冷水浸泡(CWI)对身心健康有好处。我们的目的是研究急性CWI对血管切应力和影响(正性和负性)的影响。16名健康成人(年龄：23±4岁；9名男性和7名女性)完成了一次15分钟的CWI(10°C)。所有参与者在CWI前(Pre)、浸泡后30分钟和浸泡后180分钟评估自我报告的情感(积极和消极)。分别于治疗前、治疗后1min、15min及浸泡后30min测量肱动脉内径及血流速度(n=8)。计算总切应力、顺行切应力和逆切应力、振荡切变指数(OSI)和前臂血管电导(FVC)。分别于照射前、照射后1min、15min、浸泡后30min和180min(n=8)采集静脉血，测定血清β-内啡肽和皮质醇的含量。数据分析采用单因素方差分析，采用Fisher‘s最小显着性差异，并与治疗前进行比较。积极情绪在浸泡后180min无明显变化(方差分析p=0.450)，但消极情绪较低(p<；0.001)。在CWI15分钟和浸泡后30分钟，FVC降低(p<；0.020)。浸泡后30min，总切变率、顺行切变率和OSI均降低(p<；0.040)，但逆切变率无显著差异(ANOVA p=0.134)。β-内啡肽在整个试验过程中没有变化(方差p=0.321)。皮质醇在浸泡后180min降低(p=0.014)。CWI的急性发作对切应力模式的影响最小，但可能通过减少负面情绪和皮质醇水平而有益于心理健康。
Cold water immersion (CWI) may provide benefits for physical and mental health. Our purpose was to investigate the effects of an acute bout of CWI on vascular shear stress and affect (positive and negative). Sixteen healthy adults (age: 23±4 y;(9 self-reported men and 7 self-reported women) completed one 15-min bout of CWI (10° C). Self-reported affect (positive and negative) was assessed at pre-CWI (Pre), 30-min post-immersion, and 180-min post-immersion in all participants. Brachial artery diameter and blood velocity were measured (Doppler ultrasound) at Pre, after 1-min and 15-min of CWI, and 30-min post-immersion (n= 8). Total, antegrade, and retrograde shear stress, oscillatory shear index (OSI), and forearm vascular conductance (FVC) were calculated. Venous blood samples were collected at Pre, after 1-min and 15-min of CWI, 30-min post-immersion, and 180-min post-immersion (n= 8) to quantify serum β-endorphins and cortisol. Data were analyzed using a one-way ANOVA with Fisher's least significance difference and compared to Pre. Positive affect did not change (ANOVA p= 0.450) but negative affect was lower at 180-min post-immersion (p< 0.001). FVC was reduced at 15-min of CWI and 30-min post-immersion (p< 0.020). Total and antegrade shear and OSI were reduced at 30-min post-immersion (p< 0.040) but there were no differences in retrograde shear (ANOVA p= 0.134). β-endorphins did not change throughout the trial (ANOVA p= 0.321). Cortisol was lower at 180-min post-immersion (p= 0.014). An acute bout of CWI minimally affects shear stress patterns but may benefit mental health by reducing negative feelings and cortisol levels.
