Abstract

Background: Examination stress is a very well-known model of psychological stress in students. It induces changes in systolic (SBP) and diastolic blood pressure (DBP), along with changes in heart rate variability (HRV) and baroreflex sensitivity (BRS), due to autonomic perturbations.

Purpose: To find out if Raj Yoga meditation (RYM) practice affects autonomic and cardiovascular function in healthy young subjects during periods of examination stress. Our primary objective was to evaluate the effect of one month of supervised RYM practice on ameliorating examination-induced changes in cardiovascular and autonomic function. The secondary objective was to measure the stress levels of medical students before and after RYM.

Methods: Pre-training measurements of SBP, DBP, HRV, and BRS were done, and the Medical Student Stressor Questionnaire (MSSQ) was administered to 80 participants one month before examinations. They were then trained in RYM. Post-training assessment of the same parameters was done after examinations and also after two months.

Results: In our study, RYM training decreased DBP (p = 0.01) but not SBP. BRS showed a trend towards an increase after RYM practice, but it was not statistically significant (p = 0.44). The standard deviation of the NN interval (SDNN) (p = 0.03), low-frequency (LF) nu (0.003), and high-frequency (HF) nu (0.04) showed a statistically significant change. Average RR, median RR, average rate, square root of the mean squared differences of successive NN intervals (RMSSD), pRR, total power, LF (µs2), and LF/HF ratio were not statistically significantly different between the three groups. There was a statistically significant decline in MSSQ scores for MSSQ I (p = 0.04), MSSQ II (p = 0.04), and MSSQ IV (p = 0.03).

Conclusion: Short-term practice of supervised RYM during stressful periods is protective for the cardiovascular and autonomic systems and decreases stress in medical students.

冥想在改善考试压力引起的心血管和自主功能变化中的作用。
背景:考试压力是一种众所周知的学生心理压力模型。由于自主神经扰动,它会引起收缩压(SBP)和舒张压(DBP)的变化,以及心率变异性(HRV)和压力反射敏感性(BRS)的变化。目的:了解Raj瑜伽冥想(RYM)练习是否会在考试压力期间影响健康年轻受试者的自主神经和心血管功能。我们的主要目的是评估一个月的RYM监督实践对改善检查引起的心血管和自主神经功能变化的影响。第二个目的是测量RYM前后医学生的压力水平。方法:在训练前测量SBP、DBP、HRV和BRS,并在考试前一个月对80名医学生进行压力源问卷(MSSQ)。然后他们在RYM接受训练。在检查后以及两个月后对相同参数进行训练后评估。结果:在我们的研究中,RYM训练降低了DBP(p=0.01),但没有降低SBP。在RYM实践后,BRS显示出增加的趋势,但没有统计学意义(p=0.44)。NN间期(SDNN)(p=0.03)、低频(LF)nu(0.003)和高频(HF)nu(0.04)的标准差显示出统计学意义的变化。三组之间的平均RR、中位数RR、平均速率、连续NN间期的均方根差(RMSSD)、pRR、总功率、LF(µs2)和LF/HF比率没有统计学上的显著差异。MSSQ I(p=0.04)、MSSQ II(p=0.04)和MSSQ IV(p=0.03)的MSSQ得分在统计学上显著下降。
