    Abstract:
    The primary aim of the project was to determine the combined effect of whole-body electromyostimulation (WB-EMS) and protein supplements on local and overall muscle/fat distribution in older man with sarcopenic obesity (SO). Community-dwelling (cdw) men ≥ 70 years with SO were randomly allocated to a WB-EMS and protein supplementation (n = 33) or a non-intervention control group (CG: n = 34). WB-EMS was conducted 1.5 sessions of 20 min/week for 16 weeks. Whey protein supplementation aimed to ensure a daily intake of 1.8 g/kg body mass. The primary study endpoint was muscle/fat distribution of the total intra-fascial volume of the mid-thigh as determined by MRI. The core secondary endpoint was appendicular muscle mass (ASMM) and trunk fat; subordinate secondary endpoint was lower-leg performance. Thigh lean muscle volume increased significantly in the WB-EMS&P (p < 0.001) and increased slightly in the CG (p = 0.435). In parallel, fat volume increased significantly in the CG (p < 0.001) and was maintained in the WB-EMS&P group (p = 0.728). Group differences for both parameters were significant (p = 0.033 and p = 0.002). ASMM and trunk fat also differed significantly (p < 0.001) between WB-EMS and CG, with significant positive changes in the WB-EMS&P (p < 0.001) and no relevant changes in the CG (p ≥ 0.458). Finally, changes of gait velocity, leg-extensor strength, and advanced lower extremity function of the WB-EMS&P group differed significantly from the CG (p ≤ 0.002). WB-EMS combined with whey protein supplements favorably affects local and overall muscle/fat distribution and lower limb functioning in cdw men 70+ with SO. Thus, this time-saving, joint-friendly, and highly customizable approach may be an option for people either unable or unmotivated to conduct intense (resistance) exercise protocols.Trial registration number NCT02857660 on http://www.clinicaltrials.gov .
