A novel system for simultaneous measurements of isotonic muscle contraction and transversal muscle belly displacement in the isolated rat soleus muscle was designed. The system simultaneously records tetanic contraction of the muscle and transversal displacements of the muscle belly. The tetanic rise times (TRT) and muscle belly displacement times (BDRT) were measured at different proton loads induced by CO2 at 1%, 5% and 30%. The measurements of muscle belly displacement enabled us to follow the water shift into the muscle tissue during the tetanic activity. Acidosis provoked by 30% CO2 irreversibly increased the BDRT, however the TRT were not changed.
设计了一种用于同时测量离体大鼠比目鱼肌等张肌肉收缩和横向肌腹位移的新型系统。该系统可同时记录肌肉的强直收缩和肌腹的横向位移。在1%、5%和30%的二氧化碳诱导的不同质子负荷下，测量强直上升时间（TRT）和肌腹位移时间（BDRT）。肌腹位移的测量使我们能够追踪强直活动期间水向肌肉组织的转移。30%二氧化碳引起的酸中毒不可逆地增加了BDRT，但TRT没有改变。
