正常组1′后植物神经的调节水平处于相对稳定和相对平衡状态。阳性组各阶段均是交感神经紧张度占优势的不平衡与站位下其紧张程度随站立时间延长而逐渐增加的不稳定状态。阳性组植物神经系统对立位耐力试验的反应,可能与其副交感神经紧张度(功能)降低有关。
The regulation level of autonomic nerve in the normal group 1 ’is in a relatively stable and relative equilibrium state. Positive stages of the group are sympathetic tone-dominated imbalances and stations under the tension with the standing time gradually increased and unstable state. The response of the positive plant nervous system to the standing endurance test may be related to the reduction of parasympathetic tone (function).
