Muscles are stronger in eccentric contractions than in isometric and concentric contractions. Following eccentric action, muscle force is increased—a phenomenon referred to as residual force enhancement (RFE).

Why is eccentric better than concentric?

Higher muscular forces can be produced during eccentric contractions compared with concentric. Eccentric contractions produce less fatigue and are more efficient at metabolic level compared with concentric contractions. Unaccustomed eccentric contractions produce transient muscle damage, soreness and force impairments.

Which muscle contraction is strongest?

The eccentric contraction is the strongest type of contraction your body is capable of producing while actively moving. Studies indicate that as much as 20% more force can be generated during an eccentric contraction when compared to a concentric contraction.
