Tennis is very popular, but the incorrect action produces sports injuries. The knowledge of sports biomechanics is used in sports injury research on tennis. Two mainly classical research methods on tennis sports biomechanics are theoretical research and experimental study. This paper introduces the technical features of two research methods, theoretical research is mainly based on the model. The experimental study is mainly based on three systems of the kinematics, dynamics and biological measurement. The differences among them are compared in order to provide the overall ideas for study on sports injury of tennis.

BackgroundTime-to-event modelling is underutilised in sports injury research. Still, sports injury researchers have been encouraged to consider time-to-event analyses as a powerful alternative to other statistical methods. Therefore, it is important to shed light on statistical approaches suitable for analysing training load related key-questions within the sports injury domain.ContentIn the present article, we illuminate: (i) the possibilities of including time-varying outcomes in time-to-event analyses, (ii) how to deal with a situation where different types of sports injuries are included in the analyses (ie, competing risks), and (iii) how to deal with the situation where multiple subsequent injuries occur in the same athlete.ConclusionTime-to-event analyses can handle time-varying outcomes, competing risk and multiple subsequent injuries. Although powerful, time-to-event has important requirements: researchers are encouraged to carefully consider prior to any data collection that five injuries per exposure state or transition is needed to avoid conducting statistical analyses on time-to-event data leading to biased results. This requirement becomes particularly difficult to accommodate when a stratified analysis is required as the number of variables increases exponentially for each additional strata included. In future sports injury research, we need stratified analyses if the target of our research is to respond to the question: ‘how much change in training load is too much before injury is sustained, among athletes with different characteristics?’ Responding to this question using multiple time-varying exposures (and outcomes) requires millions of injuries. This should not be a barrier for future research, but collaborations across borders to collecting the amount of data needed seems to be an important step forward.

Changing the system of family values, views of the society on the significance and functioning of the family institution contribute to the transformation of marital role relationships in modern families. The already formed model of role interaction, the ability of spouses to define and clearly distribute family roles and to treat them responsibly is the important factors in building constructive marital relations and creating a favorable psychological climate in the family. Objective. The research deals with the analysis of the essence of the “family role” concept and the classification of family roles; experimental definition and analysis of the main types of family roles in marital relations. Methods. Theoretical research methods were used to solve the research problem: analysis of scientific psychological literature, generalization method, systematization of scientific information. To solve the second part of the set objective, the empirical research methods were used, such as: conversation, psychodiagnostic method “Distribution of roles in the family” by Yu.Ye. Alioshyna, L.Ya. Hofman, O.M. Dubrovska, and also the method of processing and quantitative and qualitative interpretation of results. The research was conducted during September-October 2020. The study involved 11 married couples (husband and wife) with different marital experience of 22 people aged 25 to 47 years (Kyiv). All the couples have children aged 1 to 20 years. The results of an empirical study of the peculiarities of family roles distribution showed that the roles of entertainment organizer (63.64 %), master (mistress), (72.73 % and 63.64 %), the family subculture organizer (54, 55 % and 45.45 %) women and men share almost equally; the roles of educator and “psychotherapist” is more typical for women (90.91 % and 81.82 %); The role of sexual partner and the partner responsible for material support is more often performed by men (90.91 % and 72.73 %). The prospects for further research are seen in the study of role interaction in the parental families of adolescents and young people as a prerequisite for their future family roles.

The aim of the study is to examine the effects of sports injuries experienced by adolescent athletes between the ages of 13 and 18 on their quality of life during training and competition. The universe of the study consists of licensed athletes between the ages of 13-18 who play sports at the Manisa Youth and Sports Provincial Directorate. In the study, purposeful sampling method was chosen, and the study sample consisted of 170 athletes (97 females, 73 males) with sports injuries and 90 athletes (49 females, 41 males) without sports injuries, totally 260 volunteers. The demographic information form developed by the researchers, the Adolescent Form of the Quality of Life for Children (PedsQL) developed by Varni et al. (1999), the Adolescent Form of the Age of 13-18, and the Causes of Injury in Sports Questionnaire prepared by Alkaabi (2015) were used as data collection methods. As a result, it was found that female athletes had more sports injuries in adolescent athletes than men. The number of athletes who suffered injuries in defense sports is higher than in other branches. As a result, it has been determined that sports injury negatively affects the quality of life. It was found as a result of the study data that they experienced more injuries in training than in competitions. Since the injury is mostly in the winter season and the athletes stated that they did not use protective equipment during the injury, the trainers should be informed, they should be thoughtful about taking the necessary precautions and precautions and should be offered the necessary supervision. Keywords: Adolescent athlete, injury, quality of life

ObjectivesThere have been recent calls for the application of the complex systems approach in sports injury research. However, beyond theoretical description and static models of complexity, little progress has been made towards formalising this approach in way that is practical to sports injury scientists and clinicians. Therefore, our objective was to use a computational modelling method and develop a dynamic simulation in sports injury research.MethodsAgent-based modelling (ABM) was used to model the occurrence of sports injury in a synthetic athlete population. The ABM was developed based on sports injury causal frameworks and was applied in the context of distance running-related injury (RRI). Using the acute:chronic workload ratio (ACWR), we simulated the dynamic relationship between changes in weekly running distance and RRI through the manipulation of various ‘athlete management tools’.ResultsThe findings confirmed that building weekly running distances over time, even within the reported ACWR ‘sweet spot’, will eventually result in RRI as athletes reach and surpass their individual physical workload limits. Introducing training-related error into the simulation and the modelling of a ‘hard ceiling’ dynamic resulted in a higher RRI incidence proportion across the population at higher absolute workloads.ConclusionsThe presented simulation offers a practical starting point to further apply more sophisticated computational models that can account for the complex nature of sports injury aetiology. Alongside traditional forms of scientific inquiry, the use of ABM and other simulation-based techniques could be considered as a complementary and alternative methodological approach in sports injury research.

This paper utilized a non-empirical theoretical research framework for the purpose of examining possible solutions to the ethical and methodological dilemmas facing educational researchers. Two questions guided the examination: a) How relevant is research ethics in education research? and b) Which paradigm is a good fit for education research? A study of over two decades of seminal works and conference presentations revealed that education research is subject to the same professional code of ethics and guidelines as other Human and Social Sciences Research; therefore, educational researchers should avoid questionable practices by adhering to the “relativist utilitarian ethics of consequences” in the research process. While no single paradigm was identified as a good fit for education research, the quantitative–qualitative continuum, mixed–methods research, and alternative ways of teaching research methods courses were considered as possible approaches for addressing the methodological dilemmas that educational researchers encounter. Instructors of research methods courses are therefore expected to reflect on and re-evaluate the different ways in which philosophy, pedagogical strategies, and learning goals influence the redesign of their course.

For the full implementation of strategic goals of public administration, as well as a worthy representation of the interests of the state at the international level, civil servants must have high foreign-language professional competencies. Practical issues of educational and training programs in the field of development of these competencies are carefully studied by the author. The current state of the level of language training of future civil service students (undergraduates, graduates and postgraduates) at the Institute for Social Sciences at the Russian Presidential Academy of National Economy and Public Administration is analyzed. The analysis includes the definition and formulation of tasks, goals, curriculum technologies, qualification requirements of future civil servants, ways of improving the quality of their knowledge of foreign languages and improving the methodological support of foreign-language teaching, and the creation of textbooks and teaching aids to solve the above-mentioned problem, etc. The research methods include theoretical research, analytical research methods, methodology of empirical research and methods of comparative research. The conclusions are based on the results of the analysis. Ways of improving programs for better development of civil servants’ foreign-language professional competencies are outlined. Some recommendations for teachers and education managers are presented.

A physically active lifestyle and active participation in sports is important, for adults as well as for children. Reasons to participate in sports and physical activity are many: pleasure and relaxation, competition, socialization, maintenance and improvement of fitness and health, etc. In general, when compared to adults, the risk for sports injury resulting from participation in sports and free play is low in children.1 Despite this relatively low risk, sports injuries in children are a fact of life, which calls for preventive action. In order to set out effective prevention programmes, epidemiological studies need to be done on incidence, severity, and aetiology of sports injuries. Also the effect of preventive measures needs to be evaluated. In the following chapters various authors will describe these aspects of sports injuries in children, regarding specific sports. This chapter describes briefly some current concepts regarding the epidemiology and prevention of sports injuries as a means of introduction to these chapters.

This paper aims to construct a theoretical research framework for sustainable urban freight transport (SUFT) from the perspectives of future urban development and distribution innovations, and appropriate research methods are discussed, as well. Urban freight transport plays a critical role in the promotion of sustainable and livable cities. According to the literature review, considerable research on SUFT has focused on resolving some specific problems with a short-term perspective. The existence of an urban freight transport strategy is noted, which should be embedded in an overall sustainable development strategy with a long-term perspective (approximately 20–30 years). Nevertheless, considerable research has paid scant attention to the long-term planning of SUFT. Given this, this paper contributes to the closure of this gap. First, this paper presents a systematic literature review (SLR) to highlight published papers involving foresight research within the past 16 years (2003–2018). This step contributes to the understanding of research methods that can be used in foresight research. Subsequently, this paper discusses the impacts of both urban development and distribution innovations on future SUFT, and these effects are used to select the appropriate methods to construct the theoretical research framework. Finally, the theoretical research framework of long-term planning for SUFT is developed on the basis of two future perspectives: the trends of urban development and the application of urban distribution innovations. This framework is intended to provide an approach to designing sustainable urban logistics, taking into account urban development and distribution innovations.
