Feasibility of Lower-Body EMS Combined With Resistance Training in Postmenopausal Women: A Pilot Randomized Controlled Trial

Sponsor: Seoul National University

Summary

This pilot randomized controlled trial evaluates whether combining lower-body electrical muscle stimulation (EMS) with resistance training is feasible and beneficial for physically inactive postmenopausal women, who experience concurrent declines in muscle strength, body composition, arterial elasticity, and cardiac autonomic balance. Sixteen physically inactive postmenopausal women aged 50-70 years are randomly assigned (1:1) to either (A) supervised resistance training combined with lower-body EMS (applied to 6 muscle groups: lower back, lower abdomen, glutes, quadriceps, hamstrings, and calves) or (B) supervised resistance training alone. Both groups complete twelve 50-minute sessions (consisting of a 10-minute warm-up, 30-minute main exercise, and a 10-minute cool-down) over 6 weeks (twice weekly). Assessments before and after the intervention include body composition, lower-body muscle function, arterial stiffness, and 5-minute heart rate variability. The primary aim is to determine the feasibility of the protocol(recruitment, retention, session attendance, and intervention dose delivery) to inform a future definitive trial. Preliminary estimates of intervention effects on the measured outcomes are reported as secondary aims.
