Handgrip exercise elevates basilic venous hemodynamic parameters in healthy subjects

PurposeThis study examined the effect of handgrip exercise on hemodynamic indices to determine the most effective regimen for promoting blood circulation.MethodsHealthy individuals were divided into three treatment groups with each performing exercises using an electronic handgrip. Groups performed exercises to determine the most appropriate tap position, frequency, and duration. The hemodynamic indices were measured by Doppler ultrasound.ResultsThe best handgrip position was the weak tap position. Venous blood flow velocity and blood flow increased significantly with each exercise relative to the resting state (p < 0.01). Venous blood flow velocity and blood flow peaked with handgrip exercise frequency of 25 times/min for 2 min (p < 0.01). No significant differences were observed between sexes.ConclusionHandgrip exercise is an effective method for improving blood circulation in the upper extremities.
