Several studies have shown that WB-EMS has favorable effects in terms of body composition. Also, with respect to abdominal body fat central predictor of metabolic and coronary diseases, it was impressive how WB-EMS rapidly and significantly decreases this risk factor.
The purpose of this study was to determine the effect of WB-EMS with low intensity exercises if it produces a significant increase in energy expenditure.
19 healthy young men were assigned for this study. The pre-test protocol was to maintain your usual lifestyle and nutrition and not exercise 48 hours before the test. The 19 subjects performed two tests one without WB-EMS and one with WB-EMS.
The WB-EMS protocol was intermittently using a frequency of 85 Hz with a duty cycle of 4 seconds and 4 seconds of rest at the maximum tolerance limit of the subjects. A low session duration and low load training strategy was applied.
The energy expenditure was 17% higher during the year with the application of WB-EMS compared to the group without WB-EMS. The intensity measurement during exercise was higher with WB-EMS than without WB-EMS using the Borg scale.
Although the study determined a significant effect of WB-EMS during the exercise of low intensity dynamic resistance in energy expenditure. The results were not as expected as a greater energy expenditure (three times greater) was expected. The reason for this may be due to the inability of indirect calorimetry to properly assess energy expenditure.
