Top of spring bruising hamstring. Adjustments possible?

Cheers for that pic Athoul.

Looks to have about the same dimensions, even though it is sheathed.

The only thing i can think of, is that the measurement from the footplate, up the vertical support, to the tip of the upper spring mount, must be shorter on the 7's, and longer on the RiSers??

[Athoul]

From the footplate the the top of the bit of metal over the spring i measured about 39cm

Wear shoes with thick soles.  I'm 5'10" but my soles are something like an inch and a half thick, maybe a little more.  I have no trouble at all.

[Athoul]

What shoes have a sole bigger than an inch?

Have you got a picture of these groovy platform shoes you own

[zipp]

Your on my wavelength Athoul, just been out to measure mine as well.....41cm



So the 2cm difference would make all the difference. That explains why you are so comfortable, even when "checking for gum".
Looks like the 7's have better ergonomics.

Sounds like Frank is out in high heels.

[Mr Frank]

Nope, I actually measured, and they're just under an inch.  They just looked higher at first because of the way they're built.

After yesterdays 6hr usage, and some progression in my bocking, this is how my hamstrings look this morning.
They are very tender, i can tell you.



This can't be right, there must be some sort of adjustment they can design to avoid this?
From an ergonomic point of view, i have always classed myself as "Mr average", it would seem that PoweriSers are designed for the tall and lankey?

Anyone using 7's have this bruising problem?
Is it only PoweriSer users that suffer, or do different brands users suffer as well?

I am wondering if all bocks are created equal?
Is there anyone else that could measure their bocks from the footplate to the top of the upper spring mount please?

I was looking online for an "average limb measurement" table, but so far i have come up empty.
My heal to hamstring measurement is 43cm, (when at 90 degrees) so probably closer to 44-45cm with trainers on.



With my bocks measuring 41cm, that gives me a range of 3-4cm, movement which is obviously not enough.

I would be interested if others could supply measurements of bock and legs, to see if any pattern emerges.
Maybe something like this:

Type of bock=                   2008 PoweriSer
footplate to spring top=   41cm
your height=                     5'11" or 180.5cm
your heal to hamstring=   43cm

I can try and graph/chart the info and then maybe the info could be passed on the the manufactures for future development?

I find it a shame that the enjoyment i get from using the bocks, is marred by unnecessary pain.

hmm yeah this is odd, i'm 5'6" and have never really had this problem, i know the springs hit my legs if i try a checking for gum or such moves, and i do them anyway, but i've never had any brusing like that, i'll measure my legs and stilts next time i get a tape measure

Interesting that your right leg bruising is more  inside of the leg.  Maybe just the angle your standing though.

Not really of any significance to this thread though.  I'ts just interesting.

[Powergirl.]

I'm small to! I have the same problem with the spring hitting my leg, but i've never had such problems either. So far all i have is flip-flops to lift me up a bit, and like most people have said,i have added foam onto the top where it hits my leg. I am still not tall enough though, but there is less contact between my and the spring end, but if there is contact it doesn't hurt anymore. I'm still growing....(I think) so i'll just have to be patient.
Hope thoes bruises clear up soon!

You don't suppose it is anything to do with the new calf cuff design do you??

Is this model the only one to feature this?

[Big Bad Bounce Boy]

deffinatly not i have 7 t-rex an im about 6ft i think and my spring top hits me and bruises my calf anytime i bounce so i just pad it over with foam

[zipp]

BBBB,
Surely you mean hamstring, not calf?
And for it to contact you whilst just bouncing is very strange i think?

I only get hit, when bending my legs up in a jump, or standing up from the ground.

I am really not understanding this padding it with foam lark.
Surely this will make the problem worse, as it decreases the distance between the back of the leg and the spring mount, increasing the chance of impact??

Interesting to hear of another brand user getting bruises on the hamstring.

Any more of you getting bruised here?

[Athoul]

It means that instead of impacting a solid peice of metal you impact a soft bit of foam and therefore reduces the bruising
