This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Soccer has a high number of knee ligament ruptures. Sex and age are factors that have an impact on these injuries. One possible reason is that females have harmful movement patterns compared to males during activities such as cutting while running. The literature still lacks studies examining the influence of age on these movements. Therefore, research is needed to determine if sex and age have an impact on the movement patterns of soccer players. The primary objective of this study was to examine if sex and age impact the joint angles and inter-joint coordination during an unanticipated cutting task in soccer players. A secondary objective compared the strength, jump performance and dynamic balance of male and female soccer players of different age groups. The study recruited healthy soccer players of different age groups. This included 11 adolescents (five males, six females) and 11 adults (seven males, four females). A 12-camera three-dimensional motion capture system recorded joint angles while participants performed an unanticipated side-step cutting task. A hand-held dynamometer measured muscle torques. Hop tests measured jump performance and the modified Star Excursion Balance Test measured dynamic balance. Principal component analysis (PCA) identified differences in joint angles. Adult males presented greater changes in hip flexion at pre-contact compared to stance/take-off than adolescent males and adult females had lower changes than adolescent females. Females had lower changes in hip flexion, and lower hip abduction and ankle inversion angles. Adolescents had greater hip internal rotation and knee flexion angles, but lower changes in knee flexion angles at pre-contact compared to stance/take-off. For inter-joint coordination, females had a more out-of-phase pattern than males in the foot/shank segment in sagittal plane. In regard to clinical measures we observed a few differences in knee extensor torque and balance, with adolescents exhibiting better results. Clinicians and coaches should be aware that these characteristics might impair performance and increase injury risk"--

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Introduction: Effects of intended cutting angle (e.g., 30 ̊, 45 ̊, 90 ̊) on kinematics are well established. Studies have typically controlled for cut angle by omitting trials if a participant cuts more than 10 ̊ from the intended angle. However, the actual angle which the participant cuts to (i.e., executed cut angle, ECA) has rarely been measured and sufficiently controlled for. Understanding relationships between ECA and commonly measured biomechanical variables are necessary, as it may affect interpretation of previous results.Additionally, epidemiological research suggests an interaction effect whereby females are more likely to injure the anterior cruciate ligament of their non-preferred leg during non-contact circumstances. Understanding interaction effects of sex and leg preference in kinematics related to anterior cruciate ligament (ACL) injuries during cutting may offer explanation for such a phenomenon, given that cutting is a major source of such injuries in some sports. Objectives: 1a) To compare entry speed and ECA between sex and leg preference during unanticipated sidestep cutting in soccer players. 1b) To determine the relationships between ECA with peak hip and knee joint angles during unanticipated sidestep cutting in soccer players. 2) To determine if an interaction effect exists between sex and leg preference on peak hip and knee angles during unanticipated sidestep cutting in soccer players.Methods: 21 adolescent and adult male and female soccer players completed unanticipated running sidestep cuts to a prescribed 45 ̊ in both directions. Lower limb kinematics were attained via 3D motion capture. Hip and knee joint angles were calculated using a joint coordinate system, and peak angles were identified during the stance phase of cutting. Hierarchical linear modeling established relationships between peak hip/knee angles and ECA/ entry speed. Analysis of variances compared ECA between sex and leg preference. Interaction effects of sex and leg preference on peak hip/knee angles were analysed during the hierarchical linear modelling. Results: Higher ECAs were related to decreased knee flexion and valgus (i.e., more varus), and increased hip flexion and internal rotation (p range =

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of mechanical vibrations has become a very common technique in the training of athletes. Some studies highlight that this kind of training is able to increase the force of the muscles, but is seems to decrease the capacity of controlling the movements by the subject. This aspect could increase the risk of ACL injuries. The aim of this project is to develop a computational model to analyze how a warming up with mechanical vibrations can a ect the biomechanical behavior of the lower limbs, with a particular attention to the aspects related to the noncontact ACL injuries. For this purpose, a lower limb model is implemented using the OpenSim software (Stanford University) to obtain the evolution of joint angles, joint torques and muscle forces during a sidestep cutting maneuver (before and after warming up). Those results are obtained by means of multibody dynamics and optimization techniques. The work also includes an economic study and an analysis of the social and environmental impact.

Download or read book Age and Sex Effects on Landing Force and Asymmetry in Youth Soccer Players written by Mara J. Cosgrove and published by . This book was released on 2016 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soccer is one of the most popular sports in the world with over 270 million people playing worldwide. Soccer is a very dynamic sport that involves movements such as jump-landing that can predispose athletes to anterior cruciate ligament injury. The current study quantified the effects of age (aged 7 to 24 years old), years from peak height velocity (aged 7 to 17 years old), and sex in youth soccer players on landing force, variability, and asymmetry during a jump-landing task. Soccer players 7 to 24 years old performed three trials of a jump-landing task on two force plates. A linear regression analysis revealed significant effects of age, years from peak height velocity, and sex on absolute landing force and normalized landing force produced by the dominant and non-dominant limb during landing. Absolute landing force increased as age and years past peak height velocity increased. As age increased, the normalized landing force in both the dominant and non-dominant limb decreased but years past peak velocity caused a significant decrease in normalized landing force of the dominant limb. Males demonstrated greater absolute and normalized landing forces compared with females. There were no significant effects on coefficient of variation and asymmetry of landing force. Jump-landing training with a focus on soft landing techniques should be initiated in soccer players based on age. Future studies are needed to study the effect of age and sex on landing kinematics in youth soccer players.

Download or read book The Effects of Heading Motion and Gender on Lower Extremity Biomechanics in Soccer Players written by Abdulmajeed Barakat Alfayyadh and published by . This book was released on 2018 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soccer continues to experience growth internationally in both men and women. Thus, it's reasonable to predict a high rate of injuries amongst those athletes since soccer includes strong physical contact. ACL injury is one of the most common injuries among athletes, and (70-84%) of ACL injuries occurs in non-contact situations, which often are associated with landing, deceleration, and sudden change of movement direction, and these situations might end with knee valgus collapse which's a common mechanism of ACL injury. Further, there are biomechanical differences of lower extremity joints in various tasks with both genders, which apparently means that the task utilized plays a crucial influence on joints dynamics. In soccer, the heading motion is one of the most common activities, which is more likely associated with landing. The purpose of this study was to investigate the effect of forward heading motion by comparing the kinetics and kinematics of lower extremity between genders during 1) a stop-jump task and 2) a jump-heading task. 10 male and 10 female soccer players performed 5 stop-jumps and 5 jumps with heading a soccer ball. Findings displayed a combination of reduced initial knee flexion, greater initial hip flexion, greater peak vertical GRF, and greater peak knee extension moments with both genders during the jump-heading task. Additionally, greater peak knee abduction angles were observed among female players during both tasks. These findings suggest that a higher risk of non-contact ACL injuries might occur during the jump-heading task compared with the stop-jump task, and this risk could be higher among female players than male players. These findings might lead soccer trainers to consider different strategies and techniques of landing after heading motions in game-like conditions. Also, PTs and rehabilitation designers who work with ACL-injured patients might consider the outcome of this study. Future studies should consider to examine ankle dynamics in addition to knee and hip in game-like conditions.
