More Tech Talk (Aug ‘05)
(originally posted 8/28/05)
The new shoes are great. They are a big improvement and should reduce all those arch support problems I was having with the old ones. They’re fast too.
I strained some muscles in my back and neck that are causing problems today, probably while practicing the weight throw. Today’s video analysis:
Hammer: Footwork more or less followed the proper pattern, but appeared pretty awkward. One-turn throw around 90ft, two-turn throws 105-110ft. All appeared to be in the sector. Bent arms are still a problem, as is rotating too far on each turn. Need to be much more aggressive on the last wind going into the first turn. Need to develop much more initial ball speed, similar to what I’ve done in the weight throw.
Shot Put: Block looks much better, but right leg kicks out too high. This causes a long pause in the center as I wait for it to plant before I begin to drive from the power position. I may need to copy Timmerman’s somewhat sideways leg kick…it seems to stay lower that way. I need to make sure that it doesn’t result in a premature unwinding of the upper body though. All throws in the 34-35ft range.
Discus: Over-rotation was much less, but still there. Need to pick up left leg earlier. Blocking leg lands way too far forward in the circle. This long step to the front at the end of the throw takes too much time, during which upper body torque is lost. The long step to the front appears to be caused by CG shifting forward during the second single-support phase, and the need to step forward to catch myself. With the CG so far forward by the time the front foot touches down there is very little room left to drive into the block. A slightly greater backward lean during the flight phase that is more in line with the leg of the “7” (video shows near vertical now, and in line with the direction of throw) should help the CG to remain over the pivot foot, and a conscious effort to keep the blocking leg close-in should help maintain rotation and keep the block less extended.
Javelin: I’ve got a long way to go here. Coming over the top a little better, but blocking leg still collapses, and back is not arched. Trajectory was ok but distances remain unchanged.
Weight Throw: Need to remain smooth, on balance, and relaxed. Weight slipped out early once causing a low throw, and late once causing a high throw. New beginning “wind” is still working but I need to make it a slow, long movement. Two-turn throw made 40ft.
