Abstract

The effect of whole body-electromyostimulation in community-dwelling women >= 70 with sarcopenic obesity was heterogeneous, with high effects on muscle mass, moderate effects on functional parameters, and minor effects on fat mass. Further, we failed to determine a supportive effect of additional protein-enriched dietary supplementation in this albeit predominately well-nourished group.Introduction The aim of the study was to determine the effect of whole-body electromyostimulation (WB-EMS) on sarcopenic obesity (SO) in community-dwelling women more than 70 years with sarcopenic obesity.Methods Seventy-five community-dwelling women >= 70 years with SO were randomly allocated to either a WB-EMS application with (WB-EMS & P; 24.9 +/- 1.9 kg/m(2)) or without (WB-EMS; 25.2 +/- 1.8 kg/m(2)) dietary supplementation (150 kcal/day, 56 % protein) or a non-training control group (CG; 24.7 +/- 1.4 kg/m(2)). WB-EMS consisted of one weekly session of 20 min (85 Hz, 350 mu s, 4 s of strain-4 s of rest) performed with moderate to high intensity. Primary study endpoint was the Sarcopenia Z-Score constituted by skeletal muscle mass index (SMI, as assessed by dual energy X-ray absorptiometry), grip strength, and gait speed, and secondary study endpoint was body fat (%).Results Sarcopenia Z-score comparably increases in the WB-EMS and the WB-EMS&P-group (p=.046). Both groups differ significantly (p=.001) from the CG which deteriorated significantly (p=.006). Although body fat changes were most pronounced in the WB-EMS (-0.9 +/- 2.1; p=.125) and WB-EMS&P (-1.4 +/- 2.5; p=.028), reductions did not statistically differ (p=.746) from the CG (-0.8 +/- 2.7; p=.179). Looking behind the covariates, the most prominent changes were determined for SMI, with a significant increase in both EMS-groups (2.0-2.5 %; p=.003) and a decrease in the CG (-1.2 +/- 3.1 %; p=.050) with significant between-group differences (p=.001).Conclusion WB-EMS is a safe and attractive method for increasing muscle mass and functional capacity in this cohort of women 70+ with SO; however, the effect on body fat is minor. Protein-enriched supplements did not increase effects of WB-EMS alone.
