Acute and delayed influences of eccentric and stretch-shortening cycle exercices. Eccentric- and stretch-shortening cycle (SSC) type exercises are of great functional interest for human locomotion. However, the repetition of such types of muscle actions during prolonged exercises or at high intensities may induce acute and delayed structuro-functional deficits, frequently associated with delayed onset muscle soreness (DOMS). These alterations are reversible owing to the intervention of an inflammatory process. The associated biochemical, thermal and mechanical changes are suggested to sensitize small diameter muscles afferents (type III and IV) that may then contribute to the DOMS generation and neural adjustments to the contractile failure. © 2010 ACAPS, EDP Sciences.
