O objetivo do presente estudo foi analisar as respostas cinemáticas e neuromusculares de diferentes saltos da patinação artística sobre rodas, com e sem patins, as respostas cinéticas dos mesmos saltos sem patins, e as respostas cinéticas e cinemáticas do countermovement jump (CMJ), drop jump (DJ) e squat jump (SJ), em patinadores de elite. Foram avaliados quatro patinadores de elite do Rio Grande do Sul, sendo estes uma mulher e um homem da categoria Junior e uma mulher e um homem da categoria Sênior. Os sujeitos participaram de três sessões: a primeira foi destinada à coleta das medidas antropométricas e à realização da contração isométrica voluntária máxima para normalização da eletromiografia, a segunda foi destinada à coleta das variáveis cinéticas, cinemáticas e neuromusculares sem patins, no laboratório, e a terceira foi destinada à coleta das variáveis neuromusculares e cinemáticas durante os saltos realizados com patins, no ginásio. Foram avaliados quatro saltos da patinação artística: Axel simples, Axel duplo, Mapes duplo e Mapes triplo. Os sujeitos executaram três saltos de cada tipo e foi selecionado aquele que estava melhor localizado dentro da zona de filmagem e que apresentou a melhor qualidade de execução. De acordo com os resultados, os patinadores homens foram mais potentes do que as mulheres durante os saltos verticais CMJ, DJ e SJ. Nos saltos da patinação os quatro atletas apresentaram maior impulso, potência máxima, altura e velocidade rotacional durante os saltos com mais rotações do que durante os saltos com menos rotações, enquanto a velocidade horizontal no take-off foi menor nos saltos com mais rotações. Na comparação entre os saltos Axel e Mapes, os patinadores demonstraram maior duração da propulsão no salto Axel do que no Mapes. Quanto à análise eletromiográfica, os músculos gastrocnêmio lateral, reto femoral, vasto lateral, bíceps femoral e glúteo máximo, apresentaram maior ativação durante os saltos com mais rotações, principalmente nas fases de propulsão e voo. Sugere-se que os resultados obtidos no presente estudo sejam considerados no planejamento de um treinamento específico, já que podem ser importantes para o desenvolvimento dos patinadores de elite, provavelmente sendo úteis também para os patinadores de outros níveis que almejam alcançar o nível internacional e obter sucesso em competições. / The aim of the present study was to analyze the kinematic and neuromuscular responses of different roller figure skating jumps, with and without skates, the kinetic responses of the same jumps without skates and the kinetic and kinematic responses of the countermovement jump (CMJ), drop jump (DJ) and squat jump (SJ), in elite skaters. Four elite skaters from Rio Grande do Sul were evaluated, including one Junior female, one Junior male, one Senior female and one Senior male. Each one took part in three experimental sessions: the first one was to collect the anthropometric data and to perform the maximum voluntary isometric contraction for electromyography normalization, the second one was to collect the kinetic, kinematic and neuromuscular variables, without skates, at the laboratory, and the third one was to collect the neuromuscular and kinematic variables during the jumps executed with skates, at the rink. Four roller figure skating jumps were evaluated: single Axel, double Axel, double Mapes and triple Mapes. Subjects executed three jumps of each type and one was selected for analysis based on the best recording area and on the overall quality of the jump. According to the results, male skaters were more powerful than female skaters during the vertical jumps CMJ, DJ and SJ. During the roller figure skating jumps, the four skaters demonstrated higher impulse, maximal power, height and rotational velocity during jumps with more rotations than during jumps with less rotation, while the horizontal velocity at take-off was lower in the jumps with more rotations. Comparing the Axel and Mapes jumps, the skaters demonstrated more duration at the propulsion phase in the Axel jump than in the Mapes. In regard to the electromyographic response, the lateral gastrocnemius, rectus femoris, vastus lateralis, biceps femoris and gluteus maximus, showed more activation in the jumps with more rotations and mainly in the propulsion and flight phases. It is suggested that the results obtained in this study are considered in planning a specific training, since they may be important for the development of elite skaters, probably being also useful for skaters of other levels that aim to achieve the international level and succeed in competitions.

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.

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,...

Bakgrund: Sportfysioterapeuter hjälper atleter att förbättra sport-specifika förmågor. Inom ishockey är slagskottet den skotteknik som producerar den snabbaste puckhastigheten. Handgreppsstyrka har visat sig vara viktig för en hockeyspelares sport-specifika förmågor och klubbrörelser. Skridskohastighet är en viktig variabel sett till hockeyspelares övergripande prestationsnivå. Syfte: Att undersöka den genomsnittliga maximala skotthastigheten, den genomsnittliga maximala handgreppsstyrkan och den genomsnittliga maximala skridskohastigheten hos en grupp manliga svenska elithockeyspelare och undersöka sambandet mellan den maximala skotthastigheten och den maximala handgreppsstyrkan samt skridskohastigheten. Metod: Ett lag på tjugotre manliga elithockeyspelare tillfrågades varav tjugo deltog i studien. Endast utespelare tillfrågades. Tvärsnittstudie med kvantitativ ansats bestående av enstaka mätningar på en grupp. Skotthastighet, handgreppsstyrka och skridskohastighet mättes en gång per testperson vid tre separata tillfällen. Resultat: Sjutton hockeyspelare slutförde studien. Den genomsnittliga maximala skotthastigheten var 128,167 km/h. Den genomsnittliga maximala handgreppsstyrkan var 60,2 kg. Den genomsnittliga skridskohastigheten var 1,405s mätt på en sträcka av 15 meter. Sambandet mellan skotthastighet och handgreppsstyrka var svagt negativt och ej statistiskt signifikant (r=-0,042; p=0,876). Sambandet mellan skotthastighet och skridskohastighet var svagt negativt och ej statistiskt signifikant (r=-0177; p=0,508).     Konklusion: De genomsnittliga maximala värdena på skotthastighet, handgreppsstyrka och skridskohastighet är jämförbara med andra studiers värden. Sambandet mellan skotthastighet och handgreppstyrka samt skridskohastighet var svagt vilket pekar på att dessa faktorer inte är en indikator på skotthastigheten vid ett slagskott. Fler studier behövs för att stödja studiens resultat. / Background: Sportsfysiotherapists help athletes improve their sport-specific abilities. In ice-hockey, the slap shot is the shot-technique that produces the greatest puck velocity. Hand grip strength have shown to be important to hockey players sport-specific abilities and stick movements. Skating speed is an important variable for the hockey players overall performance.    Aim: To investigate the mean hand grip strength, skating speed and shooting speed on a group swedish male elite ice-hockey players and investigate the correlation between these factors.     Methods: A team of twentythree male elite hockey players were asked to participate in the study. Twenty players participated. A cross-sectional study with a quantitative approach consisting of single measures on one group. Puck velocity, handgrip strength and skating speed were measured one time per player on three separate sessions.    Results: Seventeen hockey players completed the studie. The mean puck velocity was 128,167 km/h. The mean hand grip strength were 60,2 kg. The mean shooting speed were 1,405s measured on a distance of 15 meters. The correlation between puck velocity and hand grip strength were not statistically significant weak negative (r=-0,042; p=0,876). The correlation between mean puck velocity and shooting speed were not statistically significant weak negative(r=-0,177; p=0,508).    Conclusion: The mean maximal values of puck velocity, hand grip strength and shooting speed are comparable with similar values from other studies. The correlation between puck velocity and hand grip strength and shooting speed were weak which indicate that these factors do not affect the puck velocity from a slap shot. Further studies are needed to strengthen this study's result.

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...

Due to global warming our frozen lakes are becoming thinner, unpredictable and dangerous. We have already started noticing the effects of this. In recent years we have seen a steady increase in fatal ice accidents. An often-overlooked aspect within safety is our attitude towards protective gear. Through design and branding, this project explores a variety of solutions in response to the factual increase of ice- related drowning accidents in Sweden. VAK is a hypothetical brand for those who are prepared and ready to adapt to a changing environment, shaped and inspired by the raw and fickle nature of ice. Within VAK’s products several different safety aspects are touched upon, such as increased flotation, better grip and impact protection.

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>
