Dance-related injuries have become a field of great interest to researchers, with the most commonly reported injuries being those sustained by ballet dancers. However, there is a lack of research into injuries sustained by those who perform modern and hip-hop dance.

This study aimed to compare match performance in the group and knockout stage of the UEFA Champions League (UCL) for players in different playing positions. The information on physical and technical performances was collected during all UCL matches (n=125) in the 2022/23 season. Players' observations (n=1387) were classified according to their playing positions as central defender (CD; n=471), fullback (FB; n=283), central midfielder (CM; n=376), winger (WM; n=137) and forward (FW; n=104). No differences in technical performance between the group and knockout stage were found for CDs, FBs, CMs, and WMs, while only FWs achieved significantly less shots on target (Cohen's d (d=0.46), total passes (d=0.54), successful passes (d=0.49), and more duels (d=0.39) in the knockout compared to the group stage. The CDs, CMs, and WMs covered greater distance at moderate (d=0.46-0.63) and high (d=0.29-0.38) speeds in the knockout compared to the group stage, while no differences in physical performance between the group and knockout stage were found for FBs and FWs. This study demonstrated that (i) the technical performance of UCL players was in general stable irrespective of the competition stage, (ii) matches played in the knockout stage were characterized by greater match intensity compared to the matches played in the group stage of UCL for CDs, CMs, and WMs. These findings may help football coaches in the decision-making process when selecting the players for specific matches and designing training programs.

Background and Objectives: Hypermobility has been linked to decreased knee performance, including isokinetic and isometric knee strength. This study aimed to determine whether athletes with and without knee hyperextension have different hamstring-to-quadriceps strength (H/Q) ratios and to investigate the associations between knee hyperextension indices and H/Q ratios and anthropometric characteristics. Materials and Methods: The sample consisted of 47 healthy male athletes without knee injuries aged 23.48 ± 3.54 years. The variables included the degree of knee hypermobility, isokinetic parameters of the leg musculature, and anthropometric indices. Differences between athletes with and without hyperextension were calculated using an independent sample t-test, effect sizes, and discriminant analysis, while associations between the variables were checked by Pearson's correlation coefficient and multiple regression analysis. Results: Athletes with hyperextended knees had shorter legs (t value = −2.23, p = 0.03, moderate ES) and shins (t = −2.64, p = 0.01, moderate ES) and a lower H/Q ratio at an angular velocity of 60°/s (t = −2.11, p = 0.04, moderate ES) than those in the nonhyperextended group did; these differences were supported by discriminant analysis (Wilks' L = 0.60, p = 0.01). An increase in the H/Q ratio at an angular velocity of 60°/s was associated with the degree of knee hypermobility (R = −0.29, p = 0.04). Conclusions: This research showed that athletes with knee hypermobility have weaker hamstring strength and thus a lower H/Q strength ratio at lower angular velocities. These findings suggest that targeted strength training programs for leg (i.e., hamstrings) muscles should help individuals with knee hypermobility. [ABSTRACT FROM AUTHOR]

Hip-hop is a cultural movement that captures different dance styles. The complexity of choreography is increasing, and the requirements for the physical condition are simultaneously higher. To reduce the risk of muscle and joint injuries, it is essential that dancers understand the importance of proper nutrition. The purpose of our study was to analyse the use and knowledge about food supplements in the daily diet of hip-hop dancers. We also wanted to highlight the problem in the lack of nutritional knowledge and to determine if this affects their body composition. The sample consisted of 114 hip-hop dancers, average age 17.2±2.2 years, participating in adult categories, all members of the Dance Sport Federation of Slovenia and the International Dance Organization. For basic information, an anonymous questionnaire was used, followed by questions about food supplements, and doping. Body composition was analysed with an InBody 720 bioelectrical impedance device (Biospace Co., Ltd). The data were statistically processed using SPSS statistical software. We established that 42.1% of the surveyed dancers consume nutritional supplements, of which only 10.5% do so regularly. The use of food supplements and better nutrition knowledge is prevalent among more successful dancers. There is still a high percentage of those who do not consume dietary supplements, probably due to ignorance and insufficient information (48%). Better body composition in more successful dancers does not influence the knowledge and/or use of dietary supplements. Some interventional programmes about substance use and misuse might be useful in educating dancers and choreographers. [ABSTRACT FROM AUTHOR]
