Who has it now?
I don`t follow the “scene” and most Germans don`t care about records but it`s not that impressive..
bear in mind that Germans have the widest shoulder`s worldwide, also the highest strength to calorie correlation and working output.
Also more muscle fibers in the Shoulder Neck area. (raw strength)
you can Google the Term “Fast twitching muscle Fibers”. (In relation to optimal oxygen saturation.)
Maybe this picture answers some of your questions. Most of it is genetics.
