CHANGES IN THE WORK CAPACITY OF HUMAN MUSCLE AFTER EXPOSURE TO HYPOKINETIC CONDITIONS (IZMENENIE MYSHECHNOI RABOTOSPOSOBNOSTI POSLE PREBYVANIYA CHELOVEKA V USLOVIYAKH GIPOKINEZII),
Abstract
The limitation of muscular activity that can occur during spaceflight impairs the functional state of the motor apparatus. The functional shifts in the muscular apparatus during dynamic work are characterized by more rapid fatigue. The quality of dynamic work decreases after man is exposed to limited muscular activity. The decrease is characterized by a decrease in the force of muscular contractions and a disturbance in the rhythmicity of the work. The bioelectric activity of working muscles increased by 1.5-2 times after a 1-3 day exposure to limited muscular activity. After a more prolonged exposure of man to muscular inactivity the bioelectric activity of the working muscles was reduced in comparison with control tests before the start of the experiment. (Author)
