Background. Hurdling is a dynamic and technically demanding sport within athletics. It requires a unique combination of speed, agility, coordination, and strength to support good technique and achievement. The ability to excel in this sport depends on the athlete’s mastery of these components, making it an interesting subject for sports science research. Objectives. This study aimed to evaluate existing research on sports biomechanics as it relates to improving hurdling performance. Materials and methods. The study was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology of the relevant literature. A total of 15 articles published between 1990 and 2023 were identified as relevant to the focus of the study and selected for in-depth analysis. Results. The findings showed that sports biomechanics research in hurdling training has mainly concentrated on the following key areas: kinematics analysis, the application of technology, and the potential injury studies. Although significant progress has been made in understanding the biomechanics of hurdling training, this study suggests the need for further and more comprehensive research. The research mentioned should delve deeper into the biomechanical factors influencing performance in order to develop optimal training methods and injury prevention strategies. Conclusions. This review underscores the importance of continued research in this area, as it has the potential to enhance training approaches and improve athletic performance in hurdling.

The objective of this paper is to evaluate the research trends in football training for young players under 18 years old in the last 15 years. Materials and methods. This was a bibliometric analysis and systematic review study. Articles published since 2008 were searched for by the keywords “Football Training” and “Football Exercise” using a comprehensive strategy on SCOPUS research journal databases. There were 1,053 articles with 4802 citations mined on October 17th, 2023. Thereafter, 217 articles were selected for further analysis by using VOS Viewer computer software. Results. The United Kingdom (67), The United States (60), and Spain (41) were the three countries that had the most publications in football training. There were 6 keyword clusters that reflected various research focuses on football training for younger players. Based on the top 10 most cited references in football training for younger players, there were several major themes that covered various aspects of the research trend and development in the last 15 years, i.e. (1) Factors in the Development of Young Football Players, (2) Tactical Analysis and Collective Behavior in Small-Sided Games, (3) Game Intensity and Activity Profile in Young Football Players, (4) Plyometric Training and Its Effects on Preadolescent Players, and (5) Injury Prevention and Neuromuscular Training in Adolescent Football Players. Conclusions. Football research for under-18 players has grown rapidly. This research trend shows that football requires not only physical and technical skills, but also social and mental aspects. Further research can be directed toward understanding and integrating holistic aspects of football coaching, including the development of non-physical skills, such as leadership, teamwork, and conflict resolution. Further investigation into the use of technology in football coaching, such as video analysis, sensor-based performance measurement, and artificial intelligence applications to provide deeper insight into player progress.

Background. The Covid-19 pandemic has caused various adaptations in the world of sports. One form of adaptation that is carried out is training at home or known as training from home (TFH). Study purpose. This study aims to see the effectiveness of the chimney jump and standing leg extension exercises carried out by volleyball athletes during training at home or training from home (TFH). Materials and methods. A total of 36 volleyball athletes with an age range of 19–20 years were selected by purposive sampling and divided into the chimney jump (KCJ) group, the standing leg extension (KSE) group, and the control group (KKL). This research is quantitative research with a quasi-experimental research design with one group pretest posttest design. The three variables used as the dependent variable are agility, balance, and athlete’s leg power which were measured before TFH and after the athlete carried out TFH for 3 months. The results of the exercise were analyzed descriptively and continued to be analyzed using the Independent Samples T-test and One-Way ANOVA. Results. There was a significant difference in the results of the leg power posttest of the three groups (
