摘　　要：目的探讨不同方式踝关节运动对健康成年人股静脉血流动力学及下肢疲劳程度的影响。方法采用便利抽样法选取2021年1—6月南京医科大学第一附属医院符合入组条件的30名健康成年人为研究对象。采用前瞻性自身前后对照方法,先使用多普勒超声探讨静息状态、踝关节背屈和跖屈动作对下肢股静脉血流的影响。再让受试者接受两种踝关节运动,传统方式为背屈10 s放松5 s、跖屈10 s放松5 s;改良方式为背屈1 s放松1 s、跖屈1 s放松1 s。分别在运动5 min后即刻、运动结束休息5 min、运动结束休息10 min时对受试者股静脉血流动力学进行测定,并评估运动持续1、3、5 min时受试者的主观感觉疲劳程度。结果与静息状态相比,踝关节背屈和跖屈的股静脉血流峰速、平均流速、血流量均增加(P<0.01);与跖屈相比,踝关节背屈时的股静脉血流峰速、平均流速、血流量提高(P<0.05)。不同时间点两种踝关节运动方式的股静脉血流峰速和平均流速比较,差异无统计学意义(P>0.05)。两种运动持续1、3 min时受试者的主观感觉疲劳程度得分比较,差异无统计学意义(P>0.05),但以传统方式持续运动5 min后受试者的主观感觉疲劳程度得分高于改良方式(P<0.05)。结论健康成年人踝关节背屈和跖屈对股静脉血流速度影响的作用时间为1~2 s;单位时间内踝泵运动的背屈和跖屈节律建议为1 s,其较传统方式更简单易行;医护人员可指导患者提高每日踝泵运动的次数,每次运动5 min或在患者耐受范围内。Objective To explore the effects of different ankle pump exercises on femoral vein hemodynamics and lower limb fatigue in healthy adults.Methods From January to June 2021,30 healthy adults who met the enrollment conditions in the First Affiliated Hospital with Nanjing Medical University were selected by convenient sampling as the research subject.Using a prospective self-contrast method,the effects of resting state,ankle dorsiflexion and plantar flexion on femoral vein blood flow in lower limbs were investigated by Doppler ultrasound.Then the subjects received two kinds of ankle exercises,the traditional method was dorsiflexion 10 s relaxation 5 s,plantar flexion 10 s relaxation 5 s;the modified method was dorsiflexion 1 s relaxation 1 s,plantar flexion 1 s relaxation 1 s.The hemodynamics of subjects were measured immediately after 5 min of exercise,5 min of rest after exercise and 10 min of rest after exercise.And the subjective sensory fatigue scores of the subjects for different exercise modes were evaluated when the exercise lasts for 1,3 and 5 minutes.Results Compared with the rest state,the peak velocity,average flow velocity and blood flow of femoral vein in ankle dorsiflexion and plantar flexion were increased,and the differences were statistically significant(P<0.01).Compared with plantar flexion,the peak velocity,average flow velocity and blood flow of femoral vein during ankle dorsiflexion were statistically increased(P<0.05).There was no statistical difference in peak velocity and average velocity of femoral vein blood flow between the two ankle pump exercises at different time points(P>0.05).There was no statistical difference in the scores of subjective sensory fatigue after 1 and 3 min of two kinds of exercise(P>0.05),but the scores of subjective sensory fatigue after 5 min of traditional exercise were higher than those of modified exercise with a statistical difference(P<0.05).Conclusions The effect time of ankle dorsiflexion and plantar flexion on femoral vein blood flow velocity in healthy adult
