The motor quality of speed is defined by some authors as conservative related to its impact which involves the use of specific means and methods to influence its development. The selection of such means and methods depends on the age peculiarities performance which is mainly a consequence of its genetic predetermination. The main factor for exerting effective influence on the development of speed in school age is defining the age peculiarity impact of the quality and the specific changes in the growth in age aspect. Based on the above-mentioned facts, the aim of the current study is to trace the changes and their impact on the speed quality with schoolboys via a 30-metre-race test. In order to achieve the aim, we set the following tasks: 1. Reading about the problem in scientific sources. 2. Processing the results of the 30-metre-race test of the boys whose personal data were taken for the research project, performed in 2018. 3. Revealing the impact peculiarities of the speed quality with schoolboys in the aspect of age. We fulfilled our study tasks by statistic processing the achievements of the boys aged 6-18 from 28 schools in 22 towns in the country, having participated in the 30-metre-race test. We applied a variation and comparative analysis which allowed us to specify the impact peculiarities of the motor quality in its age aspect. After processing and analyzing the results of the study we found a lot of changes in the speed performance with schoolboys. These changes showed different periods of intense development of the quality, based on the increased results among the different ages. On the grounds of the above-mentioned results we recommend the use of specific means and methods to improve the effect on speed in school age.

Match fixing on worldwide scale today is a business and a matter of profit. In this connection, the purpose of our study is to find out if there are national normative measures in place to prevent the Game fixing. The main method used in the development of the report is the study and analysis of literary sources. The results of the conducted study on the basic normative documents and regulations of the Bulgarian Football Union show the presence of a number of measures with a preventive character, which are aimed at the prevention of game fixing. Conclusions: 1. Legislative texts with subsequent sanctions are provided in the Republic of Bulgaria to prevent the fixing of football matches. 2. The Chapter of the Penal Code of 2011 includes Chapter VIII A, which is "Crimes Against Sport", and in a proven case of fixing of a sporting event, provides for a sanction of one to six years' imprisonment and a fine of one thousand to ten thousand BGN. 3.

Tracking the changes and peculiarities in the manifestation of motor abilities in school age is one of the prerequisites that determine the effectiveness of the learning process. Effective learning, in turn, is a leading goal of modern education. In this sense, tracking and identifying peculiarities and changes in the manifestation of motor abilities is an enduring issue in the theory and practice of physical education. On the basis of the above, we set as the aim of the present study to identify the peculiarities in the manifestation of the motor ability speed in pupils at the lower secondary stage of primary education. In order to achieve this aim, we set ourselves the following tasks: 1. Reading about the problem in scientific sources. 2. Processing the results of the 30-meter-race test of the boys. 3. Revealing the impact peculiarities of the speed performance of schoolboys in the aspect of age. We fulfilled our study tasks by processing the achievements of the boys aged 10 - 14, who participated in the 30-meter-race test. We applied a variance and comparative statistical analysis which allowed us to specify the impact peculiarities of the motor ability in its age aspect. After processing and analyzing the results of the study, we found a lot of changes in the speed performance of 10-14 years old schoolboys. In this regard, it is significant to note the changes recorded within one school year, which had the appropriate level of reliability to allow us to formulate recommendations for the work of teachers of „Physical Education and Sport“.

One aspect of the security of sport, which is rarely considered by the organizers of sports events, concerns the different manifestations of match-fixing. The match-fixing of the result of a sports event or any component of it contradicts the established norms and values of the sporting competition, drawn up at the end of the XIX century by Baron Pierre de Coubertin and known as Olympism. Today, match-fixing is one of the phenomena in modern sport. Advertising, publicity, profit largely regulate relations in professional sport, and in full force, this applies to football as the most popular sport in the world. If we look at what has been said so far through the prism of Bulgarian football, it is enough to look at the Bulgarian football championships, whose official sponsor is an online betting company at sporting events and the first football league is named after this company. This same company has sponsorship relations with more than 10 football clubs, and to them we can add the volleyball and basketball federations, as well as some of the brightest representatives of these federations. Noticing this trend of business entering the sport, we set out to explore the opinion of players and their coaches about the manifestation of the phenomenon of match-fixing in Bulgarian football. The results of the survey show the existence of match-fixing at both professional and amateur level and allow us to indicate some steps to prevent such non-sporting techniques from winning.

Studying motor qualities and their different performance aspects is one of the main goals of experts in physical education and sport. Determining the peculiarities of motor qualities performance, especially speed is the result of numerous tests which reveal lowered levels of both motor and physical activity of children. Taking into account the fact that the quality of speed is one of the basic goals in teaching physical education and sport at school, studying its changes along with the age development of the students is fundamental for the selection of methods and resources for its purposefully development during the lessons. Based on the above-mentioned facts, the aim of the current study is to trace the changes and their impact on the speed quality with schoolgirls via a 30-metre-race test. In order to achieve the aim, we set the following tasks: 1. Reading about the problem in scientific sources. 2. Processing the results of the 30-metre-race test of the girls whose personal data were taken for the research project, performed in 2018. 3. Revealing the impact peculiarities of the speed quality with schoolgirls in the aspect of age. We fulfilled our study tasks by statistic processing the achievements of the girls aged 6-18 from 28 schools in 22 towns in the country, having participated in the 30-metre-race test. We applied a variation and comparative analysis which allowed us to specify the impact peculiarities of the motor quality in its age aspect. After processing and analysing the results of the study we found a lot of changes in the speed performance with schoolgirls. These changes showed different periods of intense development of the quality, based on the increased results among the different ages. On the grounds of the above-mentioned results we recommend the use of specific means and methods to improve the effect on speed in school age.
