To slow down the joints against body weight and gravitational forces, we need eccentric strength! Eccentric contractions occur when a muscle lengthens while under tension, such as when lowering a weight or controlling a movement's descent. Eccentric strength helps stabilize joints and control movements, reducing the risk of injuries during activities like running, jumping, and lifting. Eccentric exercises are commonly used in physical therapy to rehabilitate injuries, as they can help rebuild muscle strength and control while minimizing stress on injured tissues. Eccentric muscle actions can store and release energy more efficiently than concentric contractions, contributing to better overall movement efficiency and endurance. Many daily activities and sports involve eccentric muscle actions, like walking downstairs or decelerating during a sprint.
