Book Description
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.

Sports-Related Concussions in Youth

Sports-Related Concussions in Youth PDF Author: National Research Council

ISBN: 0309288037
Category : Medical
Languages : en
Pages : 215

Book Description
In the past decade, few subjects at the intersection of medicine and sports have generated as much public interest as sports-related concussions - especially among youth. Despite growing awareness of sports-related concussions and campaigns to educate athletes, coaches, physicians, and parents of young athletes about concussion recognition and management, confusion and controversy persist in many areas. Currently, diagnosis is based primarily on the symptoms reported by the individual rather than on objective diagnostic markers, and there is little empirical evidence for the optimal degree and duration of physical rest needed to promote recovery or the best timing and approach for returning to full physical activity. Sports-Related Concussions in Youth: Improving the Science, Changing the Culture reviews the science of sports-related concussions in youth from elementary school through young adulthood, as well as in military personnel and their dependents. This report recommends actions that can be taken by a range of audiences - including research funding agencies, legislatures, state and school superintendents and athletic directors, military organizations, and equipment manufacturers, as well as youth who participate in sports and their parents - to improve what is known about concussions and to reduce their occurrence. Sports-Related Concussions in Youth finds that while some studies provide useful information, much remains unknown about the extent of concussions in youth; how to diagnose, manage, and prevent concussions; and the short- and long-term consequences of concussions as well as repetitive head impacts that do not result in concussion symptoms. The culture of sports negatively influences athletes' self-reporting of concussion symptoms and their adherence to return-to-play guidance. Athletes, their teammates, and, in some cases, coaches and parents may not fully appreciate the health threats posed by concussions. Similarly, military recruits are immersed in a culture that includes devotion to duty and service before self, and the critical nature of concussions may often go unheeded. According to Sports-Related Concussions in Youth, if the youth sports community can adopt the belief that concussions are serious injuries and emphasize care for players with concussions until they are fully recovered, then the culture in which these athletes perform and compete will become much safer. Improving understanding of the extent, causes, effects, and prevention of sports-related concussions is vitally important for the health and well-being of youth athletes. The findings and recommendations in this report set a direction for research to reach this goal.

The Brain on Youth Sports

The Brain on Youth Sports PDF Author: Julie M. Stamm
Publisher: Rowman & Littlefield
ISBN: 1538143208
Category : Health & Fitness
Languages : en
Pages : 245

Book Description
A 2022 Choice Reviews Outstanding Academic Title Dispels the myths surrounding head impacts in youth sports and empowers parents to make informed decisions about sports participation “They’re just little kids, they don’t hit that hard or that much.” “Chronic Traumatic Encephalopathy (CTE) only happens to former NFL players.” “Youth sports are safer than ever.” These are all myths which, if believed, put young, rapidly maturing brains at risk each season. In The Brain on Youth Sports: The Science, the Myths, and the Future, Julie M. Stamm dissects the issue of repetitive brain trauma in youth sports and their health consequences, explaining the science behind impacts to the head in an easy-to-understand approach. Stamm counters the myths, weak arguments, and propaganda surrounding the youth sports industry, providing guidance for those deciding whether their child should play certain high-risk sports as well as for those hoping to make youth sports as safe as possible. Stamm, a former three-sport athlete herself, understands the many wonderful benefits that come from playing youth sports and believes all children should have the opportunity to compete—without the risk of long-term consequences.

No Game for Boys to Play

No Game for Boys to Play PDF Author: Kathleen Bachynski
Publisher: UNC Press Books
ISBN: 1469653710
Category : Health & Fitness
Languages : en
Pages : 297

Book Description
From the untimely deaths of young athletes to chronic disease among retired players, roiling debates over tackle football have profound implications for more than one million American boys—some as young as five years old—who play the sport every year. In this book, Kathleen Bachynski offers the first history of youth tackle football and debates over its safety. In the postwar United States, high school football was celebrated as a "moral" sport for young boys, one that promised and celebrated the creation of the honorable male citizen. Even so, Bachynski shows that throughout the twentieth century, coaches, sports equipment manufacturers, and even doctors were more concerned with "saving the game" than young boys' safety—even though injuries ranged from concussions and broken bones to paralysis and death. By exploring sport, masculinity, and citizenship, Bachynski uncovers the cultural priorities other than child health that made a collision sport the most popular high school game for American boys. These deep-rooted beliefs continue to shape the safety debate and the possible future of youth tackle football.

Pages : 763

Book Description
Dr. Tommy John's unique program: a diet, lifestyle, and movement plan (Rethink. Rebuild. Replenish. Recover) for injury- and performance-proofing young athletes in every sport Beginning as early as age 6 and continuing through the teenage years and on into their twenties, both male and female athletes are more at risk of serious injuries at younger ages than ever before. Dr. Tommy John, son of lefty pitcher Tommy John and also a sports performance and healing specialist, offers an invaluable diet, lifestyle, and movement plan (Rethink. Rebuild. Replenish. Recover) for injury- and performance-proofing young athletes in every sport. Dr. John explores the sudden rise of Tommy John surgeries being performed on young athletes today, as well as the many injuries--and the surgeries required to fix them--increasing at an alarming rate in baseball and all youth sports. Dr. John's book outlines the three top causes behind this "injury epidemic": The American lifestyle, the business of youth sports (from coaches to corporations), and the decisions we believe as parents are truly benefiting our children. Minimize Injury, Maximize Performance focuses on prevention, and also offers tips on how to tailor the advice for athletes coming back from an injury, with over 120 black and white photographs.

That's Gotta Hurt

That's Gotta Hurt PDF Author: Dr. David Geier
Publisher: University Press of New England
ISBN: 1512600695
Category : Medical
Languages : en
Pages : 314

Book Description
In That's Gotta Hurt, the orthopaedist David Geier shows how sports medicine has had a greater impact on the sports we watch and play than any technique or concept in coaching or training. Injuries among professional and college athletes have forced orthopaedic surgeons and other healthcare providers to develop new surgeries, treatments, rehabilitation techniques, and prevention strategies. In response to these injuries, sports themselves have radically changed their rules, mandated new equipment, and adopted new procedures to protect their players. Parents now openly question the safety of these sports for their children and look for ways to prevent the injuries they see among the pros. The influence that sports medicine has had in effecting those changes and improving both the performance and the health of the athletes has been remarkable. Through the stories of a dozen athletes whose injuries and recovery advanced the field (including Joan Benoit, Michael Jordan, Brandi Chastain, and Tommy John), Dr. Geier explains how sports medicine makes sports safer for the pros, amateurs, student-athletes, and weekend warriors alike. That's Gotta Hurt is a fascinating and important book for all athletes, coaches, and sports fans.
