摘要：Background and Study Aim: Power and neural response are two fundamental elements in many martial arts striking. Currently, there are no practical methods exist to present these aspects to coaches and athletes in a training environment. This study introduced a new method for quantifying the two factors that could be used in real-time biofeedback training. Material and Methods: The new method consisted of self-developed optical signal system, EMG measurement and 3D motion capture. The quantification was done by using kinematics of the punching bag and striking limbs analyzed with self-developed dynamic calculation programs. The setup was very close to a training environment with neglect-able influence on an athlete performance. Results: The results showed that such quantification provided both total power and power components (i.e. linear & angular) of striking as well as the related response processes/time. Conclusions: Since the method could offer feedback of power intensity, attack accuracy, central and peripheral reaction time to coachers and athletes, it would have great potential to become a biofeedback tool in practice for increasing training efficiency and effectiveness
