Title: Analysis of the badminton matches in men's and women's singles The goals of essay: Main goal of the essay is to find out differences in first three shots and its most common combinations in single matches of men and women in relation to gaining a point during the rally. Another goal was to find frequency of using backhand and forehand hold in second and third shot. The last goal was to compare the frequency of ending in first, second and third shot between men and women. Methods: Indirect analysis - videoanalysis Results: According to results men and women primarily choose different types of serving. Men most often use short backhand serve, women high forehand serve. For the second shot men choose short shot or lob, women use smash. The third shot is lob in men rally, women choose short shot most often. Generally men uses in the first three shots shots less clears than women do. For both sexes are the most effective shots offensive ones, but men are more successful than women. The most effective direction of return was for men and for women the body of the player, in third shot it was the backhand side too (left middle and left back of the field). Men were more successful with forenhand, women with backhand. The frequenc of endings to third shots shows that women more often end the rally...

Title: Comparison of the badminton match in men's and women's singles Objectives: The goal is identify the most effective a choice combinations of the first three shots, leading to the acquisition point in singles between the best Czech male and female players. And also to discover determine and compare which was the usage of different types of serve, return and the third shots. Methods: Comparison of differences in badminton match between genders was based on indirect observation - video analysis. Statistics were used for data processing. Results: The results shower huge difference in tactical approaches among men and women players. Women preferred long high service and most of the service returns were played into back backhand court area and the third shot usually routed into back forehand court area. It means that the most played shot was a clear shot and the most occupied part of court was a back backhand corner. Despite more successful was when women players played drop by their third shot. Domination of short backhand service was seen by men players, the second shot routed the same direction like women players second shot - to the back backhand court, but also to the front part of the court. Third shot was mostly played into back backhand part of the court. If players wanted to be successful,...

The game of rugby has been played for over a century and yet its intricacies are still not fully understood. The key ingredient coaches are seeking is what can be added to a team’s make-up that will result in an increase in that teams level of playing success. The objective of this study is the exploration of the biomechanical aspects of movement in a rugby context specifically looking at the stages before, during and after contact. The hypothesis is that the optimal use of running lines in rugby union will lead to more successful breaches in the opposition’s defensive lines thus an increase in linebreaks will occur. In order to make a comparison based on scientific research principles, nine matches played during the 2001 season was compared with nine matches played during the 2002 season. For each match played in the 2001 and 2002 seasons the total number of linebreaks achieved in a match was calculated. In addition the total number of linebreaks achieved in the 2002 season was further subdivided into the specific categories of intervention in order to determine which intervention had the biggest impact on the total number of linebreaks achieved. By means of video footage of the matches played notational analysis was performed and information was gathered in order to gain data for further evaluation. The actions regarding the execution of the linebreaks were evaluated manually in respect of the intervention that was imposed during the coaching of the team during the 2002 season. Without exception a comparison between similar teams played during both seasons indicated that the total number of linebreaks achieved during the 2002 season was much higher than when the team competed against similar opposition during the 2001 season. The aggregate numbers indicated a significant increase in linebreaks from the 2001 to 2002 season. This conclusion was achieved by means of a simple T-test. Firstly an applied F-test test was done to determine whether the two samples had equal variances or not. Under the null hypothesis we assume that the variances of the two samples are equal, while the alternative states that the two samples have different variances. A value for the test statistic that is greater than the critical value will lead to a rejection of the null hypothesis. The test statistic was calculated and evaluated against the F (8,8) = 2.59 critical value on a 5% level of significance. The value of 15.921 is greater than the critical value of 2.95 and therefore the null hypothesis cannot be accepted, concluding that the two samples do not have equal variances. We then proceeded to test whether the 2002 average linebreaks are significantly higher than the average linebreaks achieved in the 2001 season. Under the null hypothesis the two sample averages are equal. Under the alternative, the 2002 average is higher than the 2001 average. In contrast to normal T-tests this specific test was a one-sided upper or right hand test due to the fact that we are testing whether the one average is greater and not equal to the other. Therefore, we would only reject the null hypothesis of equal sample averages if the test statistic were greater than the appropriate critical value. The calculated test statistic is 4.4827 and was evaluated against the t 0.05,9 = 1.833 critical value. Once again we cannot accept the null hypothesis. Therefore we can conclude that the average of the total linebreaks made during the 2002 season is statistically greater than the average of the total linebreaks made during the 2001 season. The results of this study therefore indicate that the new techniques incorporated into the coaching of the team in 2002 did positively influence the number of linebreaks when compared to the 2001 season. / Dissertation (MA (Human Movement Science))--University of Pretoria, 2005. / Biokinetics, Sport and Leisure Sciences / unrestricted

The goal of this study is to gain a better understanding of the factors that play a role in dominant collisions in rugby as well as the relative significance of dominant collisions as an indicator of success. By means of video footage of matches played during the 2003-2005 Super 12 competitions, notational analysis was performed and information was gathered in order to gain the relative data. The hypothesis stands that if a team is aware of the factors that lead to a dominant collision, are able to execute them in a match situation, that team should be more successful. The following key performance measurements were evaluated in order to indicate how each factor affected the level of success of a team. They are as follows: average total number of collisions for a try to be scored, average total number of forced missed tackles for a try to be scored, ratio of dominant collisions versus passes executed when a try is scored and average positive velocity change of dominant collisions resulting in a try being scored. In order to prove the hypotheses a k-sample case will be used. The samples are related, thus the data used is interval and ratio. Therefore, the test used will be the repeated measures ANOVA test, a special form of n-way analysis of variance. The statistical evaluation is the critical test value where the d.f values are as following: Key Measurement (3,8), Year Rating (2,8), Year Rating by Key Measurement (3,8). When comparing these with a statistical table for critical values of the F distribution for Ą = 0.05, the critical values are as following: (3,8): 4.07, (2,8): 4.46, and (3,8): 4.07. Thus, the statistical results are grounds for accepting all three null hypotheses and concluding that there is a statistical significance of at least 95% with an alpha of 0.05 between the means in all three instances. This shows that the data captured for the twelve teams for all tries scored by these teams over a period of three years and for the four key measurements, have a statistical significance of 95% for the readings respectively. After evaluation of the data and making use of regression analysis and multiple regressions in order to establish the correlation between log position and the four key measurements there can be no doubt that the teams that finished higher on the log did indeed perform better according to the identified key performance measurements. / Thesis (DPhil (Human Movement Science))--University of Pretoria, 2006. / Biokinetics, Sport and Leisure Sciences / unrestricted

Essa dissertação apresenta dois objetivos de trabalho (1) desenvolvimento e avaliação um programa computacional para análises técnico-táticas em combates de judô; (2) analisar as ações técnico-táticas utilizadas por atletas de judô de quatro classes de idade (pré-juvenil, juvenil, júnior e sênior), nas oito categorias de peso oficiais do Brasil (super-ligeiro até pesado) no sexo masculino e feminino, em dois níveis diferentes, a saber: (a) Circuito Paulistano e (b) Estadual de São Paulo. Nesta segunda parte, foram analisadas as variáveis: i) estrutura temporal do combate; ii) execução e orientação de golpes; iii) quantificação de pontuação; e iv) caracterização do tipo de pegada. Para verificação da objetividade do programa computacional, três experts realizaram 20 análises de combate, sendo que um deles analisou as mesmas 20 por três vezes (1° expert, n= 20; 2° expert n= 20, e; 3° expert n= 60). Para a comparação entre grupos observados no segundo estudo e para verificar a correlação de concordância (CCC) entre as medidas dos experts, utilizou-se a Análise de Variância e, quando necessário, post hoc de Tukey, com nível de significância adotado de 5%. Os resultados quanto ao programa demonstraram forte correlação intra e inter-expert, com alto grau de concordância (> 0,90 de índice) para 41 grupos de variáveis e (>0,80 de índice) para 37 grupos de variáveis, respectivamente. Para o segundo estudo, os principais resultados para o sexo masculino foram: no nível estadual e/ou a classe sênior, utilizam maiores tempos de combate, de luta em pé (tachi-waza) de movimentação livre, de pegada e da variação de pegada e direção de ataque. Nos grupos do sexo feminino, ocorreram diferenças entre o nível estadual e/ou a classe sênior (exceto quando comparado à classe pré-juvenil no tempo de combate sem pausa e no tempo de pegada) e os demais grupos - com tempos maiores para combate, tachi-waza, movimentação livre e pegada -, demonstraram diferenças entre a categoria pesado - que possuiu tempos de combate, tachi-waza, movimentação livre e pegada menores do que as categorias meio-leve, leve e meio-médio. Quanto às diferenças entre níveis, as atletas do estadual apresentaram uma frequência maior de entradas de golpe e de quantidade de tipos de pegada utilizados / This dissertation has two goals: developing and evaluating a computer program for the analysis of technical and tactical combat in judo, and analyzing technical-tactical actions used by judo athletes from four age classes (pre-juvenile, juvenile, junior and senior) in the eight official Brazilian weight categories (super-light to heavy), males and female, at two different levels, namely: (1) São Paulo City (Paulistano) and (2) São Paulo State levels. The variables were: i) temporal fight structure, ii) execution and direction of throws, iii) quantification of scores and iv) characterization of grip type. In order to verify the objectivity of the computer program, three experts conducted 20 analyses of combats, with one expert examining three times the same 20 (1st. expert, n = 20; 2nd. expert n = 20; 3rd. expert n = 60). For comparison between groups observed in the second study and in order to verify the concordance correlation (CCC) between experts measurements, analysis of variance and, when necessary, post hoc Tukey test with significance level p <0.05, were used. The results from the software showed strong intra and inter-expert agreement, with higher rate (> 0,90 of index) in 41 groups of variables and (>0,80 of index) in 37 groups of variables, respectively. For the second study, the most significant results from the male group were at the state and/or the senior class, using longer periods of combat, standing fight (tachi-waza), free displacement, grip time and variation in grip type, and direction of attacks. In females, there were differences between state and/or the senior class (except when compared to pre-juvenile in fight time without pause and grip time) and other groups, with more combat time, tachi-waza, free displacement and grip - showing differences between the heavyweight, who presented less combat, tachi-waza, free movement and grip times, and half-lightweight, lightweight and welterweight categories. Regarding differences between levels, state-level athletes used a higher frequency of techniques and different grip types

Con el fin de mejorar el entrenamiento de aquellos aspectos técnicos y tácticos que contribuyen al rendimiento deportivo se planteó esta tesis doctoral. Su objetivo general fue describir las diferencias técnico y tácticas entre ganadores y perdedores en rugby internacional masculino. Para responder a ello se plantearon cuatro estudios basados en la metodología observacional, cubriendo un gran espectro de herramientas propias de esta metodología. De forma general los resultados más importantes han encontrado diferencias a favor de los ganadores en: las fases de conquista del balón, fases de lanzamiento; y en la utilización del balón. Los perdedores muestran mayor cantidad de fases dinámicas y de reagrupamiento. Estas diferencias se dan en al análisis colectivo e individual. / To this end and in order to improve the training of technical and tactical aspects that contribute to athletic performance raised this dissertation. Its overall objective was to describe the technical and tactical differences between winners and losers in international rugby men. To answer this basis of four studies based on observational methodology, covering a wide spectrum of tools of this methodology. In general the results the most important results have found differences in favor of the winners: the phases of conquest of the ball, launch stages, and the use of the ball. The losers showed most dynamic phase of reunification, These differences occur in the collective and individual analysis.

Cricket umpiring is demanding. In today’s world where so much technology is available to television viewers, they expect perfect umpiring, forgetting that what they see on their television screens is not available to the umpires standing in the middle of the field making the decisions. This study aimed to examine cricket umpires on-field decisions during the 2007 ICC Cricket World Cup. Examining leg before wicket (LBW) and caught behind decisions, in particular. The researcher made use of a notational analysis program known as Umpirestat to collect the necessary data on each umpire. The umpires were examined in two groups Elite and International umpires (groupings defined by the ICC) and were compared to a base line in the form of Hawk-Eye for LBW decisions and TV replays for caught behind decisions. The umpire groups were compared to each other and then to the base line, an individual umpire comparison was then done within each grouping. The data was statistically analysed using percentages, chi squared and modelling for the Elite Umpires. For LBW decisions there was a difference of 2.02% between Elite and International umpires, showing a similarity between the two groups. The difference between Elite Umpires and Hawk-Eye was 18.83% and between International umpires and Hawk-Eye was 16.81%, showing difference between the three groups. It was found that there was a difference of 3.63% for caught behind decisions between Elite and International umpires, showing a similarity between the two groups. The difference between Elite Umpires and TV replays was 2.99% and between International umpires and TV replays there was 0.64%, showing similarities between the three groups. In conclusion, for LBW appeals there is a similarity between Elite and International umpire groupings however a difference exists between Hawk-Eye and both groupings of umpires. For the individual umpires LBW comparison the following was seen for the International umpires; no real conclusions could be drawn due to limited amounts of data collected on them. However, variances in individual performances were seen within the International umpire grouping. For Elite Umpires, it is clearly seen in the model that the umpires expected number of dismissals got closer together and almost group together at around four appeals. This indicates a strong consensus amongst umpires when dealing with four, five and six appeals during a match. This consensus is more pronounced for four and five appeals. In conclusion, for caught behind appeals there is a similarity between Elite and International umpires as well as a similarity between replays and both groups of umpires. For the individual umpires caught behind comparison the following was seen for the International umpires; as with the LBW results there was limited amount of data available for the caught behind results. Thus no real conclusions could be drawn for International umpire caught behind decisions, although when examining the percentage data, differences can be seen. For the individual umpires caught behind comparison the following was seen for the Elite Umpires, no consensus is seen between the umpires - they all appear to have different expected dismissals to one another.

Durch die räumliche Anordnung von Symbolen stellt die Notenschrift zeitliche Verläufe dar. Sie ermöglicht dadurch, die Ordnung dessen, was in der Zeit abläuft, nicht nur überblicken, sondern auch manipulieren zu können. Es wäre also anzunehmen, dass diese bildliche Eigenschaft der Schrift, die das Nacheinander in der Zeit zu einem Nebeneinander im Raum werden lässt, gerade bei komplexen Tempostrukturen zu Übersichtlichkeit und Verständlichkeit beiträgt und so ein operatives Potenzial entfaltet. Tatsächlich ist die Partiturdarstellung von tempopolyphoner Musik aber oft eine grafische Herausforderung. Die Festlegung der räumlichen Anordnung der Symbole ist bei der Gleichzeitigkeit verschiedener Tempi nicht trivial und oft mit einem erheblichen (rechnerischen) Mehraufwand verbunden. Dieser Beitrag möchte, unter Bezugnahme auf den aktuellen Diskurs zur Schriftbildlichkeit, Überlegungen dazu anstellen, wie die Notenschrift beim Komponieren von tempopolyphoner Musik ihre Funktion als Denk- und Handlungsraum entfaltet. Dazu werden Erkenntnisse aus einem laufenden Forschungsprojekt beigezogen, die sich auf Beobachtungen, Analysen und Interviews mit den beteiligten Komponist*innen stützen. / Musical notation represents the progress of time through the spatial arrangement of symbols. It thus provides not only an overview of the temporal arrangement of events but also the possibility to manipulate it. One would therefore assume that this graphical property of musical notation, which turns the succession in time into a juxtaposition in space, would contribute to clarity and comprehensibility, especially in complex tempo structures, and thus develop an operative potential. In reality, however, the representation of polytempic music in a score often presents a graphical challenge. Determining the symbols’ positions is not trivial when different tempos are played simultaneously, often requiring considerable additional (mathematical) effort. Regarding the current discourse on ‘notational iconicity’, this article reflects on how when composing polytempic music, notation unfolds its function as a space for thinking and acting. For this purpose, the author refers to findings from an ongoing research project, based on observations, analyses and interviews with the involved composers.
