Abstract

This study aimed to determine whether arm-cranking training with electrical muscle stimulation (EMS) results in a greater improvement in vessel function than performing the same exercise without EMS. First, nine healthy young men performed two 20-min arm-cranking trials at 50% V˙O2max with and without EMS applied to the lower limbs. The flow-mediated vasodilation (FMD) of the right brachial artery was measured using a high-resolution ultrasound device. Both FMD and normalized FMD were increased significantly after the arm-cranking with EMS trial, and significant differences were observed between the two trials. Second, 16 healthy adult men were randomly assigned to either the arm-cranking exercise training (A) group or arm-cranking training with EMS (A+EMS) group. The subjects were engaged in 20 min of arm-cranking at 50% V˙O2max twice a week for 8 weeks with/without EMS applied to the lower limbs. The FMD increased significantly after A+EMS training session and the FMD in A+EMS group was significantly higher than that in the A group. These results indicate that acute/chronic endurance arm-cranking with EMS applied to the lower limbs improves the brachial artery endothelial function more markedly than the same exercise without EMS.
