Contraction

In a business cycle, the time between the peak and the bottom. That is, a contraction occurs between the end of economic growth and the end of the subsequent recession. Contractions are characterized by layoffs, a decline in GDP, and other negative factors. However, historically, contractions have tended not to last as long as expansions.

Generally, DOMS occurs in skeletal muscle after strenuous exercise, especially in case of intense eccentric contractions (Croisier et al.
Unaccustomed eccentric contractions may produce exercise-induced muscle damage, which is typically manifested as reduced maximal isometric strength and range of motion (ROM), as well as increased muscle soreness (Lavender and Nosaka, 2008; Warren et al.
It is well documented that repeated eccentric contractions or unaccustomed resistance training will cause muscle soreness, transient decrements in muscle function and an increased leakage of intracellular proteins into the vascular space (Clarkson and Hubal 2002; Howatson and van Someren, 2008; Smith, 1991).
