Esta dissertação parte da premissa de que o desalinhamento dos arcos plantares estão associados ao mal funcionamento do pé e a subseqüentes desequilíbrios mecânicos gerados por compensações na cadeia cinética e articulações adjacentes. A bandagem plantar é uma das técnicas comumente utilizadas no tratamento e prevenção de lesões decorrentes destes desalinhamentos; no entanto, sua eficácia no controle postural ainda é incerta. Nossas hipóteses são: (i) que sujeitos com arco rebaixado apresentariam déficits do controle postural que se acentuariam em condições de perturbação sensorial, e (ii) que a bandagem aplicada no médio-­pé para melhorar a acuidade sensorial traria benefícios para o controle postural destes sujeitos, principalmente nas condições de perturbação. Assim, apresentaremos nesta dissertação dois estudos, um para investigar as alterações no controle postural de indivíduos com rebaixamento do arco plantar (estudo 1), e outro para investigar as consequências da utilização bandagem plantar nestes indivíduos (estudo 2). Para ambos os estudos, avaliamos a velocidade média e o root mean square da trajetória do centro de pressão durante a manutenção da postura quasi-­-estática em quatro condições de perturbação sensorial: (1) plataforma fixa, olhos abertos; (2) plataforma fixa, olhos fechados; (3) plataforma móvel, olhos abertos; e (4) plataforma móvel, olhos fechados. No estudo 1, 24 mulheres com arcos normais foram comparadas a 13 mulheres com arco rebaixado. No estudo 2, a comparação foi feita entre as condições sem e com a bandagem plantar para as 13 mulheres com arco rebaixado. Os resultados indicam que mulheres com rebaixamento do arco oscilam menos e mais lentamente que mulheres com arco normal, em particular na condição de maior perturbação sensorial, o que pode representar uma resposta pior, ou mais lenta de um sistema com desequilíbrios mecânicos decorrentes de um pé pouco funcional. Já a utilização da bandagem plantar resultou em aumento da oscilação do centro de pressão para a maioria das condições de perturbação sensorial, principalmente na direção médio-­-lateral, o que pode ser explicado por uma dificuldade dos sujeitos em se ajustar a uma nova postura, ou indicar um ganho de confiança e um melhor funcionamento do pé, traduzido pelo aumento da utilização dos ajustes posturais. / This dissertation is based on the premise that misalignment of plantar arches are associated to poor foot function and to subsequent mechanical compensations in the kinetic chain and adjacent joints. Foot taping is a commonly used technique in the treatment and prevention of injuries caused by these misalignments; however, its efficacy on postural control is still uncertain. Our hypotheses are: (i) subjects with low plantar arch would present postural control deficits, detectable by center of pressure sway measurement, that would be worsened in conditions of sensory perturbation, and (ii) foot taping, applied on midfoot with the intention to improve the cutaneous sensorial acuity, would bring benefits to the postural control of these subjects, especially under conditions of sensory perturbation. Thus, two studies will be presented: the first meant to investigate postural control alterations in individuals with low plantar arch (study 1), and the second, to investigate the effects of foot taping use in these subjects (study 2). For both studies, the mean velocity and root mean square of center of pressure trajectory were assessed during the maintenance of quasi-static stance in four conditions of sensory perturbations: (1) fixed support, eyes opened; (2) fixed support, eyes closed; (3) moving support, eyes opened, and (4) moving support, eyes closed. In study 1, 24 women with normal plantar arch were compared to 13 with low plantar arch. For study 2, the same 13 low arched subjects were assessed with and without foot taping. Results indicate that women with low plantar arch have less and slower center of pressure sway, particularly in the condition of highest sensory perturbation level, which may indicate a worsened, or slower, response of a mechanically altered system. When foot taping was applied to the low arched individuals, a higher and faster center of pressure sway was observed in most of the sensory perturbation conditions, especially in the medio-lateral direction. This could be explained either by a difficulty for the subjects to adapt to a new imposed postural condition, or by a gain in confidence while using the taping, reflected by the increase in postural adjustments.

Caracterizado por incorporar estilos de luta derivados de outras artes marciais, envolve técnicas de agarre em pé, agarre no chão, técnicas de percussão em pé e exige nível de condicionamento físico elevado. De modo frequente, a prática de modalidades esportivas de combate envolve a própria luta como método de treinamento físico e técnico e parece apresentar alta relevância, visto que é frequente o estudo de lutas simuladas em diversas modalidades de combate. Com isto, torna-se relevante o conhecimento das características destas práticas de treinamento, visto que, já foi evidenciado que lutas simuladas apresentam respostas diferenciadas de combates em eventos oficiais. Neste sentido, a relação entre esforço e pausa das lutas tem sido fortemente sugerida como método para prescrição de treinamento, o que aponta a necessidade do conhecimento destas variáveis em lutas simuladas. Adicionalmente, o conhecimento do estresse físico, orgânico e percebido dos atletas, a partir destes estímulos, se torna necessário para melhor adequação do processo de planejamento e organização. Deste modo, a redução dos fatores empíricos de prescrição pode promover maior previsibilidade das adaptações e reduzir os riscos de overtraining, já que esta realidade deve ser fortemente considerada no MMA. Assim, considerando que grande parte do entendimento acerca do MMA é advinda das modalidades que o compõem, torna-se relevante a descrição das demandas orgânicas, físicas e psicométricas originadas especificamente da simulação de lutas de MMA e as relações destes com a temporalidade das lutas, bem como a caracterização dos processos recuperativos de indicadores do dano muscular advindo desta prática. / Among the different types of fighting, Mixed Martial Arts (MMA) has grown rapidly in the international scenario. Characterized by incorporating fighting styles derived from other martial arts techniques involves standing grappling, groundwork grappling percussion techniques and require high fitness level. So often, the practice of sports of combat involves his own struggle as a method of physical and technical training and introduce high relevance, since it is often the study of simulated fights in various modes of combat. With this, it becomes relevant knowledge of the characteristics of these training practices, as has been evidenced that simulated fights have differentiated responses of fighting in official events. In this sense, the relationship between effort and pause of the fighting has been strongly suggested as a method for training prescription, what points the need of knowledge of these variables in simulated fights. Additionally, the knowledge of physical stress, organic and noticed the athletes, from these stimuli, it is necessary to better matching of the planning process and organization. Thus, the reduction of empirical factors of prescription can promote greater predictability of adaptations and reduce risks of overtraining, as this reality should be strongly considered in MMA. Thus, whereas much of the understanding of MMA is from the modalities comprising it, becomes relevant to description of organic, physical demands and psychometric originated specifically MMA fights simulation and the relationships of these with the temporality of the fights, as well as the characterization of the recovery processes of muscle damage indicators from this practice.

Name: Individual performance development of young female heptathletes Objectives: The aim of this study was to evaluate and judge performance development of young female czech heptathletes aged between 16 and 19 years old. From the analysis their personal performance development and other factors that may affect their performance we want to find out which of them have the best assumptions to succeed in athletic heptathlon. Methods: The work was a qualitative research. Specifically, it was a case study. We collected data through document analysis methods. We evaluated performance development of each selected athlete. We used the comparison method to compare the performance development of each athlete considering to other heptathletes and Eliška Klučinová. Using a semi-structured interview we researched another information about their training and social, psychological, health and somatic assumption, which may affect their further performance growth.

The questionnaires were sent by email, the information was processed in Microsoft Excel. An informal personal interviews were conducted in order to create an overview of the subjects for the training of selected athletic disciplines. During these informal...

College students between the ages of 18 and 24 are considered high-risk for alcohol-related negative consequences due to drinking at high-risk levels (Barry, Howell & Salaga, 2015). Within that population, varsity student athletes are considered at even greater risk for those issues (Druckman, 2015; Wechsler, 2002). With football and men’s basketball being considered the only revenue-generating NCAA Division I sports, non-revenue-generating sports consist of the majority of student athletes (NCAA, 2016). This study is designed to examine high-risk drinking as well as alcohol-related consequences among non-revenue-generating student athletes attending a National Collegiate Athletic Association (NCAA) Division I school. The sample population for this study attends a large, Power 5 Conference, NCAA Division I institution located in the United States. Of the sample, there are 228 respondents representing the majority of non-revenue-generating sports and nearly 68% of the total population of student athletes who participated in non-revenue-generating sports. Utilizing the Athletic Identification Measurement Scale (AIMS), the Identification of Psychological Group scale (IDPG), and the Harvard College Alcohol Study (Wechsler, 2002), this study identifies factors that may associate with high-risk drinking and alcohol-related consequences set within the framework of the Social Ecological Model of Prevention (Brewer Van Raalte & Linder, 1993). Through descriptive statistics and basic correlation methods, the study examines the role of factors in four of the five levels of the Social Ecological Model of Prevention (individual, relationship, organizational, and community—public policy is not used for this study) as compared to high-risk drinking and alcohol-related negative consequences. The findings of this study indicate that this population experiences negative consequences in greater volume than respondents to the College Alcohol Study (Wecshler, 2002) and the NCAA Alcohol Study (2014), which may imply that non-revenue-generating student athletes are at a higher risk than revenue-generating athletes. Additionally, teams with the most dissonance regarding the team alcohol policy are more likely to experience alcohol-related negative consequences. Teams that are consistent in their understanding of the team alcohol policy experience fewer alcohol-related negative consequences, regardless of the overall levels of high-risk drinking.

Concussion rates and head injuries for football players have been on the rise and there is a need for further research in football to increase skills and decrease injuries. Behavioral skills training has been proven to be effective in teaching a wide variety of skills but has yet to be studied in the sports setting. We evaluated behavioral skills training to teach safer tackling techniques among six participants from a local Pop Warner football team. Results show safer tackling techniques increased substantially during practice and generalized to games among all six participants.

Cette thèse a pour objet à partir d'une approche sociologique d'évaluer qualitativement la cohésion globale d'une équipe de football amateur en tenant compte des principaux acteurs que sont les joueurs, l'entraîneur et le président du club d'une part et d'analyser les liens entre la cohésion de groupe et les résultats sportifs d'autre part. La question est donc de savoir dans quelle mesure les interactions entre les membres d'une équipe de football amateur tant sur le terrain de jeu qu'en dehors peuvent-elles refléter le niveau de cohésion globale de l'organisation .Il s'agit d'expliquer à partir de l'analyse stratégique et systémique de Crozier et Friedberg (1977), comment ces acteurs aux objectifs personnels différents, voire même opposés réussissent-ils à coopérer pour atteindre l'objectif sportif fixé par le groupe. C'est en d'autres termes chercher à comprendre comment malgré leurs ressources et contraintes inégales, les diverses stratégies d'acteurs, les membres d'une équipe arrivent-ils à collaborer. Trois équipes seniors des clubs du Rhône ont été retenues dans cette étude : il s'agit de Grigny FC, l'AS Bron Grand Lyon et l'US Millery Vourles. Les principaux résultats de ces enquêtes montrent que : l'entraîneur et surtout le président peuvent autant influencer la cohésion d'équipe que les joueurs ; que les résultats sportifs d'une équipe de football amateur sont fonction non seulement du degré de cohésion globale de ses membres, mais aussi de la prise en compte des aléas sportifs ; que la notion d'amateurisme varie d'un club à un autre en fonction de certains paramètres parmi lesquels la distribution ou non de l'argent aux joueurs occupe une place de choix. Ces études concluent donc que la cohésion globale des membres d'une équipe de football amateur peut s'évaluer qualitativement et influence effectivement ses résultats sportifs / This thesis aims from a sociological approach to assess qualitatively the overall cohesion of a team of amateur football taking into account the main actors are the players, the coach and the club president on the one hand and analyze the relationship between group cohesion and sports scores on the other. The question is to what extent the interactions between members of a team of amateur football as the playground and outside can they reflect the level of overall cohesion of the organization. This is explained from the strategic and systemic analysis of Crozier and Friedberg (1977), how these actors at different personal goals, even opposite successful are to cooperate to achieve the goal set by the sports group. It is in other words trying to understand how despite their resources, unequal stresses, and various stakeholder strategies, the team members come to work. Three senior teams clubs of Rhone were included in this study: it is Grigny Football Club, the Athletic Association of Greater Lyon Bron and Union Sportive of Millery Vourles. The main results of these investigations show that: the coach and especially the president can all influence teams cohesion as players; the sports results of a team of amateur football depends not only on the degree of overall cohesion of its members, but also taking into account the vagaries of sport; These studies conclude that the overall cohesion of the members of a team of amateur football can be evaluated qualitatively and effectively influences its sports results

This study examines the extent of agreement or disagreement among and between Texas superintendents, principals and athletic directors toward fifty specifically defined role expectations for the full-time athletic administrator. By defining the athletic director's role expectations, the superintendents, principals and athletic directors may function more effectively in discharging their duties and implementing quality interscholastic athletic programs. Parents and educational leaders are very interested in athletic programs which contribute to the emotional, social, physical, and mental growth of youth. Given the increasing number of athletic programs and participants, it is important to analyze and report data related to athletic administration. The perceptions of the superintendents, principals, and athletic directors to the specifically defined role expectations for the athletic director provided data for analysis to determine the extent of role conflict and the role of the athletic director. The main findings are the following. (1) There is a minimal role conflict for the athletic director based upon the perceptions of the superintendents, principals, and athletic directors. (2) The majority of the respondents agreed or strongly agreed with forty-four of the specifically defined role expectations for the athletic director. (3) The majority of the respondents disagreed or strongly disagreed with the athletic director being responsible for establishing an athletic program that has a primary objective of producing a financial profit, being responsible for securing advertising to support the game program, directing and supervising the kindergarten through grade twelve physical education and health education programs, reporting directly to the local principal(s), and being responsible for the concession operations at athletic contests. The recommendations, based upon the data from this study, are: (1) Texas school district personnel should review and update their job description for the athletic director in accordance with the specific role functions identified through this study, and (2) the model job description developed for the director of athletics could reduce possible role conflict.

Syftet med denna systematiska litteraturöversikt var att jämföra radiell mot fokuserad stötvågsbehandling samt att undersöka effekten utav stötvågsbehandling för att reducera smärta och återfå fysisk funktion vid Akillestendinopati. Litteraturöversikten har följt checklistan PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis). Inklusionskriterier till litteraturöversikten är utformade efter PICO (population, intervention, control, outcome) och databaser som använts är PubMed, SPORTDiscus, CINAHL, Scopus och Web of Science. Data har analyserats narrativt och tillförlitligheten hos utfallen har bedömts med GRADE.Sju studier inkluderades till litteraturöversikten varav fyra studier som utfört radiell och tre studier som utfört fokuserad stötvågsbehandling som intervention. En signifikant skillnad för smärtreduktion sågs i två av studierna för båda behandlingarna. När radiell stötvågsbehandling användes hade interventionsgrupperna en högre smärtreduktion än kontrollgrupperna och när fokuserad stötvågsbehandling användes hade kontrollgrupperna en högre smärtreduktion än interventionsgrupperna. En signifikant skillnad för återställande utav den fysiska funktionen i ankeln sågs i tre studier för radiell stötvågsbehandling och två studier för fokuserad stötvågsbehandling. Där radiell stötvågsbehandling användes hade interventionsgrupperna en större ökad fysisk funktion än kontrollgrupperna och där fokuserad stötvågsbehandling användes hade kontrollgrupperna en större ökad fysisk funktion än interventionsgrupperna.Radiell stötvågsbehandling verkar kunna fungera för att reducera smärta och öka fysisk funktion vid Akillestendinopati. Tillförlitligheten för utfallen vid fokuserad stötvågsbehandling är för låg för att kunna dra någon slutsats om vilken typ av stötvågsbehandling som är mest effektiv. Ifall det varit känt vilken typ av stötvågsbehandling som ger bäst resultat hade det varit en bra vägledning för vårdpersonal som arbetar med stötvågsbehandling. / The purpose of this review was to compare radial versus focused shock wave therapy and to review shock wave therapies usage to reduce pain and increase physical function for the Achilles tendinopathy.The review has followed PRISMA’s checklist while using PubMed, SPORTDiscus, CINAHL, Scopus and Web of Science databases. Data has been analyzed narratively and the evidence of the outcomes has been assessed.A significant difference in pain reduction was seen within two studies for both interventions. Where radial shock wave therapy was administered the intervention groups had a higher pain reduction than the control group. Where focused shock wave therapy was administered the control group had a higher pain reduction than the intervention group. A significant difference in the restoration of physical function was seen within three studies for radial shock wave therapy and two studies for focused shock wave therapy. Where radial shock wave therapy was administered the intervention groups had a greater increased physical function than the control groups and where focused shock wave treatment was administered the control groups had a greater increased physical function than the intervention groups.Radial shock wave therapy seems to be effective to reduce pain and increase physical function in the Achilles tendinopathy. The evidence of the results for focused shock wave therapy is too low to draw any conclusion, or allow us to compare the two methods. Had the studies allowed for a direct comparison between the two methods, this could have led to a guide for healthcare professionals.

Popliteal artery entrapment syndrome has been reported to be a rare disease typically found in athletic and otherwise healthy young adults. It manifests as a temporary lower limb pain that occurs in connection with physical exercise. It is caused by an anatomic anomaly, usually anaberrant head of the gastrocnemius muscle that compresses the popliteal artery on the backside of the knee joint. The popliteal artery is the main vessel supplying blood to the lower part of the leg and the condition, if left untreated, can lead to serious complications such as thrombosis or aneurysm. If detected in time and surgically corrected patients can expect full recovery within weeks.The purpose of this study was to examine a group of healthy asymptomatic individuals (n=50)using ultrasound and a series of provocation to see if there was a possibility of entrapment. A secondary objective was to find which maneuvers during the ultrasound would provide the best results. They were subjected to ultrasound examinations at rest, during plantar flexion without resistance, against a light resistance and against substantial resistance.The results showed that most of the test subjects could temporarily constrict blood flow greatly although ultrasound imagery alone was not enough to confirm diagnosis. It seems that detected occlusion of the artery in conjunction with other diagnostic data such as AnkleBrachial Index and symptomatology can be useful both in confirming or ruling out PAESwithout the use of more expensive and invasive methods.
