Answer:

When skeletal muscles are trained by adding physical stress to them, this is called progressive resistance training (PRT).

Explanation:

During PRT, muscles are exercised against an <em>overload or resistance</em>; the overload is gradually increased in order to allow muscles to adapt. This allows for progressive strength increases over time.

Muscle fatigue is defined as a reduction in the ability to produce force due to exercise. This comprises:

  • peripheral fatigue- due to changes at the junction between motor neurons and the muscle.
  • central fatigue- caused by a reduced capacity to use voluntary force in relation to the capacity to use involuntary force
  • and muscle damage- this is associated with several issues at the cellular level such as disrupted membranes and cytoskeletons; and tissue damage via torn muscle fibers, and collagen.

Overall, these may affect muscle fiber activation and the amount of force they are capable of producing- i.e. sustained strength. However, muscle fatigue  can be greatly reduced via the maintenance of PRT. Also, apart from strength gains, PRT is <em>used for weight loss and muscle building</em>; common tools used in PRT include <em>free weights, elastic bands and exercise machines. </em>

I agree and disagree. I disagree because with out meat she would not have protein , but if she ate eggs, tofu, and cheese she would have the protein.

So its healthy if she eats the eggs todu and cheese, but its unhealthy ( for her muscles ) to not have any protein.
