摘　　要：研究静力性拉伸对人体动脉血管硬度的急性作用,并比较3种不同拉伸方式的作用效果差异。39名高校健康学生(男性18名;女性21名)分3次分别完成3种急性静力性拉伸(单侧小腿拉伸、单侧大腿拉伸、双侧大腿交替拉伸),每次拉伸前和拉伸后即刻、15、30、45、60 min,测试心踝血管指数、血压、心率等指标。结果发现:3种静力性拉伸后心踝血管指数显著下降,男女左右侧的心踝血管指数在拉伸后即刻和15 min均低于拉伸前基值,单侧大腿拉伸与双侧交替大腿拉伸的心踝血管指数在拉伸后30、45 min仍低于拉伸前。3种拉伸方式作用效果存在显著差异,在拉伸后即刻与15 min,男性单侧大腿拉伸与双侧大腿拉伸的心踝血管指数低于单侧小腿拉伸,女性双侧大腿拉伸的心踝血管指数低于单侧小腿拉伸与单侧大腿拉伸。结论:对心血管系统负荷较小的静力性拉伸能够降低动脉硬度,效果表现为:双侧交替大腿拉伸>单侧大腿拉伸>单侧小腿拉伸,其中,双侧交替大腿拉伸降低动脉僵硬度的效果至少可维持45 min。To study the acute effect of static stretching on human arterial stiffness,compare the effects of three dif-ferent stretching modes on arterial stiffness.39 healthy young subjects(18 males and 21females)completed three acute static stretching in three separate sessions(unilateral calf stretching,unilateral thigh stretching,and bilateral thighs stretching alternately),and cardio-ankle vascular index(CAVI),blood pressure and heart rate of participants were measured before stretching and 0,15 min,30 min,45 min and 60 min after stretching.The results show that:(1)the CAVI decreased significantly after three kinds of static stretching,and CAVI of both left and right sides of male and female immediately after stretching and 15 min were lower than those before stretching,and the 30 min and 45 min of unilateral thigh stretching and bilateral alternating thigh stretching were still lower than those before stretching.(2)There were significant differences in effects of the 3 stretching methods,and at immediately and 15 min after stretching,the CAVI of unilateral and bilateral thigh stretching in males was lower than that of unilateral calf stretching,and CAVI of female bilateral thigh stretching was lower than that of unilateral calf stretching and unilateral thigh stretching.Conclusion:static stretching with low load of cardiovascular system can reduce arterial stiffness,and the effect is as follows:bilateral alternating thigh stretch>unilateral thigh stretch>unilateral calf stretching.Among them,the effect of bilateral alternate thigh stretching to reduce arterial stiffness can at least maintain 45 min.
