不同G_Z值旋梯训练对飞行学员心率及呼吸频率的影响

Effect of Different G_Z Value Ladder Training for Pilots' Heart Rate and Respiratory Frequency

目的:利用航空体育器械——旋梯,脚部位旋转至垂直于地面瞬间承载1Gz、2Gz、3Gz、4Gz、5Gz、6Gz负荷锻炼,观察训练后即刻、3 min、10 min心率及呼吸率的变化。方法:4名2016级飞行技术专业学生,第一次测试1Gz、6Gz负荷,各锻炼30 s后即刻、3 min、10 min心率及呼吸频率情况;间隔一天,第二次测试2Gz、5Gz负荷,各锻炼30 s后即刻、3 min、10 min心率及呼吸频率情况;间隔一天,第三次测试3Gz、4Gz负荷,各锻炼30 s后即刻、3 min、10 min心率及呼吸频率情况。采用腕带式电子血压计测量心率,采用两人观察计数方法记录呼吸频率。结果被试者1Gz、2Gz锻炼强度训练下,30 s训练后即刻心率及呼吸频率上升但未见显著性;在3Gz强度锻炼下,训练后即刻心率及呼吸频率呈现显著上升(P<0.05),休息3 min后心率、呼吸频率恢复到安静心率水平;被试者4Gz、5Gz、6Gz负荷锻炼训练下,30 s训练后即刻心率及呼吸频率呈现显著上升(P<0.01),训练负荷越大上升幅度越大,休息3 min后心率与安静水平比较,显著上升(P<0.05),休息3min后呼吸频率与安静水平比较,显著增加(P<0.05、P<0.01),休息10 min后心率及呼吸频率恢复到安静水平。

Purpose 7-by using aviation sports equipment - foot ladder, rotate to the vertical to the ground instantly, and do the 2Gz, 3Gz, 1Gz carrying 4Gz, 5Gz, 6Gz load exercise, then observe post training 3min, 10min, change of heart rate and respiratory rate. Methods-Let four student pilots of 2016 do the first test 1Gz, 6Gz load, the exercise immediately after 30s, 3rain, 10min, heart rate and respirato- ry rate, after the interval of one day, secondly test 2Gz, 5Gz load, the exercise immediately after 30s, 3min, 10min, heart rate and respiratory frequency, and after another interval one day, thirdly test 3Gz, 4Gz load, the exercise immediately after 30s, 3min, 10min, heart rate and respiratory frequency, using the wrist electronic sphygmomanometer with heart rate, two people were counting records of respiratory frequency. Results -the subjects 1Gz, 2Gz exercise training, 30s training immediately after, heart rate and respiration rate increased but not significantly; in the 3Gz exercise intensity, heart rate and respirato- ry frequency immediately after training showed a significant increase （P〈 0.05）, 3min after resting heart rate and respiratory frequency recovery to heart rate level subjects; 4Gz, 5Gz, 6Gz load exercise training, 30s training after the heart rate and respiratory frequency was increased significantly （P〈 0.01）, the greater the training load increase more, rest after 3min and quiet heart rate level, increased significantly（P〈 0.05）, compared with the level of quiet rest 3min the respiration rate, increased significantly （P〈 0.05, P〈 0.01）, 10min after resting heart rate and respiration rate back to quiet level.
