I might do them as part of the warm-up of a track session, but without the hops, or at the most one hop into a throw/accell. Multiple hops might fatigue the athlete just enough not to allow them to sprint at their top speed. I suppose it would depend on the distances they’ll be running in practice. If it’s under 50-60m, then It might be fine, but top end speed work would more than likely be hindered for that session. If it is during the GPP or with a slower athlete, again, it would probably be fine.
NumberTwo, do you have a chart (similar to the motor recruitment chart) for intensity where all the typical training elements are listed? i.e., tempo and core-work at one end, and “elite-performance-top-end sprints” and Olympic Lifts at the other. Might help clear up some of the confusion about when the full 48 hours of recovery is necessary due to CNS fatigue/taxation and when and where to place/plot the different training elements in a single session. I know the information is talked about in the GPP DVD regarding a spit routine for weights early on in the GPP.
It also depends a lot on the level of the athlete. One think is regional level, another is college, another is Olympic potential, another is team sport. The higher the level, the more stringent the need for 48 hrs or more between HI elements (I would tend to put med ball throws at sufficient level there for high-level athletes).
