Increase in appendicular muscle mass
Appendicular muscle mass increased in the medical EMS group (whole-body EMS/WB-EMS) and decreased in the control group (KG), with significant group difference (WB-EMS 0.5% ± 2.0% vs. KG -0.8% ± 2.0%, p = 0.025).
Decrease in abdominal fat mass
Abdominal fat mass decreased in the WB-EMS group and increased in the KG, with also significant difference between the two groups (WB-EMS -1.2 % ± 5.9 % vs. KG 2.4 % ± 5.8 %, p = 0.038).
Favourable development of thigh muscle mass
Muscle mass of the thighs showed more favourable values in the WB-EMS group than in the KG (WB-EMS 0.5 % ± 2.5 % vs. KG -0.9 % ± 1.9 %, p = 0.033). The effects on thigh fat mass were borderline non-significant (WB-EMS -0.8 % ± 3.5 % vs. KG 1.0 % ± 2.6 %, p = 0.050).
Improvement in leg extensor strength
The improvement in leg extensor strength was significantly higher in the WB-EMS group than in the KG group (WB-EMS 9.1 % ± 11.2 % vs. KG 1.0 % ± 8.1 %, p = 0.010).
Good acceptance & no side effects
WB-EMS was well accepted by the non-athletic women. There were no relevant injuries. Side effects were not reported
