冷刺激会增加动脉僵硬，但在较凉爽的水中游泳后，动脉僵硬是否会增加，目前还没有研究。为了研究水温对游泳后动脉僵硬变化的影响，13名男性参加了3次随机顺序的游泳试验，分别是在25℃和30℃的水中游泳20min(分别为S25和S30)和坐在池边(CON)。在S25和S30试验中，平均游泳距离(719米比722米)和游泳期间的心率储备(63%比63%)没有显著差异。在25°C水中游泳后，舌下温度低于游泳前。25°C水中游泳30min后，主动脉脉搏波速度(主动脉PWV，基于压平眼压计的中央动脉僵硬指数)和臂踝脉搏波速度(baPWV，基于空气体积描记的全身动脉僵硬指数)均高于游泳前。在25℃水中游泳60min，主动脉PWV恢复至游泳前水平，但baPWV在游泳后60min仍高于游泳前水平。在CON和S30试验中，PWV没有改变。在25°C水中游泳30min和60min后，多普勒超声检测的全身血管阻力无明显变化，而应变仪测定的前臂血管阻力在30min和60min时升高。25℃水中游泳30min后心率较高，但每搏量较低，心输出量无明显变化。总而言之，在较冷的水中进行中等强度游泳后，动脉僵硬会急剧增加。
Cold stimuli increase arterial stiffness, but it has not been explored whether arterial stiffness increases after swimming in cooler water. To investigate the effects of water temperature on changes in arterial stiffness after swimming, 13 men participated in three trials of 20‐min swimming in 25 and 30°C water (S25 and S30, respectively) and sitting at poolside (CON) in random order. There were no significant differences between the S25 and S30 trials in mean swimming distance (719 vs. 722 m) and heart rate reserve during swimming (63% vs. 63%). Sublingual temperature was lower after swimming in 25°C water versus before swimming. Aortic pulse wave velocity (aortic PWV, an index of central arterial stiffness based on applanation tonometry) and brachial‐ankle pulse wave velocity (baPWV, an index of systemic arterial stiffness based on air plethysmography) were higher 30 min after versus before swimming in 25°C water. Aortic PWV recovered to pre‐swimming levels by 60 min after swimming in 25°C water, but baPWV was higher even at 60 min after swimming. PWVs did not change in the CON and S30 trials. Systemic vascular resistance based on Doppler ultrasonography did not change, but forearm vascular resistance based on strain‐gauge plethysmography was higher 30 and 60 min after swimming in 25°C water. Heart rate was higher, but stroke volume was lower 30 min after swimming in 25°C water, resulting in no detectable change in cardiac output. In conclusion, arterial stiffness increases acutely after moderate‐intensity swimming in cooler water.
