Abstract(s)
Introdução: A flexibilidade está diretamente relacionada com o alongamento muscular, sendo que quanto maior a sua capacidade de alongamento, maior a amplitude de movimento de uma articulação. O alongamento está associado ao ganho de amplitude de movimento e está inerente ao exercício excêntrico. Objetivo: avaliar a influência do fortalecimento muscular excêntrico na flexibilidade do quadríceps, em dançarinas de Hip-Hop. Metodologia: dois momentos de avaliação da flexibilidade do quadríceps bilateralmente, M0 e M1 (antes e após aplicação do protocolo, respetivamente), utilizando o Teste Thomas, Passive Knee Flexion Test e Kneeling Test. Aplicação de um protocolo de fortalecimento excêntrico constituído pelos seguintes exercícios: squat, squat jump, lunge, drop jump e step down. Resultados: No que se refere à amostra constatamos diferenças estatisticamente significativas em três parâmetros: peso, membro dominante e membro de apoio. Encontraram-se diferenças estatisticamente significativas quanto à perimetria no PKF e Kneeling test do membro inferior direito no grupo experimental e no Teste de Thomas e PKF do membro inferior direito e Kneeling Test do membro inferior esquerdo do grupo controle. Conclusões: o fortalecimento excêntrico influenciou diretamente o trofismo do quadríceps. Na flexibilidade não se obtiveram certezas se a sua melhoria foi devida ao programa aplicado.
Introduction: flexibility is directly related to muscular lengthening. So, if the muscle achieves high stretching capacity, a bigger range of motion will be possible. Lengthening of a muscle is associated with an increase in range of motion and is inherent to eccentric exercise. Objective: evaluate the influence of an eccentric exercise strengthening program on quadriceps flexibility in Hip-hop dancers. Methodology: two evaluation moments of quadriceps flexibility bilaterally, M0 and M1 (before and after applying the program, respectively), using the Thomas Test, Passive Knee Flexion Test, and Kneeling Test. Implementation of an eccentric strengthening protocol consisting of the following exercises: squat, squat jump, lunge, drop jump, and step down. Results: concerning the sample, we noted statistically significant differences in three parameters: weight, dominant lower limb, and support lower limb. Statistically significant differences were found in terms of perimetry of the PKF and Kneeling test of the right lower limb in the experimental group and in the Thomas test and PKF of the right lower limb, and in the Kneeling test of the left lower limb in the control group. Conclusions: eccentric strengthening directly influenced the trophism of the quadriceps. There was no clear evidence to conclude if the improvement in flexibility was due to the program applied.
