Summary of Page 1:
There is insufficient information about triple jump technique in German athletics text books. This leads to experimentation and uncertainty of the performance when the skill isn’t developed.
The author used to overemphasize squats for strength development, which blocked the continuous development of his jumping skills. When one wants to “feel” the power in the jump, one is already jumping incorrectly. From all that strength increase, the short and slower approach jumps get better and better, and closer to the competition distances, because the smaller speed allows for more tension and results in more time for force application. This manner is a dead end and inevitably leads to frustration.
With that knowledge in 1977 the author began his coaching practice with the development of a “sweeping”, speed-oriented triple jump technique with wide swinging motions. In order to illustrate this technique, the author had to divide it in 47 points. Some of the points are almost impossible to achieve, but still stand as cues, goals for the athlete to strive for. Eg. point 3, an increase of stride frequency without loss of stride length is impossible, however that is what the jumper should try to achieve, in order to avoid frequency increase for the sake of horizontal speed. Also, a horizontal thigh during the support phase in the step take-off cannot be realized, in contrast to points 12 (hop take off support) and 43 (jump take-off support), however should be attempted in order to increase the speed of the forward motion of the swing leg. Some of the phases require very good flexibility, eg. the leg separation in point 18 is almost a split. In point 32 the lack of hip stretch and the sticking out of the butt is a flexibility issue.
Often a mistake in one phase has its root in a mistake in a previous one. The knee-flexion of the step-swing leg in point 31, which is the weak technique, is to be traced in an excessively high heel recovery of the swing leg during the step take-off, and usually results in planting the leg (at that moment jump-take-off leg) in the direction of the jump (sounds backwards in German,
he means the foot is traveling down and forward and braking instead of down and backwards and pawing), illustrated in the weak technique of point 33, or at least in the average technique, passive landing.
I’ll translate the first 10 points later or tomorrow.
