前言 据报道,负性G2(-Gz)有加速度后紧接的不良的效应——降低正性Gz(+Gz)的耐力。另外,飞行中失能危险的增加可归因于它对压力感受器代偿机制的损害。本研究的目的是调查在低水平Gz转换和L-1动作下的心血管负荷。方法 30名志愿者根据他们对L-1动作了解程度被分为两组:飞行人员组(9名)和地勤人员组(21名)。在试验阶段,每个受试者开
It has been reported that the negative G2 (-Gz) has an immediate adverse effect after acceleration - reducing the endurance of the positive Gz (+ Gz). In addition, the increased risk of in-flight disability can be attributed to its damage to the baroreceptor compensatory mechanism. The purpose of this study was to investigate cardiovascular load at low levels of Gz switching and L-1 motility. Methods Thirty volunteers were divided into two groups based on their knowledge of L-1 motions: Flight Crew (9) and Ground Crew (21). In the experimental phase, each subject opened
