Rulemaking processes are generally designed to ensure that. 1  The public is informed of proposed rules before they take effect; 2  The public can comment on the proposed rules and provide additional data to the agency; 3  The public can access the rulemaking record and analyze the data and analysis behind a proposed rule;
Concentric contractions: A concentric contraction is a type of muscle contraction where the length of the muscles shorten while undergoing tension. For example, when you pick up a curl bar and perform a biceps curl, the length of your biceps muscles shorten.Your hands start down by your sides, and ends with your hands up by your shoulders.nd it is these three different types of muscular tensions that are used to define the three different types of muscular âcontractionsâ. The three different types of muscular contractions, therefore, are: 1  Concentric contractions (shorten), 2  Eccentric contractions (lengthen). 3  Isometric contractions (remain the same).
Contractions that permit the muscle to shorten are referred to as concentric contractions. An example of a concentric contraction in the raising of a weight during a bicep curl. In concentric contractions, the force generated by the muscle is always less than the muscle's maximum (P o).As the load the muscle is required to lift decreases, contraction velocity increases.This occurs until the muscle finally reaches its maximum contraction velocity, V max. By performing a series of constant velocity shortening contractions, a force-velocity relationship can be determined.n concentric contractions, the force generated by the muscle is always less than the muscle's maximum (P o). As the load the muscle is required to lift decreases, contraction velocity increases.
