Athletes can be exposed to verbal and mental abuse from their coaches, which can include behaviours such as belittling, humiliation, and psychological stress. This issue is exacerbated by the contention that exists within the literature on how to define verbally and mentally abusive coaching behaviours. The goal of this research is to explore coaches’ personal definitions and views on verbal and mental abuse and ways to address it within the community of elite female volleyball in Manitoba. This qualitative research study triangulates auto-ethnography, semi-structured interviews, and content analysis of both coaching education and policy text sources in force in Manitoba to explore the complexities of verbal and mental abuse in elite sport. This study analyzes consistencies and inconsistencies between the views of elite coaches, coach education text sources and coaching policies, and provides recommendations for addressing verbal and mental abuse in the context of elite female volleyball in Manitoba. / February 2016

Hoje a preocupação quanto às lesões que acometem os atletas de alto rendimento no esporte tem sido motivo de grande investigação e discussão científica. O presente estudo teve como objetivo conhecer e identificar os fatores de risco que colaboraram para as lesões músculoesqueléticas de cinco atletas da modalidade voleibol em uma equipe de alto rendimento, durante duas temporadas de competição. A pesquisa caracteriza-se como estudo de casos, que utilizou como instrumentos de investigação: entrevista, questionário de lesão, registro de dado (planilhas de treinamento), análise documental (prontuários). Os resultados da investigação foram categorizados demonstrando que as cinco atletas foram submetidas ao treinamento de mais de uma categoria durante a fase de formação esportiva e a precocidade no treinamento com equipe adulta, durante as temporadas de 2001/2002 e 2002/2003. As lesões que ocorreram em maior quantidade foram as por sobrecarga e o tempo de afastamento para resolução ou melhora da dor ou da lesão não eram priorizados. A maior parte das lesões ocorreram durante os treinos e o membro inferior foi o mais acometido. / Nowadays the concern related to the injuries that affect the high performance athletes in sports has been the reason of great inquiry and scientific discussion. The present study had as its objective to know and identify the risk factors that contributed to the rawboned muscles injuries of five athlete of the volleyball events in a high performance team, during two seasons of competition. The investigation is characterized as a study cases, that used as research instruments: interview, questionnaire of injury, register of data (training spread sheets), documentary analysis (handbooks). The results of the investigation had been categorized demonstrating that the five athletes had been submitted to the training of more than a category during the sporting formation phase and the precocity in the training with adult team, during the seasons of 2001/2002 and 2002/2003. The injuries that had occurred in bigger amount were the overload ones, and the removal time for resolution or improvement of the pain or injury were not prioritized. Most injuries had occurred during the training and the low member was more affected.

O presente estudo teve como objetivo, estabelecer o modelo da estrutura do desempenho esportivo por meio das adaptações antropométricas e motoras de atletas de equipe de voleibol masculino, adotando o ciclo de preparação da Seleção Brasileira Sub-19 para o Campeonato Mundial, no ano de 2005. A amostra foi intencional e composta por 12 atletas, com média de idade de 17,76+0,71 anos. Para o volume de treinamento, foi adotada a análise documental a partir de manuscritos elaborados pela comissão técnica. As variáveis analisadas nas três avaliações foram organizadas na seguinte ordem: Carga horária de treinamento; Antropométricas (estatura, massa corporal, somatória de sete dobras cutâneas, percentual de gordura); Potência de membros superiores (arremesso de “medicine ball” com três quilogramas); Potência de membros inferiores (saltos contramovimentos, “squat jump”, altura de alcance de salto de ataque e bloqueio, impulsão de saltos de ataque e bloqueio); Agilidade e resistência de velocidade (deslocamentos em 30m e 78m); Resistência muscular localizada (abdominais 30 segundos). Para verificar a influência do tempo de treinamento nas adaptações do desempenho foi utilizado o Modelo Linear Geral de Medidas Repetidas; para analisar e explicar a correlação entre as variáveis foi utilizada a Análise Fatorial das Componentes Principais. Os resultados encontrados permitem estabelecer as seguintes distribuições do volume de treinamento das categorias: treinamento físico: 94,92 horas (31,35%), treinamento técnico: 79,83 horas (36,32%), treinamento tático: 125,72 horas (41,53%) e o treinamento psicológico apenas 2,25 horas (0,74%). Em relação às variáveis e a influência do fator “treinamento”, na mudança das médias, identificamos valores com poder de observação superior a 99,9% para as variáveis estatura (F=93,15, p=0,000) e agilidade (F=26,08, p=0,000); 98,9% alcance de ataque (F=14,60, p=0,000); 97,4% resistência de velocidade (F=12,50, p=0,002); 96,3 % alcance de bloqueio (F=11,54, p=0,003); 91,1% impulsão de bloqueio (F=9,06, p=0,006); 89,7 % massa corporal (F=8,64, p=0,007); 86,3% resistência muscular localizada (F=7,79, p=0,009); 58,8% impulsão de ataque (F=4,12, p=0,050); 54,7% envergadura de bloqueio (F=3,75, p=0,061). O modelo das componentes principais produziu uma explicação da variabilidade total em cada avaliação (92,15% na primeira avaliação, 91,22% na segunda avaliação e 85,95% na última avaliação). O tempo destinado à duração das sessões de treinamento e a quantificação das categorias física e técnica demonstraram maior volume no período preparatório, com a finalidade de adaptar o organismo dos atletas para cargas mais intensas, conforme a aproximação do período competitivo. As adaptações durante a preparação demonstraram diferenças significativas e elevado poder de influência do treinamento nas variáveis antropométricas e motoras. O modelo do desempenho esportivo estabelece, com elevado percentual de variância nos três momentos de avaliação, a primeira componente (estatura e envergaduras de ataque e bloqueio), massa corporal e saltos específicos (alcance de ataque e bloqueio). Ao ser identificada a inter-relação entre as variáveis descritas, torna-se mais evidente a necessidade de se destinar maior atenção para os atletas mais altos, e consequentemente mais fortes. / This study had as objective to determine the structure of sport performance through the anthropometric and biomotor adaptations on the athletes from the male volleyball team during the macrocycle of under-19 Brazillian National Team in preparation to the 2005 world championship. The sample was composed of 12 athletes (17.76±0.71 years old). Training volume analysis was according to the manuscripts recorded by the coaches. The athletes were tested in three different moments and the measured variables were organized as followed: Training volume quantification; anthropometry (height, body mass, sum of seven skinfolds, % body fat); muscle power of the upper extremities ( 3 kg medicine ball throwing ); muscle power or the lower extremities ( squat jump. countermovement jump, attack and block height, attack and block vertical jumping height); shuttle test for agility ( 30 m) and shuttle test for speed resistance (78 m); abdominal strength (situps 30 s). The linear model for repeated measures was used to verify the influence of training time exposure on the adaptations on the performance; the factorial analysis of the mean components was used to analyze and explain the correlations among the variables. The results presented the following distribution for training volume: physical conditioning (94.92 hours – 31.35%); technical practices (79.83 hours – 36.32%), tactical training (125.72 hours – 41.53%) and psychological training (2.25 hours – 0.74%). Related to the measured variables and the influence of the training in the mean changes, it was identified values with observational power superior to 99.9% to the variables height (F=93.15, p=0.000) and shuttle test for agility (F=26.08, p=0.000); 98,9% attack height (F=14.60, p=0.000); 97,4% shuttle test for speed resistance (F=12.50, p=0.002); 96,3 % block height (F=11.54, p=0.003); 91,1% block vertical jump (F=9.06, p=0.006); 89,7% body mass (F=8.64, p=0.007); 86,3% abdominal strength (F=7.79, p=0.009); 58.8% attack vertical jump (F=4.12, p=0.050); 54,7% standing block height (F=3.75, p=0.061). The model of the principal components presented results that explained the total variability on each testing moment (92.15% moment 1; 91.22% moment 2; 85.95% moment 3). The time spent on training sessions and the quantification of the categories physical conditioning and technical practices demonstrated a highest volume at the preparatory period which aimed to promote adaptation on the athletes´ organism in order to prepare them to more intense work loads in direction to the competitive period. The adaptations occurred during the preparation revealed significant differences and high power of training volume influence in the anthropometric and biomotors variables. The model of sport performance demonstrated high percentage of variance at the three distinct testing moments, the first component (height and standing height for attack and block), body mass and specific jump tests (attack and block height). When identifying the inter-relation among the described variables, it is important to highlight the need to carefully deal with the tallest and consequently the strongest athletes.

Cette étude a eu comme objectif l´analyse de les facteurs déterminants de la dynamique fonctionnelle du jeu de Volley-ball Masculin, en ce qui regarde le KI, au haut-niveau compétitif. Pour l'étude ont été considérées des variables adjointes à la dimension interne du jeu, relatives aux dimensions espace, temps, tâche, joueur et performance et au niveau compétitif des équipes, déterminé par le rangement de la compétition. 1698 séquences offensives ont été analyses dès le service adversaire, qui ont été réduites à 1486 pendant la réception, à 1363 pendant da distribution et à 1344 pendant l'attaque et le bloc, obtenues de 19 jeux des équipes Nationales meilleures placées au Championnat Mondial de Volley-ball Masculin de 2006. La collection de données a été obtenue par de moyens audiovisuels. L'instrument d'observation utilisé a été en obéissant aux critères de validation de construction et de contenu. L'analyse des données a inclue la statistique descriptive, par l'obtention de fréquences et de pourcentages. II a aussi été utilisé statistique déductive à travers de la régression logistique multinomial, avec le but de mesurer le possible effet prédictif des variables indépendantes sur la variable dépendante. La fiabilité intra et inter-observateur a été assurée par le recours à l'index Kappa de Cohen. Les resultats de cette étude ont montré la pratique d'un jeu hautement qualifié au KI, configuré par des actions d'excellente qualité, dès la réception jusqu'à la fin de l'attaque, ce que a produit, par conséquence, des conditions désavantageuses pour le bloc adversaire. Les résultats ont démontré que la dynamique fonctionnelle du KI est relativement stable et déterministe. Par contre, le niveau d'interférence de l'adversaire a influencé le pouvoir prédictif des dimensions d'analyse, puisque l'effet de l'attaque a été moins déterminé que l'effet de la réception, en conséquence de l'interaction élevée entre attaqueur et adversaire. La dynamique fonctionnelle du KI a démontré être déterminée par le service et, à son tour, a exercé pouvoir prédictif sur le bloc. Les équipes de niveau compétitif différent ont montré de caractéristiques distinctes au niveau de la dynamique fonctionnelle du KI et des variables adjointes au KII, en prouvant que le rangement obtenu au Championnat a distingué la qualité du jeu pratiqué. / Este estudo teve como objetivo examinar possíveis determinantes da dinâmica funcional do jogo de Voleibol Masculino, ao nível do Complexo I, no alto rendimento competitivo. Para o estudo foram consideradas variáveis adstritas à dimensão interna do jogo, relativas às dimensões espaço, tempo, tarefa, jogador e desempenho e o nível de rendimento competitivo das equipes, determinado pela classificação na competição, em estudo. Foram analisadas 1698 seqüências ofensivas a partir do saque adversário, sendo que se reduzem para 1486 durante a recepção, 1363 na ação de levantamento e para 1344 na ação do ataque e de bloqueio, retiradas de 19 jogos entre as dez Seleções Nacionais melhores classificadas no Campeonato Mundial de Voleibol Masculino de 2006. A coleta de dados foi garantida pelo sistema de vídeo. O instrumento de observação utilizado foi testado, obedecendo aos critérios de validação de construção e de conteúdo. A análise de dados comportou a estatística descritiva, pela obtenção de freqüências e percentagens, e a estatística inferencial pelo recurso à regressão logística multinomial, no sentido de medir o possível efeito preditor de variáveis independentes sobre uma variável dependente. As fiabilidades intra e interobservador foram apuradas através do recurso ao índice Kappa de Cohen. Os resultados decorrentes da amostra estudada evidenciaram a prática de um jogo altamente qualificado no Complexo I, configurado por ações de excelente qualidade desde a recepção até a finalização do ataque, o que gerou, conseqüentemente, condições desvantajosas para o bloqueio adversário. Os resultados evidenciaram que a dinâmica funcional do Complexo I é relativamente estável e determinista. Todavia, o nível de interferência do adversário influenciou o poder preditor das dimensões de análise, uma vez que o efeito do ataque foi menos determinado do que o efeito da recepção, em razão da elevada interação entre atacante e oponente. A dinâmica funcional do Complexo I mostrou ser determinada pelo saque e, por sua vez, exerceu poder preditor sobre o bloqueio. As equipes de nível de rendimento competitivo distinto evidenciaram características diferenciadas na dinâmica funcional do Complexo I e nas variáveis adstritas ao Complexo II, evidenciando que a classificação obtida no Campeonato diferenciou a qualidade do jogo praticado. / The purpose of this study was to examine possible determinants on the functional dynamics of high level men's Volleyball, in complex I. Hence, variables related to the internal dimension of the game were considered, regarding the dimensions of space, time, task, player, and performance, allied to the team's competitive level (determined by the ranking within the analyzed competition). A total of 1698 sequences from the opponent's serve were analyzed. From these, 1486 allowed serve reception, 1363 allowed setting, and 1344 culminated in attack and blocking actions. These sequences were retrieved from 19 matches between the ten best National Teams, according to their classification on the 2006 Men's World Championships. Data was recorded in video support. The observation instrument was previously tested, following criteria for construction and content validation. Data analysis consisted in descriptive statistics (frequencies and percentages), and inferential statistics, namely multinomial logistic regression, with the purpose of measuring the predictive effect of independent variables upon a dependent variable. Intra- and inter-observer reliability was assessed with Cohen's Kappa. Our sample revealed a highly effective game in Complex I, configured by actions of excellent quality, from serve reception to the attack, consequently generating disadvantageous situations for the opponent's block. Results evidenced that the functional dynamics of Complex I are relatively stable and deterministic. However, the opponent's interference level has influenced the predictive power of the analysis dimensions since the attack effect was less determinant than the reception effect, due to the high interaction between attacker and opponent. The functional dynamics of Complex I are strongly determined by the serve, which, in turn, had predictive power over the blocking action. Teams from distinct performance levels have evidenced different characteristics within the functional dynamics of Complex I and related features of Complex II. Hence, the Championship's final ranking allowed differentiating the quality of the practiced game.

Thesis title: Electromyographic Analysis of the Shoulder Girdle Muscles Inclusion of Volleyball Players Problem definition: Elite sport is very demanding, not only physically, but also mentally. The demands on the musculoskeletal system are often not compensated, especially in children and junior categories. The only targeted and regular compensation takes place at volleyball by the fitness training in the gym, but not always properly lead and adapted to the individual needs of athletes. The question is whether it is possible to prevent these problems. From my perspective, yes, the inclusion of appropriate compensation exercise in normal training session, which will require little equipment and time and to be functionally connected with volleyball technique that players do not lose the game performance. In the context of the thesis will be compared exercising of the second diagonal PNF for the upper extremity with an elastic resistance and simulated strike without the ball - volley lob, as an alternative fitness of exercises for volleyball players. Objectives: The aim of the dissertation is based on the available literature to outline the issues of kinesiological and biomechanical relationships of the shoulder girdle in sports especially in volleyball, which is a typical representative of the...
