A Comparative Analysis Of The Surface EMG Activity Characteristics Of Professional And Amateur Male Golfers During Their Full Swing

The whole swing of golf is the most basic and important part of golf.At present,there are few literatures on the study of golf electromyography and the study of golf total swing by surface electromyography,and the comparative analysis of the characteristics of professional and amateur golfers’ surface electromyography is rare.This paper takes this as the starting point to seek the difference between professional and amateur golfers’ full swing surface EMG activity characteristics,and provides theoretical basis for golf teaching and training.For professional golfer and amateur golfer(6 each),the golf full swing motion test was carried out by using high speed camera combined with Noraxon surface electromyography acquisition and analysis system.collected the above raw data,using statistical data analysis software SPSS23.0 analysis of professional and amateur golfers full swing muscle integral muscle electrical value,muscle root mean square value,muscle activation time,muscle inactivation time and so on.By using high-speed camera,Noraxon surface electromyography acquisition and analysis system was used to test the total swing movements of professional golfer and amateur golfer(6 each)using No.1 wood and No.7 iron,and to collect the original data of each muscle activity.Based on the statistical data analysis software SPSS23.0 this study compared and analyzed the data of occupational and amateur golfer total swing muscle integral muscle electrical value,muscle root mean square value,muscle activation time,muscle inactivation time and so on.Based on the analysis of the activity characteristics of muscle integral electromyography(iEMG)in different stages of total swing between professional golfer and amateur golfer,it is found that the left triceps of professional golfer is obviously discharged,while the right biceps of amateur golfer is obviously discharged at this stage,and the difference between them is great in the left triceps.Lower pole stage: the overall muscle activity degree of professional and amateur golfer is higher,and the discharge level of each muscle of professional golfer is more balanced,and the muscle discharge level of amateur golfer fluctuates greatly,especially the discharge level difference between bilateral muscles of the same name The opposite sex is obvious.in the stage of full swing with swing: the overall discharge level of the muscles of the amateur golfer is higher than that of the professional golfer,but the discharge level of the left ventral oblique muscle and the right triceps is higher than that of the amateur golfer.The high overall discharge level of the whole swing muscle may be one of the main reasons for the golfers’ back pain,short batting distance and poor batting stability.2.contrast between professional and amateur golfer full swing muscle integral electromyography(iEMG)activity characteristics found that professional golfer left triceps,right pectoralis major muscle discharge trend gradually increased,while amateur golfer muscle discharge trend showed a slow decline.Both professional golfer and amateur golfer take place after hitting the ball at the moment of maximum muscle force in full swing.The most important muscle involved in the total swing of golf.3.professional and amateur golfer’s muscle root mean square(RMS)is obvious.Amateur golfers generally focus on the right side of the muscle force,while ignoring the bilateral muscle balance to ensure the stability of the batting,professional golfers on both sides of the same name muscle force is relatively balanced.The results of this experiment show that we should pay attention to the difference of force characteristics caused by the type of club when carrying out the full swing action training,distinguish the No.7 iron from the No.1 wood practice,and develop the technical action in a balanced way.4.the comparison between professional and amateur golfer full swing action muscle discharge time series analysis found that professional golfer is generally left muscle first,and amateur golfer generally first right side test muscle and then left side force.Professional golfer muscles have more regular timing in each stage of full swing action: the upper stage drives the trunk with the left arm,the lower stage drives the trunk transfer arm with the lower limb muscle timing characteristics;in contrast,the coordination between the full swing movement muscles of the business golfer is not very clear,there is a serious phenomenon of muscle strength disconnection.
