Efeito do Uso de Coroas Não Circulares Sobre o Desempenho de Ciclistas: Revisão de Literatura

Objetivo: Verificar a influência do uso de coroas-não-circulares (CNC) e coroas-circulares (CC) sobre os parâmetros biomecânicos, fisiológicos e no desempenho de ciclistas. Métodos: Após busca nas principais bases de dados (PubMed, SpringLink, ScienceDirect, ScienceReserch e Google Scholar), foram encontrados 31 artigos relacionados ao tema, dos quais 13 foram selecionados para uma análise aprofundada. Três artigos estudaram a CNC Biopace®, cinco a CNC Osymetric®, cinco a CNC Q-Ring® e três estudaram outros tipos de CNC. Resultados: Nove dos 13 artigos revisados apresentaram em seus resultados algum tipo de interferência nas variáveis analisadas. Conclusão: O uso de CNC apresentou efeito positivo, principalmente em atividade anaeróbia, com é o caso de modalidades como BMX, mas ainda existe pouca comprovação da melhora no desempenho em atividades aeróbias. Outras alterações foram, a redução do momento de força sagital durante extensão do joelho e o aumento de força tangencial nos pedais.
