摘要
目的分析参训人员24h海上生存训练生理指标变化特点,为探索海上生存训练的航卫保障方案提供参考依据。方法选取16名有航空救生专业基础的参训人员进行测试,按照跳伞着水时间分为上午组(9:00)和下午组(18:00),检测其24h海上生存前后体成分、血压和尿常规指标,记录其训练过程中饮食、饮水、排尿量、体温和心率等生理指标。结果海上生存训练后,16名参训人员的体质量、去脂体质量、肌肉重量、体水分、体水分率和体质量指数降低(t=5.555~18.944,P均<0.001);体脂肪率(t=3.330,P=0.005)增加;收缩压、舒张压升高(t=5.393、3.706,P<0.001、=0.002);尿液变化中酮体指标异常者4例。上午组和下午组参训人员训练前后的体成分、血压、尿液pH值和尿比重改变差异无统计学意义(P>0.05)。海上生存训练期间,参训人员的饮食量为36.5~292.0g;2名参训人员未饮水,余饮水者最高饮水量500ml;排尿量500~3000ml。皮肤有红疹、瘙痒症状11例。上午组的腋下平均体温总体上均高于下午组,上午组的平均心率低于下午组。上午组和下午组的腋下体温和心率随入水时间而变化,其差异具有统计学意义(F=18.456、29.114,P=0.005、0.001)。结论参训人员24h海上生存训练过程中体温及心率较稳定,训练结束后体质量下降,体水分减少,皮肤不适症状普遍,为针对海上生存训练的航卫保障措施提供参考依据。
Objective To explore the changes of physiological indexes in 24-hour marine survival training,and to provide a reference for exploring health protection methods for marine survival training.Methods Sixteen soldiers welltrained in aviation lifesaving were selected from an Air Force base.They were divided into the morning group(9:00)and the afternoon group(18:00)according to the time of skydiving into the water.Body composition,blood pressure,and urine routines were measured before and after 24-hour marine survival training.The physiological changes of diet,water intake,urine outputs,body temperature,and heart rate were recorded.Results After marine survival training,weight,FFM,muscle mass,tobal body water,tobal body water ratio and BMI of the sixteen soldiers decreased(t=5.555~18.944,all P<0.001)while body fat ratio(t=3.330,P=0.005),systolic blood pressure and diastolic blood pressure(t=5.393,3.706,P<0.001,=0.002)increased.The changes of urine were abnormal in four subjects.There were no statistically significant differences in body composition,blood pressure,urine pH or urine specific gravity between the morning and afternoon groups before and after training(P>0.05).During the marine survival training,the lowest dietary intake was 36.5 g while the highest was 292.0 g.Two of the subjects drank no water,the highest water intake was 500 ml among the rest.The urine outputs ranged from 500 to 3000 ml.Rash and skin pruritus were found in eleven subjects.The average axillary body temperature of the morning group was higher than that of the afternoon group totally in the water.The average heart rate of the morning group was lower than that of the afternoon group.There was statistically significant difference between the morning and afternoon groups in axillary temperature and heart rate that changed with the length of time in the water(F=18.456,29.114,P=0.005,0.001).Conclusion During the 24 hours of marine survival training,body temperature and heart rate were relatively stable.After training,the subjects lost weight,tot
