Electromyographical Bilateral Asymmetry of the lower limbs in Volleyball Players
Electromyographical Bilateral Asymmetry of the lower limbs In Volleyball Players Amar Kumar* *Assistant Professor, Lakshmibai National Institute of Physical Education Lower limb actions such as jumping, standing and squatting all require both legs to act equally to provide the most efficient movement, and limit the development of bilateral asymmetries which may lead to unilateral trauma and reduced performance. In this study ten male volleyball players with age ranged from eighteen to twenty four years of Lakshmibai National Institute of Physical Education, Gwalior. By Reviewing the literature and consultation with experts major muscles of lower limb i.e vastus lateralis, vastus medialis, Rectus femoris and gastrocnemius were selected. To investigate the bilateral asymmetries electromyography technique was used to determine the electrical activity during maximum voluntary isometric contraction (MVIC). Pro comp Infiniti of Bio Tec Thought Technology of eight channels was used as instrument to measure electrical activity. After a brief warm-up, electrode placement participants were tested thrice for maximum voluntary isometric contraction within the rest period in between of 3 minute to avoid any Fatigue. Descriptive statistics and t- test were applied to check the bilateral asymmetry at0.05 level of significance. The findings of the study showed a significant difference in bilateral asymmetries of selected muscle group of lower limbs. Vastus lateralis showed highest electrical activity and gastrocnemius right shows lowest electrical activity during MVIC.
