Sports Biomechanics
Sports biomechanics refers to the scientific study and quantitative analysis of technical movements of professional athletes. To achieve this, researchers often need to use research equipment such as optical motioncapture,three-dimensional force platforms, and electromyography. The types of data involved in sports biomechanics research include kinematic data, kinetic data, and electromyographic data. Processing and analyzing these data types is fundamental to conducting any biomechanical study. However, organizing this data and calculating the indices of interest is a highly challenging task, primarily due to many researchers' lack of experience with data analysis software.
An athlete is performing a baseball pitch. Infrared reflective markers are attached to their body for three-dimensional reconstruction of the movement.
The video on the left shows the movement of a badminton racket in the X, Y, and Z directions in three-dimensional space during a jump smash, while the video on the right demonstrates the same technical movement but focuses on the right knee's extension/flexion, inversion/eversion, and internal/external rotation angle changes. Through the analysis of kinematic characteristics, one can understand the completion of the technical movement.
Our provides processing and computation of kinematic data and can assist in writing professional analysis reports as needed.
In the field of sports science, kinematics includes joint angles, angular velocity, angular acceleration, displacement of the body's center of mass, and its velocity, among other things. In other words, kinematics describes the motion of points, objects, and systems of objects, without considering the forces that cause them to move. In sports science, kinematic characteristics are often used to evaluate the rationality of external technical movements and provide suggestions for their improvement and optimization.

Kinematic
The video on the left displays the changes in knee joint torque of the right lower limb during a hurdle crossing task, with the torque data normalized using the subject's body weight. The video on the right shows the changes in the ground reaction forces in three directions on a force plate during a baseball player's uppercut swing. By observing the changes in kinetic characteristics, one can understand the features of executing a particular action, which can then provide references for the development and planning of strength training programs.

In the field of sports science, kinetic data includes joint torques, joint reaction forces, joint power, impulse, and more. Kinetic is a branch of classical mechanics which, unlike kinematics, focuses on the relationship between motion and its causes, particularly forces and torque. In sports science, kinematic characteristics are often related to evaluations of strength or endurance levels, as changes in dynamic characteristics are directly produced by muscle contractions. By examining kinetic parameters, one can provide a basis for planning specific or fundamental strength training. Watch the following video to start understanding kinetics:
Kinetic
Electromyography (EMG) data is another crucial aspect in addition to kinematic and kinetic data, and in some respects, EMG results can be even more critical than kinematic or kinetic data. This is because current biomechanical research has gradually shifted from analyzing external kinematic or dynamic indices to focusing on mechanisms. Since EMG data reflects neuromuscular control strategies, its results become vital for researchers. Typical analyses of EMG data include time-domain and frequency-domain analyses, with common indicators being integrated EMG (reflecting the overall recruitment of muscles), root mean square (RMS) amplitude (indicating the frequency of muscle mobilization), normalized linear envelopes (representing the percentage of muscle activation), and zero crossing rates (indicating muscle fatigue levels).
