Mean and maximum values of the normalized surface electromyographic (EMG) envelope of the biceps femoris and medial gastrocnemius. a The mean EMG values of the BF; b the maximum EMG values of the BF; c the mean EMG values of the MG; d the maximum EMG values of the MG. ○ represents an outlier. * indicates a statistical difference (P < 0.05). × denotes the mean of the box values. FTP: functional threshold power; GTH: greater trochanter height; MVC: maximum voluntary contraction; RF: rectus femoris; TA: tibialis anterior; BF: biceps femoris; MG: medial gastrocnemius
