Strength, Power, Reactivity, & Speed Discussion / About the hangtime based vertical jump calculators
« on: December 22, 2009, 02:05:48 pm »
Being an engineer i know well that the hangtime-vert calculation formula is 100% accurate, i even have my own excel version with the local gravity acceleration in the formula.
I was thinking:
The correct way to measure hangtime is to measure the time that the feet are in the air , from the first 'airborn' frame to the first 'touchdown frame'.
But doesnt that mean that we have a different measurement here compared to the normal one ( highest touch minus flat-footed reach )?
Instead of flat footed standing reach we are using 'toes-up' reach!
That would make the vertical measurements different by an amount equal to the flat-footed vs toes-up reach difference, wich would be ~4-5''.
What is your opinion?
