Competitive Taijiquan322b+3 Landing Phase The Leg Muscle Force Characteristics Research

With the development of competitive taijiquan modernization and scientific sports training and competition needs,constantly improve the rules of this article to competitive taijiquan 322 b + 3 stages of landing legs muscle force characteristic as the research object, using the DELSYS company Trignotm Wireless System electrical instrument for testing,the main stage, the landing of the technical movements of each link of six legs muscle activation sequence and duration of force and integral electrical values on three aspects to carry on the analysis, and using the principle of sports anatomy and biomechanics combined competitive taijiquan 322 b + 3 action techniques for comprehensive explanation the action of the inherent law and mechanism of leg muscle strength, to improve the technical movement of the landing stability, for the landing stability of competitive taijiquan to skip class difficulty movement of specific training has very important significance.Through the analysis to the following conclusion:1.According to the analysis of action completion time of eight subjects athletes landing stage required schedule shows,the higher the level of the longer the time needed for athletes.Every takeoff stage of athletes, the empty stage, time needed for landing stage show, landing stage time far longer than the time required for takeoff and empty stage.2.Stage of the landing site links, the test of six muscles are activated at the same time, the right gastrocnemius laterally, right long peroneal muscle, right rectus muscle and the duration of the biceps femoris muscle in his right than the right and right the tibialis anterior muscle tendon muscle lasts long; Integral of long peroneal muscle electromyography right value and contribution rate significantly greater than the other five integral myoelectricity value and contribution ratio of the muscles.3.Landing phase of the cushion low link, the tested six muscles are activated at the same time, the long peroneal muscle tibialis anterior muscle of right, right, right, shares the duration of the rectus muscle than right gastrocnemius laterally, right tendon muscle, the duration of the biceps femoris muscle in his right long; Right, right long peroneal muscle, the tibialis anterior muscle strands of rectus muscle and gastrocnemius laterally from right is bigger than the integral myoelectricity value and contribution of the bicepsfemoris muscle in his right, the right muscle tendons of integral value and contribution.4.Landing phase step independent point link, the tested six muscles except gastrocnemius laterally right is activated, the other five muscles are activated at the same time, the right of long peroneal muscle longest; The tibialis anterior muscle right and the right points of long peroneal muscle electromyography value and contribution rate significantly greater than the other four muscles integral myoelectricity value and contribution of the right of the gastrocnemius laterally integral electrical values and the contribution rate to zero.5.Landing phase of the link, the test of six muscles are activated at the same time; Right of gastrocnemius laterally obviously shorter than the duration of the other five muscles;Right leg, right long peroneal muscle and thighs the tibialis anterior muscle strands of rectus muscle of right value and contribution rate significantly greater than the other three muscles of integral myoelectricity value and contribution.Suggestions:1.In the training of competitive taijiquan 322 b + 3 thisdifficulty, the coaches should take scientific and effective training methods to extend the landing buffer time of athletes.2.In competitive taijiquan 322 b + 3 phase of the landing site links, should strengthen the training of the lower leg right long peroneal muscle.3.In competitive taijiquan 322 b + 3 stages of landing buffer low link, should strengthen the right leg, right long peroneal muscle, the tibialis anterior muscle strands of rectus muscle and gastrocnemius laterally from right this four muscles training.4.In competitive taijiquan 322 b + 3 step independent point link in landing phase, should strengthen the right leg and right of long peroneal muscle training the tibialis anterior muscle.5.In competitive taijiquan 322 b + 3 landing stage in the whole link, should be targeted to strengthen the right leg and right long peroneal muscle and the tibialis anterior muscle strands of rectus muscle training right thigh.
