Maintaining The Electromyography Analysis Of High Quality Tango Dance Holds

In this study,the methods of literature,experiment and mathematical analysis were used to analyze the high-quality hold EMG of tango dance.The subjects were10 men and 10 women,20 in total.The experimental instrument was Delsys trigno wireless EMG system wireless surface EMG tester produced in the United States,which was matched with Quali Sys Red Camera to ensure the synchronization of EMG and movement.The frequency of use in tango dance was selected for the test action The highest closed position,side row position and side row position are the two movements composed of three body positions: forward and step to side row,and back to left sliding axis;20 subjects are divided into excellent group and good group by expert video scoring,and the left and right deltoid,trapezoid and back muscles between excellent group and good group are found by analyzing the integral EMG value,contribution rate and linear envelope of the two groups The difference of latissimus muscle in tango dance.The results showed that the left and right deltoids of all subjects were the ones that did the most work in the two movements of moving forward with walking to the side and moving back to the left sliding axis Men In the good group used Latissimus Dorsi muscle more than those in the good group,and the muscle power of the good group was stable,so the grip will be deformed.The right Latissimus Dorsi muscle was used more by the women in both the forward and sideways movements;the good women used more of the left slide axis in the backward motion than the good women,the muscles are more stable and use more of the right Latissimus Dorsi.There were no significant differences in muscle strength,muscle work participation and muscle stability between the two groups.The results of t-test showed that there was no significant difference between the two groups in the value and contribution rate of integral emg between the two groups.The contribution rate of the right Latissimus Dorsi and the right Trapezius muscle in the good group was significantly different(p < 0.01),there was a significant difference in iemg between left deltoid and right Latissimus Dorsi during the first stage of the movement(p <0.01),there were significant differences in the IEMG values of the left Latissimus Dorsi(p < 0.01),the contribution rate of the right Latissimus Dorsi(p < 0.01),there were significant differences in left Latissimus DORSI INTEGRAL EMG values(p <0.05),and the contribution rates of left deltoid and left Latissimus Dorsi were significantly different(p < 0.01),there was significant difference in the contribution rate of right Latissimus Dorsi in men(p < 0.05).There was significant difference in the second stage of left Latissimus Dorsi between the two groups(p < 0.05),in the second stage,there was a significant difference in iemg between the right Trapezius and the left Latissimus Dorsi(p < 0.01).To sum up,the use of Latissimus Dorsi muscle can provide good stability for holding,and in the case of cooperation,the quality of men’s holding has a greater impact on the holding of two people.
