In concentric contraction, muscle tension is sufficient to overcome the load, and the muscle shortens as it contracts. [8] This occurs when the force generated by the muscle exceeds the load opposing its contraction. During a concentric contraction, a muscle is stimulated to contract according to the sliding filament theory. This occurs ...
When the load exceeds the force that can be developed by the muscle at a constant length, as in an eccentric muscle action, the exercise is referred to as involving negative work, because the muscle is absorbing energy. [1] Eccentric contractions use less metabolic energy, even though they can create more force than concentric actions. [1]
“The muscle is lengthening. In an eccentric movement, the force of the contraction is less than the force giving upon it, so the muscle can lengthen at an appropriate time,” says Guillermo ...
There are two types of isotonic contractions: (1) concentric and (2) eccentric. In a concentric contraction, the muscle tension rises to meet the resistance, then remains the same as the muscle shortens. In eccentric, the muscle lengthens due to the resistance being greater than the force the muscle is producing. [citation needed]
A stretch-shortening cycle (SSC) is an active stretch (eccentric contraction) of a muscle followed by an immediate shortening (concentric contraction) of that same muscle. Research studies [ edit ]

The speed of the switching is extremely fast, 0.20 seconds or less. For example, high-level sprinters execute the switch from the eccentric contraction that occurs when the foot hits the ground to the concentric contraction when the foot breaks contact with the ground in less than 0.10 seconds.
The isoinertial's muscle activity follows the muscular action of the sporting gesture or rather what the body or parts of it are in duty to perform in sports, according to which, in strength and speed variable, an inertial load (such as a ball), a limb or the body itself (such as when accelerating or changing direction) the athlete is forced to respond at the level coordinative motor and ...
