Inertial Movement Analysis Of Chinese Elite Badminton Players

urposes: this study aims to outstanding Chinese badminton players the game running distance,speed and acceleration and deceleration of different intensity and change to the activity measurement and analysis,to explore the running characteristics and rule of badminton sport game,for our country outstanding badminton athletes training and special technology to provide reference data and theory.Methods: nanjing high level sports teams and sports college badminton training in nanjing's national badminton team 12 athletes participated in the test,including six male athletes,female athletes six(age was 18.5±2.4,man is 185.3 ± 2.8 cm,77.2 +±13.8 kg weight,women's height is 168.6 ± 3.5 cm,54.9 ±5.3 kg weight,training duration of 10.6± 2.6,and movement of grade level above)12 athletes is commonly used in the trials with clapping are right,the recent no injuries.In the six competitions conducted in the experiment,the acceleration data of the athletes were collected using the telemetry sensor equipment catapult S5(Optimeye S5,catapult Sports,Australia,100Hz),and the acceleration,deceleration and directional data of the athletes were extracted,collated and analyzed through the associated catapult openfield(catapult openfield,catapult Sports,Australia)system.The hdr-sr12 e,Sony,Japan were used to shoot the field from the air with an elevating platform.The game was recorded to analyze video.The running distance,speed and forehand stroke rate were edited and processed through Simiscout(version2.0,Simirealitymotion,Germany)technical and tactical analysis system.SPSS Statistics 17.0 software was used to analyze and compare the data,and the significant difference was set at P<0.05Results: the running distance of Chinese elite badminton athletes was 977.9±250.3m,the average running time was 23.1 ± 6.5min,and the average running speed was 1.6m/s.Low-intensity and medium-intensity activities accounted for 60.3% and 24.6% of the total activities,respectively,while high-intensity activities accounted for 15.1%.The average number of accelerated runs per race is 52.7 times and deceleration is 53.3 times,among which the accelerated runs are mainly medium and low,accounting for 75% of the total number,with the medium intensity accounting for 19%,and the high intensity accelerating accounting for 6% of the acceleration activities,while in the deceleration activities,the medium intensity activity accounts for 25% and the high intensity deceleration brake is 10%.Studies show that athletes 144.7 times per flat every turn to the left,in turn to the left,the low intensity change to an activity,45% moderate intensity change at 30% to an activity,high strength change at 25% to an activity,to the right to change to the activities of 77.3 times,including the low intensity change to an activity,76% moderate intensity change at 19% to an activity,high strength change to an activity,5% from getting to the point of view,high strength and accelerate activities are mainly concentrated in turn to the left,and in turn to the right,The acceleration times of moderate strength to the right and high strength to the right of male athletes were significantly higher than those of the winning athletes(P < 0.05),and the acceleration times of moderate strength to the right of female athletes were significantly higher than those of the winning athletes(P < 0.05).conclusions and Suggestions: Chinese elite badminton players showed running characteristics of high left-accelerating intensity,mainly repeated short-distance acceleration and deceleration braking,and the ratio of high-intensity deceleration activity was higher than that of high-intensity acceleration.Suggest the badminton coaches and scientific researchers pay attention to development of our country athletes in a short time,repeat acceleration and deceleration braking ability over short distances,and in the physical training,should be more attention to the development of athletes deceleration braking ability,accelerate muscle group ascension work ability at the same time,should also be synchronous improve slow muscle power capability.In the special technical training,athletes who are right-handed should pay attention to the development of the athletes' ability to change to the left,especially the development of the high-intensity acceleration to the left,so as to meet the need of the frequent and high-intensity backhand side movement and hitting.
