Abstract: Endurance exercises, such as cycling or running, are useful for reducing arterial stiffness. However, individuals with a low physical fitness level, or patients suffering from leg diseases with pain, are unable to perform such moderate-intensity lower-limb exercises for long periods of time. The aim of this study was to evaluate the effects of acute cycling with Electrical muscle stimulation (EMS) on the brachial to ankle pulse wave velocity (ba-PWV). Ten healthy adult men performed 3 sessions, as follows of 20 min: cycling at 50% VO2max (C), cycling at an intensity of 50%VO2max subtracted from VO2 during EMS (LC), and cycling at the intensity of the LC trial while also being combined with EMS (LC+E). The ba-PWV was measured before and after each exercise. In addition, the femoral artery blood flow (BF) was measured in eight healthy adult men before and after exercise using an ultrasound imaging system. In the C and LC+E trials, the ba-PWV significantly decreased immediately after the exercise session, whereas the ba-PWV did not significantly change following the LC trial in any session. Compared with the baseline, the femoral artery BF values significantly increased after all trials. In the C and LC+E trials, the femoral artery BF was significantly greater than that in the LC trial. Acute endurance low-intensity cycling with EMS results in a reduction in the arterial stiffness which is similar to that with moderate-intensity exercise.
