The problem of the use of banned substances (doping) in sport has been, is and will be an ongoing problem that undermines the very spirit of sport, beauty and pleasure, and very often the health of athletes. Therefore, it is essential to solve this problem, if possible, permanently, although it is sometimes simply impossible to do. It is this research that is designed to gain a real insight, express attitudes and perceptions of students on the use of doping in sport that is the information on this sports phenomenon of the modern age. The study included a total of 141 high school students (Gymnasium and Touristic technicians) from Pale, male, aged 15-19 +/- 0.5 years. The main objective of the study was to test the level of knowledge and identify students' attitudes about the use of prohibited substances in sport. To collect the necessary information has been used an anonymous questionnaire with 13 clearly defined questions (11 closed questions and two open-ended questions) that are related to specific knowledge, attitudes about doping in sport. The obtained results are relevant to the global indicator of awareness, knowledge and attitudes of the population of high school students about the problem of today's modern sport which is called doping. As many as 75% of the students the athletics, cycling and sports games marked as sports that are most marked by doping scandals, and 56% were tennis, golf games stated as a sport with the least number of doping scandals.

Coordination plays an important role in solving complex physical activities which arise during a biathlon race. We determined the level of coordination skills by measuring the time of a simple reaction to visual stimulus at rest by measuring the time response of complex reaction to visual stimuli by measuring the effect of visual-motor coordination (part of orientation skills - test Piórkowski) and by measuring the effect of visual-motor coordination (part of orientation skills - test Krzyżowy). In addition, we conducted a test of the simple and complex reaction after a short-term and long-term exercise. Among the tested sportswomen, the best results, both at rest and after exercise, have achieved twos Slovak athletes. Both results were above-average and slightly above-average. In order to develop physical coordination, we recommend biathletes to execute: the already known workout in different environmental conditions, while practicing new coordination exercises especially systematics not focusing on their maximum improvement but to gain general skills for practice while implementing them in the first part of the training.

Motor skills are an essential segment of the anthropological premises of man and are often the subject of scientific research. Due to their complex structure is very often in studies of this segment have a different approach in defining a model that will serve as the basis for the selection and definition of manifest variables. Usually there is a phenomenological approach, but not rare studies that are based on a functional model of motor skills. This paper analyzes the area of motor skills of the population of students and athletes, youth ages with the aim of determining the difference in the space of the mechanism of central regulation. The study included 90 students who were involved in various sports teams and 90 athletes from four athletic club. Measured is 12 manifest variables from the space motor mechanism of central regulation. In analyzing the data, using t-test and canonical discriminant analysis were obtained statistically significant results (p

The sample consisted of 40 female participants extracted from a population of elementary school students from Niš, age 12 ± 6 months, who regularly participated in their physical education classes. The basic aim of the research was to determine the influence of programmed contents of regular physical education classes on the development of the motor agility and functional abilities of the participants. The research problem was the evaluation of whether under the influence of physical education in the curriculum we can achieve a statistically significant increase in the level of the motor agility and functional abilities of the participants. By using the student t-test for small dependent samples and the canonical discriminant analysis, we determined that under the influence of physical exercise, at the end of a three-month period of physical education classes, a statistically significant increase in the level of motor agility and functional abilities of the participants was determined.

The research was carried out on a sample of 55 female high school students from Niš, 15 years of age (± 6 months). The aim of the research was to determine the canonical correlations between morphological dimensions, on the one hand, and tests for the evaluation of repetitive strength on the other, among the female students. The problem of this research was the evaluation of the influence of morphological dimensions on the achieved results for repetitive strength. 10 anthropometric measurements of morphological characteristics were used, which define longitudinal dimensionality and dimensionality of the skeleton, transversal dimensionality of the skeleton and circular dimensionality and body mass. Repetitive strength was evaluated by means of three tests. The results of the canonical correlation analysis have shown that a significant canonical factor can be found between the morphological dimensions (as the predictor system) and explosive strength (as the criterion system), along with a high corre analysis.
