laila [671]3 years ago

The human heart works like a pump sending blood around your body to keep you alive. ... This blood delivers oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products. Your heart and circulatory system works together to deliver blood to your organs so they can function.

The ability of the muscle to exert maximal effort in a brief duration.
slavikrds [6]

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.
