BIOMECHANICAL ANALYSIS OF THE HORIZONTAL JUMPS J V R D f K ,  U. C.A.S.R.I. Biolnachanical Laboratory * Prague Czechoslovakia During tbe yean 1982 - 1987 bioaecbical research team consisting of Czechoslovakia, West Gemny and * Greece obtained f i l n  mter ia ls  fmn the last iqortant athletic copetitions of that period. Our aim i s  bioraecbanical analysis of individual athletic disciplines and the transfer of the information to the sport train*. Th target of our work i s  the analpis  of the horizontal jump biolechanical aspects of the technical exploiting of the space cimtoqraphy. One part of i t s  putting to  w is verifying of new methods in obtaining and elaborating infomtion vith the belp of coquters. Biomechanical observing of sport mtion i s  based, above a l l ,  on collective processing of great data, their valuation and transformation of the received information to a suitable form for the training process. Elaboration of horizontal jqs methods is with respxt to receiving the data in the top-level events conditions based on: - infomtion about time duration of sport mtion - gecr&trical and kinemtoqraphical characteristics of the sports actions with the respect to  higher information value of the top-level competition otservinq we used these methods: 1. space cinematography 2 .  videanalysis 1. m-up speed measures (and following velocity) aided t y  fotocells I .  valorization of Me received da:a with the ccmputers. The h s i c  method applied in a l l  the previous leasures ard ewperlwnts was the kinemtsqraphic method. We devided the long j u q  on the methodical level to Run-up, Bop, Step, Junp and Landing. Me are going to deal in viev of quantity of the exploiting materials with Pre-take-off *!a and Take oii in the long jump and with the geometric and kinentic paramters and Landing in the triple jup only. The period of 1983 - 1987 rearis the progressive trend in the development of the horizontal jups .  The developwnt of the motion abili t ies led, above a l l ,  to another prfomnce iqroving (in Ule long j u p  to 8.53 m limit and in the t r ip le  jump t s  17.50 a limit). I t  i s  p s s i i l e  to suppart by evidence to these tendencies a l j s  in the changes of sow biomechanical paramten characterizinq chmqes in the technical execution of k a r  discipline. LOK rm Pre-take off -rytha I t  i s  evijent that present athletes are able t o  achieve top-level s p r t  performce i n  long junp bath Sased on a high degree of run-up speed (for E n  10.3 - 11.2 B/S, Wmen 9.5 - 10.0 m/s) and based on a high dynaa~c powr of the run-up speed is one of the basic conditlcns for the e l i te  performance ve can not a f f i n  that ~t is * a non-subtituable condition a t  a l l .  Neither the k s t  world j w r s  are able to  realize in the correct technical bay the pre-take-off mdification until today. VIII Symposium ISBS - 73 - Prague 1990
