[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.

[Effect of immersion hypokinesia on the characteristics of programmed-type voluntary movements].
The effect of immersion hypokinesia on the precision of programme-type voluntary movements was investigated using standard test movements and quantitative analytical methods. The exposure did not cause disorders in the programme mechanisms but reduced significantly the precision range of the motor control system. The loss of precision was at its maximum (by 100% and over) on immersion day 3. The universality and consistency of the above changes indicated their close association with the specific exposure while the fast rate of their development suggested their reflex nature.
