Abstract

The aim of the study is to optimise throwing distance and the size of a target as a basis for constructing a test of accuracy of a throw at a target, using a tennis ball. The optimal combination must fulfil two conditions – the tested group will achieve an average score of the count of successful hits out of all throws and using a specific combination of the throwing distance and the size of a target and it will fulfil the condition of normal distribution. The tested group consisted of 79 men and 71 women, students of the first year at the Ostrava University in Ostrava, majoring in the Physical Education and Recreation study fields. Three target sizes (0.5, 0.7 and 0.9 m) and three throwing distances (6, 10 and 14 m for men and 4, 6 and 8 m for women) were selected for both categories for the experiment, altogether nine combinations. The score of the experiment is formed by the count of successful hits of the target, out of ten throws, using each combination of the size of a target and the throwing distance. To solve the issue, the methods of testing the normal Gaussian distribution of data (Kolmogorov-Smirnov), the one way analysis of variance (Scheffe) and descriptive statistics have been used. The research confirmed that the determined conditions are fulfilled by the 10 m/0.7 m combination of the throwing distance and the size of a target for the men's category and the 6 m/0.7 m combination for the women's category.
