Abstract
The data is the kinematic data obtained from the analysis of "324C+1D", a difficult Wushu movement completed by the first-level athletes of Chinese competitive Wushu routine, by using SIMI sports software. It is mainly used to study the kinematic characteristics of the difficult Wushu movement "324C+1D".

The data I submitted is all the human joint movement data of the whole movement process obtained by using SIMI motion software to analyze the martial arts difficult movement "324C+1D" completed by first-level martial arts athletes.
Description of data and file structures
The files named "SIMI data - Athlete A", "SIMI data - Athlete B" and "SIMI data - Athlete C" contain the body shutdown movement data of 3 first Level wushu athletes from the start of the run-up to the completion of the entire movements "324C+1D".
The files named: "The left and right knee sector Angle data of athlete A", "The left and right knee sector Angle data of athlete B", "The left and right knee sector Angle data of athlete C" are supplementary data about the changes in the knee sector Angle of 3 wushu first-level athletes in completing the martial arts difficult movements "324C+1D".
The files named "Athlete A", "Athlete B" and "Athlete C" are supplementary data about the change of the angular speed of the shoulder axis rotation of 3 first-level Wushu athletes in completing the Wushu difficulty movements "324C+1D".
Description of the picture file:
Figure 1 is the characteristic action diagram of the action process of "324C+1D".
Supporting forms:Supporting forms contains all of the data tables I use in the article.
Relevant definitions in this study:
Hip Angle: refers to the Angle between the line from the acromion to the center of the hip joint and the line from the center of the hip joint to the center of the knee joint.
Knee Angle: refers to the Angle formed by the center of the ipsilateral hip joint, the line to the center of the knee joint, and the line from the center of the knee joint to the center of the bare joint.
Ankle Angle: refers to the Angle formed by the line from the center of the ipsilateral knee joint to the center of the ankle joint and the line from the heel to the toe.
Center of gravity lifting Angle: refers to the Angle between center of gravity velocity and horizontal plane at the moment of lifting off the ground.
Torsional Angle of shoulder and hip: It refers to the Angle formed by the projection of the two acromial lines and the two central lines of hip joints on the horizontal plane. The index of shoulder-hip torsional Angle selected in this study is: the peak value of shoulder-hip torsional Angle at the take-off stage of the difficult movement "324C+1D" .
Shoulder and foot torsion Angle: Refers to the Angle formed by the projection of the two acromial lines and the two treading joint center lines on the horizontal plane.
Rotational angular velocity of the acromion: refers to the projection of two acromion lines on the horizontal plane and the rotational Angle within unit time (s). This index mainly reflects the rotational angular velocity of the trunk around the vertical axis. The indexes of rotational angular velocity of the shoulder shaft selected in this study are: rotational angular velocity of the shoulder shaft at the moment of striking in the air stage of the difficult movement "324C+1D", peak rotational angular velocity of the shoulder shaft after striking and rotational angular velocity of the shoulder shaft at the moment of landing.
Swing arm speed: In this study, the motion speed of the wrist joint was used to represent the swing arm speed. Selected swing arm speed measure is: the difficult movement "324C+1D" peak action in the take-off phase of the swing arm speed.
Swing leg speed: In this study, the motion speed of the pointe point represents the swing leg speed. The selected index of leg swing speed is: the right leg swing speed in the air stage of the difficult movement "324C+1D".
Joint sector Angle: is the range of Angle change of the knuckle. The index of joint fan Angle selected in this study is: the knee fan Angle in the landing stage of difficult movement "324C+1D".
Horizontal movement distance of the center of gravity: Refers to the movement distance of the center of gravity of the human body on the horizontal plane. The horizontal moving distance of the center of gravity selected in this study is as follows: the horizontal moving distance of the center of gravity in the airborne stage of the difficult movement "324C+1D".
Vertical movement distance: Refers to the movement distance of the center of gravity of the human body on the vertical axis. The vertical movement distance index of the center of gravity selected in this study is: the vertical movement distance of the center of gravity in the take-off stage, the take-off stage and the landing stage of the pendulums in the air. The take-off stage includes the lifting distance of the center of gravity and the falling distance of the center of gravity.
Share/access information
The data submitted this time are all the original data obtained by the researchers' testing, which is only provided to this database at present, and there is no other way to obtain it. Relevant researchers are requested to download and use the link provided in this database.
code/software
This data is the data edited by Excel, all in XLSX format data files. Researchers can view all the data using a computer with Microsoft office or open the data using WPS Office software. This data is intended for use only by researchers engaged in sports biomechanics research.
Here is a summary of the changes made (since the previously published version) : renamed the data file to make it easier for readers to understand; translated the Chinese in the data file into English to make it easier for readers to use; deleted Figures 2, 3, 4, 5, 6, 7, 8, and 9 from the original data support file. Since Figure 1 contains all the action processes in the picture, it makes the picture more concise and easy to understand.
Methods
Three Japanese SONY-RX10IV cameras, a set of SIMI Motion software of SIMI company, calibration frame using Agger 3D DTL framework calibration. 3D high-speed camera system can be used in the study of human movement, which can truly reproduce the movement and movement trajectory of athletes, and output the movement data of each link of athletes at any time, such as displacement, speed, angular speed, etc., so as to facilitate quantitative analysis. Combined with the principles of human physiology and physics, the research and improvement methods can make the observation of human movement get rid of the state of relying purely on experience. Enter the theoretical, digital era. 3D high-speed camera is a non-contact measurement, which has the advantages of not imposing extra load on the human body, not interfering with the body movement and measuring close to the actual condition. The detection and processing of human motion information takes human motion as the research object. Measure and analyze the displacement, velocity, acceleration and joint Angle of each part of the human body in the process of movement. 3D high speed camera system is mainly used to study the kinematic characteristics of motion technology.
SIMI motion analysis software can analyze difficult motion videos captured by high-speed camera systems and convert moving images into motion data. The kinematic characteristics of Wushu difficult movements are analyzed through motion data.
