放松训练对心率、T波幅度、心算成绩的影响研究

本实验目的在于探讨放松训练对正常状态和心算应激时心率、T波幅度的影响。实验组接受放松训练,控制组不接受放松训练。结果发现：放松训练使身体常态时的心率显著降低,对心算应激时的心率和T波无显著影响;放松训练降低了心算时心率和心算错误率的方差;实验组的心算速度快,与控制组比较有显著差异。     

腹式呼吸和人格对心率变异性(时域)的影响

1　前言心率变异性 (HRV)分析 ,是一种无创的反映植物神经系统功能的检查方法 ,它反映自主神经系统对心血管系统的调控 ,是目前评价心脏自主神经功能失调的有效方法 ,对指导疾病的治疗及判断某些疾病的预后有重要价值。A型人格在一定程度上影响个体的心率变异性 ,Madi ganMF等人 (1997)研究表明 ,A型人格的个体在愤怒情绪的影响下 ,即使是在实验室睡眠期间 ,也表现出较大的心率变异性。还有研究表明 ,A、B型人格的个体在交感、迷走神经平衡方面存在显著差异 ,A型人格的个体表现出交感神经活动占优势 ,心迷走神经功能减弱。有的研究者也…     

呼吸训练对心血管反应性及指温影响的研究

Delmonte(1985)的研究发现,静默可以使被试的心率、血压水平、皮肤电阻水平显著下降。Hans Zeier(1984)的研究也得到了类似的结果。Kistler(1998)等人认为指尖温度是自主神经系统活动反应的指标。Gwent,Pearson等人(1991)在进行心率研究时发现。内倾者比外倾者表现出较大的反应。我们在行为治疗中发现。腹式呼吸可以使被试手指温度持续上升。升高的时间和保持长度优于自生训练,皮肤温度升高与心血管反应性有关,为探讨腹式呼吸对心血管反应性的影响而提出本课题。     

腹式呼吸对皮肤温度影响的初步探讨

1　问题的提出　　自主神经系统分为交感神经系统和副交感神经系统 ,这两个系统交互抑制。Cannon(1936 )等人的研究已经证明 :心理压力 (stress)和情绪应激可使自主神经系统发生改变 ,从而导致心率、心输出量、血压等发生明显的变化。目前 ,随着生活节奏的加快 ,引起应激的因素越来越多 ,遭受紧张刺激在人生中是不可避免的。所以人们找出一些放松方法来应对应激引起的生理反应。腹式呼吸就是激发放松反应的有效途径之一。交感神经系统支配着血管壁的平滑肌 ,使之产生舒张和收缩 ,其兴奋性下降 ,手指血管平滑肌舒张 ,手指血流量增大 ,手温升…     

不同干预方法对应激时身心状态的影响

选取72名被试,随机分配到对照组、腹式呼吸组和忽视调节组中。采用重复一个因素的三因素混合实验设计,测量被试基线期、干预期、应激期、恢复期的指温、收缩压和应激前后的主观感受,探讨不同干预方法对应激的干预效果。结果表明,腹式呼吸能够降低男生的心血管反应,忽视调节能够降低女生的主观体验,同时也表明,个体生理反应升高并不必然伴随主观体验的升高。

本研究试用生物反馈放松训练和表象训练相结合方法,减轻飞行学员的精神紧张及有关的生理反应、２６名２０—２２岁的男性飞行学员,实验、对照组各１３名、实验组学员每次飞行后进行一次肌电生物反馈放松训练和起落航线表象训练,共１６次;对照组学员参加日常飞行训练不加任何干预。实验前后实验组及对照组学员进行黑红数字测试,记录其测试前后的血压、心率;第一次升空及单飞考核飞行后也记录他们的血压和心率。结果表明,实验组学员的单飞考核成绩优于对照组;实验织学员单飞考核后的收缩压及第二次黑红数字测试后的收缩压比实验前显著降低;而对照组的前述生理指标无变化。生物反馈放松训练和表象训练能有效地减轻飞行中的紧张情绪及其生理反应,适于在飞行部队应用。     

心算对内外倾者的心率、T波幅度和呼吸频率的影响

该文旨在探讨内、外倾者在三种不同难度心算时,心率、Ｔ波幅度、呼吸频率变化的差异。通过艾森克个性问卷筛选出１５名内倾者和１５名外倾者作为被试,让其完成三种不同难度的心算任务。实验结果表明,心算时两组被试心率均显著上升,内倾组上升幅度大于外倾组;Ｔ波幅度显著降低,内倾组降低幅度大于外倾组但差异不显著;呼吸频率显著上升,但两组上升幅度差异不显著。此外,从心率变化上看,两组被试对心算均表现出适应,内倾组的适应速度比外倾组慢。本实验表明,焦虑性精神紧张比智力操作性精神紧张对心率的影响更大。

Effects of different psychological interventions on neck,shoulder and low back pain in female hospital staff

Abstract

One hundred and eleven females volunteered to take part in this intervention study of musculoskeletal pain. They all completed a survey of pain among five hundred and eighty-six female hospital staff and presented mild to severe pain in the neck, shoulder and/or low back. They were randomly assigned to one of the following groups; Focus on job-stress and psychosocial coping (Cognitive), relaxation training (Relaxation), the combination of the two (Combined) or to a control group (Control). Musculoskeletal pain (intensity and duration) was assessed by self-report prior to interventions, immediately after interventions, and at a four months follow-up. Results from multivariate analyses of variance as well as covariance (pre-intervention levels of pain as covariate) showed that magnitude of pain reduction was dependent upon the interaction between area of the back and type of intervention. These trends were more significant for intensity than for duration scores. They were due to reductions of pain in (1) neck and shoulders for the Cognitive and Combined groups and (2) in the low back and shoulders for the Relaxation group. The four month follow-up assessment revealed a significant risk of relapse only for duration of low back pain among subjects in the Combined group. Results from the Cognitive approach to intervention may reflect a causal role for ability to cope with psychosocial job stress in the development of neck and shoulder pain in female hospital staff.     

The effects of attentional training on physiological stress recovery after induced social threat

Abstract

Social stress has been related to both physiological and psychological responses. The recovery of stress is influenced by the way environmental information is processed, i.e., what information is attended to and how it is interpreted. The present study investigated the effect of attention modification training on physiological stress recovery following induced stress. A group of applicants preparing for a job interview were randomly allocated to an attention training condition versus a control condition. Afterwards, they were asked to give an artificial job interview to a real life jury while being videotaped. Participants in both conditions showed decreased heart rate variability during the job interview, which indicates an overall physiological stress response. However, during a 30-minute follow-up period after the training, indices of heart rate variability showed improved stress recovery only in the attention training condition. Attentional training is proposed as a promising strategy to prevent enduring stress reactions.     

Heart rate during group flooding therapy for PTSD

The objective of this study was to assess, via heart rate, the arousal levels of participants in group trauma reexposure therapy for posttraumatic stress disorder, and so to better understand this common mode of treatment, particularly in regards to its presumed curative factor, extinction. Six Vietnam combat-related PTSD inpatients participated twice weekly in group trauma reexposure therapy during which their electrocardiograms were recorded. Heart rate was quantified continuously off-line. Heart rates of participantsnot directly engaged in imaginal reexposure to their personal combat traumas consistently exhibited mild linear declines from the beginnings to the ends of the approximately 2.5 hour sessions. Participants actively engaged in personal combat trauma reexposure exhibited higher whole-session heart rates. Most also exhibited more specific elevation extending over the later portions of therapy sessions during which intensive reexposure usually occurred. Surprisingly, no patients exhibitedfocal increases in heart rate concurrent with periods of most intensive traumatic incident review as judged from videotape. Administering imaginal reexposure in a group context does not preclude substantial physiological (sympathetic) arousal, as is preconditional for extinction. Under conditions in which the actively engaged reexposure patient is reliably identified, group trauma reexposure therapy may not provide an opportunity for “vicarious” flooding in nonengaged participants.

选取38名大学生为被试,采用BIOPAC多导生理记录仪,探讨心算应激对不同人格特质和应对风格的大学生心率（HR）、心率变异性（HRV）及皮肤电反应（GSR）的影响。实验采取2（人格特质：特质焦虑、非特质焦虑）×2（应对风格：注重情绪的应对、注重问题的应对）×3（实验阶段：基线期、任务期、恢复期）的三因素混合设计,要求所有被试经历5分钟的基线期、10分钟的心算任务期和5分钟的恢复期。结果表明：（1）特质焦虑的个体和注重情绪应对的个体在心算应激后的短时间内难以恢复到基线期的生理水平;（2）特质焦虑且注重情绪应对的个体在HR、HF、LF/HF及GSR上表现出明显强的反应性和弱的恢复性;（3）非特质焦虑且注重问题应对的个体在HF和GSR上表现出明显弱的反应性,在LF/HF和GSR上表现出明显强的恢复性。     

EFFECTS OF RELAXATION TRAINING ON PULMONARY MECHANICS IN CHILDREN WITH ASTHMA1

An experiment, designed to overcome shortcomings in previous work, was conducted to investigate the potential symptomatic benefits of relaxation training in the treatment of asthma in children. Fourteen chronic, severely asthmatic children received three sessions in which they rested quietly, followed by five sessions of relaxation training, and finally three sessions of relaxing as trained previously. Pulmonary function was assessed, in a manner far more definitive than in previous studies, before and after each session, and three additional times at 30-minute intervals thereafter. Tension in the frontales muscles, heart and respiration rates, and skin temperature and conductance were also monitored. Heart rate and to some extent muscle tension results tended to confirm the attainment of relaxed states. However, the lung function results failed to substantiate the previous, preliminary findings of a clinically meaningful change in pulmonary function following relaxation. The status of relaxation in the treatment of asthma was discussed.
