Eccentric contractions are known to produce more force compared to isometric and concentric contractions. This is primarily because during eccentric contractions, the muscle fibers lengthen while generating tension, which allows for a greater number of cross-bridge formations between actin and myosin filaments. This mechanical advantage means that the muscle can handle heavier loads when it is lengthening under tension.

In practical terms, when a muscle is activated to resist an external force while being elongated, it efficiently utilizes its structural properties, becoming more robust to heavy weights. This phenomenon is often noted in activities like lowering a weight: the muscle can control the descent more effectively than it can lift the same weight upward.

In contrast, isometric contractions occur without any change in muscle length and can maintain tension, but the force generated is typically less than that seen in eccentric contractions. Concentric contractions involve shortening of the muscle while it creates force, resulting in a power output that is lower than in eccentric contractions due to the energy demands of overcoming resistance while shortening. The label "static" could be seen as synonymous with isometric; however, it also lacks the context of tension being produced during lengthening, which is central to understanding the efficacy of eccentric contractions.
