[Dynamics of cyclic and acyclic locomotion by the crew of "Soyuz-18" after a 63-day space flight].

After the 63-day flight Soyuz-18 crewmembers P. I. Klimuk and V. I. Sevastyanov performed different types of walking, long and high jumps. During the exercises the coordination structure, bioelectric activity of anterior and posterior groups of calf and femoral muscles, distribution of loads along three coordinate axes in the center of body gravity and support reactions of feet were investigated. The study demonstrated certain stages in the recovery processes, duration of the readaptation period, dependence of the level of locomotion disorders upon the inflight exercises. The investigation showed a better condition of the locomotion functions of Soyuz-18 crewmembers as compared with those of Soyuz-9 and Soyuz-17 cosmonauts. The study also helped to determine how to arrange the readaptation period.
