An analysis of the skills and tactics of wheelchair rugby

Adams, Warren Grant 03 1900 (has links)
Thesis (MScSportSc)--Stellenbosch University, 2007. / ENGLISH ABSTRACT: The purpose of this study was to determine what skills and tactics distinguish local level competition from top level competition in wheelchair rugby, through the use of games analysis. Eighteen games were filmed and analysed at three different levels of competition (local club level, regional level and international level). A five-level category set was developed to generate statistics related to successful and unsuccessful performance .. Results revealed that games play at local club and regional level in South Africa were dominated by turnovers and poor ball handling skills. Wheelchair mobility also was a factor in unsuccessful play. Basic tactical play, especially on defense, was also a major cause for concern at these levels. The difference between the South African national team and three other top international teams was not the distribution of reasons for success, but rather the frequency of success rate. South Africa was successful only 45% of the time in their performance of skills while international teams were successful 77% of the time. lt was evident in this study that the standard of play in the local club and regional level in South Africa reflects on their international performance. Ball possession is frequently lost to poor passing and poor wheelchair mobility. Turnovers are more often the result of poor passing by the opponents, rather than good defense. Successful goal inbounds and side inbounds plays are too often the result of poor defense rather than good offensive play. This study demonstrates that games analysis can be a helpful tool in determining the reasons for success and lack of success during wheelchair rugby. / AFRIKAANSE OPSOMMING: Die doel van die studie was om deur middel van die ontleding van rolstoelrugbywedstryde te bepaal watter taktieke en vaardighede in klub- en topvlakkompetisie onderskei kan word. Agtien wedstryde is op drie verskillende kompetisievlakke (klub-, streek- en internasionale vlak) verfilm en ontleed. 'n Vyfvlak kategoriestelsel is ontwerp om die suksesvlak, al dan nie, statisties in al drie kompetisievlakke aan te dui. Die resultate dui dat wedstryde op klub- en streeksvlak deur swak balhantering en verlies van balbesit (turnovers) gekenmerk word. Onvoldoende vaardigheid in rolstoelmobiliteit en tekorkominge in die taktiek van basies verdedigende spel was ook bydraende faktore. Die verskil tussen die Suid-Afrikaanse rolstoelrugbyspan en drie ander top internasionale spanne, was nie soseer verskillende oorsake vir onsuksesvolle spel nie, maar eerder die mate (hoeveelheid) sukses wat behaal is deur vaardige en taktiese spel. Die Suid-Afrikaans span was slegs 45% suksesvol in hul vaardighedsuitvoering, terwyl die internasionale spanne 'n 77% suksessyfer behaal het. Die studie dui verder aan dat die spelstandaarde wat op klub- en streeksvlak gehandhaaf word, neerslag vind in die Suid-Afrikaanse nasionale span. Hier word balbesit dikwels verloor as gevolg van swak aangee en swak rolstoelbeweeglikheid. Die verkryging van balbesit (turnovers) is meer dikwels as gevolg van swakbalhantering (aangee) deur die opponenete as goeie verdediging deur die Suid-Afrikaanse span. Suksesvolle afgooie na die aanteken van 'n doel, asook suksesvolle kant-ingooie, is eerder die resultaat van swak verdediging deur die opponente as goeie aanvallende spel. Die studie bewys dat die verfilming en ontleding van wedstryde, 'n waardevolle hulpmiddel kan wees vir bepaling van redes vir sukses, aldan nie, in rolstoelrugby.

Na primeira parte, sete tetraplégicos foram submetidos à espirometria antes e depois de treinamento de rúgbi em cadeira de rodas. Todos indivíduos apresentaram redução da função pulmonar em comparação com os valores previstos. Houve um aumento significativo na capacidade vital forçada (p= 0,01), volume expiratório forçado do primeiro segundo(p =0,02) e ventilação voluntária máxima(p= 0,03) , após um ano de treinamento.A análise de regressão entre tempo de treinamento total e as variáveis espirométricas demonstraram que os jogadores com maior tempo de treinamento tiveram maiores valores de função pulmonar (r² =0,93e 0,58, p =0,0004 e 0,004). Na segunda parte, foi estudada a análise cinemática da mobilidade toracoabdominal de tetraplégicos praticantes de rúgbi em cadeira de rodas e as diferenças de mobilidade nos compartimentos toracoabdominais após um ano de treinamento de rúgbi em cadeira de rodas. Participaram dezoito voluntários, nove do grupo de lesados medulares (GL) e nove sem lesão medular fazendo parte do grupo controle (GC). Do GL, sete voluntários foram acompanhados durante um ano de treinamento. Através das curvas de volume em função do tempo, calculou-se o coeficiente de variação das curvas no tórax superior (TS), tórax inferior (TI), abdome superior (AS), abdome inferior (AI), representando a mobilidade do toracoabdominal, em volume corrente (VC) e em capacidade vital (CV). As comparações e interações entre os fatores: grupos e compartimentos toracoabdominal foram testadas utilizando ANOVA two way e para comparar as diferenças entre os coeficientes de variação GL antes e depois do treinamento foi aplicado um teste t pareado, considerado nível significância de p<0.05 para todos os testes. Em VC não houve diferença significativa quando o GC foi comparado ao GL.Em CV, os valores dos compartimentos TS, TI e AS do GC foram significativamente maiores que os valores dos mesmos compartimentos do GL. No GL, os valores do coeficiente de variação do compartimento do TS foram significativamente menores que os valores do AI; No GL antes e depois de treinamento, a mobilidade do TS foi significativamente maior na condição pós treinamento comparada a pré treinamento. Na terceira parte, comparou-se a espirometria com análise cinemática da respiração. Foram analisadas de maneira descritiva as variáveis: as curvas de volume em função do tempo, os valores médios e de desvio-padrão dos ciclos respiratório, os valores máximos dos ciclos respiratórios, diferença entre os valores máximos e a correlação de Pearson entre os valores das curvas medidos pelo dois métodos. Existiu alta correlação entre as medidas de volume feita pela espirometria e cinemetria, contudo, os valores máximos de volume toracoabdominais calculados pela análise cinemática mostram uma tendência a serem inferiores aos valores de volumes obtidos pela espirometria. O treinamento de rúgbi em cadeira de rodas, pode melhorar a função pulmonar e mobilidade toracoabdominal de lesados medulares / Abstract: This work aimed to study the effect of a year of training in wheelchair rugby on pulmonary function and thoracoabdominal mobility of tetraplegics by spirometry and kinematic analysis. This study wasdivided into three parts. In the first part, seven tetraplegics underwent spirometry before and after attending a year of wheelchair rugby training. All Subjects presented reduced lung function compared with the predicted values. There was a significant increase in forced vital capacity (p= 0,01), first minute forced expiratory volume (p= 0,02), and maximal voluntary ventilation (p= 0,03. The regression analysis between total training time and spirometric variables showed that players with longer training had higher lung function values (r² =0,93e 0,58, p =0,0004 e 0,004). In the second part, we studied the kinematical analysis of thoracoabdominal mobility of wheelchair rugby practitioners and the differences in the mobility of thoracoabdominal compartments after a year of training. Nine tetraplegics participated in the training group (TG) and nine participantswithout spinal cord injury took part as the control group (CG). Seven volunteers of the TG were monitored for one year of training. From the volume curves as function of time we calculated the coefficient of variation of the curves in the superior thorax (ST), inferior thorax (IT), superior abdomen (SA) and inferior abdomen (IA), which representied the mobility of the thoracoabdominal compartment in the vidal volume (VT) and vital capacity (VC). Comparisons and interactions between the factors groups and thoracoabdominal compartments were tested using two-way ANOVA. To compare the differences between the coefficients of variation of TG before and after training, it was applied a paired t test, considering p <0.05 for all tests. in the variable VT showed no significant difference when the CG was compared to TG. In VC, the values of the compartments ST, IT, SA to GC were significantly higher than the values of the same compartments in TG. In TG, the coefficient of variation of TS was significantly lower than the values of IA. On TG before and after training, the mobility of ST was significantly higher to the post training results compared to pre training. In the third part, we compared spirometry with kinematical analysis of the chest wall. We analyzed the descriptive variables: volume curves as a function of time, the mean and standard deviation of the respiratory cycles, the maximum values of the respiratory cycles, the difference between the maximum and Pearson correlation between the values of curves measured by the two methods. There was high correlation between the volume measurements obtained by spirometry and kinematics, however, the maximum thoracoabdominal volume calculated by kinematical analysis showed a tendency to be lower than the values of the volumes obtained by spirometry. The wheelchair rugby training can improve pulmonary function and thoracoabdominal mobility of people with spinal cord injury / Mestrado / Biodinamica do Movimento Humano / Mestre em Educação Física

O presente estudo teve como objetivo comparar as medições direta e indireta do Consumo Pico de Oxigênio (VO2pico) no teste de campo contínuo e incremental Octagon Multi-Stage Test (OMFT) bem como, correlacionar os valores obtidos no teste contínuo e incremental no ciclo-ergometro de braço (EB). Participaram desse estudo 8 atletas tetraplégicos praticantes de Rugby em cadeira de rodas. Os atletas inicialmente realizaram a avaliação antropométrica para o cálculo do índice de massa corporal (IMC) e percentual de gordura (%G) em seguida foram submetidos ao teste de campo incremental (OMFT) com a utilização do analisador de gás portátil K4b2 Cosmed para mensuração direta do VO2pico. Após 72 horas os mesmos atletas realizaram o teste contínuo e incremental no EB para obtenção dos valores de VO2pico. Pré e pós-testes foram mensurados os valores de Frequência Cardíaca (FC), Concentração de Lactato ([Lac]), Consumo de Oxigênio (VO2) e percepção Subjetiva de Esforço (PSE). Além disso, no teste de campo (OMFT) foram coletados os dados de distância total percorrida, estágio final e número de voltas realizadas variáveis para mensuração indireta do VO2pico. Para os valores de VO2pico, observou-se que no EB os valores de média do grupo foi de 17,8±6 ml/kg/min, enquanto que para o teste OMFT foram de 21,9±5,2ml/kg/min pela mensuração direta e 24,8±3,3ml/kg/min para a mensuração através da equação de predição pré-estabelecida, a FCmax foi de 129,1±24bpm no EB e de 127,8±26bpm no OMFT. Já a PSE foi de 8,2±1,03 no EB e de 6,5±2,2 no OMFT. Através do calculo de correlação entre as mensurações de VO2pico, observou-se alta correlação (r=0.86) entre as mensuração do OMFT direta e indireta com nível de significância de p<0.05 e através do teste de Bland-Altman foi observada a concordância entre os métodos com LIC95% variando de -2,8 a 8,5. O teste OMFT apresenta validade para mensuração da Potência Aeróbia em atletas com tetraplegia, porém, observa-se a necessidade de reajustes no protocolo para que os resultados encontrados sejam de fato mais próximos à realidade dos atletas com tetraplegia, possibilitando maior controle dos resultados obtidos e a prescrição da intensidade de exercícios, evitando assim, lesões devido à sobrecarga do treinamento / Abstract: Evaluation of Aerobic Power in Spinal Cord Injury athletes as an indicator of maximum aerobic exercise tolerance is an important area of interest of sports performance. The present study aimed to compare the direct and indirect measurements of peak oxygen consumption (VO2peak) in field testing continuous and incremental Octagon Multi-Stage Test (OMFT) and to correlate the values obtained in the test continuous incremental in cycle-arm ergometer (EA). Eight athletes of the Wheelchair Rugby participated in this study. These athletes initially underwent anthropometric measurements for calculating the Body Mass Index (BMI) and percent body fat (%BF). After were submitted to field test (OMFT) with the use of portable gas analyzer K4b2 Cosmed for measurement direct of the VO2peak. After 72 hours the same athletes performed the test continuous incremental in EA to obtain the values of VO2peak. Pre and post-test values have been measured heart rate (HR), lactate concentration ([Lac]), oxygen consumption (VO2) and perceived exertion (PE). Moreover, the field test (OMFT) data were collected from total distance traveled, stage, and number of turns. Variables to measurement indirect of VO2 peak. For the VO2peak values, it was observed that the values of the EA group mean was 17.8 ± 6ml/kg/min, whereas for the test OMFT were 21.9 ± 5.2 ml/kg/min by direct measurement and 24.8 ± 3.3 ml/kg/min for measurement prediction equation by pre-established, HRmax was 129.1 ± 24bpm in EA and 127.8 ± 26bpm in OMFT. Already the PSE was 8.2±1.03 in EA and 6.5±2.2 in OMFT. By calculating the correlation between the measurements of VO2peak, there was a high correlation (r = 0.86) between the measurement of direct and indirect OMFT with a significance level of p <0.05 and by Bland-Altman concordance was observed between methods with varying LIC95% from -2.8 to 8.5. The OMFT shows validity for measuring Aerobic Power in athletes with tetraplegia; however, there is a need for adjustments in the protocol so that the results are actually closer to the reality of athletes with tetraplegia, enabling greater control of the results and prescription of exercise intensity, thus avoiding injury due to overload training / Mestrado / Atividade Fisica Adaptada / Mestre em Educação Física

A amostra foi composta de dez (10) tetraplégicos do sexo masculino com média de idade de 29,6 ± 6,5 anos. As coletas foram realizadas na UNICAMP, com a aprovação do Comitê de Ética em Pesquisa sob-protocolo nº 276/2010. Foram realizadas avaliações antropométricas. A potência aeróbia (PA) foi estimada por um teste máximo de quadra com duração de 12 minutos. A Pressão arterial (PAS) verificada pelo método auscultatório e o registro da variabilidade da PAS (VPAS) através do equipamento Finometer® (Finapress©). Avaliações da VFC foram realizadas com os sujeitos sentados nas cadeiras próprias (repouso, estresse mental e exercício). O Stroop Test foi utilizado como teste de estresse mental (TEM). Para o registro de informações da VFC foi usado o frequencímetro modelo RS800CX-POLAR© e posteriormente foi utilizado o software da Polar© para análise dos dados. Os dados foram apresentados em média±desvio padrão. Para análise estatística foi utilizado o software INSTAT®. Valores de p<0,05 foram considerados significativos para diferenças entre situações de avaliação. O tempo de lesão medular foi de 7,5 ± 4,1 anos. Quanto à massa corporal e estatura dos sujeitos, foi verificada média de 64,5 ± 6,2 kg e 1,75 ± 0,09 m. O índice de massa corporal foi de 21 ± 1,4 kg/m2. Já o percentual de gordura (DXA) foi de 21± 5,4%. O valor médio da distância percorrida no teste de 12 min, para a estimativa da PA foi de 1579,5 ± 439,1 m. O valor médio para a PA estimada correspondeu a 18,03 ± 8,1 ml/kg/min-1. Valores de FC e PAS foram significativamente maiores ao final do teste de 12 min quando comparados aos valores de repouso e recuperação. Resultados de FC ao longo do teste de estresse mental revelaram-se maiores que os valores de FC iniciais do registro. A PAS não apresentou diferenças entre as avaliações de repouso e estresse mental, assim como os valores de VFC não apresentaram diferenças significativas nestas situações. Valores do balanço autonômico da VFC também não apresentaram diferenças quando comparado valores iniciais e no teste de estresse mental (BF, AF e BF/AF). Já em exercício a VFC apresentou diferenças, assim como os valores de BF, AF e BF/AF quando comparado aos valores pré e pós exercício. A VPAS apresentou-se reduzida pós exercício físico, assim como a PASist e o índice de BF quando comparados aos valores pré exercício físico. Estes resultados indicam que a amostra estudada apresenta potência aeróbia dentro da normalidade para esta população. O % de gordura foi menor do que outros estudos com tetraplégicos. Ocorreram alterações durante o exercício físico nos componentes da VFC e VPAS semelhantes aos de outros estudos com tetraplégicos - (repouso x TEM x pós exercício físico). Há indícios de menores prejuízos neste grupo estudado em relação aos danos no controle autonômico da circulação, provavelmente por esta amostra participar de programa de treinamento físico / Abstract: The purpose of this work was to evaluate the autonomic and the cardiovascular responses in people with spinal cord injury (PLME) the players of Wheelchair Rugby (RCR) in different situations. The sample was composed of ten (10) tetraplegics male. The samples were collected in Campinas, with the approval of the Committee of Ethics in the Research with the protocol 276/2010. In this work was performed anthropometric evaluation. The aerobic power (AP) was estimated by a max court test that didn't exceed 12 minutes. The blood pressure (BP) verified by auscultation and registration of the BP variability (BPV) through an equipment called Finometer® (Finapress©).The evaluation of heart rate variability (HRV) were made with the individuals sitting on their chairs (rest, mental stress test and exercise). The Stroop Test was used as a test of mental stress. For recording of information of the HRV was used frequency counter model RS800CX-POLAR© and afterward was used Polar© software for data analysis. The data were expressed as average±standard deviation. To the statistical analysis was performed using the INSTAT® software. p values<0.05 were considered statistically significant differences between the situations of evaluation. The average age of the individuals was 29.6 ± 6.5 years old and the time of spinal cord injury was 7.5± 4.1 years. As for weight and height of them, there was an average of 64.5 ± 6.2 kg and 1.75 ± 0.09 m. The body mass index was 21 ± 1.4 kg/m2. The fat percentage (DXA) was 21 ± 5.4%. Results revealed that the test for 12 min, the distance rode to the PA estimate was 1579.5 ± 439.1 m. It was verified that the estimated value of AP is 18.03 ± 8.1 ml/kg/min-1. The HR and the BP values were significantly higher at the end of the test 12 min when compared to the values of resting and recovery. The results of FC along the mental stress test, proved to be larger than the values of initial HR of the record. The BPV did not show differences between the evaluations of rest and mental stress, as well as the values of HRV were not significantly different in these situations. Values of the autonomic balance of the HRV also showed no differences when compared to initial values and mental stress test (LF, AF e LF/HF). In the exercise the HRV presented discrepancies as well as the heart rate variability showed differences as well as the values of LF, HF e LF/HF when compared to pre and post exercise. The VBP presented the reduced as well as SBP and the values of BF compared before and after exercise. These results indicate that the sample presents aerobic power within the normal range for this population. The percentage of fat was lower than other studies with tetraplegics. Changes during exercise in HRV components and BPV similar to other studies with tetraplegics - (resting x TEM x post exercise). We can still consider that exist evidence of minor damage in relation to damage to the autonomic control of circulation, probably because this sample participate in physical training program / Doutorado / Atividade Fisica, Adaptação e Saude / Doutor em Educação Física

The intra- and inter-rater reliability of manual muscle testing in the new hand classification of wheelchair rugby

van Niekerk, Yvette January 2017 (has links)
Introduction: Before 2015 the hand classification in wheelchair rugby consisted of non-sport specific tests. The hand classification was not in accordance with the classification code introduced by the International Paralympic Committee in 2003. In 2015, the newly revised wheelchair rugby classification manual was released, containing the revised wheelchair rugby hand classification. Hand tests that were not functional sport-specific tests were removed from the bench test in wheelchair rugby classification. Lumbrical, interossei and thumb opposition manual muscle testing were added to the bench test in wheelchair rugby classification. On both national and international levels of classification, classifiers verbalised their uncertainty to their fellow panel members regarding their hand placement on the athlete’s hand and interpretation of the manual muscle testing of the hand that was observed and tested. This justified reliability testing of the new hand classification. Aim: The aim of this study was to determine the intra and inter-rater reliability of the manual muscle testing in the new hand classification of wheelchair rugby. Study design: This study followed a quantitative non-experimental, cross-sectional design. Method: The raters who took part in the study were active international wheelchair rugby classifiers from all over the world. The raters received an electronic questionnaire consisting of biographic information and three videos repeated two times. Each video showed an athlete’s hand being classified by a classifier. The raters had to give a manual muscle test grade for each subject (muscle) tested in each video by using tick boxes. The manual muscle test grades that could be given were: 0-1, 2, 3 and 4-5. The first three raters in each international wheelchair rugby classification level who completed the questionnaire were used for the data analysis. Data Analysis: The statistician used the two way model for the ICC in which each subject was rated by the same raters to determine the absolute agreement for each objective. The Medcalc program was used. To indicate the strength of agreement the ranges provided by Landis and Koch (1977) were used: 0.0 – 0.2 slight, 0.21 – 0.4 fair, 0.41 – 0.6 moderate, 0.61 – 0.8 substantial and 0.81 – 1.00 almost perfect. Conclusion: Raters one, two, five, seven, eight and nine’s intraclass correlation coefficient values fell between 0.81-1.00 which is descriptive of almost perfect levels of intra-rater reliability. Raters three, four and six’s intraclass correlation coefficient values fell between 0.61-0.80 which is descriptive of substantial levels of intra-rater reliability. However, none of the raters scored 100% when accuracy was determined. All three levels had intraclass correlation coefficient values which is descriptive of almost perfect levels of intra-rater reliability within each level. Level 2, 3 and 4 classifiers had intraclass correlation coefficient values between 0.81- 1.00 which is descriptive of almost perfect levels of inter-rater reliability when the manual muscle testing grades for the first and repeated videos were compared. Across all nine raters there was a high intraclass correlation coefficient value which was descriptive of almost perfect inter-rater reliability. The accuracy in each level and across all nine raters was low. Finger extensors, thumb abductor and thumb flexor showed intraclass correlation coefficient values between 0.41-0.6 which is descriptive of moderate levels of intrarater reliability. The only subjects (muscles) that were graded accurately when compared to a memorandum were subjects with a manual muscle test grade 0-1 and 4-5. Most of the accurate manual muscle test grades were for athlete two in the video footage. Athlete two was classified as having a 2.0 hand. / Dissertation (MOccThe)--University of Pretoria, 2017. / Occupational Therapy / MOccThe / Unrestricted

Vztah kvality života a psychické odolnosti a vytrvalosti u hráčů parahokeje a vozíčkářského rugby / Relationship of quality of life and hardiness, relisience and grit in parahockey and wheelchair rugby players

Jiskrová, Markéta January 2020 (has links)
anglicky Objectives: This thesis aims to investigate whether we can predict the general and sport- specific quality of life of athletes with physical disabilities based on selected positive psychological constructs (resilience, hardiness and grit). Method: Forty players of para ice-hockey and wheelchair rugby (of which only two were women) underwent this study. The data were obtained by a questionnaire, compiled by Professor Martin from Wayne State University, which contains six parts: general information, life satisfaction, grit, resilience, sports engagement and hardiness. The "translation and reverse translation" method was used to translate the questionnaire. We used the statistical program IBM SPSS 2200 to analyze the obtained data. Results: Life satisfaction can be best predicted on the basis of hardiness (R = 0.686), but also resilience (R = 0.496) and grit (R = 0.340). We can predict sports engagement only based on resilience (R = 0.374). We recommend searching for other possible positive constructs that could better predict sports engagement. Key words: quality of life, sport engagement, life satisfaction, resilience, hardiness, grit, para ice hockey, wheelchair rugby
