Not sure if that is sarcasm, but for what its worth, ~80% of the population has the functional version of the ACTN3 gene. It really doesn’t mean much at all. I have worked on some studies with the gene and there is not much there at all. The media blowing things out of proportion…
Yes, he is a physical beast. A few weeks ago he made 345lb/157kg x 7 in the bench press. Previous best 1RM is 405lb/185kg. His bodyweight is about 223lb/101kg.
His power index is 96.78 which, along with another WR of mine and only with respect to the explosive strength of the hip/knee extensors, places them amongst the elite of the elite at the Olympic throwing level.
Why use vertical jump as that definition when likely neither group is training for vertical jump and the level of power output is significantly lower than in a medicine ball throw (or other type of throw), olympic lift, etc.?
Any index may be created, via the appropriate calculations, for a targeted application.
This particular power index has been accepted in T&F throwing circles for sometime and, as a result, I find it useful for comparing the physical preparation of my athletes to that of elite throwers; if only from the standpoint of their power output via hip/knee extension in the vertical plane.
