“…Because the purpose of our study was to determine the ability of the NMES to influence the concentration of HbA 1C , lipid profiles, and hemodynamic parameters in T2DM patients, we used 35-Hz NMES eliciting incomplete, tetanic contractions of the muscles. NMES frequencies between 10 and 50 Hz (eliciting tetanic contractions) proved effective in our earlier study [ 26 ] and in the randomized clinical trials with patients with chronic cardiac deficiency conducted by other authors [ 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. The authors of the studies who applied NMES for 3–12 weeks reported that it improved participants’ exercise capacity [ 26 , 28 , 29 , 30 , 31 , 32 , 34 , 36 , 37 ], metabolic and hemodynamic parameters, including peak VO 2 [ 28 , 29 , 30 , 31 , 34 , 37 ], as well as reducing their diastolic blood pressure [ 29 ], and increasing LVEF (%) [ 26 ].…”
