My understanding is that though it is a drill for developing maximal speed, you won’t probably achieve a maximal speed within the drill itself especially not EFE. You would be able to come closer to maximal velocity on the second F of FEF if you did not slow down much in the E (according to CF) but even if the first E of EFE was a maximal effort (which it is not) there is simply not enough distance 20m or speed from which to hit maximal vel. within the F of EFE unless you were accelerating throughout the 20m F phase which I don’t believe is the way it is to be executed-I was under the impression that the velocity within F stays fairly constant.
I am also under the impression that the value of the drill is:
- To achieve relatively high velocities and changes in speed without the overuse of multiple straight maximal efforts. That is, too many consecutive maximal efforts with 40-60m accelerations that achieve approx. the same velocities (or whatever distance is necessary for an individual to hit maximal velocity) will create the unwanted dynamic stereotype or speed barrier too soon in a speed development program. Higher velocities could be achieved eventually (theoretically) with the inclusion of broken runs/speed changes drills (ins/outs), sprint float sprint, along with accelerations, and fly-ins.
2)The use of the speed change drills to promote complete relaxation by promoting a smooth speed change which, in part, can be done because the velocities achieved are going to be sub-maximal especially with EFE.
Wasn’t there a quote (I cannot find old threads even when searching archives) where CF said that the speed achieved on the F of EFE was similar to velocity you hit at 10m of a 100m race?
