We present results from a comparative analysis of the biomechanical characteristics of human gait before and after prolonged antiorthostatic hypokinesia with a body slope angle of –6° relative to the horizontal as a model of microgravitation (the ANOH group) and orthostatic hypokinesia with a positive body angle of +9.6° relative to the horizontal as model of lunar gravitation (the MOON group). Biomechanical gait characteristics were analyzed at a rate of 60 steps/min on a treadmill. Leg joint angles were measured at the hip, knee, and ankle. The electromyographic characteristics of the knee and hip muscles were also recorded. The study results showed that the most marked influences on human gait parameters were seen in subjects of the ANOH group, which was reflected in changes in the leg joint angles at different phases of stepping and changes in the electrical activity of muscles. Subjects of the MOON group showed analogous but less marked changes.
