The user cannot predict the position of the treadmill and the intensity of the interference. Each step is different and the nervous system is constantly forced to process different sensory information and thus, it produces different motor outputs in order to react more quickly and more efficiently to the typical unexpected events of the outdoor running experience.

Training with REAX RUN produces greater efficiency in the locomotion. For the standard population, it is an outstanding tool to improve balance and prevent falls. For athletes it can be considered very useful to reach the maximum efficiency level while training.
