目的 探讨不同抗荷加压方案对机体认知能力的影响。方法 使用中文第3版计算机化神经行为测试评价系统（NES-C3）对19名男性受试者在穿抗荷服未加压、穿抗荷服加压、穿定制套带下半身梯度加压三种情况下进行认知能力测试，并在测试后对两种加压方案进行主观感受评价。结果 与抗荷服加压方案相比，梯度加压方案视注意广度、注意力调转、空间位置记忆广度、注意力分配、选择反应时能力值显著升高（均q<0.05），各项测试认知能力值均有提高；小腿部位的压迫感、耐受性、舒适感和大腿部位的耐受性、舒适感、主观感受评分显著升高（均P<0.05）。结论 下半身梯度加压在达到与抗荷服传统加压方案相同抗荷效果时，人体主观感受更为适体，认知能力指数能保持在较高水平。
Abstract：Objective To investigate the effects of different anti-G pressurization protocols on human cognitive performance. Methods The Neurobehavioral Evaluation System-Chinese Version 3(NES-C3) was used to assess the cognitive performence of 19 male subjects under three conditions: wearing an anti-G suit without pressurization(control group), wearing an anti-G suit with pressurization(anti-G suit pressurization group), and wearing a custom-made lower-body graduated pressurization device(graduated pressurization group). Subjective evaluations of the two pressurization protocols were collected following the tests. Results Compared with the anti-G suit pressurization group, the graduated pressurization group showed significantly higher scores in visual attention span, attention switching, spatial memory span, divided attention, and choice reaction time(all q<0.05), indicating improved cognitive performance across all tested domains. Furthermore, subjective ratings of compression sensation, tolerance, and comfort in the calf region, as well as tolerance and comfort in the thigh region, were significantly higher in the graduated pressurization group(all P<0.05). Conclusion When achieving the same anti-G effect as a conventional pressurization protocol, the lower-body graduated pressurization protocol provides superior subjective comfort while maintaining a higher level of cognitive performance.
