Is the cross-over effect of a unilateral high-intensity leg extension influenced by the sex of the participants?

Table 2 Mean (and standard error of the mean) of the normalized maximal surface electromyographic root mean square (sEMG) expressed in percentage (%) values of the vastus lateralis, the vastus medialis, and the rectus femoris of the exercising limb and the non-exercising limb measured during the maximal voluntary contractions before (PRE) and after (POST) the 30-s unilateral exercise of the EL for both the females and males
