Why does qpal sprinter start bipedally, and bipal sprinter start qpal?
Because they both need to adjust their body mass to optimal balance position before accelerating their momentum forward in a controlled fall. Both use their arms gyroscopically while moving, keeping arms still slows them down drastically.
Looks like you are on the right track [no pun intended]. Do you have a source for this besides yourself?
If not, it would seem that the human qpal start is to take advantage of starting blocks that wouldn't
be of help with a bpal start. Lots of thrust generated at the starting gun.
That reminds me: is it difficult to measure thrust directly? This is very much on topic for swimming plesiosaurs,
in its rightful place, sci.bio.paleontology. The article that you linked here in s.a.p. didn't measure
actual thrust, just measurements of various percentages that I still haven't figured out. I talked about that here:
