摘要
目的:观察单次热水足浴对健康青年动脉硬度的短时影响。方法:应用均衡随机交叉自身对照设计,8名健康青年随机进入对照日和足浴日实验,均分别于三个时间点,即0 min、30 min和50 min重复测量其心-踝血管指数(CAVI),其中对照日实验中对受试者不进行任何干预,而足浴日实验中在0 min和30 min之间进行足浴,足浴的水温为42~45℃、持续30 min,7 d后每位受试者实验内容进行交叉。结果:对照日的三个时间点上,受试者的CAVI基本保持不变,分别为(6.3±0.9)、(6.3±0.8)和(6.5±0.8)。而足浴日中,CAVI基础值从(6.1±0.4)下降到30 min时的(5.4±0.5),P<0.01,和50 min的(5.7±0.4),P<0.05,差异具有显著性,30 min的CAVI显著低于对照日的30 min CAVI(P<0.05);而鼓膜温度在足浴后即刻也明显短暂升高。结论:单次足浴可使人体动脉硬度短时下降,这可能与核心体温的升高有关。
Objective:To observe immediate effects of a single hot footbath on arterial stiffness in human.Methods:With a counterbalanced,randomized crossover own control design,eight healthy young humans randomly entered trials of control or footbath days.Cardio-ankle vascular index(CAVI) was measured in the eight healthy young humans at 0 min(baseline),30 min and 50 min.Subjects in control trial received no intervention while those in footbath trial underwent footbath at 42~45℃ for 30 min.After seven days,trial extent of each subject was crossed.Results:At the three time points in control trial,CAVI of the subjects were(6.3±0.9),(6.3±0.8) and(6.5±0.8) respectively,which kept constant on the whole.But in footbath trial,baseline CAVI(6.1±0.4) decreased to(5.4±0.5),P〈0.01,at 30 min and(5.7±0.4),P〈0.05,at 50 min,and there existed significant difference on CAVI at 30 min compared with that of control day(P〈0.05).Tympanic temperature also significantly increased immediately after footbath.Conclusion:A single footbath could improve arterial stiffness in human for a short period,and it may be associated with elevated core temperature.
