In light of these differences, there is no assurance that vector coding and CRP convey similar information on the structure of variability when they are used to study a particular movement.
com Issue were to directly compare roundhouse kick’s variability quantified by vector coding and CRP in Taekwondo, and to determine if these techniques convey similar information on variability.
In experimental setup, we chose the roundhouse kick being testing movement, which is the most frequently used technique in competitions, the Motion Analysis System with 5 high speed cameras (S Infrared, Vicon camera, Oxford metrics, Oxford, UK) were used to collect the kinematics data (sampling rate at 200 Hz) through tracking the 22 makers automatically, and then the joint velocity and angular velocity for each lower limb were derived from the time series."
