EMS training device, and method for protecting an EMS training device

An electric muscle stimulation (EMS) training device for subjecting muscles in a living body to electric stimuli by EMS, the EMS training device comprising:

• an EMS stimulation generating unit which forms from a current drawn from a current source a plurality of EMS stimuli which follows a predetermined stimulation diagram and is distributed in respect of time and electrodes, and which consist of current pulses and/or alternating-current with predetermined values including a predetermined amplitude and frequency pattern;
• EMS electrodes attachable to a living body for applying the stimuli to the living body;
• line branches, wherein each line branch connects one of the EMS electrodes in an electrically conductive manner to the EMS stimulus generating unit to apply the EMS electrode with EMS stimuli associated with the EMS electrode to permit current with the predetermined amplitude and frequency pattern to be conducted through the living body;
• at least one measuring device configured to detect in one of the line branches a resistance or a quantity corresponding to the resistance as an actual value for corrosion protection of the EMS electrode and/or other elements susceptible thereto of the at least one of the line branches;
• at least one comparison device configured to compare the actual value in the one line branch with a stored or determined target value;
• and
• at least one compensation device configured to compensate a deviation of the actual value from the target value in the one line branch,
• wherein the EMS electrodes are pairwise associated with each other to permit the current with the predetermined amplitude and frequency pattern to be conducted through the living body in a number of current circuits respectively comprising two of the line branches, which circuits respectively comprise an associated pair of EMS electrodes.
