Nos últimos anos as bicicletas de competição passaram por grande evolução tecnológica, sendo constituídas de materiais leves e resistentes, importantes para o aumento do rendimento desportivo, porém apenas a facilidade de acesso a esses recursos, por si só não garante o sucesso competitivo. Existem questões fundamentais relacionadas a eficiência de um sistema de preparação do desportista que estão relacionadas ao controle da carga de treinamento, tomando necessário estabelecer parâmetros a partir dos quais os estímulos possam ser efetivos. O presente estudo teve como objetivo apresentar uma proposta do controle de exercícios especiais para dois ciclistas velocistas de alto nível. Dois ciclistas masculinos (idades 29 e 25 anos) de nível internacional (Panamericano) foram avaliados em três momentos distintos de um macrociclo, início e fim do período de preparação e fim do período competitivo, totalizando 11 semanas de duração. Considerou-se a força média (N) aplicada e a cadência média (rpm) de pedalada na distância de 200m, percorrida em formato competitivo para orientar as zonas de intensidade. As zonas foram classificadas em percentuais da cadência do exercício competitivo (COMP): 110%, velocidade supra máxima (SM); 90%, velocidade quase máxima (VM); 85%, resistência de velocidade (R V); de 45 a 50%, resistência de força especial III (RFE III); 50 e 60% resistência de força especial II (RFE II) e 60 e 70%, resistência de força especial I (RFE I). No caso dos esforços RFE I, RFE II e RFE III, foram realizados respectivamente em rampas com inclinações de 2,04; 4,44 e 7,54%, para assegurar que com a diminuição da cadência a força aplicada fosse superoior a força do exercício competitivo; nas demais situações os esforços foram realizados em um velódromo com dimensões oficiais. Os ciclistas usaram suas próprias bicicletas de competição equipadas com um pedivela instrumentado para medir a força aplicada e a cadência. O teste de Kruskal-Wallis revelou não haver diferenças na força aplicada em cada zona proposta nos diferentes momentos de avaliação dos ciclistas (p < 0,05). Os dados revelam que a força média aplicada está diretamente relacionada à massa corporal, frequência de pedalada e percentual de inclinação das rampas. Portanto, o controle do volume e da intensidade dos exercícios de preparação física especial podem ser calculados conforme as zonas propostas, visando entender a relação entre os diferentes componentes de treinamento nos diferentes momentos da preparação. Espera-se que a partir da relação entre a dinâmica da carga de treinamento e da dinâmica dos diferentes marcadores funcionais, possa-se inferir sobre a eficácia ou as limitações do processo de treinamento. / Abstract: The cyc1ing is an Olympic sport composed by events with different motor capacities, demanding a particular and deepened study of each one. In the last years the race bicycles had passed for great technological evolution, making of the light and resistant materials, important for the increase of the sporting performance, however only the easiness of access to these resources, by itself does not guarantee the competitive success. Basic questions related to the efficiency of the preparation system of the athletes exist that are related to the control of the training load, becoming necessary to establish parameters from which the stimulus can be effective. The present study has the objective to present a proposal of control of the specific exercises for two high class cyc1ists. Two male cyc1ists (ages 29 and 25 years) of intemational level (Pan-American) had been evaluated at three distinct moments of a macrocyc1e, beginning and end of the preparation period and end of the competitive period, totalizing 11 weeks of the duration. Considered the average of strength (N) applied and the average of cadence (rpm) in the distance of 200m, covered in competitive format to guide the intensity zones. The zones had c1assified in percentages of the competitive exercise cadence (COMP): 110%, supra maximum speed (SM); 90%, almost maximum speed (VM); 85%, resistance of speed (RV); of 45 and 50%, resistance of special force III (RFE III); 50 and 60% resistance of special force II (RFE II) and 60 and 70%, resistance of special force I (RFE I). In the case of efforts RFE I, RFE II and RFE III, they had made in slopes with of 2,04; 4,44 and 7.54%, to assure that with the reduction of the cadence the strength applied was superior to the strength of competitive exercise; in the others situations the efforts had realized in a official track. The cyc1ists had used their own race bikes equipped with a instrumented crank to measure the strength and cadence. The Kruskal-Wallis show no differences in the strength applied in each zone proposal at the different moments of trials (p < 0,05). The results demonstrate that the average of strength applied was directly related to body mass, cadence and slopes. Therefore, the control of volume and intensity of the specific exercises could be calculate in accordance of the proposals zones, for the agreement of the relation between the different components of training in the different moments of the preparation. One expects that from the relation between the dynamics of training load and the dynamics of the different functional markers, can be inferred on the effectiveness or limitations of the training process. / Mestrado / Ciencia do Desporto / Mestre em Educação Física

Tělesná příprava k vojenské části talentových přijímacích zkoušek na VO FTVS UK / Physical preparation for military part of talent entrance exams at Military Department of Faculty of Physical Education and Sport

Pros, Jakub January 2015 (has links)
TITLE OF THE WORK Physical preparation for the military part of the talent exam at Military Department of the Faculty of Physical Education and Sport in Prague. DEFINITION OF THE PROBLEM It is necessary to pass the special physical exam to be admitted for studying at Military Department. The content of this exam is significantly different from other physical activities and the preparation for it may cause several problems to the candidates. MAIN GOALS The main goal of this diploma thesis is to create a package of the exercises used for improving technical and fitness part of the performance primarily in the military part of physical exam. PLAN OF PROCESSING After extensive research of the available documents the package of the exercises will be created. RESULTS Based on studying of necessary literature and using the theoretical methods the package of the exercises has been successfully created. KEYWORDS Army physical fitness, Rope ladder climbing, Load carrying, Special physical preparation, Talent test, Czech Armed Forces.
