Danny-
As you know I train a guy and a gal for these sports and as was mentioned we work lots of acceleration development (starting as low as 10m), lots of maximal strength work (very important for overcoming your own inertia and starting well) as well short jumps and heavy multi-throws. We typically only address maxV once a week depending on where we are in the training cycle due to the fact that these athletes (especially in skeleton) will not have a long enough run-in to reach anywhere near maxV. We balance all this with general strength work and overall fitness development so that the engines don't get too big for the chasis.
