摘要:The ability to visually perceive the movement of athletes or objects they handle is an important skill in sport training practice The aim of this study was to establish whether basketball coaches are capable of uniformly (congruently) evaluating the release time, release angle, ball rotation and overall correctness of a jump shot by observing it with the naked eye The study included a sample of 13 coaches (six with more and seven with less experience) whose task was to evaluate basketball jump shots made by young basketball players aged 151 (± 075) years on average from a distance of 45 m The values of Pearson’s correlation coefficients and multiple correlation coefficients (generally above 07) as well as Cronbach’s alpha coefficients (above 09) and Kendall’s W coefficients of concordance (mostly below 01) show a high level of uniformity and congruence in the evaluations of the quality (correctness) of a shots as a whole and also individual shot parameters Quite a lower level of uniformity and congruence can be established in the evaluations of the consistency of individual parameters This applies to both groups of more experienced and less experienced coaches (raters) The results allowed an assessment that the levels of reliability of the evaluation of the group of at least six raters are appropriate for scientific research Given the low values of the ICC (Inter Class Correlations), only equalling about 06, we can say that only one rater did not meet the scientific evaluation criteria.
其他摘要:Vizualno zaznavanje gibanj športnikov ali predmetov s katerimi le-ti upravljajo je ena od pomembnih veščin v praksi športnega treniranja V pričujoči raziskavi nas je zanimalo ali so košarkarski trenerji sposobni na osnovi opazovanja meta s prostim očesom enotno (skladno) oceniti izmetni čas, izmetni kot, rotacijo žoge in pravilnost meta v celoti V raziskavi je sodelovalo 13 trenerjev (6 bolj izkušenih in 7 manj izkušenih), ki so ocenjevali mete iz skoka z razdalje 45 m, ki so jih izvajali mladi košarkarji stari v povprečju 15,1 (±0,75) let Vrednosti Personovih korelacijskih koeficientov in koeficientov multiple korelacije (praviloma nad 07) ter vrednosti koeficientov Cronbach\'s alpha (nad 09) in Kendallovih koeficientov konkordance W (praviloma pod 01) kažejo na visoko stopnjo enotnosti in skladnosti v ocenjevanju kakovosti (pravilnosti) meta v celoti in tudi posameznih parametrov meta Precej manjšo stopnjo enotnosti in skladnosti lahko ugotovimo pri ocenjevanju doslednosti (konsistenčnosti) posameznih parametrov To velja tako za skupino bolj izkušenih, kot tudi za manj izkušene trenerje (ocenjevalce) Na osnovi rezultatov ocenjujemo, da so stopnje zanesljivosti ocenjevanja skupine najmanj šestih ocenjevelcev ustrezne za znanstveno proučevanje Glede na nizke vrednosti ICC (Inter Class Correlations), ki znašajo samo okoli 06, lahko rečemo, da en sam ocenjevalec ne zadošča kriterijem znanstvenega ocenjevanja.
