  2. Muscle contraction - Wikipedia

    en.wikipedia.org/wiki/Muscle_contraction

    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 ...

  3. Isotonic contraction - Wikipedia

    en.wikipedia.org/wiki/Isotonic_contraction

    A near isotonic contraction is known as Auxotonic contraction. 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.

    For example, the triceps brachii contracts, producing a shortening (concentric) contraction, during the up phase of a push-up (elbow extension). During the down phase of a push-up, the same triceps brachii actively controls elbow flexion while producing a lengthening (eccentric) contraction. It is still the agonist, because while resisting ...

    en.wikipedia.org/wiki/Concentric_objects

    The region of the plane between two concentric circles is an annulus, and analogously the region of space between two concentric spheres is a spherical shell. [6] For a given point c in the plane, the set of all circles having c as their center forms a pencil of circles. Each two circles in the pencil are concentric, and have different radii.

  6. Hill's muscle model - Wikipedia

    en.wikipedia.org/wiki/Hill's_muscle_model

    During isometric contractions the series elastic component is under tension and therefore is stretched a finite amount. Because the overall length of the muscle is kept constant, the stretching of the series element can only occur if there is an equal shortening of the contractile element itself.

    Strength coach Jeff Cavaliere demonstrates a simple way to tell if you're lifting too heavy so you can avoid injury and ensure you're building strength safely.

    Eccentric, concentric, and isometric phases are all distinct parts of most exercises you do in your workouts. Here's what they mean and how to use them. Eccentric, concentric, and isometric phases ...

  9. Eccentric training - Wikipedia

    en.wikipedia.org/wiki/Eccentric_training

    A study was performed to test how eccentric and concentric contractions affect cardiac autonomic modulation after exercise. Men (aged 18–30) were divided into four groups: concentric control, eccentric control, concentric training, and eccentric training. Results concluded that resistance training (eccentric contractions) promoted strength gain.
