Background and Study Aim. The aim of present study was verification of rotating training simulator (RTS) as an assessment tool of susceptibility of  the body injuries during the fall caused by an external force.
Material and Methods. A Group of 68 students of physical education from University of Zielona Góra were tested. Appropriateness was determined by comparing results of RTS?s test for different frequencies (from 0,16 Hz to 0,3 HZ) with results of I task from STBDIF test designed by Roman Maciej Kalina, adopting the same criteria and grading scale. Reliability of RTS?s test results was evaluated by retesting subjects after one week, and also comparing grades given by two observers with those given by authors.
Results. Current results show significant correlation between STBDIF test and RTS?s test for each frequency. There are very high correlations  between first test and retest after one week results of RTS?s test. For 31 subjects obtained results show good and excellent reliability defined by intraclass correlation coefficient (ICC).
Conclusions. Obtained results show that rotating training simulator is a valid and reliable tool to diagnose susceptibility of the body injuries during the fall caused by an external force and exhibits significant repeatability of results.
Key words: simulating falls ? safe fall ? motor safety? biomechanics? rotational movements
