Hello, In one of your articles: Interpreting Power-Force-Velocity Profiles for Individualized and Specific Training stated that..... "Adding the previously described vertical profiling to this horizontal profiling could help better determine whether a lower HZT-F0 is due to an overall deficit of lower-limb strength (as indicated by a low VTC-Pmax) and/or a deficit in the transfer of this strength in the specific horizontal push-off motion (technical capability)." I am having trouble understanding what is considered a low vertical maximal power output. Can you help clarify? Hope to hear from you soon, Thanks again.
Hi David, the idea is that if you know the "non-specific" F0 of the athlete (ie the F0 measured during the squat jump test profile) then you can better interpret a low sprinting F0: typically if you observe a low F0 in sprinting (say 5-6-7 N/kg depending on the sport and level/context) BUT the athlete have a good vertical F0 (say 40 N/kg or more depending on level and context) then you can interpret that as being a weakness in how this good force capability in absolute terms is transferred to sprint-specific force output. If BOTH F0s are low then you know that you'll need to work on BOTH a better maximal force capability AND a better sprint specific force output. This is one reason why even if your focus is sprint acceleration, the jump profile might be an interesting piece of info
Hi, Thanks a lot for your video! Just a quick question - When I conduct the 'solver' button, it seems that the Tau of spreadsheet changes automatically. Is it the right way to do? Thanks! Seonghwan Choi
Is it recommended to use the slow motion mode (240 fps)?

@@jbmorin3327 thank you!
Hello,
I cannot find the solver, did something in excel change to remove it?

What is the difference between "V0" and" Maxspeed"?
Max speed reached during sprint and estimated true max speed
Where do u get this spreadsheet? I just bought the app.
It is on JB's website. Search should pull it up!

An outstanding tool!
where is the link to download the tool ?
Bonjour, quel est le nom de ce joueur svp?
