Ten meta-analyses were performed on the different outcomes of strength with a maximum of up to 11 studies per analysis. Studies were categorised depending on the mode of strength measures (total, eccentric, concentric, isometric), and then further divided based on how strength was measured (average peak torque or 1 RM). Subgroup analyses were performed according to: whether eccentric training intensity was higher or comparable with concentric training; and whether velocity of testing and training were matched or mismatched. Studies in which eccentric versus concentric training was performed at a higher intensity (MVC or submaximal) were allocated to the subgroup analyses of higher eccentric intensity. In contrast, studies that equated intensity of both types of training as a percentage of the concentric 1 RM were allocated into the subgroup of comparable training intensities. To determine whether gains in strength were velocity-specific, studies were allocated into subgroups that had matched or mismatchedvelocities of testing and training.
