Efeitos de dois tipos de sessão de treino em parâmetros fisiológicos e neuromusculares de patinadores

Antunes, Amanda Haberland January 2012 (has links)
A patinação artística se desenvolveu ao longo dos anos, até tornar-se o esporte de competição visto atualmente. Contudo, existe pouca informação na literatura a respeito da intensidade das sessões de treino desta modalidade e se existiria uma maneira de expor o atleta a um menor número de impactos dos saltos durante o treino, mas atingir os mesmos benefícios. Sendo assim, o objetivo do presente estudo foi comparar os efeitos de dois tipos de sessão de treino de patinação sobre parâmetros fisiológicos e neuromusculares de atletas da patinação artística sobre rodas. Nove atletas (17,7 ± 2,96 anos) realizaram dois diferentes tipos de sessão de treino, de forma randomizada: uma sessão convencional (conv) (na qual o número de saltos e os intervalos realizados foram determinados pelo técnico das atletas, conforme o treinamento normalmente realizado pelas mesmas, resultando em uma média de 139 ± 31,2 saltos) e uma sessão sistematizada (sist) (na qual foram realizados 96 saltos, com intervalo de 6 s entre cada salto, 2 a 3 min entre cada repetição (conjunto de oito saltos) e 5 min a cada quatro repetições). As atletas foram avaliadas antes, imediatamente após, 5 min, 10 min, 15 min, 30 min, 24h, 48h e 72h após a realização das sessões, em parâmetros relacionados à atividade muscular, taxa de produção de força, altura e potência dos saltos squat jump (SJ), counter movement jump (CMJ) e drop jump (DJ) e concentração sanguínea de creatina quinase e de lactato. Foi utilizado o Teste T para amostras pareadas para a comparação entre as sessões nos diferentes momentos, sendo adotado um α=0,05 como significância (SPSS v. 17.0). Foram observadas algumas diferenças significativas entre as sessões, dentre elas, na concentração sanguínea de lactato no momento 15 min após (conv: 1,47 ± 0,45 mmol; sist: 1,03 ± 0,25 mmol; p=0,044) e na altura dos saltos SJ, no momento 72h após (conv: 0,20 ± 0,06 m; sist: 0,18 ± 0,06 m; p=0,012), e CMJ, também no momento 72h após (conv: 0,21 ± 0,06 m; sist: 0,20 ± 0,06 m; p=0,008). Porém, de maneira geral, foram observadas poucas diferenças significativas entre as sessões de treino avaliadas no presente estudo, o que indica que ambas representaram uma intensidade semelhante de treino. No caso da sessão sistematizada, os achados confirmam a hipótese de que uma sessão de treino com número de saltos e tempo de intervalo definidos seria uma alternativa interessante de expor menos o atleta a uma grande quantidade de impacto e, ainda assim, atingir os mesmos resultados de uma sessão convencional. / Artistic roller skating has been developed over the years to become the competitive sport currently seen. However, little information exists in the literature regarding the intensity of the practices of this sport and if there could be a way to expose the athlete to a lower number of impacts of the jumps during training, but at the same time to achieve the same benefits. Therefore, the objective of this study was to compare the effects of two types of skating training session on physiological and neuromuscular parameters of roller figure skaters. Nine female athletes (17.7 ± 2.96 years) realized two different types of skating training session: a conventional session (conv) (in which the number of jumps and the intervals were determined by the athlete’s coach, according to their normal training scheme, resulting in a mean of 139 ± 31,2 jumps) and a systematized session (syst) (in which 96 jumps were performed with intervals of 6 s between each jump, 2 to 3 min between each repetition (set of eight jumps) and 5 min every four repetitions). Evaluations were done before, immediately after, 5 min, 10 min, 15 min, 30 min, 24h, 48h and 72h after the sessions in parameters related to muscular activity, rate of force development, height and power of squat jump (SJ), counter movement jump (CMJ) and drop jump (DJ) and blood concentration of creatine kinase and lactate. Paired T Test was utilized for the comparison between sessions at the different time points, with an α=0,05 as significance (SPSS v. 17.0). Some significative differences between sessions were observed, as in the blood concentration of lactate at the moment 15 min after (conv: 1,47 ± 0,45 mmol; syst: 1,03 ± 0,25 mmol; p=0,044) and in the heights of SJ at the moment 72h after (conv: 0,20 ± 0,06 m; syst: 0,18 ± 0,06 m; p=0,012), and CMJ, also at the moment 72h after (conv: 0,21 ± 0,06 m; syst: 0,20 ± 0,06 m; p=0,008). However, there were overall few significant differences between the sessions evaluated in the present study, what indicates that both represent a similar training intensity. For the systematized session, the findings support the hypothesis that a training session with defined number of jumps and rest intervals could be an alternative to expose less the athlete to a large amount of impact and yet get the same results of a conventional session.

Kompenzační cvičení jako doplněk tréninkového plánu dětí mladšího školního věku v krasobruslení / Compensation exercise like a supplement of young school age children in figure skating

Nowická, Eva January 2018 (has links)
Title: Compensatory exercise as a complement to the training schedule for children of younger school age in figure skating Objectives: The main objective of this work is to identify the most frequently occurring muscular dysbalance in the studied group of younger school-age figure skaters. Therefore, in order to find out the fundamental deficiencies, we used simple tests and based on the deficiencies, we created a buffer of compensatory exercises. We will verify the results using the same tests as at the beginning of the initial measurement after the three-month preparatory period. Methods: In my work I used a functional muscular test to assess the flexibility and examination of a physiotherapist with the help of the MFK system. We do not only measure the muscular strength of the main muscle in individual tests, but we also investigate and analyze the performance of the whole movement. Testing was attended by five figure skaters in the younger school age. Results: Initial testing took place at the start of the preparatory period. A 3-month compensation program was then applied and after the test, the probands were again tested to determine the effect. The results of this work are described in the tables. The result of this work is that the most problematic parts were the abdominal, back muscles and...

Nowická, Eva January 2017 (has links)
Title: Compensatory exercise as a complement to the training schedule for children of younger school age in figure skating Objectives: The main aim of this work is to highlight muscle dysbalance and their subsequent weakening and hypermobility in younger school age children in figure skating. Based on these weaknesses, create a stack of release, stretching and exercise exercises that can be used under any circumstances. Methods: In my work, I used a Janda muscle test, an analytical method that was focused on determining the strength of each muscle group. In individual tests, we are not only measuring the muscular strength of the main muscle, but we also investigate and analyze the performance of the whole movement. I was based on qualitative and quantitative values. Results: The measured data were compared and evaluated according to the literature. The impact of one-sided load in the long-term sports practice of figure skating was confirmed. It has also been shown that these exercises can be used for this particular set of probands to compensate for unilateral loading and adjust the training so that compensatory exercises are part of the training. Furthermore, I managed to design a program that would reduce these weaknesses for this selected group of probands. Keywords: Figure skating, training,...

Štefl, Karel January 2020 (has links)
Title: Experiences of trainers with conditioning preparation of figure skaters off ice Objectives: The thesis will focus mainly on specialized and general training of children of a given age category (JUNIORS 15-19 YEARS) and on motor tests suitable for testing the skills most needed for figure skating, but outside the ice. Although this issue is described, although there are not so many literatures in the Czech Republic. The trainers will be interviewed, which will then be processed into a comprehensive and clear form. Methods: The questioned group consisted of 8 coaches I. and II. coaching class of figure skating. Using a guided interview, we asked 10 questions in total. Questions were focused on fitness training of figure skaters off ice. Results: Evaluation of the results enabled us to find out some interesting facts. These include the use of a spinning bike, like form of imitation of HF after of with injuries. Another valuable piece of information was the use of a rotary auxiliary device to improve coordination and reduce knee load. we also learned that running training should be eliminated for the development of endurance due to the heavy load on the knees. Training in fresh air in all weather was also a positive finding for our needs. Overcoming the aversion to training in bad weather can...

The effects of different figure skating boots on the kinetic and kinematic properties of the landing impact and changes as the boot ages.

Spiegl, Ondrej January 2017 (has links)
Aim: The intention of this study was to examine whether different brands and models of skating boots differently affect the kinetic and kinematic properties of a landing impact from a jump. The differences were tested between new figure skating boots Graf Edmonton, new Edea Concerto and old used Graf Edmonton. Method: Subjects simulated a figure skating jump landing by landing from a counter movement jump off boxes of two different heights onto artificial ice in the Biomechanics and Motor Control (BMC) laboratory. During these jumps the subjects wore figure skating boots of different age and types. Landing impacts were examined by Qualisys motion capture system, Kistler force plate and Pedar-X in-shoe force and pressure measuring system. Each subject acted as his own control for comparison of kinetic and kinematic variables between the skates. Statistical comparison was carried out in SPSS. Results: The research results indicate that the kinetic and kinematic properties of a landing impact significantly (P≤0.05) differed depending on the tested skates. Significant differences were found between new Graf Edmonton and old used Graf Edmonton, between new Graf Edmonton and new Edea Concerto as well as between old used Graf Edmonton and new Edea Concerto. Conclusions: The first research hypothesis was accepted, indicating that reduced vertical ground reaction force (VGRF) acted in new Edea Concerto compared to new and old, used Graf Edmonton boots. The second research hypothesis was rejected since the VGRF acting during the landing impact in old, used Graf Edmonton was greater compared to new Edea Concerto and there was no significant difference compared to new Graf Edmonton boots. The differences between the figure skating boots found in this research are suggested to be caused by different construction designs and materials used in the skates. / <p>Kursen Projektarbete.</p>
