Research On The Effect Of Functional Training On The Sensitivity Of Sanda Athletes Leg Method

Sanda is an antagonistic sport of fighting in the same field,and it is an important part of Chinese martial arts.With the fierce development of Sanda competition,higher requirements are put forward for athletes in all aspects of competitive ability.As an important part of the Sanda technique,the whip kick is a key scoring method for athletes and directly affects their competition results.Through video analysis of college students’ Sanda competitions in recent years,it is found that the use rate of whip leg is higher than other techniques,but the hit rate and scoring rate are lower,and the success rate of this action is closely related to the agility of athletes.Relevant studies have shown that functional training can effectively develop the agility of athletes.The training can make the body in an unstable state for training,which is gainful to improving the explosive power of the lower limbs,the stability of the single leg,the agility of footsteps,the stability of the trunk and the core,and the strengthening of muscles.The ability to coordinate and cooperate with each other,thereby improving the agility of athletes’ movements and techniques.The research adopts methods such as literature,video observation,expert interviews,questionnaire surveys,mathematical statistics,and experiments.It takes the impact of functional training on the sensitivity of Sanda athletes’ whip leg as the research object,and takes the functional training mechanism as the logical starting point.The influencing factor of leg sensitivity is the problem domain.14 male athletes were randomly selected from the Sanda class of the Physical Education College of Hunan Normal University as experimental subjects for 12 weeks of intervention training.The experiment selected whip leg action lower limb muscle surface electromyography,whip leg reaction time,20 s high,middle and low combined whip leg,and 20 s multi-directional whip leg as test indicators.The data of the two groups of athletes before and after the experiment were statistically analyzed.The study concluded that:(1)After 12 weeks of experimental intervention,the statistical analysis of the data of the two groups of athletes before and after the experiment found that the functional training group and the traditional agility training group have different degrees of improvement compared with before the experiment.Both methods can enhance the college students’ Sanda Athlete’s whip leg sensitivity.The increase in the number and growth rate of the two groups of experimental subjects showed that the whip leg sensitivity of the experimental group was significantly improved.Because of the control group,it is believed that functional training is more effective than traditional sensitive training.(2)In terms of sensitivity.After the experiment,the whip leg reaction VII time of the control group increased by 7.143(ms)compared with that before the experiment,and there was no significant difference.The experimental group increased by 16.429(ms),which is a significant difference.Therefore,functional training can effectively improve the athlete’s ability to process specific signals,speed up visual search,develop the brain’s cortical nerve mobility,and increase its responsiveness.(3)In terms of the ability to quickly change movements.After the experiment,the test group and the blank group increased by 7.041% and2.847% respectively in the 20 s high,middle and low combined whip leg test.There is a very major difference between the test group and the Blank group.After the experiment,the two groups of athletes have significant differences in the 20 s combination of high,middle and low whip leg performance.It is believed that functional training is better than traditional agility training in improving the athlete’s acceleration start and deceleration braking effect,thereby increasing their ability to quickly change movements.(4)In terms of the ability to quickly change direction.After the experiment,the test group and the blank group increased by 13.044% and3.249% respectively in the 20 s multi-directional whip leg test.There are big major differences between the test group and the command group.After the experiment,there are significant differences in the 20 s multi-directional whip leg performance of the two groups of athletes.Therefore,it is believed that functional training can enhance the explosive power of the lower limbs and physical coordination of the Sanda athletes,thereby optimizing their ability to quickly change directions.(5)In terms of surface electromyography.In the integrated EMG indicators,the functional training group after the experiment has very significant differences in the rectus femoris,biceps femoris,gastrocnemius and tensor fasciae muscles at the T1 stage compared with the traditional sensitive training group;the rectus femoris at the T2 stage There are very significant differences in muscles,gastrocnemius,tensor fascia lata,and biceps femoris;there are significant differences in the rectus femoris,gastrocnemius,lateral femoris,and gluteus maximus in the T3 stage,and the tibia anterior There are significant differences in muscle.In the index of muscle contribution rate,before the experiment,the muscle contribution rate of the two groups of athletes’ whip-leg movements was roughly the same,and there was no significant change.After the experiment,the biceps femoris,rectus femoris,and lateral femoris in the functional training group had a greater contribution rate and more stable muscles than the traditional sensitive training group.Therefore,functional training can significantly enhance the muscle strength of the lower limbs of Sanda athletes,optimize the structure of the whip leg movement,and improve their agility.
