Abstract:
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 adults is 1 to 2 seconds. The rhythms of dorsiflexion and plantar flexion of ankle pump exercise in unit time are suggested to be 1 s, which is simpler and easier than the traditional exercise. We should instruct the patient to increase the number of ankle pump exercises every day for 5 minutes or within the patient's tolerance.
