I think Olympic lifts can transfer in many ways and I elucidated only a few of them. I do not pigeonhole the olympic lifts and derivatives or even strength training in general to improvements in initial acceleration since many coaches and elite athletes have noted the improvements in the middle and later stages of the race through lifting, along with some theoretical models for how this could happen. If this was the case (lifts only influenced the first 10-15m), I don’t know why anybody other than 60/100m sprinters would want to utilize lifting at all or how it could have any significant influence.
I think sticking to Q&A only works when you have legitimate answers. Simply saying other methods always transfer over better, without any empirical basis and lots of evidence and experiences stating otherwise, is pretty insane.
I don’t think any specific exercise (other than the competitive activity) is absolutely necessary 100% of the time, but I do think there are exercises that tend to help more than others and there is a significant empirical basis with which to derive that from. Ignoring the mounds of evidence or simply writing it off as “inefficient at best” is a good way to not maximize results.
