The "sliding filament theory" [23] has been a dogmatic explanation for muscle contraction, but it has difficulties in accurately predicting the force and energy efficiency of eccentric contractions. Several theories have been put forth to explain the mechanism of eccentric contractions.

Most HHDs measure the isometric type of contraction, and isokinetic dynamometers can test the strength of both concentric and eccentric contractions. Concentric contractions cause muscle shortening, while eccentric contractions cause muscle lengthening.
Every lift consists of a concentric contraction and an eccentric contraction.
Al, 1986, applied eccentric contraction to the leg flexors to young and elderly women and determined their CK levels.
Studies (6,14,20,21,24,27) have shown that eccentrically biased acute exercise of high eccentric contraction component results in ultrastructural muscle injury.
Eccentric contraction is commonly used during training programs to improve muscular power for the quadriceps muscles [1].
The major muscular contraction involved in active stretches is the eccentric contraction. In this contraction, the muscle develops tension while the overall length of the muscle increases by stretching under tension.
As a result, there is more stress on the shorter sarcomeres during an eccentric contraction causing them to elongate relatively further than the longer sarcomeres (3).
Optimal function of the lower limb during weight bearing and closed chain activities requires both concentric and eccentric contraction of the involved muscles in order to minimize ground reaction forces imposed on the ankle-foot complex [6,11].
Stretch-shortening cycle (SSC) exercise is defined as the eccentric contraction of an active muscle immediately followed by a concentric contraction (Komi, 1984).
