摘　　要：目的开展载人离心机慢增长率(gradual-onset rate run,GOR)模式+G_(z)耐力检查试验研究,探讨该方法在综合抗荷措施防护效果评定中的应用。方法6名男性受试者在载人离心机上进行了GOR加速度暴露试验,每人均完成4组:不使用抗荷装备,保持松弛状态的加速度耐力(GOR1耐力),做HP抗荷动作时的加速度耐力(GOR2耐力),穿抗荷服保持松弛状态的耐力(GOR3耐力),做HP动作、穿抗荷服使用抗荷加压呼吸时的耐力(GOR4耐力)。依次检查受试者在4组+G_(z)暴露时的加速度耐力及心率和呼吸频率,受试者对体力感知度评价表进行评分,试验结束后填写调查问卷,对抗荷装备的防护效果进行了主观评价。结果6名受试者GOR1耐力为(4.21±0.99)G,GOR2耐力为(6.00±1.32)G,GOR3耐力为(6.34±1.32)G,GOR4耐力为(7.87±1.29)G,不同GOR模式+G_(z)暴露的耐力差异有统计学意义(F=174.477,P<0.001)。受试者在4组+G_(z)暴露试验到达耐力终点的心率及HR_(max)差异有统计学意义(F=131.330、128.417,P均<0.001);GOR2和GOR4的心率(P=0.013、0.017)及HR_(max)显著大于GOR1(P=0.014、0.006);GOR2与GOR4的HR_(max)差异有统计学意义(P=0.006)。HP抗荷动作防护效果为(1.79±0.88)G,AGS防护效果为(2.13±1.03)G,综合抗荷措施的防护效果为(3.67±0.80)G。综合抗荷措施的防护效果大于做HP抗荷动作及AGS(P=0.001、0.003),但HP抗荷动作与AGS防护效果比较差异无统计学意义(P=0.301)。受试者对抗荷装备防护效果的主观感觉评分达到“较好”水平。结论在综合抗荷措施防护效果评定时增加载人离心机GOR模式+G_(z)耐力检查方法有助于进一步提高评定结果的准确性。Objective To carry out an experimental study on gradual-onset rate(GOR)run acceleration tolerance measurement and on the applicability of this method in evaluation of combined anti-G measures.Methods Six male subjects were exposed to GOR runs on a human centrifuge.The acceleration tolerance,heart rate and respiratory rate were measured in four+G_(z) runs:staying relaxed without anti-G equipment(GOR1);performing HP maneuver(GOR2);staying relaxed when wearing an anti-G suit(AGS)(GOR3);performing HP maneuver when wearing an AGS and using positive pressure breathing for G(PBG)(GOR4).Ratings of perceived exertion were collected immediately after GOR2,GOR3and GOR4 runs.Questionnaires were completed when the experiment was over.Results The subjects’+G_(z) tolerance of GOR1,GOR2,GOR3 and GOR4 was(4.21±0.99)G,(6.00±1.32)G,(6.34±1.32)G and(7.87±1.29)G respectively,so the difference was significant(F=174.477,P<0.001).The difference in heart rate and HR_(max) at the G tolerance end point was also of statistical significance(F=131.330、128.417,P<0.001).Heart rate(P=0.013、0.017)and HR_(max)(P=0.014、0.006)of GOR2 and GOR4 were greater than those of GOR1 and the difference of HR_(max) between GOR2 and GOR4 was significant(P=0.006).The protection effects of HP maneuver,AGS and combined anti-G measures were(1.79±0.88)G,(2.13±1.03)G and(3.67±0.80)G,respectively.The protection effect of combined anti-G measures was better than that of HP maneuver and AGS(P=0.001、0.003),but the difference in protection effects between HP maneuver and AGS was not significant(P=0.301).The subjective score of anti-G equipment protection effect was relatively high.Conclusion The GOR rate run acceleration tolerance measurement can contribute to the accuracy of evaluating the protection effect of combined anti-G measures.
