Effect of Whole Body Electromyostimulation and/or Protein Supplementation on Sarcopenic Obesity in 70+

The aim of the study is to determine the effect of 16 weeks of Whole Body-Electromyostimulation (WB-EMS) and/or protein supplementation on Sarcopenic Obesity (SO) in community dwelling male subjects 70+ with SO . 108 eligible men will be randomly assigned to either a (1) WB-EMS and Protein (2) Protein (3) sedentary control group. WB-EMS will be applied 1,5 x 20 min per week (i.e. 3 sessions in two weeks) with bipolar current, 85 Hz in an intermitted mode (4 s - 4 s of rest). Protein supplementation will be adjusted to dietary intake in order to reach a total protein intake between 1,5 - 1,7g/kg body-mass/d . Primary study endpoint will be the Sarcopenia Z-Score
