“…Recently, the role of the muscle has been more emphasized for maintaining the stability of the vertebrae. Comerford and Mottram 13) highlighted the importance of the characterized and integrated action of the muscle system, and the recognition of its relevance in maintaining the optimum functions and stability of an exercise system has been increasing.…”

Abstract.[Purpose] The aim of this study was to determine the optimal knee joint angle for minimizing cervical muscle tension and maximizing the muscle activity of the trunk during the bridging exercise for trunk stabilization.[Subjects] The subjects of this study were 45 healthy adults in their 20s and 30s.[Methods] The bridging exercise in this study included four forms of the exercise having knee joint flexion angles of 120°, 90°, 60°, and 45°. The posture of the bridging exercise was as follows. To prevent the increase of lumbar hyperlordosis during the bridging exercise, the exercise was practiced after maintaining the lumbar neutral position in the posterior pelvic tilting exercise.[Results] During the bridging exercise, muscle activity increased as the flexion angle decreased. For the knee joint flexion angle of 120°, muscle activity was 102.88 ± 0.69. It was 102.61 ± 0.69 for 90°, 105.57 ± 0.85 for 60°, and 106.24 ± 0.88 for 45°. According to the post hoc results, muscle activity was significantly higher for 60° and 45° than for 120° and 90°.[Conclusion] The knee joint angle affected the muscle activity of the neck muscle. The greater the knee joint angle was, the lower the load placed on the neck muscle. In contrast, the load increased as the knee joint angle decreased. In addition, the muscle activity of the neck muscle and trunk muscle increased as the knee joint angle decreased.

“…The ideal pattern was believed to be characterized by the initial activation of the gluteus maximus, followed by the hamstring and erector spinae muscles 1,2 . In the present study, however, this pattern was not observed in either of the evaluated groups.…”

“…Relationships between movement patterns and dysfunctions have been studied 1,2 and movement is considered to be a system, which depends on the appropriate functional and interactions between several elements: basic systems (muscular and skeletal), modulator system (nervous), and the biomechanical and support systems 2 . Each element plays an important role in movement production and can be, in turn, be modified due to the adaptative physiological responses of the tissues 3 .…”

Influences of the extensor portion of the gluteus maximus muscle on pelvic tilt before and after the performance of a fatigue protocolInfluência da porção extensora do músculo glúteo máximo sobre a inclinação da pelve antes e depois da realização de um protocolo de fadiga AbstractIntroduction: There is a lack of data in the literature for determining the influences of the extensor portion of the gluteus maximus muscle on pelvic tilting and, thus, on lumbar stability. Objectives: To assess the influences of the extensor portion of the gluteus maximus muscle on pelvic tilt. Methods: Ten healthy young subjects were recruited, with a body mass index (BMI) below 24.9 kg/m 2 and leg length discrepancy below 1 cm. The BMI, pelvic perimeter and lower-limb lengths were assessed and, subsequently, the degrees of hemi-pelvic tilt and asymmetry between them were analyzed using lateral view photographs of the subjects in a standing position, using SAPO (Software for Postural Assessment). Next, fatigue was induced in the extensor portion of the gluteus maximus muscle on the dominant side, and after that the hemi-pelvic tilt and the asymmetry between the hemi-pelvises were reassessed. The Pearson r and Student t tests were conducted at the significance level of α=0.05. Results: There were no significant correlations between the confounding variables and asymmetry of the hemi-pelvic angles. There were significant changes in the hemi-pelvic angle of the dominant side (t=3.760; p=0.004). Conclusions: Fatigue in the extensor portion of the gluteus maximus muscle can generate increases in the tilt angle of the ipsilateral pelvis.Key words: gluteus maximus; fatigue; pelvic tilt. ResumoIntrodução: Há carência na literatura de dados que determinem qual a influência da porção extensora do músculo glúteo máximo na inclinação da pelve no plano sagital e, portanto, na estabilidade lombar. Objetivos: Verificar a influência da porção extensora do músculo glúteo máximo sobre a inclinação da pelve. Métodos: Foram recrutadas 10 voluntárias jovens, saudáveis, com índices de massa corpórea (IMC's) menores que 24,9 kg/m 2 e com dismetria real de membros inferiores (MMII) inferior a 1 cm. Foram avaliados o IMC, o perímetro pélvico e o comprimento dos MMII e, posteriormente, os graus de inclinação das hemipelves e a assimetria entre elas pela análise de uma fotografia em perfil ortostático usando o SAPO (Software para Avaliação Postural). Em seguida, a porção extensora do músculo glúteo máximo do lado dominante foi induzido à fadiga, após a qual foram determinadas novamente a inclinação das hemipelves e a assimetria entre elas. Testes de Pearson r e teste t de student foram realizados no nível de significância α=0,05. Resultados: Não houve correlação entre as variáveis de confusão e a assimetria dos ângulos das hemipelves. O ângulo da hemipelve apresentou modificação significativa do lado dominante (t=3,760; p=0,004). Conclusões: A fadiga da porção extensora do músculo glúteo máximo pode gerar um aumento do ângulo de inclinação da pelve homolatera...
