OBJECTIVE
To evaluate the stress level during parachuting training by salivary biomarker and to study the dynamic characteristics.
METHODS
Twenty recruits of military parachuting training completed 8 trainings in a month. The saliva samples were collected at 2 h and 1h before boarding and at 0.5 h after landing on the 1st, 4th and 7th trainings. The levels of cortisol, chromogranin A and α-amylase in saliva samples were detected.
RESULTS
The concentrations of cortisol, chromogranin A and activity of α-amylase increased significantly from pre-boarding to landing during 3 trainings. The concentrations of cortisol, chromogranin A and activity of α-amylase at 2 h before boarding and at 0.5 h after landing decreased significantly with the training times. However, the changes of 3 biomarkers at 1 h before boarding among 3 trainings were not significant.
CONCLUSION
The levels of stress increased significantly for 20 recruits from pre-boarding to landing during parachuting trainings. The stress levels of 20 recruits before boarding and after landing significantly decreased with parachuting training times.
目的
通过唾液生物标志物评估跳伞训练期间的应激水平，并研究其动态特征。
方法
20名军事跳伞训练新兵在一个月内完成8次训练。在第1、4和7次训练登机前2小时和1小时以及着陆后0.5小时采集唾液样本。检测唾液样本中皮质醇、嗜铬粒蛋白A和α-淀粉酶的水平。
结果
在3次训练中，从登机前到着陆，皮质醇、嗜铬粒蛋白A的浓度和α-淀粉酶的活性显著增加。随着训练次数增加,登机前2小时和着陆后0.5小时的皮质醇、嗜铬粒蛋白A浓度和α-淀粉酶活性显著降低。然而，3次训练中登机前1小时这3种生物标志物的变化不显著。
结论
20名新兵在跳伞训练期间从登机前到着陆应激水平显著增加。随着跳伞训练次数增加，20名新兵登机前和着陆后的应激水平显著降低。
