[Modeling of human movements under conditions of varying gravitational force].

The control of man's movements during adaptation to an altered gravity field was modelled by mathematical methods. Two types of movements were investigated: forearm displacements with various loads and repulsions from a support in zero-g and at high g's. It has been shown that movement coordination in altered gravity fields can be maintained due to a rearrangement of the control over muscle contraction which includes changes in the amplitude and pattern of joint momenta in harmony with the gravity changes.
