Answer:
In most cyclic movements, the ability of muscles to quickly relax or reduce tone and muscle strength allows for more efficient expression of agonist muscle strength during certain phases of movement.
Explanation:
Several movements are based on relatively short activities of the corresponding muscle groups (rapid individual movements or postural corrections) or alternating activations of antagonistic muscle groups (walking, running, throwing, kicking). The time required to perform most of these movements is limited and is often equal to the duration of explosive operations.
