【摘要】：目的:应用心理生理的监测方法,在海拔3700m现场使用HZY-1型单兵高原增氧呼吸器对负荷运动后的健康青年士兵进行脑-体能力评价,验证HZY-1型单兵高原增氧呼吸器在高原低氧、低气压环境中对人体生理效能的干预效果。方法:实验于2005-06选择进驻西喀喇昆仑山海拔3700m20d的某部健康青年士兵12名,均自愿参加本实验。①12名青年士兵使用HZY-1型单兵高原增氧呼吸器进行自行车功量仪负荷运动,负荷功率250W,心率175～180次/min。②运动10min后,采用电脑多项生理能力测试仪进行两手交叉敲击动作频率检测,规定时间为10s,当提示声响后,受试者立即用左右手分别交叉按动左手键和右手键,先左后右,以最快的速度敲击按键,规定时间到达后,有提示音提示,电脑自动打印出总时间、总次数、正确次数和错误次数。③视觉注意分配能力检测,规定时间为30s,当提示声响后,受试者注视主机面板中部的12个同样颜色的灯键,看到其中1个灯亮时,立即用右手食指按灭,紧接着另一灯点亮,再迅速按灭,以此规则快速进行,测验时间到达时,有提示声响,电脑自动打印出总时间、总次数、正确次数和错误次数。④10d后,不使用增氧呼吸器进行自行车功量仪负荷运动,运动10min后,重复上述两项心理能力测验。测试均在每天10:00-13:30进行。对前后两次测试结果进行统计学对比。结果:按意向处理分析,实验选用健康青年士兵12名,全部进入结果分析。与不带增氧呼吸器负荷运动后比较,带增氧呼吸器负荷运动后的两手交叉敲击动作频率总次数、正确次数均显著增加[(79.0±19.9),(97.1±16.0)次;(77.9±20.3),(94.0±15.0)次;P均0.05],且错误次数显著减少[(2.8±2.1),(0.8±1.7)次,P0.05];带增氧呼吸器负荷运动后视觉注意分配的总次数、正确次数均显著增加[(61.1±9.0),(68.4±6.5)次;(54.7±7.4),(60.6±4.5)次;P均0.05],且错误次数显著减少[(7.4±8.0),(1.7±2.8)次,P0.05]。结论:高原低氧低气压导致人体运动能力下降,负荷运动后使机体缺氧加重,生理功能降低。使用HZY-1型高原增氧呼吸器进行同等负荷运动后,能显著提高和改善海拔3700m移居者的脑-体运动能力。
[Abstract]:Objective: to evaluate the brain-body ability of healthy young soldiers after load exercise by using HZY-1 type single soldier high altitude oxygenation respirator at 3700m above sea level, and to verify that HZY-1 type single soldier plateau oxygenation respirator was used at high altitude hypoxia. Effect of intervention on physiological efficacy of human body in low pressure environment. Methods: in June 2005, 12 healthy young soldiers who were stationed at 3700m20d in West Karakoram Mountain were enrolled in this experiment. All of them volunteered to take part in cycling load exercise with HZY-1 type single soldier altitude oxygenation respirator. After the load power of 250W, the heart rate of 175rpm / min.2 10min, the frequency of the two-hand cross-tapping action was detected by the computer multiple physiological ability tester. The specified time was 10s, when the cues sounded, The subjects immediately crossed and pressed the left hand key and the right hand key with the left and right hands, first left and then right, and struck the keys at the fastest speed. After the specified time arrived, there were prompt sounds, and the computer automatically printed out the total time and the total number of times. The correct number of times and wrong times of 3. 3 visual attention allocation ability were tested, the time was 30 s. When the cue sounded, the subjects looked at the 12 light keys of the same color in the middle of the host panel, and when they saw one of the lights on, they immediately pressed the right index finger out with their right hand. Immediately after another light is lit, and then quickly pressed out, this rule is carried out quickly. When the test time arrives, there is a prompt sound, and the computer automatically prints out the total time, the total number of times, the correct number of times, and the number of errors for .410 days. After 10min exercise, the above two psychological ability tests were repeated. The tests were conducted at 10: 00-13: 30 a day. The results of the two tests were compared statistically. Results: according to intention treatment analysis, 12 healthy young soldiers were selected and all of them entered the result analysis. Compared with those without oxygenated respirator, the total frequency of two hands cross tapping after load exercise with oxygenated respirator was calculated. The correct times increased significantly [(79.0 卤19.9), (97.1 卤16.0) times; (77.9 卤20.3), (94.0 卤15.0) times, P 0.05], and the number of errors significantly decreased [(2.8 卤2.1), (0.8 卤1.7) times P0.05]. The correct times increased significantly [(61.1 卤9.0), (, 68.4 卤6.5); (54.7 卤7.4), (, 60.6 卤4.5) times, P 0.05], and the number of errors decreased significantly [(7.4 卤8.0), (, 1.7 卤2.8) times, P0.05]. Conclusion: hypoxia and hypobaric pressure at high altitude lead to the decrease of human body's movement ability, the hypoxia and physiological function are aggravated after load exercise. After the same load exercise with HZY-1 type high altitude oxygenated respirator, the brain-body motor ability of the migrants at 3 700 m above sea level could be significantly improved.
