[Biomechanics and movements of the body after 120-day antiorthostatic hypokinesia].

This paper presents data on body parameters (weight and circumference) and walking biomechanics after 120-day head-down tilt. The exposure leads to changes primarily in the anti-gravitational muscles. They are assumed to be caused by relative changes in the fat and muscle components. Head-down tilt also produces changes in the kinematic parameters of the walking process, the shape of support reactions, and losses in the cost-efficiency of the walking process.
