The execution of a countermovement prior to the main movement, during which the agonist muscles experience a stretch-shortening cycle (shortening after being lengthened) enhances the exercise performance outcome (countermovement effect). During the stretch-shortening cycle, the fascicles and tendons exhibit a unique behavior; much ofthe length changes of skeletal muscle occur in tendons while fascicles contract almostisometrically. The countermovement effect varies among individuals and changes throughtraining (or practice). The dynamics of muscle fascicles and tendons may underliethe effects of interindividual differences and training on the countermovement effect.
