I will just answer where I believe I have enough knowledge to answer.
I believe that short approach jumps (<10 steps) can fall into the low cns category. The target of those is to work on technique and can be done on the tempo days.
Full Jumps -
Very high CNS ‘height’.
Not used very often and usually saved for competition although I have heard the Cubans use a large amount in training at times. Maybe used before tapers for a final HI stimulus?
The cubans are crazy. I see their training regime live in a daily basis and if you survive it you are superman. So I would take anything from them with a grain of salt.
Speed and Special Endurance-
The role of SE in jumping has always confused me. Obviously you need to survive 6 full jumps… but recoveries are so long it hardly qualifies as endurance. Jumpers often compete in a few 100m races though, so some SE seems necessary. Charlie has stated that SE seems to regulate weight and make athletes muscles ‘denser’ which would benefit the jumps.
Are longer SE reps necessary for jumpers? Or would split runs suffice?
I personally believe that for a jumper, besides the physiological effect of SE, long high speed repeats are needed for the rythm feeling that is also needed in the run up. During a SE session you have more time to be aware of your posture, relaxation, etc.
Plyometrics -
Jumpers typically have high plyometric volumes. Considering the volume of short approach jumps, how much higher should the volume of additional plyo’s be than that of a sprinter? In addition, the type of plyo’s used include lots of single foot contacts, much longer distances covered, and running approaches. All inducing a lot of muscle and CNS stress.
I use plyos scattered all week long. Before a speed session right now I am doing 5 x LRLR+j. As a jumper I believe quality is extremely important and I believe that you have to be fresh for such a bounding session.
Abs -
The use of strength in addition to CF high rep work on the abs has been discussed recently. Is this strength requirement accentuated in the jumps? Considering the take-off forces and powerful leg shoots used?
I don’t believe is necessary. A powerful leg shoot is result of correct use of your legs, you don’t need crazy abs to do it, you just have to learn to “pendulate” your legs the correct way.
