The most effective physiologic mean to prevent sarcopenia and related muscle malfunction is a physically active lifestyle, or\r\neven better, physical exercise. However, due to time constraints, lack of motivation, or physical limitations, a large number of\r\nelderly subjects are either unwilling or unable to perform conventional workouts. In this context, two new exercise technologies,\r\nwhole-body vibration (WBV) and whole-body electromyostimulation (WB-EMS), may exhibit a save, autonomous, and efficient\r\nalternative to increase or maintain muscle mass and function. Regarding WB-EMS, the few recent studies indeed demonstrated\r\nhighly relevant effects of this technology on muscle mass, strength, and power parameters at least in the elderly, with equal or\r\neven higher effects compared with conventional resistance exercise. On the contrary, although the majority of studies with elderly\r\nsubjects confirmed the positive effect of WBV on strength and power parameters, a corresponding relevant effect on muscle mass\r\nwas not reported. However, well-designed studies with adequate statistical power should focus more intensely on this issue.
