Background To study the peculiarities of changes in functional indicators and body composition parameters of mixed martial arts (MMA) athletes of strike fighting style and a number of biochemical blood indicators during two months of using different intensity training load regimes, and to determine the most informative criteria for assessing adaptive body changes in these training conditions. Methods We examined 40 MMA athletes (men) aged 20–22, who used mainly strike fighting style in their competitive activity, and divided them into 2 research groups (A and B), 20 athletes in each group. Group A athletes used medium intensity (Ra = 0.64), and group B—high intensity (Ra = 0.72) training load regime. To assess the adaptive body changes we applied methods of control testing of maximum muscle strength growth (1 RM), special training (the number of accurate kicks on the mannequin for 30 s), and bioimpedansometry. By monitoring biochemical parameters (testosterone, cortisol, creatinine, phosphorus, calcium, cholesterol, LDH) in the blood serum of athletes, we determined the peculiarities of adaptive-compensatory body reactions in response to training loads. Results The obtained results of special training increased during the study period by an average of 10.5% in group B athletes, but group A participants’ results had no significant changes compared to basal data. The largest increase in the development of maximum muscle strength growth by an average of 44.4% was recorded after 2 months of research in group B. Group B athletes also had positive changes in body fat and fat-free mass indicators during the study which were two times higher than the results of group A. The laboratory studies and correlation analysis showed informative biochemical markers (cortisol, testosterone and creatinine) for assessing the condition of athletes in both groups before using high and medium training load regimes. The biochemical markers for assessing the adaptive-compensatory reactions of athletes in response to high-intensity physical stimuli at the beginning of the study were indicators of LDH and cholesterol, and in conditions of medium intensity it was LDH, testosterone and cortisol. After 2 months of study the set of biochemical markers assessing the adaptation processes before the load completely changed only in group B athletes and consisted of LDH, phosphorus, cholesterol, and calcium. At the same time, the set of biochemical criteria for assessing adaptive-compensatory reactions after training in group B athletes was completely changed compared with the data recorded at the beginning of the study. Conclusion Defining the optimal set of criteria for assessing the adaptive-compensatory changes in MMA athletes of strike fighting style will allow in the shortest possible time to correct the parameters of the training load regime for accelerating the body functionality in the process of special power training.

The internationalisation of sport at all levels, professional mobility in continuous increase and the creation of a single labour market (the European one) require the formation of managerial skills and sports management, which will provide a reference for the specialists in the field, allowing them to become more performing and efficient. The sport needs well-motivated managers and administrators who exert their authority in the spirit and the respect of new requirements, taking into account the extension of free time and the importance that citizens and the State give to a healthier way of life. Analysing the training programmes of specialists in the field of physical culture and identifying the introduction of the study discipline specific to sports management will contribute to the specialist training, improving the distribution of financial resources in sport and not least leading to a more efficient use of the human resource. Thus, during the training of physical education and sport teachers, these ones should also acquire the sports management techniques. However, current investments of public funds supporting the sport for all must be maintained, if they cannot be further developed, despite the economic recession. This idea finds its justification in the social values and benefits created by sports practices. In this context, it must be proven and argued the value of sports activities reflecting the community goals and objectives that the sport intends to serve.

Good governance in sport is an essential condition for the Olympic and sports movement in order to sustain its autonomy. Several sports organizations have established special regulations and codes of conduct, which aim to improve the self-government of sports activities. Self-regulation and good practice are essential for maintaining and developing good sports governance. However, recent surveys seem to indicate that the principles of good governance in sport introduced by the International Olympic Committee (IOC) have not yet been adequately taken into account if we refer to the standards of accountability, transparency and democracy that need to be promoted with priority. At the same time, the sports movement and the governing bodies of international sport face new challenges caused by the evolution of sport, in particular the significant growth of the commercial sector and the growing financial stake, which can create fertile ground for corrupt practices. In this context, the knowledge and correct application of the principles of good governance in sport are important factors in ensuring the efficient management of sports entities.

This article presents an analysis of the well-known specialized literature on the issue of proper coverage of the problems of the state and development of specialized general pedagogical principles used in the training process of wrestlers of various sports styles, as fundamental in the qualitative mastering of the motor-technical potential for achieving higher sports mastery. This analysis compares the substantive aspects on this issue in various sources and evaluates their significance for the practice of the training process.

The paper presents the interactive means of learning within a higher education institution of physical education and sport after a pandemic. The research group included the second-year students, in the degree program of the Faculty of Physical Education and Sport within the Ecological University of Bucharest (EUB). Taking into account the measures adopted by the National Council for Special Emergency Situations, regarding the prevention of the spread of COVID-19 (coronavirus) infection, and by the EUB Board of Directors as well, it was decided to suspend all face-to-face didactic activities and any other activities involving people agglomerations; the didactic activities will be conducted online, on the university dedicated platform, and the administrative, research and individual study activities will be continued. The research used the bibliographic study method, the questionnaire method, the conversation, the case study method, the interactive means of teaching online classes by means of zoom platform, electronic library of the faculty, YouTube web site, Google forms, WhatsApp and Facebook. The study results highlight the use of the interactive means in teaching courses online. The study focused on the practical experimentation of the questionnaire use by capitalizing on the knowledge, by expressing the motivation of the subject, the tools used and the way of completing the questionnaire. The teaching of courses online through interactive means aimed at transmitting the general theoretical knowledge and important practical-methodical examples. The online classes used the conversation with students, creating situations of collaboration and cooperation, analysis and comparison of the competitive activity and school curriculum.
