how important is to test jump height of your athlete?

One of the biggest questions that all of strength and conditioning coaches are doing everyday is how our athlete is feeling. This has 2 different options, 1 how he/she feels and how acctualy feels especialy for legs. Answering the first part is only the feeling of athlete is something like Borg scale you can use. The problem is how acctualy feels and we can find this out with a simple measuremnet of jump height. I have recently discovered a very usefull app that accurate measures the jump heigth and other parametrs, So every day after the same warm up my athlete has to do 3 counter movement jumps and we hold the best of 3. Before that we must have a baseline measurement which is before games and after good rest. With this kind of measurements we can understand very quickly if we have an athlete with tired legs or with in a good condition legs and ajust training volume. Also it is very helpful to understant the effects of condinius matches to legs power and to find ways to keep a better form.

Here i have a paradigm of our last days on tour with Stefanos Sakellaridis and a table of what happened the same day.
