Available in PDF, EPUB and Kindle. Book excerpt: Background: Anterior cruciate ligament (ACL) injury frequently occurs in female soccer athletes during deceleration movements such as landings. In soccer, landings mostly occur following jumping headers. Little research has been done to determine the mechanics that follow and how they compare to standard drop vertical jumps (DVJ). The purpose of this study was to analyze differences between jumps and landings in kinematics, kinetics, and muscle activation patterns in female soccer athletes to better assess the sport-specific risk for ACL injury. It was hypothesized that more biomechanical tendencies associated with ACL risk factors would emerge from soccer-specific vertical jumps (SSVJ) compared to DVJs and second landings (L2) compared to first landings (L1). Methods: 8 female participants (20.88 ± 1.17 years; 1.68 ± 0.06 m; 58.77 ± 7.65 kg) performed DVJs and SSVJs. Motion capture, force, and electromyography (EMG) data were collected to calculate joint motion, loading, and muscle activation throughout landing phases. Data were analyzed using RM-ANOVA, collapsed across jump (DVJ vs. SSVJ) and landing (L1 vs. L2). Results: Significant findings were revealed in all categories, however, kinematic variables were the most profound results. Significantly higher jump height was achieved in DVJs (p=0.008). SSVJs and L2s produced less peak hip (p=0.03; d=0.817) (p=0.007; d=1.566) and knee 2 (p=0.002; d=0.732) (p=0.002; d=1.476) flexion during landing, respectively. A significant interaction was present for trunk flexion at initial contact (p=0.034). Follow-up tests revealed no significant differences following headers. Discussion: SSVJ-L2s displayed a more erect landing at the hip and knee, a known ACL risk factor, however, it is unclear whether these results are due to trunk movement during heading. Limited results in kinetic and EMG variables may be explained by the difference in jump height achieved, therefore further investigation in a more elite population is required. Additionally, SSVJs may be a good sport-specific screening tool.

Available in PDF, EPUB and Kindle. Book excerpt: Paperback. Neuromuscular fatigue is a phenomenon of great importance in everyday life as well as being of theoretical and clinical significance. Eleven years ago there was a seminal symposium on muscle fatigue held in London. The published proceedings (Ciba Foundation Symposium 82 - Human muscle fatigue: physiological mechanisms, Pitman, London, 1981) served as an important 'state-of-the-art' reference. In the intervening period there have been many developments with respect to our understanding of fatigue of the motor output, including processes located in the skeletal muscle fibres themselves as well as problems related to various aspects of (moto) neural muscle control. However, there are still uncertainties and important questions which remain unanswered. It was felt that the time was ripe to attempt a renewed synthesis by bringing together international experts from a range of complementary research areas. In this way it was hoped that attention co

Download or read book Acute and Delayed Effects of an Exhaustive Bout of Exercise on Landing Biomechanics in Women and Men written by Kristof Kipp and published by . This book was released on 2010 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although female athletes are at greater risk of non-contact knee injuries than men, the factors that contribute to these injuries are not well understood. One important question is whether intense exercise influences the risk of knee injury, both acutely and over the following days. The purpose of this study was thus to evaluate the acute and delayed effects of an intense bout of exercise on risk factors associated with knee injury in women and men. Fifteen each of healthy young women and men performed two testing sessions, 44-52 hours apart. In each session, biomechanical data were collected during execution of sets of 10 drop vertical jumps. An initial set of drop vertical jumps was compared to a set performed immediately after an intense exercise bout on the first day and to a set performed on the second day to determine the acute and delayed effects of fatigue, respectively. A two-way repeated measures ANOVA was used to determine the effect of the exercise bout on risk factors associated with knee injury during the jump task in women and men. Intense exercise had immediate effects on joint kinematics and kinetics, patterns of joint motion and moments, and the variability of joint couplings. The acute kinematic and kinetic changes at the hip and ankle were consistent with compensatory strategies, whereas changes at the knee were consistent with an increased risk of injury. The same appeared to be true for the patterns of joint motions and moments. Acute changes in the variability of inter- and intra-limb joint couplings were also consistent with compensatory modifications of lower limb biomechanics. Delayed effects were limited to patterns of joint motion and moments, and reflected jointdependent combinations of compensatory strategies or mechanical changes that could increase knee injury risk. Although intense exercise had acute and prolonged effects on several biomechanical variables, none of the effects depended on the sex of participants. These results indicate that intense exercise has immediate and prolonged effects on landing biomechanics, independent of sex. While the majority of changes point to a compensatory strategy, a few were consistent with increased risk of knee injury.

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.
