Short time effect of a single session of intense whole-body electromyostimulation on energy expenditure. A contribution to fat reduction?

To determine the underlying mechanisms after 1 session of (intense) whole-body electromyostimulation (WB-EMS) on total energy expenditure (TEE) and resting metabolic rate (RMR), 16 subjects followed a standardized protocol of indirect calorimetry for up to 72 h in 12-h intervals. The single session significantly increased RMR by approximately 25% ± 10% (p < 0.001) and TEE by approximately 9.5% ± 1%, a net effect of ∼460 ± 50 kcal (WB-EMS vs. control group).
