The article describes current knowledge about the kinematics of the human body falling from a height in the case of active jump, thrust or spontaneous fall. Available literature data and results from own experimental and expert practice are presented. The aim of the treatise is to determine the maximum values of jump or fall. Literary values are analysed and results of experiments are presented. The results were obtained by measuring volunteers dropping, helper dropping into water pool. There are several important factors to consider when biomechanically assessing a fall from a height. These are the individual's training, gender and also the psychic component, the inner decision whether the individual consciously jumps with maximum effort, or is a sudden fall or just an average jump.
