One of them is the program "Pongae (lightning) 1.0", an integrated reaction check system on motion developed by the Computer Center of Kim Chaek University of Technology.

This system which makes it possible to estimate quickly and correctly ten indices is being introduced in various sports teams.

The system conducts the integrated reaction check on motion with the real-time statistical analysis processing program instead of former conventional measuring method, thus helping coaches select athletes and judge their training in a scientific way.

The estimation method is as follows:

From the moment when athletes put their feet on the reaction check board according to the computer-presented situation, necessary figures are calculated and appear on the screen.

The better the physical preparation is, the more the frequencies of stamping are the shorter the moment of touching the check board is.

By this method, the coaches can judge the physical capability of athletes and find out kinesthesia that cannot be solved through training.

It can estimate the flexibility, motion speed, ability to adopt determination and inheritance.
