In a peer-reviewed study published in Physical Therapy Research (2022), 12 healthy men completed 1 hour of prolonged sitting. One session included 20 minutes of lower-body EMS using belt electrodes at 4 Hz and 50% maximum intensity.

In the control trial, vascular endothelial function declined, with FMD dropping significantly. In the EMS trial, normalised flow-mediated dilation (nFMD) of the brachial artery rose significantly from 0.84 ± 0.43 to 1.14 ± 0.77.

Researchers from Osaka Yukioka College and Tokushima University showed passive muscle contractions increase blood flow, shear stress and nitric oxide while reducing sympathetic activity.

This credible evidence proves EMS supports better circulation during sitting. Read the full post for practical desk-worker insights and mechanisms.
