Sendo assim, para otimizar o deslocamento nos nadadores pode-se otimizar a força propulsora. Para isso, pode-se utilizar palmares e parachute. Os palmares tem como função promover o aumento artificial da área da mão, desta maneira, aumenta-se a área frontal da mão do sujeito em contato perpendicular com o fluxo d'água, aumentando a propulsão. O parachute atua no aumento do arrasto dos nadadores, assim, estes tem que reorganizar o recrutamento neuromotor para que possam superar esse aumento da resistência externa. Assim sendo, durante o uso dos palmares existe diminuição da frequência e aumento do comprimento de braçadas enquanto com parachute ocorre o oposto, em ambas as variáveis. Contudo, pouco se sabe sobre o comportamento das variáveis coordenativas no uso destes implementos, desta forma, este estudo tem por objetivo verificar a influência de palmares e parachute na coordenação dos nados borboleta e crawl. Participaram do estudo 21 nadadores de nível estadual, estes eram especialistas em nado borboleta e crawl, com experiência no treinamento com palmares e parachute. O protocolo foi composto por 4 tiros de 25 metros: nado sem equipamentos, com palmares, com parachute e com palmares mais parachute. Todos os nadadores foram filmados (60 quadros por segundo e shutter speed de 1/1000) por um trolley que se deslocava paralelamente aos nadadores. Foram mensuradas velocidade média, frequência e comprimento de braçadas, fases de braçada, fases das pernadas, índice de coordenação específico do nado. Os principais resultados apontam que a velocidade de nado de acordo com o tipo de sobrecarga, diminuição com sobrecarga resistiva e mista enquanto aumento na propulsiva. A frequência de braçadas diminuiu com todos os implementos enquanto o comprimento aumentou apenas na condição com utilização de palmares. Nenhuma fase da braçada e da pernada foi modificada em nenhum dos nados. O índice de coordenação no nado borboleta sofreu grandes modificações, de acordo com a condição experimental enquanto para o nado crawl a sobrecarga parece diminuir os intervalos não propulsivos. Concluiu-se que o uso dos implementos deve estar programado tanto na sessão de treino quanto ao longo da temporada, visto que mais estudos são necessários para mapeamento dos efeitos da utilização longitudinal / Abstract: Swimming is a sport that has achieved high levels of demand, which is reflected on training sessions and researches. So, to optimize the displacement in swimmers can optimize the propulsive force. For this, can be used hand paddles and parachutes. The hand paddle enlarge the artificial area of the swimmers hand. The parachutes enlarge the drag on swimmers, so, they have to reorganize the neuromotor recruitment to overcome this increase on external resistance. Thus, during use of hand paddles there is decrease of stroke rate and during use of parachutes there is increase of stroke length, while the opposite occurs in both variables during use of both implements. However, on literature has few studies about coordenatives variables on overload in swimming, therefore, the aim of this study is investigate the influence of hand paddles and parachute on coordination of butterfly and front crawl swims. 21 estate level swimmers were the subjects of this study. They were specialized on butterfly swimming or front crawl swimming, all with experience in training with use of hand paddles and parachute. The tests protocol was four maximal-intensity conditions: without equipment, with hand paddles, with parachute, and with both hand paddles and parachute. All swimmers were filmed (60 frames per second, 1/1000 of shutter speed) from a moving sagittal view, with the aid of a trolley pulled by an operator at the same velocity as that of the swimmer. Swimming velocity, stroke rate, stroke length, stroke phase and leg kicking duration and index of coordination for each swim style were analyzed from videos. To according the overload, changed the speed of swimming. The stroke rate decreased with all implements. Stroke length increased only on hand paddles condition. No one stroke phase neither leg kicking were modify, for butterfly and front crawl swimming. The according for the experimental condition the index of coordination of butterfly swimming was modify while the index of coordination of front crawl swimming on overload appears to decrease the lag time of propulsive continuity. The implements use must programmed for training session and periodization. So, many researches are necessary for understanding the longitudinal effects of these implements / Mestrado / Biodinamica do Movimento e Esporte / Mestre em Educação Física

Title: Non-verbal expressions in the students' didactical outputs at the Charles University, the Faculty od Physical Education and Sport in the subject Theory and basics of swimming didactics Purpose: The aim of this diploma thesis is to consider the degree of selected aspects of the non-verbal expressions in the studens' didactical outputs at the Charles University, the Faculty of Physical Education and Sport and to evaluate non-verbal differences between males and famales and between students with more focus on swimming and those who only participated in swimming lesson obligatory. Methods: Observation and video analyzing methods were used for the reserch of the selected aspects. The analysis of the video recording results is presented in graphs. Results: The video analysis method seems to be appropriate for examining the students' didactical outputs. The frequencies of the selected non-verbal acpects of the individuals in the research are intraindividually different. When comparing the students' non-verbal expressions defferences were found in quarter of the observed cases. The differences among students with a higher focus on swimming and those who only compledes obligatory swimming lessons appeared in all cases. They were positive for the students with a higher focus on swimming, but in the...

Title: Comparative analysis of the crawl pattern and specific exercises. Purpose: The aim of the dissertation is to evaluate the coordination similarity ratio of involvement of selected muscles during the crawl swimming cycle as a target movement with imitation movement acts. Methods: The research study has the character of an intra-individual and inter- individual comparative analysis of the coordination characteristics of the movement system. This is a sequential triangulation of a quantitative-qualitative approach and an intragroup case study with an experimental way of getting data. Results: Muscle activation of selected muscles during the crawl did not show a significant difference in effect size compared to the imitation movements on the Biokinetic swimming simulator and exercising with swimming expanders.

Title: Swimming Aids in the Swimming Classes for Mentally Disabled Objectives: The aim of the thesis is to identify the effectiveness of swimming aids in the education of mentally disabled. The objective was to collect information from the lectors of swimming classes for mentally disabled people in the Czech Republic. Finally, the data obtained from the questionnaire could suggest the use of floatation aid or other swimming aid during the process of learning how to swim and move in the water. Methods: A method of a questionnaire was used to collect the information: selected swimming lectors specializing in swimming of disabled were invited to fill it out. Answers were analyzed and interpreted in the results section of the thesis, and were supported with tables. Results: Author's research has shown that the inclusion of mentally disabled in swimming classes has progressed. However, in the Czech Republic it was impossible to focus solely on mentally disabled as the swimming classes usually involve people with other disabilities as well. The use of an assistant during the swimming classes was very common. Author confirmed the preference of certain swimming aids among the lectors, and on the other side, some aids were no longer used. Finally, the use of swimming aids mainly supported the overcoming of...

Aim The aim of this study was to ascertain the effect of resisted sprint training in swimming on maximal swimming velocity and performance characteristics. The aim was also to examine how maximal swimming velocity is related to maximal swim power and maximal dry-land power. Method Eighteen competitive national level swimmers (9 male and 9 female; age: 18.3 ± 2.3 years, body mass: 72 ± 8.3 kg, height: 177.2 ± 4.6 cm, mean ± SD) were recruited to this study. Subjects were assigned to either resisted sprint training (RST) or unresisted sprint training (UST). Sprint training was performed two times per week during 6 weeks as 8x15m with a 2min send-off interval. RST performed sprint training using individualized load corresponding 10% of maximum drag load (L10), UST performed sprint training with no added resistance. A test-battery including dry-land strength assessment; maximal strength (MxS) and explosive strength (ExS), a timed 25m front-crawl swim and in-water force-velocity profiling was performed prior and following the training intervention. Maximal swim power (Pmax), maximum drag load (F0), theoretical maximum velocity (v0) and slope of force-velocity curve (SFv) was computed though force-velocity profiling. Results No significant within group differences occurred in neither RST nor UST following the 6-week intervention period in: swimming velocity, MxS, ExS, Pmax, F0, v0, and SFv. Strong correlations were found between swimming velocity and MxS (r = 0.75), ExS (r =0.82) and Pmax (r = 0.92). Conclusion Resisted sprint training in swimming using L10 did in the present study not elicit any improvements in maximal swimming velocity or examined performance characteristics. Resisted sprint training does not appear to be a superior method of improving swimming performance compared to unresisted sprint training. MxS, ExS and Pmax can be used as robust predictors of swim performance, however only Pmax was found to be casually related to swimming velocity.
