摘要
目的观察不同训练强度士兵的应激适应能力 ,为进一步提高部队的应激适应能力研究提供科学依据。方法采用抽样调查的方法 ,选取同一地区甲、乙两支训练强度不同的部队作为研究对象 ;比较两部队训练强度、体能及应激反应适应能力之间的差异。结果甲部队士兵动态心率平均值以及最大摄氧量均明显高于乙部队士兵 (P <0 .0 5 ) ,说明甲部队的体能训练强度和士兵体能状况优于乙部队 ,甲部队在同一应激过程中的收缩压、最大心率〔(13.6± 1.2 )kPa ,(89.3± 12 .4 )b·min 1〕均明显低于乙部队的〔(15 .0± 1.70 )kPa ,(95 .2± 15 .9)b·min 1,P <0 .0 1〕 ;而视觉反应时间和记忆字长〔(1393.9± 336 .2 )ms ,(8.2± 1.1)位〕则明显高于乙部队〔(12 84 .2±372 .2 )ms ,(7.9± 1.1)位 ,P <0 .0 5〕。结论体能较好的甲部队在面对同一应激源时 ,应激反应水平较低 ,表现出了较强的应激适应能力 ;而体能较差的乙部队情况则相反。提示 ,适当的提高训练强度 ,有利于战士应激适应能力的提高。
Objective To observe the abilities of adaptation to stress in soldiers with different intensity of training, so as to provide scientific basis for study of further improvement in adaptation to stress. Methods Two troops (A,B) located at the same area with different intensity of exercise were investigated. The intensity of training, physical fitness and the abilities of adaptation to stress were measured and compared. Results The average dynamic heart rate and O 2max in Troop A were greater than those in Troop B, indicating that Troop A had better physical fitness and higher intensity of training. The systolic pressure and maximum heart rate in Troop A〔(13.6±1.2)kPa,(89.3±12.4)b·min 1 respectively〕were lower than those in Troop B〔(15.0±1.70)kPa,(95.2±15.9)b·min 1 respectively,P<0.01〕,but the visual reaction time and temporary memory digit in Troop A〔(1393.9±336.2)ms, (8.2±1.1)respectively〕were higher than those in Troop B〔(1284.2±372.18)ms, (7.9±1.1),P<0.01〕. Conclusion Troop A with higher intensity of training had higher ability of adaptation to stress than Troop B with lower intensity of training, suggesting that properly raise the intensity of training may contribute to the improvement of adaptation to stress in soldiers.
