An Analysis of Electromyographical Recordings of Volleyball Players of Varied Playing Ability

The objective of the study was to determine the extent to which certain muscles contracted during the execution of the jump serve skill in volleyball, and the participants were divided into various different playing groups. Methods All participants in this study were right-handed college players. Their ages varied from 19 to 25. Eight high- and low-ability players were also present. Only the Rectus Femoris, Gastrocnemius, Anterior Deltoid, and Triceps Brachii were studied. All EMG methodology and testing protocols were applied in advance to ensure a successful test and data gathering. We used the eight-channel EMG Bio-feedback of Thought device to select muscles for data gathering. Before the test, participants were given a detailed presentation and explanation of its aims. After that, palpation marked and put the electrodes. Everyone then had to perform the job, and microvolts (v) signified muscle contraction. This study hypothesised that volleyball players with different muscle contraction skills would have different jump sets. Both sets of volleyball players performed jump serves, and an independent t-test determined if they contracted their muscles voluntarily. Level of significance was 0.05. Finding only Anterior Deltoid (Right) and Triceps Brachii (Right) revealed significant difference between high and low playing ability groups, as their calculated t values (9.174) and (4.351) were higher than the tabulated value (2.145) at 0.05. Conclusion During jump service execution, high and low volleyball players had substantial variations in anterior deltoid (right) and triceps brachii (right) muscle contraction.
