Is this statement true?

I understand completely.

My suggestion to you, which is also consistent with your interests on the matter, is to incorporate the lowest ‘cost’ means into the training first and see what you get out of them.

This would include relatively low stress jump/bound variations that don’t require much preliminary preparation in contrast to, for instance, various single/alternate leg bounds for farther distances that present much greater structural stress.

If you’re not already doing them I suggest:

Double leg Horizontal single, and multiple response efforts up to 10m or so) as well as standing alternate leg triple jump (initiated via a double leg take off) for start and acceleration

Vertical multiple response jumps (ergo hurdle hops), you could experiment with efforts here up to the 10sec range, for max V.

Again, these are lower cost selections.
