eccentric strengthening
Pronunciation: ek-SEN-trik
Exercise technique where muscles lengthen while contracting, used therapeutically for tendon rehabilitation.
Full Definition
A specific form of muscle training where the muscle generates force while lengthening, contrasting with concentric (muscle shortening) and isometric (static) contractions. Eccentric exercises have gained prominence in sports medicine rehabilitation, particularly for tendinopathy treatment, as they promote collagen synthesis and tendon remodeling. Examples include negative calf raises for Achilles tendinopathy or slow lowering phases during squats. The controlled lengthening creates beneficial mechanical stress on healing tissues while improving strength and function. Eccentric training typically produces greater force generation and may cause more delayed-onset muscle soreness than other contraction types.
Usage
Usage note: Specify exercise parameters (load, repetitions, progression) when documenting rehabilitation protocols.
