Spread of popularity of short track speed skating in the world and in Lithuania, rapid rise of mastery and increasing concurrence and competition among sportsmen encourage a study of scientifically based technologies of preparation for the short track speed skating. The paper overviews the characteristics of the development of structure in short track speed skating long-term trainings together with methods of training, physical and functional development. The aim of the paper: to find out the peculiarities of short track speed skating sportive training i.e. preparation in Lithuania. People under investigation were the members of the national short track speed skating team of Lithuania – S.K., P.G. and A.S. Sportive achievements and the analysis of training strain of the skaters were observed. Laboratory research has been done in the laboratory at the main meso-cycle of special preparation in Vilnius Pedagogical University. It was the first time that the skater S.K. has taken part in the research that has been done in Lithuania. Examination of sportsmen’s physical development and sportive readiness was accomplished in general and the special meso-cycles of preparation. The results of the research correspond to the norms that are set to the sportsmen. A programme for a year’s period of sportive preparation to Lithuanian short track speed skating team was structured. The programme consists of the following issues: selection of sportsmen and groups of age, physical strains and... [to full text]

Athletes competing in contact sports commonly wear intra-oral dental mouthguards. Data are sparse concerning the influence of a mouthguard on breathing during exercise. We compared VE and VO2 during submaximal and maximal exercise on a skating treadmill (TM) while wearing an intra-oral dental mouthguard. Female varsity hockey players (n = 12) performed two skating tests on a TM with and without a mouthguard (WIPSS Jaw-Joint Protecto(TM)). The players wore the mouthguard during hockey practices prior to collection of ventilation data on the treadmill. Also, the players completed a questionnaire that examined their perceptions of the mouthguard in terms of ventilation, comfort and performance. A 10-point rating scale was used for this evaluation. Two performance tests on the skating treadmill examined the effect of the mouthguard on submaximal and maximal aerobic exercise. The subjects skated for 4 min at 2 submaximal velocities (14 and 16 km·h-1 ) separated by 5 min of passive recovery. A VO2 max test followed the submaximal tests and commenced at 18 km·h-1 with the velocity increasing by 1 km·h-1 every minute until volitional fatigue. VE, VO2, VCO 2 and RER were analyzed using a Sensor Medics 2900 metabolic cart. Two-way (2 conditions x 3 velocities) repeated measures ANOVAs were used to examine differences in VE, VO2 and HR. Ventilation was unchanged when skating at the two submaximal velocities. VO2 max was 48.8 ml·kg-1·min-1 using the intra-oral mouthguard and was 52.4 ml·kg-1·min -1 without a mouthguard. VE max was 108.5 L·min -1 using the intra-oral mouthguard and was 114.1 L·min -1 without a mouthguard. The results showed that VE max and VO2 max were lower using the mouthguard compared to the no mouthguard condition.

The purpose of this study was to investigate the effect of selected warm-up protocols (WUP) on forward ice-skating and perception of readiness to perform (RTP). Twenty male Jr. A hockey players (age = 18.7 ± 0.9 yrs; experience = 1.6 ± 1.0 seasons) participated in the study. Participants completed five different conditions: one with no warm-up (NO) performed on the first day and four WUP sessions administered in random order. WUP included: a) complete Hockey Canada WUP (HC), b) Hockey Canada off-ice only WUP (OFF), c) Hockey Canada on-ice only WUP (ON), d) on and off-ice explosive specific WUP (ES). Testing sessions consisted of the WUP followed by 15 minutes of rest after each on and/or off-ice portion. Skating performance (SP) was measured with infra-red timing gates (Brower Timing Systems, Utah, USA) at 4, 8, 12, 16 and 20 m. Three maximal trials with three minutes rest between trials were performed and averaged for statistical comparison. Significant SP differences occurred between ES vs. NO and OFF at all distances. Significant SP differences occurred between HC and ON vs. NO and OFF at 4 m and between HC and NO from 2 to 16 m. RTP was determined through a visual analogue scale question posed immediately pre and post- WUP and pre-SP. RTP increased significantly with each WUP while pre-WUP and pre- SP RTP scores were not significantly different across WUP. No correlation between RTP and SP was found.

Figure skating is a competitive sport that requires intensive training which can be taught in a variety of settings. There are various methods to teaching figure skaters new skills such as positive and corrective feedback, modeling and coaching procedures, and physical guidance. These different approaches may lead to a lack of consistency among coaches. Over the years, these established coaching strategies have not changed substantially as training methods are passed down from coach to student. Also, research in the area of what constitutes effective coaching methods is lacking. Skaters may progress more quickly in skill development if coaches are implementing empirically based successful coaching methods. These teaching approaches may also be enhanced by incorporating the latest technology available. This study evaluated the effectiveness of a video feedback coaching procedure using the Dartfish application. A multiple baseline design was utilized to document the impact of this video feedback coaching procedure on the demonstration of six established figure skating moves, three moves for one skater and three different moves for two other skaters. Results showed utilizing video feedback improved figure skater's performance levels on the targeted moves to an acquisition of 80% accuracy or higher.

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.

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.

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...
