A method of collecting data was developed in order to establish the overall structure of technical-tactical elements in table tennis and to evaluate their role in basic playing systems. For this purpose, a measuring instrument (a questionnaire) was formulated in order to collect the large quantity of empirical expert knowledge of eight top class table tennis trainers. On the basis of analysis of the experts' scores, the hierarchical structure of the technical-tactical elements in table tennis was obtained, which showed that the whole group of technical-tactical elements forming the table tennis technique can be divided into three basic groups: a group of technical-tactical elements (A) used in the phase of preparing one's own and disabling the opponent's attack; a group of technical-tactical elements (B) used in the phase of attack and counterattack; and a group of technical-tactical elements (C) used in the phase of defence. The relations between the obtained groups of technical-tactical elements and their role in three basic playing systems (Attack in the table zone, Attack from a half distance, Defence) were analysed by comparing the average values of the expert's scores.

Knowing the current status of rhythmic gymnasts’ motor abilities allows a valid objective evaluation of their competitive preparedness and facilitate planning of their further development. The main objective was to determine possible differences in motor abilities of rhythmic gymnasts regarding program level they were competing in, their age and national ranking. Three groups of junior rhythmic gymnasts, competing in either A, B, or C level programs, were investigated. Both the multivariate analysis of variance and univariate analysis of variance showed statistically significant differences in the selected motor abilities regarding the program level (flexibility, strength and coordination). A-level rhythmic gymnasts scored best in all the tests assessing flexibility, coordination and strength. The differences in motor abilities between junior rhythmic gymnasts with regard to their national ranking showed no statistical significance, whereas age was statistically significant. The Pearson’s correlation coefficient revealed significant relations between certain motor abilities among rhythmic gymnasts in A, B and C level programs. The higher the level of a program, the higher the correlatives, and vice versa. Two tests had the largest contribution to the success achieved in the competition: the figure of eight with bending and forward bent on the bench. The scientific value of the proposed research is aimed at better planning, programming and control of training process in rhythmic gymnastics.

Main purpose of this work is presentation of a complex program that consists of simple program content focusing towards targeted change of important anthropological characteristics. To achieve the objective, authors created "stay at home" fi tness program with simple exercise content which is adjusted for both trainees based on their fi tness level. The sample is defi ned as a pattern of two trainees. One exerciser is male and physically inactive and the other is female and physically active. The initial and fi nal state of the subjects is determined with 4 tests for assessment of morphological characteristics and 6 tests for assessment of motor abilities. For comparison of the measured results of the initial and fi nal state of the respondents we used the method of calculating the diff erence expressed as a percentage, using the "Microsoft Excel". After completing treatment, we've observed positive changes in all measures for the assessment of anthropological status, for trained and untrained persons.
