FIGURE 5.
Partial correlation of the left- and right-hand in bimanual handgrip force controlling for unimanual handgrip force. Partial correlation coefficients were used to determine the relationship between post-test bimanual left (BL) and right (BR) handgrip force normalized by the pre-test by controlling for unimanual left (UL) or right (UR) handgrip force in the left-hand and right-hand fatigue conditions, respectively. Data are plotted as residuals of each variable adjusted by control variable. The linear line indicates least squares regression.
