Select one:

a. True

b. False

c. Children can only stimulate bone health by lifting weights in a gym setting.

2.Which of the following statements are true about physiological differences between children and adults? Select all that apply.

Select one or more:

a. Children tend to sweat less than adults do.

b. Children have a lower VO2Max than adults do.

c. Children tend to have more muscle fibers than adults do.

d. Children tend to have a greater total lung capacity than adults.

e. Children tend to have a greater maximal heart rate than adults.

3. Why does maximal cardiac output decline with age?

Select one:

a. Because bone mineral density declines.

b. Because maximal stroke volume and maximal heart rate declines.

c. Because total lung volume declines.

d. Because type II muscle fibers decline with age.

e. Because blood pressure increases with age.

Answer 1

1. Answer ; true

Reason ; It is recommended to have weight bearing exercise at these age for the bone health as like mentioned in the given statement. Weight lifting in the GYm is not appropriate at these age, running and jumping which is mentioned in the given statement is relevant one for these ge groups.

2. Answer ;

- a) Children tends to sweat less than the adults do.
- C) Children tend to have more muscle fiber than adult do
- E) children tend to have greater maximal heart rate than adults.

Reason ; The above mentioned statement are some variation that are occurs when comparing with the children and the adults. Other statement are not relevant, because those factors are higher in adults than childrens do.

3. Answer ; B) because maximal stroke volume and the maximal heart rates declines.

Reason ; One the major reason for the effect is because of decreased autonomic function that influence the stroke volume and the heart rate. If it get decreased spontaneously the output would be affected. therefore the above mentioned option would be the appropriate cause for these given condition in older age person.
