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>
Hi !
<em>Although usually diagnosed in adults, which of the following diseases is now being diagnosed in young people?</em>
C. Type 2 diabetes
The correct answer is:
C. Four food groups
Treating a person's mental disorders will reduce suicide risk.
All of the other options can be dangerous for those suffering from depression or who are suicidal.
The correct answer is: consuming multiple servings of a product affects the nutritional values listed on the label by<em> doubling, or even tripling the amount of nutrients and calories consumed</em>.
Most packaged foods, such as potato chips, contain nutrition labels that generally look like this (refer to attached image). As you can see, this label lists the amount of calories and nutrients (carbohydrates, fats, sodium, etc.) found in one serving of chips- which is 1 ounce, or 15 chips. This serving size is fairly small, however, it contains 160 calories (with 60 grams of fat and 15 grams of carbohydrates). As the question states, packaged foods consumed in one sitting are often listed as multiple servings on the labeling; so if a person consumes 45 chips, he or she would be consuming three servings of the chips. This entails consuming 480 calories, instead of 160 calories from one serving.
Thus, consuming multiple servings of a product affects the nutritional values listed on the label by doubling, or even tripling the amount of nutrients and calories consumed.
