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(P<0.01);HP动作的抗荷效果分别为(1.83±0.49)G和(1.92±0.56)G(P<0.01)。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(P<0.01)。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(P<0.05或P<0.01)。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。
Objective To establish a combination of HP and PHP action and new machine anti-charge oxygen equipment technology. Methods Experiments were conducted to study the combination of HP and PHP action with anti-LOX equipment. Six subjects were tested for HP action combined with anti-charge clothing, PHP action combined with anti-LO equipment, and 6.5 G Sustained 45s anti-charge performance, and 8G sustained 15s anti-load performance experiment Gz endurance, heart rate (HR), respiratory rate (BR), lower extremity pedicle force (Flegs) and other indicators of change. Results HP combined with KH-X anti-kimono was able to achieve endurance of 7.25 ± 0.39 G and (7.13 ± 0.59) G, respectively. The anti-load performance of KH-X and DC-X were (2.04 ± 0.10) G (P <0.01). The anti-Dutch effect of HP was (1.83 ± 0.49) G and (1.92 ± 0.56) G respectively (P <0.01). PHP endurance combined with KH-X anti-dutch clothing, DC-X anti-dutch clothes and oxygen equipment reached endurance of (7.13 ± 0.21) G and (7.08 ± 0.20) G, respectively; 0.13) G and (2.17 ± 0.20) G (P <0.01). PHP action combined with KH-X anti-suits, DC-X anti-suits at full load resistance, both reached 6.5 G for 45 s and 8 G for 15 s. The HR and Flegs at the end of each endurance increased significantly with the increase of G (P <0.05 or P <0.01). Conclusion The combination of HP and PHP action and new machine anti-load oxygen supply equipment is scientific and reasonable. It not only gives full play to anti-load effect of equipment, but also can rationally allocate physical strength, saving both physical strength and good anti-load protective performance.
