■由于工作场所的压力因素,紧张而持久的办公室工作是导致肌肉和精神障碍的常见原因。正念和缓慢的呼吸练习减少心理压力,改善心理健康,而快速呼吸增加神经元兴奋性。本研究旨在探讨5分钟正念呼吸(MINDFUL)的影响,慢呼吸(SLOW),快速呼吸(FAST),在密集的心理任务中听音乐(MUSIC)关于肌肉紧张和执行功能。
■48名参与者(24名男性和24名女性)参加了研究。使用表面肌电图记录肌肉张力,使用Stroop颜色和单词测试(Stroop测试)评估执行功能。呼吸率(RR),氧饱和度(SpO2),潮气末二氧化碳(EtCO2),和受试者的首选方法也被记录。在实验过程中,参与者进行一次基线测试(观看5分钟的中性视频),然后完成5分钟的音乐,介意,慢,和FAST在一个随机序列。每次干预后进行Stroop测试,包括基线测试,然后休息5分钟,然后进行下一次干预。
■没有一种方法对男性和女性的Stroop测试的肌肉活动和表现有显著影响,基于平均5分钟值。然而,第五分钟,男性在Stroop测试中的准确率在SLOW后明显高于MUSIC和FAST后,SLOW后的反应时间最短。SLOW期间的SpO2明显高于音乐期间,SLOW后RR相对低于音乐后。大多数男人更喜欢慢,大多数女性更喜欢音乐,而FAST对男性和女性都是最不利的方法。
■简短的呼吸练习对心理压力下的肌肉紧张没有实质性影响。SLOW显示出更大的维持男性执行功能的潜力,可能是通过其对SpO2的优异呼吸效率和对RR的抑制。
UNASSIGNED: Intensive and long-lasting office work is a common cause of muscular and mental disorders due to workplace stressors. Mindful and slow breathing exercises decrease psychological stress and improve mental health, whereas fast breathing increases neuronal excitability. This study aimed to explore the influence of 5 min of mindful breathing (MINDFUL), slow breathing (SLOW), fast breathing (FAST), and listening to music (MUSIC) on muscle tension and executive function during an intensive psychological task.
UNASSIGNED: Forty-eight participants (24 men and 24 women) were enrolled. Muscle tension was recorded using surface electromyography, and executive function was assessed using the Stroop Color and Word Test (Stroop Test). The respiration rate (RR), oxygen saturation (SpO2), end-tidal carbon dioxide (EtCO2), and the subjects\' preferred method were also recorded. During the experiment, participants performed a one-time baseline test (watching a neutral video for 5 min) and then completed 5 min of MUSIC, MINDFUL, SLOW, and FAST in a random sequence. The Stroop Test was performed after each intervention, including the baseline test, and was followed by a 5 min rest before performing the next intervention.
UNASSIGNED: None of the methods significantly influenced muscular activity and performance of the Stroop Test in both men and women, based on the average 5 min values. However, at the fifth minute, men\'s accuracy rate in the Stroop Test was significantly higher after SLOW than after MUSIC and FAST, and the reaction time after the SLOW was the shortest. SpO2 was significantly higher during SLOW than during MUSIC, and RR was relatively lower after SLOW than after MUSIC. Most men preferred SLOW, and most women preferred MUSIC, whereas FAST was the most unfavorable method for both men and women.
UNASSIGNED: Brief breathing exercises did not substantially affect muscle tension under psychological stress. SLOW demonstrated greater potential for sustaining executive function in men, possibly via its superior respiration efficiency on SpO2 and inhibition of RR.
