Abstract. The aim of this research is to perform a kinematic analysis
of the basket with 1/2 turn to handstand on the parallel bars, so as to create
the conditions for the successful creation of the teaching process and
the process which would help perfect the abovementioned element.
Mitja Petkovsek, a member of the Slovenian national team and one of the
most successful competitors on the parallel bars in the last two Olympic
cycles, was the one who successfully performed the swing to a handstand.
The kinematic parameters were determined by using a 3-D video system for
the APAS kinematic analysis and by using the Susanka body model (Čuk, 1996),
which takes into consideration 17 points of reference and 15 segments.
The research results have made it possible to define the kinematic exercise
model, which requires a gravitational and anti-gravitational phase, as
well as four sub-phases (upswing from a handstand, downswing to upswing,
forward swing to upswing and a swing with a 1/2 turn around the vertical
axis). A recommendation for the even more successful execution of the exercise
analyzed here is the later execution of the post-active transfer of the
swing from the feet to the body during the third sub-phase and the later
release of one bar at the beginning of the fourth sub-phase.
Key words: kinematic analysis, expert analysis, parallel
bars, Basket with 1/2 turn to handstand, gravitational phase, anti-gravitational
phase
KINEMATIČKI MODEL KOVRTLJAJA NAZAD IZ
STAVA U UPORU DO
STAVA U UPORU SA 1/2 OKRETA NA RAZBOJU BOČNO
Istraživanje je imalo za cilj da izvrši kinematičku analizu kovrtljaja
nazad iz stava u uporu do stava u uporu sa 1/2 okreta na razboju bočno,
kako bi se stvorili preduslovi za uspešno koncipiranje procesa obučavanja
i usavršavanja pomenutog elementa. Realizator uspešnog kovrtljaja do stava
u uporu bio je Mitja Petkovšek, slovenački reprezentativac i jedan od najuspešnijih
vežbača na paralelnom razboju u protekla dva olimpijska ciklusa u Svetu.
Kinematički parametari su utvrđeni upotrebom 3-D video sistema za kinematičku
analizu APAS i korišćenjem Sušankinog telesnog modela (Čuk, 1996), koji
uvažava 17 referentnih tačaka i 15 segmenata. Rezultati istraživanja omogućili
su definisanje kinematičkog modela vežbe, koji predviđa postojanje gravitacione
i antigravitacione faze i četri podfaze (odnjih iz stava u uporu, spad
do visa uznetog, prednjih u visu uznetom i uzmak sa 1/2 okreta oko uzdužne
ose tela). Preporuka za još uspešnije izvođenje analizirane vežbe je kasnija
realizacija postaktivnog prenosa zamaha sa nogu na telo u III podfazi i
kasnije napuštanje pritke jednom rukom na početku IV podfaze.
