The unique aspect of whole-body electromyostimulation its simultaneous but regionally dedicated stimulation of all main muscle groups with, when desired, supra-maximal intensity. This however can entail severe risks for health subsumable under the term "rhabdomyolysis". The aim was to examine the effect of different WB-EMS protocols on muscular strain as determined by creatine kinase (CK) kinetics to derive recommendations for WB-EMS application. Nineteen exercising men (28 +/- 5 years) without WB-EMS experience were randomly assigned to the WB-EMS protocols (bipolar, pulse width 350 mu s, rectangular) endurance training (a) without (b) with low-moderately intensive continuous WB-EMS with 7 Hz or (c) 85 Hz or slight (resistance) exercises (d) without/(e) with high intensity, intermittent (4s-4s) pulse intensity (85 Hz). CK was determined before/after testing and 24, 48 and 72 h post exercise. All endurance protocols resulted in a low increase of the CK concentration (2.5-3 fold of the pre-test level). No significant differences were observed between the groups without and with WB-EMS application or with high and low frequency (i. e. 7 vs. 85 Hz) WB-EMS. In contrast, the resistance type WB-EMS method generated up to a 48-fold increase of the pre-test level. Exercises without W-BEMS did not influence the CK concentration. As expected, there were significant differences in CK kinetics between endurance- and resistance-oriented WB-EMS protocols, primarily due to the different impulse intensity. These results should be taken into account in recommendations on regeneration and training frequency of different WB-EMS protocols
