摘要

在为期7天的太空飞行中,研究了姿态的适应和姿态调整涉及手臂的自主抬高。结果显示,在飞行开始时,身体有一个重要的前倾。经过三天的飞行,身体的姿势与地面上的姿势相似。与这种倾斜一起,观察到踝关节屈肌和伸肌之间肌电图活动的重新分布。预期的姿势调整在微重力下总是存在的。这些结果是在体图式的基础上解释的。

[Postural adjustments associated with voluntary mobilization of the arm in microgravity conditions].

Adaptation of posture and of postural adjustments involved in voluntary elevation of the arm was studied during a seven day spaceflight. Results show an important forward inclination of the body at beginning of the flight. After three days in flight the position of the body was similar to the terrestrial posture. Together with this inclination, a redistribution of the electromyographic activities between flexor and extensor muscles of the ankle was observed. Anticipatory postural adjustments were always present in microgravity. These results are interpreted on the basis of body scheme.
