Jump mats

mine doesn't seem to be off that much, maybe 2" or so, but look at this one (check the jumps on vid, they look so low, crazy inaccurate jump mat or lying about the numbers for some weird reason, either way doesn't matter, just funny to see a 12 inch 23.1" jump):

yea lol that's way off. Top of my knee is about 20", she is getting shin level lulz.

Also, the way they show you shouldn't jump is what Yang's 40" looked like...

I think they're useless because it's difficult to jump to your maximum in a way that will be accurate.

Based on the results of this study, it can be concluded that CMJ and SJ, measured by means of contact mat and digital timer, are the most reliable and valid field tests for the estimation of explosive power of the lower limbs in physically active men.

i remember hitting like 123-124" on vertec at the time, which would be 27-28" based on 96" reach, but i was getting 30" on the dot on the jumpmat.. i put a 30" stool next to me and compared the jumps, directly in line, and they looked about even.. so ya maybe a good jumpmat is more accurate.. jump and reach has it's issues, it actually takes some timing and you can get all thrown off reaching up.

the most accurate jump testing would be head-height testing or high fps video testing imo.

Adarqu, I always thought VERTEC testing is rather accurate if done correctly. What problems do you see with it?

nah i'm all for vertec testing.. i'm just saying, it has some potential problems in how you swipe for the sticks, when you're at max height.. also stretching out while tilting all weird could skew the results slightly.. these are just +- 1-2" problems though, nothing major.
