Role of Support Receptor Stimulation in Locomotor Training for the Prevention of Hypogravitational Disorders

The time of stimulation of support receptors in locomotor training was analyzed individually for 13 cosmonauts for each day of a long-term space flight. The time of support receptors stimulation with an intensity comparable to that under 1g conditions was shorter compared to Earth conditions. Negative correlation was found between average daily time of support stimulation and the magnitude of changes in the post-flight electromyographic response of soleus muscle to walking. It is proposed to consider the time of support receptors stimulation, along with such parameters as the axial loading and the proportion of the manual mode of treadmill belt movement, as a significant indicator for a personalized approach to the prevention of hypogravitational disorders during long-term space flights.
