When properly matched for load/intensity, performing eccentric or concentric contractions results in similar levels of overall muscle growth. However, this study shows that the *type* of muscle growth is different between the two: eccentric-only training mainly increases muscle fiber length whereas concentric-only training mainly increases muscle fiber diameter. Therefore, the specificity of training gains is even dependent on contraction type. Including eccentric overloads and concentric-only exercises (like sled drags) is necessary for optimal development and aesthetics.
