1. Work may be expressed as foot-pounds, kilogram–meters, and joules. In essence then, to measure work one needs to know the weight of an object and the

A. horizontal distance through which it moved. B. vertical distance through which it moved.

C. time it took to move it.

D. horizontal distance through which it moved and the time it took to move it.

2. The immediate source of energy for all body processes, including muscle contraction, is

B. The 100 meter dash C. The 800 meter run D. A 5 kilometer run

5. The oxygen system

A. produces ATP in rather large quantities from other energy sources in the body.

B. involves aerobic processing of carbohydrates to some extent, with major utilization of protein. C. is used primarily in sports that demand strenuous exercise.

D. depends upon reactions that occur in the nucleus of the cell.

6. Which of the following is an example of catabolism?

A. Increased muscle mass gained through weight training

B. Constructive metabolism

C. The changing of muscle glycogen to muscle glucose

D. The better use of oxygen following endurance training

7. The elevation of the metabolic rate that occurs after ingestion of a meal is

A. increased significantly by the ingestion of fat.

B. accountable for less than 3 percent of the total daily energy expenditure. C. referred to as dietary-induced thermogenesis or thermic effect of food. D. significantly higher in obese subjects when compared to lean subjects.

8. The resting energy expenditure is

A. increased when the ratio of body surface area to body weight is decreased. B. higher during adolescence than during adulthood.

C. decreased when an individual is exposed to the cold.

D. 25 percent lower for a female when compared to that of a male.

9. All of the following are laboratory techniques used to measure the role of the lactic acid system in exercise EXCEPT

B. the steady-state threshold. C. maximal oxygen uptake. D. onset of blood lactic acid.

10. Which of the following statements about energy expenditure is INCORRECT?

A. The cost of running a given distance does not depend on the speed of movement

B. Hand weights seem to increase energy expenditure only when used at slower speeds

C. Swimming a given distance takes about four times as much energy as running that distance

D. The use of hand weights may exaggerate the blood pressure response
