Yanci, Irigoyen, J. (2015). Pesquisa Descritiva Correlacional ou Qualitativa: Análise cinemática e diferenças bilaterais na técnica de pedalada de ciclistas profissionais. Pensar en Movimiento: Revista de Ciencias del Ejercicio y la Salud, 13(2), 1-12. Os objetivos deste estudo foram, por um lado, descrever a máxima flexão e extensão do joelho e do calcanhar alcançadas na fase de pedalada por ciclistas profissionais e, por outro, comparar as diferenças nestas angulações entre a extremidade inferior direita e esquerda. Neste estudo participaram 13 ciclistas pertencentes a uma equipe profissional que assiduamente participava na Volta Ciclista na Espanha. Todos os participantes tinham uma experiência superior a 10 anos de ciclismo. No presente estudo realizou-se a medição da longitude das bielas, altura e o retrocesso do selim das bicicletas dos ciclistas. Da mesma forma realizou-se a análise cinemática em 2D da pedalada com a finalidade de avaliar as angulações do joelho e do calcanhar. Não foram encontradas diferenças significativas entre a perna direita e esquerda na angulação da flexão nem extensão do joelho nem na flexão do calcanhar na pedalada dos ciclistas. Entretanto, contrariamente a outros estudos, sim foram encontradas diferenças na angulação da extensão do calcanhar (p < 0,05, diferença médias = 14,53 %, d = 0,37, baixo) entre as duas pernas. Em futuras pesquisas poderia resultar interessante complementar a análise cinemática com o cinético para, assim, observar se as diferenças nas angulações são acompanhadas de diferenças na força aplicada por cada uma das pernas.
