[en] Hurdles and sprint races take place on athletics tracks, on a surface made of materials known as tartan or mondo, which provide a certain degree of reactivity. There is a wide variety of events involving both disciplines both in daily training and in competitions from an incredibly early age. The hurdles test, biomechanically speaking, should differ as little as possible from running without hurdles. This means that the athlete should run the race at a slower speed after each hurdle and have a technique that is as flat as possible, without raising the hip level. During the race, the athlete must attack the hurdles with the same leg in a cyclical manner, which results in a possible increase in tissue strees in one of the lower limbs. After analysing the subject of the study, doubts arose about the injury of the test in comparison to the sprint, the injury of the spikes or the difference in the presence of pathologies in the foot that lands after crossing the hurdles. The current literature was unable to answer these questions. Hypothesis and objectives. The hypothesis of the study is to find out if hurdling involves an increase in the incidence of foot pathologies compared to sprinting without hurdles. Therefore, the main objective of the study will be to determine whether hurdles are more harmful than sprinting. Methodology This is a prospective cohort study to compare the incidence of pathologies in athletes from the Autonomous Community of Galicia in two groups, one of sprint athletes and the other of hurdles athletes. A sample of ninety-seven athletes will be selected. The participants will fill in a form and then a measurement of anthropometric values will be carried out in the training place, where values will be obtained to compare and relate with the results obtained on the form.

[gl] As carreiras valadas e as de velocidad lévanse a cabo nas pistas de atletismo, sobre unha superficie feita cuns materiais coñecidos como tartán ou mondo, os cuales proporcionan certo grao de reactividade. Hai una amplia variedade de probas que involucran a ambas disciplinas tanto nos entrenamientos diarios como nas competición dende idades temperás. A proba de valados, biomecánicamente falando, debe diferir pouco da carreira sen vallas. Esto tradúcese en que o atleta disputa a carreira perdendo pouca velocidade tras o paso de cada valla e cunha técnica o máis a ras posible, sen elevar a cadeira. No transcurso da proba o atleta debe atacar as vallas coa mesma perna de forma cíclica, o que se traduce no aumento do estrés tisular sobre un dos membros inferiores. Tras o análise do tema de estudo, surxiron dúbidas sobre a lesividade da probra en comparación coa velocidade lisa, a lesividade dos clavos ou a diferencia na presencia de patoloxías no pé que aterriza no chan tralo paso da valla. A bibliografía actual non esclareceu as cuestións. Hipótese e obxectivos A hipótese do estudio é conocer se a carreira de valados implica un aumento da incidencia de patoloxías no pé en comparación coa velocidade sen vallas. Por iso, o obxectivo principal do estudo será determinar se as probas de valados son máis lesivas que as probas de velocidade lisa. Metodoloxía. Trátase dun estudo de cohortes de tipo prospectivo no que se vai comparar a incidencia de patoloxías en atletas da Comunidade Autónoma de Galicia de dous grupos, un de atletas de velocidade e outro de valados. A mostra é de 97 deportistas. Os participantes cumplimentarán un formulario e despois se analiza unhas valores antropométricas no lugar de adestramento, obtendo valores para comparar e relacionar nos resultados
