No entanto, poucas informações científicas têm sido encontradas na literatura, sobretudo, em relação a avaliação fisiológica e treinamento. Objetivo: padronizar testes específicos em remada atada e livre para avaliação da aptidão aeróbia de canoístas slalom de elite e verificar a correlação dos índices de aptidão aeróbia fornecidos pelos testes com o desempenho em prova simulada. Métodos: a amostra foi composta por 12 atletas pertencentes a Seleção Brasileira Permanente de Canoagem Slalom com idade média 18 ± 2 anos. Os testes de canoagem atada foram realizados com o auxílio de um aparato denominado Sistema de Medição de Força Atado (SIMFA), composto por célula de carga e módulo amplificador de sinais. Todas as avaliações foram realizadas em piscina de 25m e sob caiaque modelo K1. A máxima fase estável de lactato (MFEL) atada foi determinada a partir de três intensidades que variaram de 35,5N à 70,3N. Para a obtenção da força crítica (FC) foram utilizadas quatro cargas preditivas e ajustes matemáticos hiperbólico (FChiper) e linear (FClin). As avaliações em remada livre (velocidade crítica (VC) e MFEL) foram realizadas em lagoa. A VC foi obtida pelo modelo "distância vc. tempo" utilizando desempenhos máximos nas distâncias de 300, 450 e 600 metros. Para determinar a iMFEL os atletas foram submetidos a três testes contínuos com duração de 30 min, separados por intervalo de 24 horas entre eles, realizados em sistema de vai e vem na distância de 50 metros. Como indicador de desempenho adotou-se o tempo em prova simulada de canoagem slalom (TP), executada em canal artificial. Em adição o lactato sanguíneo (LACsang) pós prova foi mensurado. Resultados: os principais resultados das avaliações atadas, indicam não haver diferença entre a iMFEL e FChiper e entre FChiper e FClin, no entanto, a FClin foi significantemente maior que iMFEL. A FChiper foi altamente correlacionada com iMFEL (r= 0,78, p=0,002), bem como iMFEL foi correlacionada com desempenho (r = -0,67, p=0,016). Em relação as avaliações livres os resultados revelaram não haver diferença significativa entre a intensidade de VC (7,77 ± 0,28 Km/h) e iMFEL (7,50 ± 0,32), além disso, correlação significativa foi encontrada entre a intensidade de VC e desempenho em prova simulada (r= 0,84, p=0,03). Conclusões: em relação as avaliações atadas, foi possível padronizar testes atados para avaliação aeróbia de canoístas slalom, utilizando as metodologias de MFEL e FC, e também a possibilidade de utilizar o parâmetro aeróbio obtido pelo modelo de FC como uma avaliação não invasiva para estimar a MFEL. Já em relação as avaliações livres a VC obtida pelo modelo distância-tempo é válida para estimar a iMFEL em canoístas slalom de elite, além de se correlaciona com o desempenho em prova simulada. / Abstract: Introduction: canoe slalom is an Olympic sport since 1992 and that grows every year worldwide. However, limited scientific information has been found in the literature, especially in relation to training and evaluation physiological. Purpose: Standardize tethered specific tests and free tests for assessment of aerobic fitness elite slalom kayakers and additionally verify the correlation between indexex of aerobic fitness provided by tests with performance in simulated slalom race. Methods: the sample was composed of 12 athletes from the Canoe Slalom Brazilian Team with a mean age 18 ± 2 years. The tethered specific testst was performed using a denominated Tethered Canoe System (TCS) constructed specifically for this purpose composed of a load cell and signal amplifier module. All assessments were conducted in a 25-meter outdoor swimming pool using K1 kayak model. The tethered maximal lactate steady state (MLSS) was determined from three intensities ranging from 35,5N the 70,3N. Four predictive loads were used to obtain the critical force (CF) using two mathematical adjustments, hyperbolic (CFhiper) and linear (CFlin). Free specific tests assessments (critical velocity (CV) and MLSS) were performed in lake. The CV has been obtained by "distance-time" model using maximum performance at distances of 300, 450 and 600 meters. To determine the iMLSS athletes underwent three continuous lasting 30 min, separated by 24-hour interval between them, performed using a kayak "shuttle" exercise, with a 50-m course. The simulated race was conducted on a white water course and as performance indicator the total race time (Trace) was adopted. In addition, the blood lactate (LACsang) post race was measured. Results: the main results of tethered evaluation, indicate that the CFlin and CFhiper intensities did not differ, as well as CFhiper and iMLSS. However, CFlin was significantly higher than iMLSS. The iMLSS and CFhiper intensities were significantly correlated (r= 0.82, p=0.002) well as iMFEL was correlated with performance (r = -0.67, p = 0.016). Regarding the free evaluations, the results showed no significant difference between the intensity of CV (7.77 ± 0.28 Km / h) and iMLSS (7.50 ± 0.32) Moreover, a significant correlation was found between intensity CV and simulated race performance (r = 0.84, p = 0.03). Conclusions: regarding the tethered specific tests , was possible to standardize tests for aerobic evaluation in slalom kayakers, using the MLSS and CF methodologies and also the possibility to use the aerobic parameter obtained by the FC model as a noninvasive evaluation to estimate MLSS. In relation the free specific tests, the CV obtained by the distance-time model is valid for estimating the iMLSS in elite slalom kayakers and is correlated with performance in simulated race / Doutorado / Biodinamica do Movimento e Esporte / Doutor em Educação Física

To date, most of the research on group cohesion has focused on team sports, with little known about how this body of knowledge relates to individual sports. The case of the male French whitewater slalom canoe and kayak team was chosen because of the success of the team at World Championships and Olympic Games. The purpose of the present case study was to investigate how the coaches and athletes of this highly successful team worked together in training and competition within a highly competitive environment. Data were collected through in-depth interviews with six athletes and four coaches. Three themes, each containing numerous sub-themes, emerged from the analysis: (a) the nature of collaboration within the team environment, (b) coach leadership, and (c) the fragility of collaboration. The results of the present study have advanced our understanding of what collaboration within an individual sport team may look like. For a period of time, the leadership skills of the coaches, as well as their technical coaching expertise, and the willingness of the talented and driven athletes to work together, contributed significantly to a collaborative environment for this team. Then a change in the Olympic entry rules, the departure of an influential coach, and the inevitable change in the ages and experiences of the athletes themselves all combined to erode the foundation of that productive and collaborative environment.

Title: Nutrition monitoring in top Czech Republic women white water slalom athletes in the race period of the season. Aim of the study: Comparison of actual quantitative and qualitative composition of the diet in the Czech water slalom paddlers (women) in the racing period to daily recommended standards for the population group of athletes with a corresponding energy output. Using the results, create both general and individual recommendations and assess the need for the use of supplements in the diet of water slalom athletes. Methods: The thesis is a case study and it is a kind of qualitative research. For our study we chose two main methods. Prospective study method and the method of interview. To determine the total daily energy intake and diet quality inventorial analysis of the four- day dietary record of the respondents was used. For comparison with the standards, the data were subsequently processed by standardized software applications of database functions MS Excel (Vilikus a kol., 2002) and accompanied by a critical commentary. To survey the data concerning use of food supplements has been used a method in which athletes respond to questions asked. The data were assessed in writing and graphically. Results: Our study shows and critically comment on the differences between recommended and...

Thesis title: A description of significant differences in technical preparation of water slalom and canoe sprint in K1 category. Thesis objective: The objective of the thesis is to determine the main features typical of technical preparation of kayakers in Czech canoeing clubs and to describe possible differences in the preparation of sprint kayakers and water slalom kayakers. Methods of data processing: The work is based on mixed research. The racers and coaches were presented with a questionnaire concerning technical preparation. Collected output was analyzed using the methods of quantitative research and of analytical induction. Results: Several significant differences were detected between the technical preparation of sprint kayakers and water slalom racers. To develop basic kayaking strokes, water slalom racers in mostly younger age categories use other water sports, especially wild water, more frequently. In preparatory exercises sprint racers limit themselves to stroke sequencing. Water slalom racers use a wider range of preparatory exercises to develop basic kayaking stroke. In order to gain feedback, water slalom racers use videorecording analysis several times a month and that not only during technical preparation period. In sprint canoeing the videorecording analysis is used...

Title: Performance aspects in white water slalom Aim The study is a summary of articles published between the years 2006 - 2011. The aim is to present the researched issue of top - level sport in the example of white water slalom. Articles are arranged in accordance to the factors of sport performance. The first thematically include articles concerned with conditioning factors of performance, then continue articles analyzing somatic factors and at the end there are listed papers on psychological preparation and psychological factors. Methods These articles were mostly case studies which have been conducted on a sample of national team athletes or top athletes in the Czech Republic. The exception is the articles 5.3 and 5.4, which are descriptive studies on a large sample of top world class athletes. The studies used a survey and testing. Results The individual articles addressed the importance of performance indicators in white water slalom, applied to the selected factors. Results of studies are always subjected to deliberately selected files of athletes, top-level competitors in the Czech Republic and abroad. The results, therefore, cannot be generalized and applied to a population of white water slalom racers, but can show some patterns that could be accepted in practice.
