Frontal Plane Knee Projection Angle and Functional Performance in Adolescent Female Volleyball Players

This observational study aims to examine the relationship between frontal plane knee projection angle, dynamic balance, agility performance, and ankle dorsiflexion mobility in adolescent female volleyball players. Frontal plane knee projection angle will be assessed during a single-leg squat using two-dimensional video analysis. Dynamic balance will be evaluated with the Lower Quarter Y-Balance Test, agility with the T-Test, and ankle dorsiflexion mobility with the Weight-Bearing Lunge Test. All measurements will be completed in a single session under standardized field conditions, and no intervention or experimental treatment will be applied. By investigating how frontal plane knee alignment is associated with functional performance measures, this study may help improve the understanding of biomechanical factors related to movement quality and injury risk in adolescent female volleyball players.

Acute Effects of Different Warm-Up Protocols in Professional Taekwondo Athletes

The goal of this clinical trial was to compare the immediate effects of three warm-up methods in professional taekwondo athletes. The warm-up methods were dynamic warm-up, Theraband exercises, and foam rolling. The main questions were whether these warm-up methods had different immediate effects on: muscle activity and the timing of muscle activation; movement-related measures recorded using an inertial measurement unit (IMU); agility; and range of motion. Researchers compared the three warm-up methods to determine whether they produced different immediate changes in these measures. Participants completed the warm-up protocols according to the study procedures. They also performed physical and movement tests, including single-leg squat and jump squat tasks. Researchers measured lower-limb muscle activity using surface electromyography (EMG). They also used an IMU and performance tests to assess movement, agility, and range of motion.

The Effects of Core Stabilization Exercises on Physical Performance, Balance, and Coordination in Young Football Players

This study aims to examine the effects of a 6-week core stabilization exercise program on balance, coordination, and core endurance parameters in young soccer players. Soccer is a sport that requires multifaceted skills such as balance, agility, and endurance, and it is well-known that stabilization of the lumbopelvic region (core) plays a critical role in enhancing performance and reducing the risk of injury. The study will include male volunteer athletes aged 14-17 years from the Alayköy Football Club Under-17 team in Cyprus. Participants will be randomly assigned to an exercise group (n=10) and a control group (n=10). The exercise group will undergo a progressive core stabilization program (plank, side plank, dead bug, etc.) twice a week for 6 weeks in addition to their routine training, while the control group will continue only with routine soccer training. Data will be collected using the Y-Balance Test, Pro-Agility Test, Squat Repetition Test, McGill Core Endurance Tests (Flexion and Lateral Bridge), and Prone Extension Test. Data analysis will be performed using Statistical Package for the Social Sciences version 27.0; the Wilcoxon test will be used for within-group changes, and the Mann-Whitney U test will be used for between-group comparisons. Ethical committee approval was obtained from the Scientific Research and Publication Ethics Committee (BAYEK) of the European University of Lefke, and informed consent forms will be collected from participants and their parents.

Virtual Reality Training Using Wii Fit in Children With Cerebral Palsy

The goal of this clinical trial is to determine whether virtual reality (VR) training using the Nintendo Wii Fit can improve balance, gross motor function, and agility in children aged 7-14 years with spastic cerebral palsy (GMFCS Levels I-II). The main questions it aims to answer are: Does Wii Fit-based VR training improve balance more than conventional physiotherapy? Does VR training enhance gross motor skills such as standing, walking, running, and jumping? Does VR training improve agility in children with cerebral palsy? Does VR training increase enjoyment and engagement during therapy? Researchers will compare Wii Fit-based VR training with conventional physiotherapy to determine which approach leads to greater improvements in motor function. Participants will: Attend 18 sessions over 6 weeks (3 sessions per week). Perform either VR-based exercises using the Wii Fit Balance Board or traditional physiotherapy exercises. Complete pre- and post-intervention assessments using the Pediatric Balance Scale, GMFM-88 (domains D and E), BOT-2 agility subtest, and the PACES enjoyment scale. This study aims to explore a fun, cost-effective, and engaging rehabilitation strategy that may improve functional independence and overall quality of life for children with cerebral palsy.

Speed, Agility, and Quickness Training

This study aims to evaluate the effects of Speed, Agility, and Quickness (SAQ) training on the physical, cognitive, and skill performance of university soccer major students in China. The hypothesis is that SAQ training will significantly improve students' physical fitness (e.g., speed, agility), cognitive functions (e.g., reaction time, decision-making), and soccer skills (e.g., ball control, passing). The study will recruit 52 university soccer major students, randomly assigned to an intervention group and a control group, with 26 students in each group. The study will last for 12 weeks, and tests will be conducted before, during, and after the intervention. The expected outcome is that the intervention group will show superior performance in various tests compared to the control group, thereby validating the effectiveness of SAQ training.
