O presente relatĂłrio surge no Ăąmbito da unidade curricular âDissertação/Trabalho de Projeto/estĂĄgioâ inserida no plano de estudos do curso de Mestrado em Engenharia MecĂąnica, da Escola Superior de Tecnologia e GestĂŁo, do Instituto PolitĂ©cnico de Bragança.
A prĂĄtica da corrida conquista cada vez mais adeptos, ocorrendo um aumento de procura dos locais para a prĂĄtica. Esse aumento pode levar a um maior nĂșmero de lesĂ”es nos membros inferiores. Uma das causas potenciais dessas lesĂ”es Ă© a corrida em pisosdistintos, o que pode ter consequĂȘncias no desempenho biomecĂąnico da corrida.
A dissertação tem como objetivo principal analisar a influĂȘncia da rigidez do solo na biomecĂąnica da corrida. Para isso, a amostra deste estudo Ă© constituĂda por vinte e oito participantes, sendo catorze do sexo masculino e catorze do sexo feminino. Um participante de cada sexo realizou um teste piloto permitindo a anĂĄlise do set-up e da distĂąncia a ser percorrida.
Os ensaios foram realizados em trĂȘs tipos de piso: piso betuminoso, pista de atletismo com piso em tartan e pavilhĂŁo desportivo com chĂŁo de madeira e caixa de ar. Na recolha de dados biomecĂąnicos, utilizamos dois mĂ©todos: a cinemĂĄtica e a cinĂ©tica. Esta Ășltima foi dividida em dois subcapĂtulos: o modelo de massa e molas, e a anĂĄlise de força, potĂȘncia e velocidade.
Para a recolha de dados, recorremos às microgates e a filmagens, utilizando o software apropriado, Kinovea, para a anålise das nossas variåveis. A comparação do desempenho
biomecùnico em relação aos diferentes pisos foi realizada por meio de ensaios de LFWD, feitos no ponto zero da corrida, a meio dos 25 metros e no fim dos 25 metros, como uma carga de 15 kg para estudar o módulo de deformabilidade do solo.
Para a anĂĄlise dos dados da biomecĂąnica da corrida, utilizamos um software para a anĂĄlise descritiva, ANOVA e post-hoc, comparando os resultados obtidos nos trĂȘs pisos diferentes em que os ensaios foram realizados.
ConcluĂmos que o melhor piso, devido Ă sua rigidez seria o tartan. No entanto, alguns dos valores nĂŁo foram os melhores de acordo com a literatura. Isso pode justificar-se pelo facto de que, apesar de todos os participantes praticarem algum tipo de exercĂcio fĂsico, nĂŁo tinham tĂ©cnica de corrida.
This report is part of the âDissertation/Project Work/Internshipâ curricular unit included in the syllabus for the Master's degree course in Mechanical Engineering at the School of Technology and Management of the Polytechnic Institute of Bragança. The practice of running is gaining more and more fans, with an increase in demand for places to practice it. This increase can lead to a greater number of lower limb injuries. One of the potential causes of these injuries is running on different surfaces, which can have consequences for the biomechanical performance of running. The main objective of this dissertation is to analyze the influence of ground stiffness on the biomechanics of running. To this end, the study sample consisted of twenty-eight participants, fourteen male and fourteen female. One participant from each gender took part in a pilot test, allowing the set-up and the distance to be covered to be analyzed. The tests were carried out on three types of surface: tarmac, an athletics track with a tartan floor and a sports hall with a wooden floor and an air box. We used two methods to collect biomechanical data: kinematics and kinetics. The latter was divided into two subchapters: the mass and spring model, and the analysis of force, power and speed. For data collection, we used microgates and filming, using the appropriate software, Kinovea, to analyze our variables. The comparison of biomechanical performance in relation to the different surfaces was carried out by means of LFWD tests, carried out at the zero point of the race, halfway through the 25 meters and at the end of the 25 meters, with a load of 15 kg to study the modulus of deformability of the ground. To analyze the data on the biomechanics of running, we used software for descriptive analysis, ANOVA and post-hoc, comparing the results obtained on the three different surfaces on which the tests were carried out. We concluded that the best surface, due to its rigidity, was tartan. However, some of the values were not the best according to the literature. This could be due to the fact that, although all the participants practiced some kind of physical exercise, they had no running technique.
