Functional movement screen och skadeförebyggande träning hos fotbollsspelare

Magnusson, Håkan January 2014 (has links)
Bakgrund: Förekomsten av skador inom fotbollen är stor vilket drabbar den enskilde spelaren både psykiskt och fysiskt. Syfte: Att undersöka om det fanns något samband mellan låg poäng (14 poäng eller mindre) med FMS och ökad skaderisk hos manliga amatörspelare i fotboll. Material och metod: Två fotbollslag i division tre och fyra deltog i studien. Ena laget fungerade som interventionsgrupp och den andra som kontrollgrupp. Båda lagen fick utföra en FMS. Interventionsgruppen fick ett träningsprogram baserat på testresultatet medans det andra laget fungerade som kontrollgrupp tränade som vanligt. Därefter jämfördes frekvensen av skador mellan grupperna. Resultat: En skada i interventionsgrupp medan kontrollgruppen hade två stycken skador. Konklussion: FMS har ej enligt denna studie kunna förutspå skador på amatörspelare i fotboll. Vilket säkert kan bero på kort studietid och få deltagare. Nyckelord: FMS, Fotboll / Background: It´s a high injury rate in football which will affect every player both physically and mentally. Purpose: To investigate if there could be a connection between low points (14 points or lower) whith FMS and an increased injury rate för male amateur players in football. Method: Two football teams from division three and four participate in this study. One of the team acts as an intervention group and the other team as a control group. Both team made an FMS test. The intervention group got an excercise program based on the result of the test while the control group kept training as usual. After that a comparison of the injury frequency between the two groups were made. Results: One injury in the intervention group while the control group had two injuries. Conclusion: The FMS test in this study could not predict injuries among amateur football players. Which certainly could be due to the short study time and few participants. Keywords: FMS, Football

Dynamic Scheduling of Flexible Manufacturing Systems

Reddy, K. Rama Bhupal, Xie, Na, Subramaniam, Velusamy 01 1900 (has links)
To date, group scheduling research has primarily focused on examining the performance of different group heuristics under various experimental conditions. However, the dynamic selection of group heuristics has not received sufficient attention from researchers. The objective of this paper is to demonstrate a mechanism for the dynamic selection of group heuristics from several candidate alternatives by exploiting real time information from the Flexible Manufacturing System (FMS). In this regard, two tools, viz., Analytic Hierarchy Process (AHP) and Simple Multi-Attribute Rating Technique Exploiting Ranks (SMARTER), are used to develop models for part type and family selection. The experimental results indicate that the performance of the proposed models are better than the common group scheduling heuristics under varied experimental conditions. / Singapore-MIT Alliance (SMA)

Využití metody FMS u atletů dorostenecké a juniorské kategorie / The use of methods of FMS in athletes of category U16 - U19

Sachová, Zuzana January 2017 (has links)
Title The use of methods FMS on athletes of category U16 - U19 Objectives: This thesis aims to point on the possibilities of a new method based on physio-therapeutic principles of physical preparation and training primarily of young athletes, named Functional movement screening (FMS), invented by Gray Cook. Most in particular the thesis is focused on what FMS method is and what possibilities are given to identify fundamental movement patterns of junior and teenager athletes. Short examination of the methods FMS was based on two tests invented by Gray Cook and evaluated on a group of ten athletes of category U16 - U19. Methods: The thesis comes out from two crucial works published by Gray Cook. Subsequently I resumed results found out in foreign articles and studies about methods FMS, its principles, relationship with athletic performance and prevention of injuries, as well as relevant norming data. My attention was devoted to studies focused on implementing FMS testing of young athletes. Therefore I decided to select two particular tests and conduct short testing on athletes of category U16 - U19. When scoring the quality of their movements, I've applied the criteria of the methodology itself first. Later there were extended by my own verbal evaluation of particular segments of tested movements. In...

No. of bitstreams: 1 6393.pdf: 3853954 bytes, checksum: aebabdd8a86520900d7239023c798d02 (MD5) Previous issue date: 2012-09-28 / Financiadora de Estudos e Projetos / The flexible manufacturing systems (FMS) are automated production systems capable of producing a wide variety of product types. They are composed by machines, robots and automated transport systems. Make the control of an FMS is a complex task due to the various subsystems and elements that compose it, and also by the necessity of respond to strategic issues that vary according to market demands. Much has been made in relation to the control of FMS. Several studies in the literature cover issues of control of FMS. Despite the high number of papers that address these issues, technological advances and market demands cause introduction of new challenges and new studies are conducted. This work based itself on other studies about the control of FMS to evolve into some issues of modeling and control of FMS. The purpose of this paper is to indicate a modeling strategy, based on Petri nets, that is easy to understand, requiring low efforts to adapt to different production plans, and allowing that the control of the FMS model takes into account information of the current state of the system in decision making for conflict resolution. The work ends with the application of the modeling method proposed in a hypothetical FMS. It was built a control system to make the reading of variables from the model of the FMS and decide how conflicts should be resolved on the Petri net model. To support the decision making of the control system, it was built a Fuzzy system. Simulations were conducted for a variety of production plans in which the control system achieved real-time responses to conflict resolution, preventing the system of reach deadlock conditions. / Os sistemas flexíveis de manufatura (FMS) são sistemas de produção automatizados capazes de produzir uma grande variedade de tipos de produto. Eles são compostos por máquinas, robôs e sistemas de transporte automático. Realizar o controle de um FMS é uma tarefa complexa devido aos vários subsistemas e elementos que o compõe, e também pela necessidade de responder a questões estratégicas que variam de acordo com as demandas do mercado. Muito tem sido feito em relação ao controle de FMSs. Vários trabalhos na literatura abrangem as questões de controle de FMSs. Apesar do alto número de trabalhos que abordam estas questões, os avanços tecnológicos e as exigências de mercado fazem com que novos desafios sejam lançados e novos estudos sejam realizados. Este trabalho se baseia em outros trabalhos sobre o controle de FMS para evoluir em algumas questões de modelagem e controle de FMSs. A proposta deste trabalho é indicar uma estratégia de modelagem baseada em redes de Petri que seja de fácil compreensão, que exija baixos esforços de adaptação para planos de produção diferentes, e que permita que o controle do modelo de FMS leve em consideração informações do estado corrente do sistema, nas tomadas de decisão para a resolução de conflitos. O trabalho é finalizado com a aplicação do método de modelagem proposto em um FMS hipotético. Foi construído um sistema de controle para fazer a leitura de variáveis do modelo de FMS e decidir como os conflitos do modelo em redes de Petri devem ser resolvidos. Para apoiar as tomadas de decisão do sistema de controle foi construído um sistema Fuzzy. Foram realizadas simulações para uma variedade de planos de produção nos quais o sistema de controle obteve respostas em tempo real para a resolução dos conflitos impedindo que o sistema atingisse condições de deadlock.

Foreign Military Sales trend analysis: impacts on the future with application to Taiwan

Moore, Kevin L., Ho, Chih-Haur, Foust, Coleen, Kerutis, Aidas 06 1900 (has links)
Approved for public release; distribution is unlimited. / MBA Professional Report / The purpose of this MBA Project is to investigate and provide an analysis of the prominent factors that affecr the United States Foreign Military Sales (FMS) program. This project was conducted with the sponsorship and assistance of the Naval Postgraduate School's Acquisition Research Institute, Financial Management and International programs. The overall goal of this project is three-fold: 1) to identify the purpose of the United States FMS program and its processes 2) to identify, define and evaluate historical economic, political, social and industrial changes and trends that affect FMS worldwide allocation and support and 3) to apply these findings to a specific country (Taiwan) to make a prediction of future participation and support. The role of arms sales in world politics has grown tremendously since the end of World War II and more specifically since the passage of new arms laws in 1979. The importance of FMS is increasingly evident in the foreign policies of both supplier and recipient nations, in international politics, competition and relations. Arms sales have become in recent years a crucial dimension of international affairs. This paper examines several trends in military equipment, services and training exchanges and investigates their potential impact on the future conflicts. The nature of FMS is complex. This research plans to identify and analyze trends relating to socio-political, economic, and industrial and technological changes associated with FMS spending. This discussion then applies these findings to Taiwan as a case study and expands on the customer's experience with FMS. The intent of this paper is to increase the reader's knowledge of FMS, pinpoint trends in the program and use FMS to Taiwan as a point of comparison to increase comprehension of this extremely complex and not well-understood program.

Developing and validating a school-based screening tool of Fundamental Movement Skills (FUNMOVES) using Rasch analysis

Eddy, Lucy, Preston, N., Mon-Williams, M., Bingham, Daniel D., Atkinson, J.M.C., Ellingham-Khan, M., Otteslev, A., Hill, L.J.B. 22 February 2023 (has links)
Yes / A large proportion of children are not able to perform age-appropriate fundamental movement skills (FMS). Thus, it is important to assess FMS so that children needing additional support can be identified in a timely fashion. There is great potential for universal screening of FMS in schools, but research has established that current assessment tools are not fit for purpose. To develop and validate the psychometric properties of a FMS assessment tool designed specifically to meet the demands of universal screening in schools. A working group consisting of academics from developmental psychology, public health and behavioural epidemiology developed an assessment tool (FUNMOVES) based on theory and prior evidence. Over three studies, 814 children aged 4 to 11 years were assessed in school using FUNMOVES. Rasch analysis was used to evaluate structural validity and modifications were then made to FUNMOVES activities after each study based on Rasch results and implementation fidelity. The initial Rasch analysis found numerous psychometric problems including multidimensionality, disordered thresholds, local dependency, and misfitting items. Study 2 showed a unidimensional measure, with acceptable internal consistency and no local dependency, but that did not fit the Rasch model. Performance on a jumping task was misfitting, and there were issues with disordered thresholds (for jumping, hopping and balance tasks). Study 3 revealed a unidimensional assessment tool with good fit to the Rasch model, and no further issues, once jumping and hopping scoring were modified. The finalised version of FUNMOVES (after three iterations) meets standards for accurate measurement, is free and able to assess a whole class in under an hour using resources available in schools. Thus FUNMOVES has the potential to allow schools to efficiently screen FMS to ensure that targeted support can be provided and disability barriers removed. / ESRC White Rose Doctoral Training Partnership Pathway Award (ES/P000745/ 1).
