Biomechanical Analysis Of The Effect Of Spike Rotation System In Tibia Area

Objective: The non-contact injury in football is a relatively common type of injury.In the process of how to reduce the frequency of non-contact injuries in football from the perspective of sports biomechanics,a new type of large-bottom structure was invented creatively.The observation of the shooting action changes the structure and arrangement of spikes in the metatarsal area of the football shoe to release the torsional moment of the knee joint.This study compares the shape and arrangement of spikes in the metatarsal area of the forefoot by comparing the technical movements in the football movement.Scientific simulations help the lower limbs to increase the rotational amplitude of the supporting legs in the course of support in changing the direction of movement and kicking the ball.The function of the knee valgus torque is designed to support the biomechanical parameters of the leg during the artificial turf(AT)shooting process in the forefoot metatarsal pedicle stud rotation system and the general soccer shoe.The construction of studs and general studs have the effect of reducing the impact of non-contact sports injuries during shooting by football players supporting the legs.Methods: In the experiment,12 adult male football players were selected as subjects.The staff asked the participants to wear A-spinal design(AT)and A-spiral design(AS).A fixed shot(FS)is performed in the artificial grass under the laboratory,and the acceleration distance is one step.The experimental equipment includes Vicon infrared three-dimensional motion capture system for collecting the lower extremity kinematics data of the subjects during the exercise;Kastler three-dimensional force table for the simultaneous acquisition of the ground reaction force of the subject's left leg supporting period and other dynamics data.Experimental data were analyzed using statistical analysis software SPSS 17.0 using Oneway Repeated Measures ANOVA and Bonferroni post hoc analysis.Spinning system soccer shoe stud construction and regular soccer shoes against football players' lower limbs.The differences in kinematics and kinetic parameters were set at a significance level of 0.05.Results: In terms of kinematics,the peak value of the lower leg joints and lower joint activities of the supporting legs wearing the spin screw technology soccer shoes is significantly smaller than that of the ordinary soccer shoes;in terms of dynamics,the peak ground reaction force of the soccer shoes wearing the screwing system is vertical.There was no significant difference between the resultant force and wearing the ordinary football shoes,but the vertical reaction load rate(VALR)of the ground reaction force when wearing the tacking system soccer shoes was significantly lower than that of the ordinary soccer shoes,P=0.017;The peak ground reaction force(PHF)is not significantly different from that of ordinary soccer shoes,but the horizontal reaction loading rate(VALR)of the floor reaction force when wearing the screwing system is significantly lower than that of the ordinary soccer shoes,P=0.027;In terms of joint torque,the peak torque of the lower extremity joints of the supporting legs wearing the spin screw technology soccer shoes is significantly smaller than that of the ordinary soccer shoes.The experimental results are the same as expected,and the tarsal region screwing system can significantly reduce the torsional moment of the lower limb joint during shooting and reduce the non-contact damage caused during the exercise.Conclusions and Implications: In the shooting action of the athlete,the inertia of the supporting leg due to the swing of the body during the shooting increases the load on the joint.In the shooting process,the larger flexion angle and flexion activity can better buffer the reaction force from the ground when landing,while the metatarsal area screwing system can reduce the knee abduction angle and better reduce the lock between the shoe and the ground.Mechanisms to increase the angle of external rotation of the ankle joint,release torque,reduce knee joint pressure,and reduce the risk of anterior cruciate ligament(ACL)injury.Ordinary football shoes have a large vertical loading rate(VALR)of ground reaction force.Excessively high VALR may lead to increased risk of soft tissue injury of lower extremity joints such as gingivitis.Experiments have shown that the biomechanical effects of shank region screwing technology on the lower extremities are significant.Effective.It is suggested that from a practical point of view,we should better understand the needs of sports.We should boldly innovate on this basis,combine theory with practice,and provide reference for new research directions.
