How come MANY coaches talk of depth jump vert vs standing vert and that if your depth jump is NOT higher than you lack reactivity? I have read this many times. Are these guys crazy ? I honestly want to figure this out, not trying to argue with you....
This is from Kelly Baggett -
"If your best vertical jump from a regular standing position is better then your best depth jump from even a very low box height (~ 8 inches) then you should use landings via drop jumps to increase your ability to gather energy and optimize force absorption capabilities. If your depth jumps are higher then your regular standing vertical jump then you are a good candidate for depth jumps. "
Again from Bagget -
Those who are faster than they are strong will tend to have many of the following characteristics:
E: Your bounce depth jump (from a box height of 12-18 inches or more) will be higher than your best standing verical jump.
Again - If plyometrics are already part of your training, use a box that results in your highest vertical. For example, if you can jump 30″ from a 12″ box, 32″ from a 18″ box, but only 31″ from a 24″ box. Use an 18″ box.
Those are just a few examples. I know that I have heard Defranco talk about assessing reactivity using depth jumps in the same manner but I can't find the info.
