is some acceleration in the length, go into a roll. If you jump off to a run, then it will not be possible to simply amortize, since you will continue to be carried forward. After touching the ground, you will feel two "forces": one will pull you down, the second forward. To compensate for the pressure, you need to continue to move wherever you are, and the most convenient way will be a somersault. Having touched the ground, you will extinguish some of the inertia due to the squat, but "sink" even lower - literally on your back. In this case, the vector directed forward will give you an impulse so as not to fall, namely to somersault. At the same time, a somersault is used military, over the shoulder, but not acrobatic.
