dc.description.abstractPrimarni cilj izvršenih istraživanja je bio da se ispita pouzdanost i osetljivost varijabli za direktnu procenu preciznosti i brzine šuta, kao dve važne karakteristike šuta. Sekundarni cilj ovih istraživanja je bio da se utvrdi minimalan broj ponavljanja koji je dovoljan za prihvatljivu pouzdanost podataka u protokolima za procenu preciznosti i brzine šuta. Pouzdanost varijabli za direktnu procenu preciznosti i brzine šuta u fudbalu (Eksperiment 1) U istraživanju pouzdanosti varijabli za procenu preciznosti i brzine šuta testirane su hipoteze: 1) varijable za direktnu procenu preciznosti, zasnovane na merenju standardnih grešaka, imaju umerenu pouzdanost i 2) varijable za direktnu procenu brzine šuta imaju visoku pouzdanost. U istraživanju su učestvovala 53 fudbalera, sa šireg spiska nacionalne selekcije uzrasta 12 i 13 godina. Apsolutna (AG), konstantna (KG) i varijabilna (VG) greška su korišćene za procenu sposobnosti pogađanja u metu, dok su brzina leta lopte pri maksimalnom šutu (BLLmax), brzina leta lopte pri preciznom šutiranju (BLLprec), kao i međusobni odnos ove dve varijable (BLLprec/BLLmax) korišćeni za vrednovanje brzine šuta. Rezultati pouzdanosti i minimalanog broja ponavljanja, dobijeni u ovom istraživanju, ukazali su da AG i VG mogu biti varijable korišćene u rutinskim testiranjima za procenu karakteristika šuta. Nasuprot tome, utvrđeno je da zbog izuzetno niske pouzdanosti KG nije dovoljno dobra varijabla za korišćenje u rutinskim testiranjima procene preciznosti. Kada su u pitanju varijable brzine šuta nogom BLLmax, BLLprec i BLLprec/BLLmax, one mogu biti korišćene u rutinskim testiranjima karakteristika šuta, na šta su ukazali pouzdanost rezultata i potreban minimalan broj ponavljanja. Na osnovu dobijenih rezultata može se zaključiti da su varijable za direktnu procenu preciznosti i brzine šuta evaluirane i prihvatljive za dalju primenu u istraživanjima, kao i u praksi, gde se mogu koristiti u kreiranju valjanih i efikasnih vii protokola testiranja, posebno kada se uvaže podaci o predikciji broja neophodnih ponavljanja...sr
dc.description.abstractThe primary aim of the present study was to investigate the reliability and sensitivity of variables for the direct assessment of the kicking accuracy and velocity, while the secondary aim was to determine the minimum number of repetitions that is sufficient for acceptable reliability of the applied protocols for assessing the kicking accuracy and velocity. Reliability of the variables for direct assessement of kicking performance in soccer (Study 1) In this study we tested two hypotheses: 1) the variables for the direct assessment of kicking accuracy based on the measurement of the standard errors will reveal moderate reliability, while 2) the variables for direct assessment of the kicking velocites will reveal highly reliability. The study included 53 young soccer players who were the members of the wider selection of national team aged 12 and 13 years. Absolute error (AE), variable error (VE), and constant error (CE) were evaluated as the variables of kicking accuracy, whereas the kicking velocity variables involved the maximum ball velocity (BVmax), the ball velocity during accurate kicks (BVacc) and their mutual ratio (BVacc/BVmax). Results suggested low-to-moderate reliability of the accuracy and high reliability of the velocity variables. Since the evaluated variables should have a property of face validity, the findings obtained generally suggest that AE (and perhaps VE, as the measures of kicking accuracy), and BVmax, BVacc and BVacc/BVmax (as the measures of kicking velocity) could be used for routine testing of kicking performance in soccer. Further development of the evaluated variables of kicking performance could be based on the involvement of other kicking techniques, as well as on the testing the athletes of different ages, levels of skill, or sport specialization...en
