This book was released on 2010 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the incidence of non-contact anterior cruciate ligament (ACL) injuries is greater among women than men athletes, the factors that contribute to this greater risk of injury are not well understood. One relevant question is whether decision making during landing influences the biomechanical and neuromuscular factors thought to contribute to ACL injury, and whether these effects differ as a function of task and sex. The purpose of this study was thus to examine the effects of decision making on the neuromechanics of two-footed landing tasks in women and men. Twenty-nine healthy young adults (13 women; 16 men) completed a series of two-footed drop landing and drop-jump tasks under preplanned and decision-making conditions. Biomechanical and electromyographic data were collected. Repeated measures ANOVA was used to determine the effect of decision making on hip, knee, and ankle kinematics and kinetics, and on proactive and reactive muscle activity, as a function of task and sex. Multiple linear regression was used to assess the relationship between select knee biomechanical variables and proactive muscle activity. Decision making had numerous effects on lower extremity kinematics, kinetics, and neuromuscular control, many of which were task-specific. Under decision-making conditions, individuals exhibited similar joint postures at initial ground contact and similar amounts of reactive muscle activity across tasks. The majority of the observed modifications in neuromechanics suggested a default towards the preplanned drop landing strategy under decision-making conditions. Some effects of decision making on joint mechanics and reactive muscle activity varied with sex, although the extent to which these dissimilar effects modified relative ACL loading is not known. Knee flexion at initial contact, peak knee abduction, and peak knee adduction moment were significantly related to the proactive activity of several, primarily lateral, muscles of the lower extremity, independent of task and decision-making condition. These results indicate that decision making influences landing mechanics and neuromuscular control and that these effects are generally task-dependent and, in some cases, sex-dependent. The results also suggest that, in both women and men, drop landings and drop-jumps performed under decision-making conditions are no more dangerous, with respect to ACL loading, than preplanned drop landings.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the higher incidence of anterior cruciate ligament injuries in pediatric female populations, limited research has investigated sex-differences in youth biomechanics. Furthermore, research involving jump mechanics typically requires participant to follow a set protocol, such as sticking the landing. To reduce variability and improve reliability, trails where participants fail to meet the required protocol are discarded; however, significant clinical findings may be elucidated from these trials. The purpose of this thesis was to provide a complete biomechanical analysis of unanticipated single-leg drop-jump landings in youth athletes. Thirty-two healthy youth athletes completed unanticipated single-leg drop-jump landings on their dominant limb. Trials where participants shifted foot position or touched the ground with the contralateral leg were categorized as failed. Drop-jump landings were time-normalized using landmarks within the drop-jump task. Statistical parametric mapping (SPM) determined time-varying sex-differences in muscle onset time, co-activation, kinematics and kinetics. Wilcoxon signed-rank tests and paired sample t-tests compared lower-limb kinematics, centre-of-mass excursion and muscle activation amplitudes during the successful and failed landings. A logistic regression model was also fit to predict the likelihood of a successful landing. SPM identified significantly greater trunk flexion angle in males during the deceleration, flight, and landing phase of the drop-jump. Greater quadriceps-gastrocnemius co-activation was identified during the flight phase in female participants and independent sample t-test identified longer muscle onset time in the vastus lateralis of male participants. When comparing failed and successful landings greater hip abduction and less external rotation angles were observed during the successful trials. In addition, greater preparatory muscle activation was observed in the rectus femoris and semitendinosus during the flight phase of the failed landings. A logistic regression model, which included eight kinematic and neuromuscular variables, offered a training classification accuracy of 70% and a leave-one-out cross-validation accuracy of 65%. In conclusion, females land in a more erect posture and may be less effective at dissipating landing forces. In addition, greater co-activation and shorter pre-activations of the lower limb musculature may indicate a less effective muscle activation strategy in females. Furthermore, hip kinematics and the surrounding musculature play an important role in controlling successful and failed unanticipated landings. The variables included in the logistic regression model indicate which key factors are linked to landing a jump successfully. Training modalities aimed at improving landing mechanics should therefore focus on modifying these variables.

Download or read book Dynamic Simulations and Data Mining of Single-leg Jump Landing written by Kristin Denise Morgan and published by . This book was released on 2014 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that 400,000 anterior cruciate ligament (ACL) injuries occur in the United States each year with the cost of ACL reconstruction surgery and rehabilitation exceeding $1 billion annually. The majority of ACL injuries are non-contact injuries occurring during cutting and jump landing movements. Because the majority of the injuries are non-contact injuries there is the potential to develop programs to reduce the risk of injury. Given our understanding of the joint kinematics and kinetics that place an individual at high risk for ACL, researchers have developed neuromuscular training programs that focus on improving muscle function in order to help the muscles support and stabilize the knee during the dynamic movements that increase the strain on the ACL. Yet, despite the implementation of these neuromuscular-based ACL injury training intervention programs ACL rates continue to rise. Thus the objective of this dissertation is to determine the cause and effect relationship between joint biomechanics and muscle function with respect ACL injury. There are four studies in this dissertation. The first two studies rely heavily on the development of subject-specific musculoskeletal models to analyze muscle contribution during single-leg jump landing. These studies will generate forward dynamic simulations to estimate muscle force production and contribution to movement. The results of these studies will aid in the development of muscle-targeted ACL injury training intervention programs. The last two studies will employ data mining techniques; such as, principal component analysis (PCA) and wavelet analysis along with stability methods from control theory, to evaluate an individual’s risk of ACL injury and determine how muscle function differs for individuals at varying levels of injury risk. The goal will be to use this information to develop a more robust ACL injury prescreening tool. The use of both dynamic simulations and data mining techniques provides a unique approach to investigating the relationship between joint biomechanics and muscle function with respect to ACL injury. And this approach has the potential to gain much needed insight about the underlying mechanism of ACL injury and help progress ACL research forward.
