Kinematics Study On The Influence Of Different Load Resistance Parachute On The Running Technique Of Sprint

With the continuous innovation of the sprint training concept and the scientific development of training methods,the world sprint performance has been continuously improved.The competition of sprint sports has gradually evolved into a high level and scientific training process,which puts higher requirements on the scientific degree of training.Resistance training has always been an important means of sprint training.In recent years,resistance umbrellas have been used more and more in sprint training.In the process of resistance parachute training,both resistance and athlete skills must be taken into account.Three kinds of resistance parachute running with different loads were set up.The changes of the joint angles of the athletes' body when testing three different load resistance umbrellas were compared with the changes of the angles of the joints of the athletes during the horizontal running,and the related kinematics were discussed.The characteristics of the index change,so as to find the resistance of properly resistance training and special strength training in three different loads,further reveal the essential characteristics of the resistance training in the resistance parachute running mode.This paper studies the influence of different resistance parachute on sprint technique through literature method,interview method,experimental method,video analysis method and mathematical statistics.The following conclusions are drawn through research:1.There is no significant impact on the athletes' running time and support time.The medium-load resistance umbrella and the large-load resistance umbrella have significant influence on the athletes' running time and support time,which can be used for special strength training.2.On the way of the athletes running the lower limb buffer stage,the small load resistance umbrella has no significant effect on the athlete's torso anteversion angle,hip angle,knee angle,squat foot,front support distance and calf angle;medium load resistance umbrella,large load resistance umbrella to the above indicators Has a significant impact.When the small load resistance parachute runs,the standard technical action is guaranteed.The medium load resistance umbrella and the large load resistance umbrella affect the performance of the athlete's identification technology.3.After the athletes ran on the way,the small load resistance umbrella and the medium load resistance umbrella did not change significantly on the hip and knee angle.The large load resistance umbrella changed the angle of each joint,indicating that under the heavy load resistance umbrella,the athlete could not After completing the full squatting,it is a good special strength training method to improve the athlete's heel effect.4.During the sprinting stage of the athletes,the middle load resistance umbrella and the large load resistance umbrella have obvious changes on the hip angle and the knee angle.The difference between the movement technique and the non-umbrella movement is significant,so the medium load resistance umbrella and the large load resistance umbrella are suitable for Special strength training to improve the athlete's ability to swing forward.There is no significant difference between the small load resistance umbrella and the non-umbrella running joint angle,and there is no obvious change in the motion technique.It is suitable for special technical training to improve the swinging front swing technique in the middle of the running.5.The small load resistance umbrella has no significant influence on the athlete's running technique when generating resistance,so it can be used to stabilize and improve the running technique.The medium-duty drag umbrella and the heavy-duty drag umbrella have a significant impact on the athlete's running skills,so they can be used as special strength training during the running.
