how can choce a the weight for trap bar squat jumps with athletes (aduts basketball player) with out measuring 1RM. i thought on %bw. it is for an academic peaper so it need to have a soild backgraound? any suggesion on peapers or researchars who have done something like that?
I guess you want to make sure they are doing trap bar jumps at ‘equal playing field’? Like a ‘standardized’ load for the research? Here are a few options:
1) As you suggested, use %BW
2) Use velocity to prescribe or jump height (e.g. load that yields 20cm height)
3) Rather than using absolute height, use % drop from their max jump height (e.g. load that yields a 50% drop in jump height)
4) Create a load-velocity profile, and prescribe using same percentage of F0
There are a lot of options, but none create ‘equal playing field’. You just need to pick one
