Yes, jumpers generally have far lower sprint volumes than sprinters but, often, program reliance is based on analyses done many years ago overstating the contribution at the ankle vs the hip (I was exposed to alot of this discussion in 1981 at the European coaches conference in Venice).
The analysis of Ben in 1987 showed 3500 watts at the hip va 500 watts at the ankle at top speed.
This difference might be explained as hip dominance increasing as speed improves and no-one tested by 1981 had run close to Ben’s velocity. That said, my own experience across a spectrum of performance levels still finds isolated ankle work unnecessary.
