The objective of this study was to determine the effect of supplementation with isolated whey protein and a combined protocol of WB-EMS and whey protein, taking into account sarcopenic obesity and cardiometabolic appearance in men 70 years of age or older with sarcopenic obesity.


A randomized controlled trial was conducted with 100 randomly selected men aged 70 or older with sarcopenic obesity. The 100 men were divided into 3 groups:

  1.  WB-EMS and protein supplement (n=33).
  2.  Protein supplement (n=33).
  3.  Control group (n=34).


The WB-EMS protocol that was applied in this study was 85 Hz frequency, 350 us of pulse width in standing position with a duty cycle of 4 seconds of electrical impulse and 4 seconds of rest. 20 minutes of session were held each week for 16 weeks.


Body fat significantly decreased the WB-EMS group with protein supplementation and not so significantly in the protein supplementation group. In the control group body fat increased not so significantly. The area of ​​total visceral fat did not change in the control group and decreased in the WB-EMS groups with protein supplementation and in the protein supplementation only group. Again, a significant difference was determined between the WB-EMS group with protein supplementation and the control group.

The ratio of total cholesterol to HDL cholesterol changed favorably in both treatment groups and remained in the control group.


WB-EMS, time-friendly, efficient and highly personalized technology that mitigates barriers and concerns about conventional resistance exercise can be a safe and reasonable option for older, functionally limited and fragile people to fight obesity and sarcopenia.
