The effect of 21-day exposure to +2 Gx and +1.1 Gx on the contractile properties of different muscle groups of rat fore- and hindlimbs was examined, using glycerinated myofibers in the ATP + Ca2+ solution. It was found that the isometric contraction strength and velocity increased, the performance of the postural extensors also grew: that of the soleus m. in the +2 Gx rats and that of the triceps brachii m. in the +2 Gx and +1.1 Gx rats. The contractile changes of the flexors of fore- and hindlimbs were insignificant and sometimes oppositely directed. The different responses of the muscles to acceleration were associated with the differences in their function, metabolism and biomechanics.
利用ATP + Ca2+溶液中的甘油化肌纤维，研究了21天暴露于+2 Gx和+1.1 Gx对大鼠前肢和后肢不同肌肉群收缩特性的影响。结果发现，等长收缩强度和速度增加，姿势伸肌的性能也有所提高：在+2 Gx大鼠中比目鱼肌的性能提高，在+2 Gx和+1.1 Gx大鼠中肱三头肌的性能提高。前肢和后肢屈肌的收缩变化不明显，有时方向相反。肌肉对加速度的不同反应与其功能、代谢和生物力学的差异有关。
