Eccentric contractions are a type of muscle contraction in which the muscle-tendon complex lengthens and contracts at the same time. This type of contraction has several distinct traits distinguishing it from other contractions, potentially resulting in unique adaptations.
Put simply, eccentric contraction happens whenever you activate a muscle to resist, smooth out and control a movement happening in the opposite direction. For example, when you use your flexors to control an extension, and vice versa.
An eccentric (lengthening) muscle contraction occurs when a force applied to the muscle exceeds the momentary force produced by the muscle itself, resulting in the forced lengthening of the muscle-tendon system while contracting (Lindstedt et al., 2001).
An eccentric (lengthening) muscle contraction occurs when a force applied to the muscle exceeds the momentary force produced by the muscle itself, resulting in the forced lengthening of the muscle-tendon system while contracting (Lindstedt et al., 2001).
Eccentric Contractions. An eccentric contraction results in the elongation of a muscle while the muscle is still generating force; in effect, resistance is greater than force generated. Eccentric contractions can be both voluntary and involuntary.
Eccentric contractions refer to muscle actions that occur when the external force applied to the muscle exceeds the force produced by the muscle itself, resulting in a lengthening action (i.e. when work is done on the muscle) (7, 8).
There are four types of striated muscle contractions: isometric, isotonic, concentric, and eccentric (see Figure. Muscle Contraction Categories). Isometric striated muscle contraction is characterized by a change in muscle tension without a change in muscle length.
Eccentric contractions, characterized by the lengthening of the muscle-tendon complex, present several unique features compared with other types of contractions, which may lead to unique adaptations.

An eccentric muscle contraction is characterized by the production of muscle force associated to a lengthening of the muscle-tendon system. This muscle solicitation can cause micro lesions followed by a regeneration process of the muscle-tendon system.
