Variability of locomotor strategy of cosmonauts at different stages of long-term space flight

The paper investigates the possibility of using biometric data obtained with the help of a pressure sensor on the support when a person moves on it to obtain conclusions about the state or change of its locomotive functions over time. Three types of indicators are constructed. The first type of indicators shows the level of error of the integral characteristics of the sensor readings. The second type refers to the assessment of changes in the time form of the pressure pulse in one step during training. The third type is the index of unsteadiness of the time series of deviations, showing the differences in the adaptive capabilities of the organism in different modes of movement.
