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>
Relationships that involve sexual intercourse are filled with physical, emotional, and psychological risks. Abstinence provides teenagers the opportunity to avoid those risks. Individuals who abstain from sexual intercourse during their teenage years tend to have fewer sexual partners in their future.
FalseWith as low as 0.02 percent blood alcohol reading, moderate
effects can be felt and a weakened ability to focus on more than one thing a
time is apparent. For men weighing 160-240
pounds and women 200-240 pounds, impairment begins with 0.02 percent blood alcohol.
