The aim of this study was to compare the difference between dominant and non-dominant upper quarter function and static and dynamic balance between people with and without uneven shoulder. In this descriptive comparative study, 20 female students with uneven shoulders and 20 students with even shoulders aged 20 to 30 years were purposefully selected and compared. To evaluate the uneven shoulder, digital camera imaging and analysis with AutoCAD 2020 software were used. Also, Upper Quarter Y Balance Test (YBT-UQ) was used to measure upper quarter function and stork test and balance test were used to assess static and dynamic balance, respectively. Data were analyzed in SPSS software version22. The results of this study showed that there was a significant difference between the mean function of upper quarter in inferolateral direction (p=0.048) and static balance (p=0.044) between dominant and non-dominant side in people with and without uneven shoulder, and the uneven shoulder group had lower scores than with even shoulders group, but there was no significant difference in dynamic balance (p=0.372). In general, it can be concluded that the mean difference in upper quarter function in inferolateral direction and static balance between dominant and non-dominant side of individuals with uneven shoulder is higher than those with even shoulders. The alignment of the spine and the normal position of the scapula affect the function of the shoulder girdle. Based on this, it is suggested to examine the function of the upper and lower limbs in people with uneven shoulders because, despite these results, more investigations are needed in this case.https://jast.uma.ac.ir/article_3612_d3eecb1c3d49d875c11cc98d73c9eb4f.pdfUniversity of Mohaghegh ArdabiliJournal of Advanced Sport Technology2538-52599120250301Clustering of pelvic-supporting muscles activity in individuals with Lumbar Hyperlordosis in stance phase of walking: a machine learning approach3349362110.22098/jast.2025.15594.1368ENSeyedeh ShaghayeghMostafaviMsc in Sport Injuries and Corrective Exersice shahid-beheshti University, Tehran, Iran.HodaMozayaniFaculty of sport Sciences and Health,Shahid-beheshti University,Tehran,Iran.DavoodKhezriDepartment of Sport Biomechanics and Technology,Sport Sciences Research Institute,Tehran,Iran.Journal Article20240807Introduction: Lumbar Hyperlordosis (LH) is associated with lumbar muscle defects or altered muscle engagement patterns, leading to low back pain. However, the specific muscle most influential in causing this condition remains unclear. Objectives: This study aims to determine effective prescient alternative to Lumbar Hyperlordosis (LH) from muscular activity variables in stance phase of walking, in addition to discovering homogenous clusters of individuals based on the primary predictive alternative. Material and methods: The activity of Rectus Femoris (RF), Gluteus Medius (GM), and Lumbar Erector Spinae (LES) was recorded in 40 females suffering from LH while walking. Maximum activity and muscular involvement for each muscle were extracted. A multilayer perceptron artificial neural network was used to detect notable projected variables of LH. K-means clustering was then employed to identify homogeneous clusters of individuals based on the most significant predictive variable. The One-Way ANOVA test used to identify homogenous clusters. Results: The results demonstrated that RF maximum activity with an accuracy of 90.9%, was detected as the most prominent predictive variable. The One-Way ANOVA test demonstrated significant differences among the three homogeneous clusters of individuals based on Rectus Femoris maximum activity (P≤0.05). Conclusion: The classification scheme presented in this paper can describe muscle activity patterns while walking and may be useful for screening individuals suffering from Lumbar Hyperlordosis and for clinical decision-making based on clusters. The maximum activity of the Rectus Femoris is the most important factor affecting lumbar hyperlordosis, which is relevant in rehabilitation and health fields.https://jast.uma.ac.ir/article_3621_4b9b3da8d851655e741573c91e981d95.pdfUniversity of Mohaghegh ArdabiliJournal of Advanced Sport Technology2538-52599120250301Cell therapy and Regenerative medicine for treatment in sport injuries5066363910.22098/jast.2024.15289.1356ENNargesYazdan NasabMaster student of Microbial Biotechnology, Department of Biology, Faculty of Sciences, Mohaghegh Ardabili University, Ardabil, Iran.ElaheMamashliPh.D Student of Sport Physiology, Faculty of Education and Psychology, University of Mohaghegh Ardabili, Ardabil, IranNegarAshrafiDepartment of Educational Sciences, Faculty of Educational, University of Farhangian, Ardabil, IranArashAbdolmalekiDepartment of Biophysics, Faculty of Advanced Technologies, University of Mohaghegh Ardabili, Namin, IranAsadollahAsadiDepartment of Biology, Faculty of Science, University of Mohaghegh Ardabili, Ardabil, IranJournal Article20240619Background and purpose: Sports injuries are a frequent problem for athletes, and in severe cases, can lead to irreversible tissue damage, chronic pain, and restricted movement.

Ardabil, IranFarzadNobakht Sarebanmohaghegh ardabiliJournal Article20210704The environment and technologies are both changing. Changing environments are disappearing without the use of technology. The training environment and its services need to change, and if there is no immediate response to this issue, many services will be lost due to the inability to cope with the corona environment. <br />This study was conducted to design a thesis and dissertation counseling platform for sports science students (Coronavirus pandemic). Due to the limited presence of students and professors, especially non-native students in this course, there was a great need for this program among sports science colleagues. First, during a field interview, the platform features were identified and then database and user sections were designed in two stages. The results of this work could help provide specialized guidance and counseling services in sports science. We hope that by presenting the research-executive solution, we can play a desirable role in conducting research activities. This measure can also be fully responsive for post-COVID periods.https://jast.uma.ac.ir/article_4247_07d62b3c9a71c4e8b0abb1c0154b61db.pdfUniversity of Mohaghegh ArdabiliJournal of Advanced Sport Technology2538-52599120250301Investigating the role of mass media and cyberspace in the advancement and promotion of public and championship sports (Case study of East Azerbaijan Province)8297370310.22098/jast.2025.16416.1396ENShirinAaliDepartment of Sport Science Education, Farhangian University, Tehran, IranHamedKheirollahi MeidaniDepartment of Sports Management, Faculty of Educational Sciences and Psychology, University of Mohaghegh Ardabili, Ardabil, IranFariborzImaniDepartment of Sports Management, Faculty of Educational Sciences and Psychology, University of Mohaghegh Ardabili, Ardabil, Iran.FarhadRezazadehsport biomechanics, faculty of educational sciences and psychologyJournal Article20241222Mass media and cyberspace increasingly influence the advancement and promotion of both public and championship sports. In this context, this study aims to examine the role of mass media and cyberspace in economic development and employment opportunities within the sports sector, specifically focusing on East Azerbaijan Province. This research addresses the impact of media on enhancing human, financial, and infrastructural resources and its contribution to the overall development of sports. This study utilized exploratory factor analysis to identify the key factors affecting economic development and employment in sports. Before the factor analysis, the Kaiser-Meyer-Olkin (KMO) measure and Bartlett’s test of sphericity were applied to assess the appropriateness of the sample size and the intercorrelation of the variables. Additionally, model fit indices, including the Goodness of Fit Index (GFI) and Comparative Fit Index (CFI), were used to evaluate the adequacy of the structural model. The results of the factor analysis indicated that mass media and cyberspace substantially influence the development of human, financial, infrastructural, scientific, legal, and cultural resources within sports in East Azerbaijan Province. The fit indices for the structural model (GFI = 0.921, CFI = 0.893) demonstrated a good fit to the data, confirming the validity of the model. Furthermore, statistical tests revealed significant relationships between media influence and various outcomes, such as increased investment in sports, enhanced self-confidence, and the attraction of economic opportunities. The findings underscore mass media's and cyberspace's pivotal role in promoting sports at the grassroots and professional levels. The media are integral in increasing public awareness, attracting sponsorships, and fostering community engagement in sports activities. However, challenges such as unequal access to digital technologies and inadequate investment in sports infrastructure remain barriers to fully realizing the potential of media in sports development. The study concludes that for the sustainable development of sports in East Azerbaijan Province, there is a need for enhanced collaboration between the media, sports organizations, and government authorities. Long-term policies that focus on improving infrastructure and media access are essential for maximizing the benefits of mass media and cyberspace in advancing public and championship sports.https://jast.uma.ac.ir/article_3703_98350aa707b478238ae907afba8cf9c0.pdfUniversity of Mohaghegh ArdabiliJournal of Advanced Sport Technology2538-52599120250301The Effects of Neuromuscular and Mental Fatigue on Knee Kinematics and Anterior Cruciate Ligament Injury Risk in Male Soccer Players98110420610.22098/jast.2025.14220.1328ENZahraKhazaeeMSc, Department of Health and Sports Rehabilitation, Faculty of Sports Science & Health, Shahid Beheshti University, Tehran, Iran.MehdiGheitasiAssociate professor, Department of Health and Sports Rehabilitation, Faculty of Sports Science & Health, Shahid Beheshti University, Tehran, IranAmir HosseinBaratiAssociate professor, Department of Health and Sports Rehabilitation, Faculty of Sports Science & Health, Shahid Beheshti University, Tehran, Iran.SajadBagherian DehkordiDepartment of Sport Sciences, Shahrekord University, Shahrekord, IranJournal Article20231213Background: The majority of anterior cruciate ligament (ACL) injuries are non-contact, occurring most frequently during landing or changing directions in sports activities. Various factors, such as biomechanical and neuromuscular variables, have been implicated in these injuries. Recent research highlights that both physical and mental fatigue might influence the risk factors for ACL injuries by altering movement patterns during high-risk maneuvers. This study aimed to investigate the effects of neuromuscular and mental fatigue on knee kinematics and potential risk factors for ACL injuries in male soccer players during landing and crossover-cutting maneuvers. <br />Methods: Thirty professional male soccer players were randomly divided into three groups: physical fatigue (n=10), mental fatigue (n=10), and control (n=10). Experimental groups performed landing and crossover-cutting maneuvers during pre- and post-fatigue states, with kinematic data collected using a seven-camera system and Cortex software. The control group underwent identical maneuvers without fatigue protocols to ensure comparability of conditions across groups. The control group underwent the same tests without implementing fatigue protocols. Statistical analysis was conducted using repeated measures ANOVA to evaluate differences across groups and conditions.<br />Results: Physical fatigue caused a significant decrease in knee flexion at initial contact (P = 0.002), while mental fatigue showed no significant effects on kinematics. Group-by-time interaction effects were observed for knee flexion (P = 0.05), with pairwise comparisons revealing significant differences only in the physical fatigue group.<br />Conclusion: Neuromuscular fatigue alters knee kinematics, increasing ACL injury risk. Coaches should prioritize training programs that enhance fatigue resistance and proper movement mechanics.https://jast.uma.ac.ir/article_4206_a6b23f50316aa5fd4bebf073c7c684e1.pdf
