The kinematic and electromyographic parameters of a normal walking pattern have been studied before immersion and on the sixth day of immersion in six volunteers aged 22-25 years. It has been shown that exposure to supportless conditions for six days resulted in a decrease in the angular velocities in the knee and ankle joints and small changes in the amplitude of angular motions in the joints of the leg. However, the kinematic stereotype of locomotor movements was not significantly changed after six days of immersion. An increase in the electromyographic cost of the shin locomotion indicates shifts in the central and peripheral systems of the locomotion apparatus.
