摘要

介绍。本研究的目的是评估在压力条件下表现为适应不良和过度焦虑的初中生的心血管系统功能储备状态。研究材料和方法。在初始阶段,70名女学生接受了Cohen和Spielberger的标准化问卷调查。根据调查结果,分为有适应不良和过度焦虑症状的女生为主组(n = 26)和调查结果为阴性的对照组(n = 12)。两组女生年龄相同,体质指数相同。在研究的第二阶段,根据康奈尔协议,研究两组女孩在心脏压力测试(CST)测试时的心血管系统指标。同时测定心率(HR)、收缩压(SBP)、舒张压(DBP)、搏量(CV)、分钟血容量、心脏变时性和收缩性储备指数。研究的结果。结果表明,与对照组(147.92±6.86)W的平均耐受性相比,主组女生对CST的耐受性(103.85±4.43)W有所下降。主组患者心率、分钟血容量、收缩压早期升高,肌力和变时储备指标下降,呈双产物,提示应激限制系统调节机制存在隐蔽性紊乱。主组女生血液动力学变化与抗压能力低、焦虑过度相关。同时,对照组女学生在SCT晚期血流动力学指标发生变化,表明神经体液储备状态较好。结论。通过使用诊断测试和功能测试及时发现青春期体内平衡失调及其后果,将有可能发现青春期女孩的适应失调和可能的身心疾病,并制定预防这些疾病或减少临床表现和改善生活质量的方法,包括学习过程和进一步的专业活动。

THE FUNCTIONAL STATE OF THE CARDIOVASCULAR SYSTEM IN THE CONDITIONS OF A STRESS TEST IN JUNIOR FEMALE STUDENTS WITH MANIFESTATIONS OF PSYCHO-EMOTIONAL IMBALANCE
Introduction. The purpose of the study is to assess the state of the functional reserves of the cardiovascular system in junior female students with manifestations of maladaptation and excessive anxiety in conditions of stress. Research materials and methods. At the initial stage, 70 female students were examined using standardized questionnaires by Cohen and Spielberger. Based on the results of the survey, the main group of girls (n = 26) with signs of maladjustment and excessive anxiety, and the control group with negative survey results (n = 12) were formed. Female students in both groups were of the same age and had the same body mass index. At the second stage of the study, indicators of the cardiovascular system were studied among girls of both groups at the height of the cardiac stress test (CST) test according to the Cornell protocol. At the same time, the heart rate (HR), systolic (SBP) and diastolic blood pressure (DBP), the stroke volume (CV), minute blood volume, and the index of the chronotropic and inotropic reserves of the heart were determined. Research results. It was established that the girls of the main group had a decrease in the tolerance of the CST to (103.85 ± 4.43) W, against the average indicator of (147.92 ± 6.86) W in the control group. The result obtained in the main group was accompanied by an early increase in HR, minute blood volume, SBP, and a decrease in indicators of inotropic and chronotropic reserves, a double product, which indicated the presence of hidden disorders of the regulatory mechanisms of the stress-limiting system. Changes in hemodynamics detected in female students of the main group correlated with low stress resistance, excessive anxiety. At the same time, in the control group of female students, hemodynamic indicators underwent changes at the late stage of the SCT, which indicated a better state of neurohumoral reserves. Conclusion. Timely detection of homeostasis disorders in adolescence and their consequences through the use of diagnostic tests and functional tests will make it possible to detect adaptation disorders and possible psychosomatic conditions in adolescent girls and to develop ways to prevent them or reduce clinical manifestations and improve the quality of life, including the learning process and further professional activity.
