Meta-analyses showed that when eccentric exercise was performed at higher intensities compared with concentric training, total and eccentric strength increased significantly. However, compared with concentric training, strength gains after eccentric training appeared more specific in terms of velocity and mode of contraction.

Eccentric training performed at high intensities was shown to be more effective in promoting increases in muscle mass measured as muscle girth. In addition, eccentric training also showed a trend towards increased muscle cross-sectional area.
