Research On The Monitoring Effect Of TMG Technology In Sports Fatigue

Purposes: At present,the developed countries have achieved good results in the evaluation of muscle sports fatigue and sports injuries of excellent athletes by using TMG(Tensiomyography)technology.TMG technology has been widely used in the field of competitive sports with its non-invasive,convenient,quick and accurate evaluation methods.In C hina,the application of TMG technology has just risen.At present,there has not been the establishment of the corresponding evaluation index system for muscle movement fatigue of excellent athletes in different sports events.The evaluation of athletes' training fatigue depends on the monitoring of physiological and biochemical indexes.Therefore,this paper uses TMG technology to measure the target muscle state of the green team athletes in different training cycles under different training cycles,and determine the physiological and biochemical fatigue indexes under the load intensity.The two people are analyzed and compared,and the physiological and biochemical parameters of the muscle fatigue monitoring under different sports loads are discussed.The correlation between the index and the index index of TMG technology fatigue monitoring,so as to provide theoretical support and practical experience for the rational monitor ing of the sports load of C hinese race walkers and the prevention and damage of sports fatigue by using TMG technology.Methods:In this paper,6 male elite athletes of the race green team(West body group)were taken as the research object,with the rectus femoris,the abdominal oblique muscle and the gastrocnemius muscle as the target muscles.First,the Dm and Tc optimal values of the athletes were established,and the Dm value and the Tc value of the test muscle state of the target players under different cycle training were tracked and monitored.To prevent the injury of muscle fatigue,the fatigue of athletes was monitored by the routine fatigue index serum CK,hemoglobin concentration,red blood cell concentration,urea nitrogen and so on.By analyzing and comparing the changes of Dm,Tc values and physiological and biochemical indexes under different periodic exercise loads and their correlation,the TMG technical indexes were discussed in the movement.The significance of muscle fatigue monitoring is explored,and the application of TMG technology in muscle fatigue monitoring is explored.Results:(1)Muscle Dm and Tc varied with different training intensity.The Dm index decreased with the increase of training load intensity,while the Tc index increased with the increase of training load intensity.In the tenth week,the exercise load reached the maximum.The data of the external oblique muscle,the rectus femoris and the sural muscle accounted for 74%,78%,43% of the optimal Dm value of the target muscles,and the measured Tc values accounted for 132.68%,114.67% and 135% of the optimal Tc value of the muscles,respectively.(2)The increase of training volume,the increase of training intensity to the body stimulation,the athletes morning pulse will appear temporary increase,after the exercise adaptation,the morning pulse will slowly restore and smooth.(3)The hemoglobin content and the number of red blood cells will generally decrease with the increase of external load intensity.(4)There was a very significant negative correlation between serum CK and Dm,and a very significant positive correlation with Tc(p=0.01,|r| > 0.8);the number of red cells was positively correlated with Dm,and had a significant negative correlation with Tc(p=0.01,|r| > 0.8);BUN was not very significant with Dm and Tc.Correlation(p=0.01,|r|<0.8).Conclusions:(1)The main monitoring muscle status and physiological and biochemical indexes of the Guoqing walking team(West body group)in different training periods are different: the average exercise load is 75.53 in the preparation stage,the average load intensity of the mixed oxygen stage is 89.77,and the average load intensity of the pre competition adjustment stage is 46.05.Its goal is to monitor muscle state without excessive fatigue and cause sports injuries.The number of RBC and the concentration of Hb were in the normal range in the different cycles,and there was no phenomenon of low index.The content of CK and the concentration of BUN were generally higher than the normal range of the index evaluation.(2)The Dm value and Tc value of muscle state vary with the training intensity.The Dm value decreases with the increase of training load,and the Tc value increases with the increase of training intensity.TMG technology can be used to monitor the fatigue state of target muscles.(3)The correlation between the Dm value and the Tc value of the muscle state and the serum CK and the concentration of red blood cells was significant.The serum CK and Dm were significantly negatively correlated with the Tc,and the number of red cells was positively correlated with Dm,and was negatively correlated with Tc;BUN was not significantly related to Dm and Tc.There is no significant correlation between C.TMG techno logy can be used for monitoring of peripheral fatigue.(4)TMG technology is simple,convenient and portable,and can be tested at any time.It can be widely used as a new method of training monitoring.
