Muscle tone is ________. the condition of athletes after intensive training the ability of a muscle to efficiently cause skeleta
Sedbober [7]

Answer:

a state of sustained partial contraction

Explanation:

Simply said, muscle tone means that there is a sustained tension in a muscle wile in a determinate posture. The muscle tone enable us to mantaing our bodies in a posture fit for resting or for also working, like sitting, being stand up or in a couch or sleeping. The changes in the muscle tones make us able to move. So contractions will follow depending what activity we are engaged on, as a continous and passive partial contraction of muscles change following changes in direction.

Muscle tones have contractions that do not produce enough tension to move, buy they keep it tense and firm.

Thererefore the tension is balanced and resting muscle tone balances bones and joints.

See below :)

In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state. It helps to maintain posture and declines during REM sleep.
