The study was undertaken to investigate the change of cardiac compression force relative to levels of information provision using components of ground reaction force. Male participants of 20s-30s (n=10) who was not trained on cardiopulmonary resuscitation (CPR) and used an automated external defibrillator carried out CPR using manikin on ground reaction force plate. All executed 30 times the CPR according to the levels (1-time viewing, repeated viewing, and basic life support education) of information provision and then total sample of 300 times of ground reaction force data was utilized for the analysis. Rather basic life support condition than 1-time viewing and repeated viewing in velocity of CPR showed better pattern, and executed within 15.09 sec of total elapsed time. Also rather basic life support condition than 1-time viewing and repeated viewing in vertical compression force during release phase showed better relax-ability. Rather basic life support condition than 1-time viewing and repeated viewing in ground reaction force of anterior-posterior direction during contraction phase was insignificant, and reduced compression force toward the oblique direction. Therefore CPR training should be provided as part of cardiac and exercise rehabilitation programs in range of limited scope. It is necessary to include not only definite information but also a practice course of CPR to enhance the survival rate of the cardiac arrested regardless of progressive and scientific growth of CPR fields.
