摘要
目的探讨训练倦怠与新入伍军人应激条件下心血管反应间的关系以及社会支持的中介作用。方法2019年9月,随机抽取进疆387名新入伍军人作为研究对象,采用训练倦怠自评问卷、领悟社会支持量表,以舒张压(DBP)、收缩压(SBP)、心率(HR)为测试指标,中介作用采用结构方程模型进行分析。结果新入伍军人测试任务期心率、收缩压、舒张压高于基线期、结束期,差异均有统计学意义(F=138.516、88.436、96.347,均P<0.01)。新入伍军人应激时的心率反应与身心耗竭、低成就感、训练倦怠、社会支持呈显著负相关(r=-0.172、-0.119、-0.116、-0.144,均P<0.05)。社会支持在训练疏离与应激时心率反应间具有完全中介作用,其95%CI为(0.181~0.466);社会支持在身心耗竭与应激时心率反应间具有部分中介作用,其95%CI为(0.077~0.301)。结论新入伍军人的心率、血压易受到应激影响,社会支持在身心耗竭、训练疏离与应激时心率反应间具有中介作用。
Objective To explore the association between training burnout and cardiovascular response of new military recruits under stress,as well as the mediating effect of social support.Methods A total of 387 new military recruits in Xinjiang were enrolled randomly in September 2019,and were evaluated by training burnout self rating questionnaire and perceived social support scale.Meanwhile,the systolic blood pressure(SBP),diastolic blood pressure(DBP),and heart rate(HR)were measured.Structural equation modeling was used to assess the mediating effect.Results The levels of SBP,DBP and HR of new recruits in the test task period were higher than those in the baseline period and the end period,and the differences were statistically significant(F=138.516,88.436,96.347,all P<0.01).The heart rate response to stress of new recruits was significantly negatively correlated with physical and mental exhaustion,low sense of achievement,training burnout and social support(r=-0.172,-0.119,-0.116,-0.144,all P<0.05).Social support played full mediating effect between training depersonalization and HR response in new military recruits under stress(95%CI:0.181-0.466),while partial mediating effect of social support was noticed between emotional exhaustion and HR response(95%CI:0.077-0.301).Conclusion The heart rate and blood pressure of new military recruits respond to stress.Social support has mediating effect between emotional exhaustion,training depersonalization and heart rate response under stress.
