In my judgement, the quest to determine what, at best, a specialized preparatory motion (such as a squat as the most it can do is match muscles involved and nature of contraction relative to the start and first step or two) can provide for a competitive motion (such as a sprint) is, in and of itself, a futile one.
To question “which squat is best for acceleration or jumping” is analogous to the following: a politician is preparing for a speech and he, by analogy to the squat study for purposes other than squatting, is pondering what sort of a vocal coach is best to make more powerful his vocal chords such that he can reach a higher decibel level. Meanwhile, an advisor of his (me in this example) is stating, who cares about a vocal coach and if you can hit a higher decibel level, we need to enhance your actual speech content and specific speech skills such as linguistics, speech patterns, vocabulary, self-confidence, and resolve. Great if some vocal coach’s strategies win out over others in assisting you in hitting a higher decibel level if politics don’t work out and you want to pursue concert hall singing; however, let’s focus on specific and irrefutable means of enhancing your speeches and do whatever you want for your non-specific preparation so long as it is congruent with the most important preparatory work.
Thus, if the context is accelerating faster, any discussion pertaining to subject matter other than sprint mechanics, types of sprint training, and the programming and organization of sprinting is inevitably one analogous to a cat chasing its tail.
Remember, due to individual structural tolerances and anthropometry/morphobiomechanics, different athletes/sprinters will invariably, and for the foreseeable future, always necessitate different modes of non-specific options/leg strengtheners. Thus, just ensure that specialized preparatory options are performed well and don’t spend too much time debating their selection.
