ABSTRACT

The thigh, hip and lower back have been common sights of injuries in Bharatanatyam dancers. The study investigates the relationship between muscular activity levels of the leg and pelvic posture during araimandi. Electromyography(EMG) and postural analysis were used to measure the activation in three selected muscle groups(Quadriceps, Hamstrings and Gluteus Maximus) and the pelvic posture study in seven dancers. Depending on the training level, EMG tracings indicated that dancers indicated higher activation of the Quadriceps or Gluteus Maximus. The Hamstrings remained the least activation muscle in all dancers. Thus, due to the difference in activation levels, muscular imbalance may occur in Bharatanatyam dancers. Further, anterior pelvic tilt was the most commonly observed misalignment. The movement biomechanics, faulty movement adaptation, and pelvic orientation primarily influenced muscle activation patterns. The dancer’s training level and compensatory strategies influenced the pelvic posture while performing the araimandi movement. Although both muscular imbalance and pelvic alignment influenced each other, the pelvis’s orientation significantly affected the leg muscles’ activation patterns. Thus, the study established a relationship between muscular imbalance and pelvic alignment. Further, applications of these findings to dance training have been discussed.

摘要

大腿、臀部和腰部是婆罗多舞者常见的受伤部位。该研究调查了 araimandi 期间腿部肌肉活动水平与骨盆姿势之间的关系。使用肌电图 (EMG) 和姿势分析来测量三个选定肌肉群（股四头肌、腿筋和臀大肌）的激活情况以及七名舞者的骨盆姿势研究。根据训练水平，肌电图描记表明舞者股四头肌或臀大肌的激活程度较高。在所有舞者中，腿筋仍然是最不活跃的肌肉。因此，由于激活水平的差异，婆罗多舞者可能会出现肌肉失衡。此外，骨盆前倾是最常见的错位。运动生物力学、错误的运动适应、骨盆方向主要影响肌肉激活模式。舞者的训练水平和补偿策略会影响表演阿莱曼迪动作时的骨盆姿势。尽管肌肉不平衡和骨盆排列相互影响，但骨盆的方向显着影响腿部肌肉的激活模式。因此，该研究建立了肌肉不平衡和骨盆排列之间的关系。此外，还讨论了这些发现在舞蹈训练中的应用。骨盆的方向显着影响腿部肌肉的激活模式。因此，该研究建立了肌肉不平衡和骨盆排列之间的关系。此外，还讨论了这些发现在舞蹈训练中的应用。骨盆的方向显着影响腿部肌肉的激活模式。因此，该研究建立了肌肉不平衡和骨盆排列之间的关系。此外，还讨论了这些发现在舞蹈训练中的应用。
