Electromyographic Analysis of Chest and Back Muscles and their Correlation with the Performance of Jump Tennis Service in Volleyball
Journal Title: Journal of Advances in Sports and Physical Education - Year 2018, Vol 1, Issue 1
Abstract
Abstract:The Purpose of the study was to EMG Analysis of Chest and Back Muscles and their Correlation with the Performance of Jump Tennis Service in Volleyball. Coverage/ Selection of Subjects: Universe of the Study: The study was confined to India only. Sampling Frame: Subjects were selected as a sampling frame from India only and their age was ranging from 16 to 28 years. Sampling Methods: Subjects were selected on the basis of purposively random sampling method. Sampling Size: A total of 12 male professional Volleyball players from India were selected for the study. Units of Observation: Observations were made on the following Variables/contents: Pectoralis Major (PMJ), & Trapezius (TP). Criterion Measures: Muscles activities during jump tennis service in volleyball were measured by NeuroTracMyo Plus 4. The data was recorded in micro volt (µv). Statistical Techniques: The concerned data was analyzed by using descriptive statistical in order to electromyographic analyses of chest & back muscles during executing the jump tennis service in volleyball. In order to determine the relationship of selected (chest & back) muscles activities with the performance of jump tennis service in volleyball, Pearson Multiple Correlation Technique was used. The level of significance for the entire analysis was set at the 0.05 level. Conclusions: According to finding the study, Trapezius muscle showed the highest activation level of EMG during execution of jump tennis servive in Volleyball. Pectoralis muscles showed the 5th highest activation level of EMG during execution of jump tennis service in Volleyball. Only one muscles group that is Pectoralis is found correlated with the performance of jump tennis service in Volleyball. The insignificant relationship was found between back (Trapezius) muscles and with the performance of jump tennis service in Volleyball. Keywords: Electromyographic Analysis, Chest & Back Muscles & Tennis Service.
