Values are expressed as means±SD.
*p<0.05, significantly different from pre. †p<0.05, significantly different from COOL. MVC torque, maximal voluntary contraction torque; RMSMAX, M-wave and RMSMAX/M-wave represent the average of root mean square, maximal M-waves and normalised electromyogram activities of vastus lateralis and rectus femoris muscles; Peak RTD, peak rate of torque development.
