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 Clinical Mechanics and Kinesiology written by Janice K. Loudon and published by Human Kinetics. This book was released on 2013-04-12 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clinical Mechanics and Kinesiology With Web Resource provides a solid foundation so that students of physical therapy, occupational therapy, and athletic training can understand biomechanics and functional anatomy as they relate to both normal and abnormal movement. Written by active clinicians with more than 40 combined years of clinical and teaching experience, this text is also a practical reference for rehabilitation professionals working with a range of populations and pathologies. Taking a clinical approach not found in other texts, Clinical Mechanics and Kinesiology follows a logical progression that maximizes learning. It first presents biomechanical principles that students must understand in order to examine and treat clients and patients undergoing rehabilitation. Next, it explores muscle and nerve physiology and function of the muscle and joint systems. Then the focus shifts to applying those concepts to specific joints. Divided into 10 regions, each joint is evaluated by the bones that make up the joints; the joint articulation, anatomy, and function; and the muscles that act on the joints. In the final section of the text, students gain insight into full-body movement patterns of particular concern to rehabilitation specialists. They will examine not only the usual topics of posture and walking gait but also running gait and the mechanics of jumping and cutting—some of the most common sources of injury. Clinical Mechanics and Kinesiology is enhanced with over 360 pieces of full-color art. Unique combination figures integrate detailed bone illustrations and photos. Medical art displays locations of bones, muscles, and ligaments. Arthrokinematic motions are clearly shown with the appropriate skeletal locations, making it easy for students to see how a particular motion relates to the rest of the body. Several other features also aid in students’ learning and retention: • A one-year subscription to Musculoskeletal Anatomy Review, an online anatomy program, provides an interactive forum for reviewing regional structural anatomy. • Clinical Correlations included in each chapter help students increase their understanding of biomechanics and kinesiology and apply the theoretical content to clinical practice. • Problem Sets and Practice It sidebars with activities in chapters 1 and 2 assist students in applying and mastering biomechanical concepts. • Pedagogical aids such as chapter objectives and conclusions, key points, glossary terms, and review questions highlight important information so students can quickly grasp and review the main points. Included with each new text is a key code allowing students one-year access to the online anatomy program Musculoskeletal Anatomy Review. This engaging supplement offers a regional review of structural anatomy with exceptionally detailed, high-quality graphic images—the majority provided by Primal Pictures. Students can mouse over muscles and click for muscle identification. Each chapter features a pretest and posttest evaluation to help students pinpoint knowledge gaps and test their retention. Students may take the pretest multiple times (it is generated randomly so it will never be the same), but students may take the posttest only once. Test results can be printed and turned in, giving instructors the option to use the tests as a grading tool. In addition, instructors will have online access to an instructor guide, image bank, and test package. The instructor guide further encourages students’ learning by offering class assignments and lab activities not featured in the book. The class assignments, at least three per chapter, are quick activities that can be completed in class. The lab activities are longer assignments intended to be completed outside the classroom by pairs of students. Each lab contains an overview, a statement of purpose, a list of equipment needed, and instruction on data collection and analysis. Written for students and practitioners of rehabilitation programs, Clinical Mechanics and Kinesiology provides a foundation in kinesiology reinforced by numerous clinically applicable examples. Students will gain a strong understanding of mechanical principles governing human motion, with particular knowledge of both normal and abnormal functional motions, and be able to apply their knowledge directly to rehabilitation protocols.

Download or read book Injury Prevention in Youth Football Players written by Hanna Lindblom and published by Linköping University Electronic Press. This book was released on 2019-10-08 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background With 17–35% of all 14-year-olds in Sweden being active in football, injuries do occur, most frequently during match play. Based on knowledge of injury mechanisms and risk factors, different injury prevention exercise programmes (IPEPs) have been developed. In this thesis, the Swedish IPEP Knee Control was used as a model for injury preventive training. Aim The overall aim of this thesis was to improve our understanding of the effects of the Knee Control injury prevention exercise programme on sports performance and jump-landing technique, as well as exploring programme implementation and coach experiences of using the programme in youth football. Methods Studies I and IV were cluster-randomised trials focusing on the performance effects of Knee Control. Study I included four teams with 41 female youth football players (mean age 14). The intervention group used Knee Control twice weekly for 11 weeks, whereas the control group teams did their usual training. Knee Control includes six different exercises at four levels of difficulty and with partner exercises and is meant to be used during warm-up at every training session. Performance was tested using a battery of balance, agility, jump and sprint tests at baseline and follow-up at an indoor venue. Study IV had a similar set-up but included two different interventions: Knee Control and a new, further-developed version of the programme, Knee Control+, which were studied during an eight-week intervention involving eight youth football teams, four male, four female (mean age 14), with 77 players. Similar, but not identical, performance tests were used in Study IV, along with drop vertical jumps and tuck jump assessment to assess jump-landing technique. Studies II and III focused on the implementation context. Study II was questionnaire based, using the RE-AIM framework covering the reach, effectiveness, adoption, implementation and maintenance of Knee Control. Coaches for female youth teams (n=352), one representative of the national football association and representatives of eight district football associations responded to web-based questionnaires. Data collection was performed two years after the nation-wide implementation of Knee Control started. Study III was a qualitative study that followed up on the results of Study II. Interviews were conducted with 20 coaches for female football teams and analysed using qualitative content analysis. The interviews focused on factors that affected the adoption and use of Knee Control. All 20 coaches had experience of Knee Control. Results Limited positive effects were seen on jump-landing technique in girls, with the total tuck jump assessment score improving, as well as two separate criteria, the number of jumps accomplished during the 10-second test and additionally an increased knee-flexion angle upon landing from a drop vertical jump. No improvements on the performance tests were found in either Study I or Study IV. Both studies, however, suffered from low player compliance with the IPEPs and as a result low training dosage. No major differences in results were seen between Knee Control and Knee Control+ in Study IV. Study II showed that 91% of the responding coaches were familiar with Knee Control, they perceived the programme to be effective, 74% had started to use it, and it was fairly well maintained over time. However, only one third of the coaches used the programme every week and few used the whole programme. There were no formal policies for programme implementation and use in the district football associations and clubs. Study III showed that the coach was vital for programme use but needed social support, buy-in from players, resources and a feasible programme to facilitate programme adoption and use. When facing challenges with Knee Control implementation and use, the coaches did their best to work around these obstacles; for example, by modifying the programme content or dosage. Conclusions In conclusion, limited positive effects on jump-landing technique were seen in girls, potentially affecting risk factors for injury positively. No clinically meaningful effects from Knee Control or Knee Control+ were seen on performance tests as measured in the studies in either boys or girls. This may be related to the low training dosage. The high programme reach, perceived effectiveness, adoption and fairly high maintenance of Knee Control were positive. The modifications of programme content and/or dosage were concerning but will hopefully decrease with a more user-friendly programme. Bakgrund I och med att 17–35% av alla 14-åringar i Sverige är aktiva inom fotboll så uppkommer en del skador, oftast i samband med matcher. Utifrån kunskap om skadesituationer och riskfaktorer för skador har olika skadeförebyggande träningsprogram utvecklats. I denna avhandling användes det svenska skadeförebyggande programmet Knäkontroll som modell för skadepreventiv träning. Syfte Det övergripande syftet var att öka förståelsen för effekterna av Knäkontroll på prestationsförmåga och hopp-landningsteknik, programmets implementering och tränarnas erfarenheter av att använda programmet inom svensk ungdomsfotboll. Metod Studie I och Studie IV var klusterrandomiserade studier som undersökte effekterna på prestationsförmågan av att träna Knäkontroll. Studie I inkluderade 41 flickfotbollsspelare (genomsnittsålder 14 år). Interventionsgruppen använde Knäkontroll två gånger per vecka i 11 veckor, medan kontrollgruppen tränade som vanligt. Knäkontroll involverar sex olika övningar på fyra svårighetsgrader och med tillhörande parövningar och ska användas vid uppvärmningen inför varje fotbollsträning. Prestationsförmågan testades inomhus med ett batteri av olika tester för balans, snabbhet, hopp- och sprintförmåga vid baslinje och uppföljning. Studie IV hade ett likartat upplägg men inkluderade två olika interventioner: Knäkontroll och en vidareutvecklad version av programmet, Knäkontroll+. Studien pågick åtta veckor i åtta fotbollslag (fyra pojk-, fyra flicklag) med 77 spelare (genomsnittsålder 14 år). Liknande test för prestationsförmåga användes som i studie I, men även drop vertical jumps och tuck jumps för att bedöma hopp-landningsteknik. Studie II och Studie III fokuserade på implementeringskontexten, det vill säga implementeringen av Knäkontroll ute i fotbollslag. Studie II var en enkätstudie som med hjälp av ramverket RE-AIM (reach, effectiveness, adoption, implementation and maintenance) utvärderade implementeringen av Knäkontroll. Tränare för flickfotbollslag (n=352), en representant för Svenska Fotbollförbundet och representanter för åtta distriktsförbund besvarade de webbaserade enkäterna. Datainsamlingen gjordes två år efter att den nationella implementeringen av Knäkontroll startade. Studie III var en kvalitativ studie som fördjupade resultaten av Studie II. Intervjuer genomfördes med tjugo tränare för flick- och damfotbollslag och analyserades med kvalitativ innehållsanalys. Intervjuerna fokuserade på faktorer som påverkade tränarnas upptag och användning av Knäkontroll. Alla tränare hade erfarenhet av Knäkontroll sedan tidigare. Resultat Begränsad positiv effekt sågs på hopp-landningsteknik bland flickorna i studie IV, med en förbättrad totalpoäng på tuck jumps, på två kriterier i tuck jump, ökat antal hopp under testets 10 sekunder samt en ökad knäflexionsvinkel vid landning från drop vertical jumps. Ingen förbättring av prestationsförmågan sågs i Studie I eller Studie IV. I båda studierna var spelarnas närvaro på fotbollsträningar låg, vilket även gav en låg träningsdos av Knäkontroll. Inga större skillnader i resultat sågs mellan Knäkontroll och Knäkontroll+ i Studie IV. Studie II visade att 91% av tränarna kände till Knäkontroll, att tränarna upplevde att programmet var effektivt, 74% hade också börjat använda programmet och användandet bibehölls också förhållandevis väl över tid. Däremot använde endast 1/3 av tränarna programmet varje vecka och få använde hela programmet. Det saknades riktlinjer för programmets implementering och användning inom distriktsförbund och klubbar. Studie III visade att tränaren var oumbärlig för programmets användning men behövde mer socialt stöd, intresse från spelarna och resurser utöver ett användarvänligt program för att underlätta det preventiva arbetet. När tränarna ställdes inför utmaningar gjorde de sitt bästa för att kringgå problemen, till exempel genom att modifiera programmets innehåll eller dosering, för att ändå kunna använda programmet. Konklusion Sammanfattningsvis sågs begränsade positiva effekter på hopplandningsteknik hos flickorna, vilket möjligen påverkar riskfaktorerna för skada positivt. Inga kliniskt meningsfulla effekter av Knäkontroll eller Knäkontroll+ sågs på prestationstesterna hos varken pojkar eller flickor. Detta kan vara relaterat till den låga träningsdosen. Knäkontrollprogrammets stora spridning, högt skattade effektivitet, höga upptag och förhållandevis goda bibehållande var positivt. De modifieringar av programmets innehåll och/eller dosering som sågs var oroväckande men kan förhoppningsvis minska av ett mer användarvänligt program.
