Abstract

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 15.1 (± 0.75) years on average from a distance of 4.5 m. The values of Pearson’s correlation coefficients and multiple correlation coefficients (generally above 0.7) as well as Cronbach’s alpha coefficients (above 0.9) and Kendall’s W coefficients of concordance (mostly below 0.1) 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 0.6, we can say that only one rater did not meet the scientific evaluation criteria.
篮球跳投若干参数的信度分析
在运动训练实践中。本研究的目的是确定篮球教练是否能够通过肉眼观察来统一(一致)评估跳投的释放时间、释放角度、球的旋转和整体正确性。这项研究包括13名教练(6名经验丰富,7名经验不足)的样本,他们的任务是评估平均15.1(±0.75)岁的年轻篮球运动员在4.5米的距离内进行的篮球跳投。Pearson的相关系数和多重相关系数(通常高于0.7)以及Cronbach的α系数(高于0.9)和Kendall的W一致性系数(大多低于0.1)的值显示出在对整个镜头以及单个镜头参数的质量(正确性)的评估中的高水平的一致性和一致性。在评估单个参数的一致性时,可以建立相当低水平的一致性和一致性。这适用于经验丰富和经验不足的教练组(评分员)。结果表明,对至少六名评分者进行的评估的可靠性水平适合科学研究。考虑到ICC(类间相关性)的低值,仅等于约0.6,我们可以说只有一个评分者不符合科学评估标准。
