  1. MVC, maximal voluntary isometric knee extension joint torque; MT, Muscle thickness of vastus lateralis; ST, subcutaneous tissue thickness; ME, modified entropy of surface electromyography at 65% of the maximal voluntary contraction; RMS, root mean square value of surface electromyography for all channels in electrode grid at 65% of the maximal voluntary contraction; NRMS, root mean square of surface electromyography for all channels in electrode grid at 65% of the maximal voluntary contraction normalized by that at 20% of the maximal voluntary contraction; CRR, correlation coefficient value in root mean square of surface electromyography between 20 and 65% of the maximal voluntary contraction
  2. * indicates significant correlation
