Abstract
Purpose: High Intensity (resistance exercise) Training (HIT) and Whole-Body Electromyostimulation (WB-EMS) may be the most promising approaches to generate favorable changes of body composition and strength with optimum time-efficiency. In this study, we compared the effect of WB-EMS on body composition and muscle strength with the “golden standard” HIT over 16 weeks. Methods: 30-50 year-old men (n=48) were randomly allocated to a HIT (n=24) with 2 sessions/week of a “single-set-to-failure- protocol” or a WB-EMS-group that exercised 3 sessions in two weeks, using intermittent stimulation (6 sec - 4 sec rest; 85 Hz, 350 ms) over 20 min. An Intention to treat analysis was calculated with Lean Body Mass (LBM) defined as primary endpoint, and appendicular skeletal muscle mass (ASMM), maximum dynamic leg-extensor and isometric back-extensor strength as secondary endpoints. ››Results: Net exercise time/session was 30.3 ±2.3 for HIT vs. 20 ±0 min for WB-EMS (p<.001). LBM (HIT: 1.24 ±1.40% vs. WB-EMS: 0.91 ±1.12%) and ASMM (1.92 ±1.51% vs. WB-EMS: 1.52 ±1.48%) significantly increased (p≤.003), with no significant group differences (LBM: p=.406 and ASMM: p=.341). In parallel, changes of maximum dynamic leg strength (HIT: 13.5 ±13.9%, p=.001 vs. WBEMS: 8.0 ±10.2%, p=.008) and maximum isometric back strength (10.4 ±9.0%, p<.001 vs. 11.7 ±9.9%; p<.001) were comparable (p=.332 and p=.609) between groups. Discussion: In conclusion, compared to HIT, WB-EMS can be considered as an even more time-efficient but pricey option for subjects who aim to improve their body composition and general strength.
