B. As a cross country runner its very important to warm up before I run a marathon or a long distance run or just any run in general its always something I have to do. If your do the strenuous activity without warming up your muscles will be tight and will sort of go into shock. By warming up you are releasing tension in your muscles and ligaments and getting you blood flowing. In my experience I didn't warmup once before a half marathon and had to stop about a mile in because I tore my hamstring. It strained it right off the bat and kept getting worse just because I forgot to stretch! I hope this helps!

When skeletal muscles are trained by adding physical stress to them, this is called _____.
tangare [24]

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>

Sociology!!!!<br><br><br><br> Do you think social stratification is good or bad for society?
timama [110]
<span>Social stratification is the essence of a democratic society. However, there can be drawbacks, such as the inequality of the classes. There comes a time when you have to wonder if those that are in better socio economic classes exploit those who do not have an edge in societal classes. So, to answer your question, it is both good for society in that it allows for classes to progress, and it may be bad since those in lower classes will have a harder time advancing.</span>
