Abstract(s)
Apesar das diversas similitudes inerentes ao futebol e ao futsal, cada modalidade apresenta características próprias em termos de habilidades e tipologia de esforço. Posto isto, o objectivo do presente estudo é traçar o perfil muscular de jogadores de ambas as modalidades relativamente aos músculos extensores (quadricipede) e flexores (isquio-tibiais) da articulação do joelho, através da análise do peak torque, trabalho e relação agonista/antagonista. Para tal, participaram no estudo 16 atletas, sendo 8 de futebol e 8 de futsal. A média de idade dos jogadores foi de 23,5 anos_ Os resultados encontrados neste estudo demonstram que não existem diferenças significativas entre membro inferior dominante e não dominante para cada das variáveis estudadas_ Observam-se diferenças significativas em termos de Peak torque aos 60°/s entre os atletas das duas modalidades estudadas, assim como do Total work do MID à mesma velocidade. Os resultados obtidos aos 180°/s sugerem superioridade em termos de Peak torque do MIE para os atletas de Futebol e, para a mesma velocidade, os atletas de Futebol também apresentam maior capacidade de produção de trabalho total. Para o RI/Q não é de salientar diferenças significativas, deste modo, todos os valores encontrados situam-se entre 50 a 60% a baixa velocidade angular, sendo considerados valores normais. Em termos globais, os atletas de futebol deste estudo parecem demonstrar uma relativa superioridade quando comparados com atletas de futsal no que concerne ao perfil muscular extensor e flexor do joelho.
Despite several similarities inherent to football and futsal, each modality has its own characteristics in terms of skills and type of effort. This way, the aim of this study is to perform a muscular profile of the players of both modalities for the extensor muscles (quadriceps) and flexors muscles (ischiotibialis) of the knee joint through the analysis of peak torque, total work and agonist / antagonist ratio, 16 athletes took part in the study, 8 of each modality. The mean age of the group was 23.5 years_ The results found in this study demonstrate that there are no significant differences between dominant and non-dominant leg for each of the studied variables. it was observed significant differences in terms of peak torque at 60 Vs between the athletes of the two modalities, as well as the total work of the right leg at the same speed. Results at 180°/s suggest some degree of superiority in terms of left leg peak torque for football athletes. Football athletes also seems to present better skills for total work production, at the same speed_ For the agonist/antagonist ratio, there is no significant differences, thus all values were found between 50-60%, at low angular velocity, what can be considered as normal. Overall, the soccer athletes in this study appear to demonstrate a relative superiority when compared to futsal players in relation to the muscle profile of the knee.
