Ok folks a little bit of kitchen physics here
Not sure this is right but if someone can explain all the facts another way or knows more about physics feel free to correct me as I am unskilled in this field
Now if you drop a human from 8 feet they will normally break
unless they manage to disipate the force somehow
Free runners absorb the shock with a mixture of muscle and rolling
Judo etc absord the shock by spreading the load over the whole body as they fall (thereby minimising the impact to any one area
The stilts do something similar by absorbing the energy and decelerating us using the spring
So working on this we are hitting the floor with a maximum force of the amount that it takes to bottom the spring
This isn't the weight the spring is rated at it is the full weight it takes to compress it
I have a machine that compresses the spring by about one third and that takes a 114 kg spring up to 130/140 kg
So working on the basis that it trebles I would say the max weight for a bocker hitting the ground would be around 300/400 kg
This is not bourn out by a simple test though
If I loaded 400 kg onto the area of a set of hoofs it would sink into my lawn a fair way
But I can bounce on my lawn to the point of bottoming out and not leave massive holes a foot deep
So if anyone wants to get an exact weight for the landing bocker I have an experiment you can conduct
Get one good heavy bocker and get him to bounce to the point of bottoming on and area of grass
Measure a quantity of the hoof marks to get an average depth that they have sunk into the lawn (this has to be a fairly large quantity to allow for the difference of local hardness of the ground)
Next bolt a pair of hoofs to the bottom of a platform that you can stand on and make sure they stand out more than the average depth you got in the last bit (use packers ect)
Now stand on said platform and check the depth of the impresion
Next add a mate on your back or fill your pockets with weights and repeat
You get the idea
When you manage to make hoofmarks the same depth as the control average weigh all the people/weights and that will be the max weight you will be putting on the gym floor
Right I don't have the time to do this so who is gonna volunteer
