【摘要】：目的建立HP与PHP动作与新机抗荷供氧装备结合应用的技术方法。方法实验对HP与PHP动作与新机抗荷供氧装备结合应用的方法进行了设计,观察6名受试者在HP动作与抗荷服装结合,PHP动作与抗荷供氧装备结合,6.5 G持续45 s抗荷性能,以及8 G持续15 s抗荷性能实验时+Gz耐力、心率(HR)、呼吸率(BR)、双下肢蹬力(Flegs)等指标的变化。结果 HP动作结合KH-X抗荷服,DC-X高空代偿服的耐力分别达到(7.25±0.39)G,和(7.13±0.59)G;KH-X和DC-X的抗荷性能均为(2.04±0.10)G(P0.01);HP动作的抗荷效果分别为(1.83±0.49)G和(1.92±0.56)G(P0.01)。PHP动作结合KH-X抗荷服、DC-X高空代偿服及供氧装备的耐力分别达到(7.13±0.21)G和(7.08±0.20)G;PHP动作的抗荷效果分别为(2.17±0.13)G和(2.17±0.20)G(P0.01)。PHP动作结合KH-X抗荷服,DC-X高空代偿服的综合抗荷耐力,均达到6.5 G持续45 s及8 G持续15 s。各耐力终点时的HR,Flegs随G值增加而显著升高(P0.05或P0.01)。结论 HP与PHP动作与新机抗荷供氧装备结合应用的方法科学合理,既充分发挥了装备的抗荷效果,又可以合理分配体力,既节省体力,又具有良好抗荷防护性能。
[Abstract]:Objective to establish the technique and method of combining HP and PHP action with new machine anti-load and oxygen supply equipment. Methods the method of combining HP and PHP action with new machine anti-G oxygen equipment was designed experimentally. Six subjects were observed in the combination of HP action and anti-G clothing, PHP action and anti-G oxygen supply equipment combined with 6.5G continuous anti-G anti-load performance. The changes of G _ z endurance, heart rate and HRN, respiration rate BRN and leg pedaling force Flegswere also studied during the test of 8 G continuous 15 s. Results the endurance of HP exercise combined with KH-X antiG suit DC-X was 7.25 卤0.39g, and that of 7.13 卤0.59g + KH-X and DC-X were 2.04 卤0.10g / 0.01G and 1.92 卤0.56g respectively. PHP combined with KH-X / DC-X was 1.83 卤0.49g and 1.92 卤0.56g respectively. The endurance of the two groups reached 7.13 卤0.21g and 7.08 卤0.20g, respectively. The anti-G effects of PHP action were 2.17 卤0.13G and 2.17 卤0.20g / g respectively. PHP combined with KH-X anti-G suit DC-X high-altitude compensatory wear had comprehensive anti-G endurance. The mean duration was 6.5 G for 45 s and 8 G for 15 s. HRP Flegs at each endurance end point increased significantly with the increase of G value (P 0.05 or P 0.01). Conclusion the method of the combination of HP and PHP action and the new anti-load and oxygen supply equipment is scientific and reasonable. It can not only give full play to the anti-load effect of the equipment, but also reasonably distribute the physical strength, save physical strength and have good anti-load protection performance.
