补充L-瓜氨酸可以减轻局部寒冷刺激对血压和脉搏波反射(增强指数)的影响,但对全身冷刺激和同时进行运动时的心血管保护作用尚不清楚。该研究假设L-瓜氨酸可以减轻冷刺激和等长握拳收缩(isometric handgrip,IHG)运动对血压和增强指数的影响。方法:选取自愿参加该研究的健康男性16名,年龄(23±3)岁。实验室温度4℃。应用平面压力波测定测量桡动脉脉搏波,取两次测量平均值。5min静息仰卧位
Supplementing with L-citrulline can reduce the effects of local cold stimulation on blood pressure and pulse wave reflex (enhanced index), but its cardiovascular protective effect on systemic cold stimulation and concurrent exercise is unclear. This study hypothesized that L-citrulline may reduce the effects of cold stimulation and isometric handgrip (IHG) exercise on blood pressure and enhancement index. Methods: Sixteen healthy volunteers who volunteered to participate in the study were selected and were aged 23 ± 3 years. Laboratory temperature 4 ℃. Radial artery pulse wave measurement using planar pressure wave measurement, take two measurements average. 5min resting supine position
