Read each question and the respective answer options slowly and carefully. Select the best answer and when you are ready, click the “submit by e-mail” button. Then follow the instructions in the pop-up window (see also bottom of this file).

1. Several properties of water make aquatic exercise both safe and therapeutic, and different from exercise on land. Fluid (water) pressure on immersed body parts

← squeezes the muscles so they have to work harder against the resistance of the water.

← squeezes the thoracic cavity and makes the heart work harder to circulate blood through the body.

← increases partial pressure in the lungs and thus facilitates breathing.

← decreases venous blood pooling, edema and swelling and facilitates blood flow (return to heart).

2. Several properties of water make aquatic exercise both safe and therapeutic, and different from exercise on land. The water’s natural resistance

← makes movements in water generally slower than on land, so you don’t work as hard during exercise.

← makes movements in water generally slower than on land, so you can’t get your heart rate up to burn fat during exercise.

← makes movements in water generally harder than on land, so you can’t get your heart rate up to burn fat during exercise.

← makes movements in water generally harder than on land, so you work harder during exercise.

3. Gravity is the force on Earth which pulls all objects toward its center. Buoyancy is a very characteristic force that acts upon all bodies submerged in a liquid, acts in the opposite direction of gravity and causes an object to become lighter in the water. Buoyancy is an application of

← Archimedes’ Principle.

← Archbishop’s Law.

← Newton’s Law.

← Eureka’s Principle.

4. A person is more buoyant floating in

← Horizontal position (flat on front or back) with head lifted out of the water.

← Vertical position (head up and feet down) with face lifted out of the water.

← Horizontal position (flat on front or back) with air in lungs.

← Horizontal position on front, hugging knees to chest and tucking chin in.

5. Several properties of water make aquatic exercise both safe and therapeutic, and different from exercise on land. Buoyancy of the water helps you to "take a load off" your joints. When swimming, a human body will experience

← Less than 10% of its weight on land.

← 10-20% of its weight on land.

← 20-30% of its weight on land.

← Only about 40% of its weight on land.

6. The human body uses a variety of mechanisms to regulate temperature, specifically

← Heat conduction, convection, radiation, evaporation

← Shivering, goose bumps, sweating, fever

← Heat transfer through the skin, the mucous membranes, into the air and from the air

← Metabolic system, cardio-vascular system, muscle system and respiratory system

7. The human body generally loses heat at a different rate in water than it does in air of the same temperature:

← Double as fast

← Four times faster

← Twelve times faster

← Half as fast

8. The following swim strokes are considered “back strokes”:

← Back Crawl, Trudgen Crawl

← Elementary Backstroke, Butterfly

← Back Crawl, Elementary Backstroke

← Elementary Backstroke, Trudgen Crawl

9. The following swim strokes have symmetrical arm and leg action, i.e., both arms and both legs perform the same section of the stroke simultaneously.

← Breast Stroke, Back Stroke.

← Back Stroke, Elementary Backstroke.

← Breast Stroke, Elementary Backstroke.

← Breast Stroke, Front Crawl.

10. The following swim strokes have alternate arm and leg action, i.e., one arm is in a different section of the stroke than the other arm (same for the legs).

← Back Stroke, Front Crawl.

← Butterfly, Freestyle

← Breast Stroke, Front Crawl

← Elementary Backstroke, Front Crawl.

11. Which of the following “cues” best describe the Front Crawl?

← Body roll side to side, look where you are going, inhale as fast as possible, one arm out of water, other arm pulling under water, whip kick

← Swim on front, breathe to side, windmill arms, whip kick

← Body roll side to side, look at bottom of pool, blow bubbles under water & take a breath from the side, high elbow (shark fin) on recovery arm, flutter kick

← Swim on back, breathe when needed, windmill arms, flutter kick

12. You should never dive (enter the water head-first) in the following situation:

← There is a “No Diving” sign.

← You do not know how deep the water is.

← The water is less than 5 feet deep.

← All of the above

1. Fill out this “OnLineExam.pdf”, file and double-check that it displays the selection you made for each question.

2. Click “Submit e-mail” button.

3. A “How to Send the Data File” window should pop up. Follow instructions (Step 1, Step 2, Step 3)

4. You don't have to print the file, but you can if you want to.

5. The data file you saved in Step 1 has a “.xml” extension. That is the file you need to attach to the e-mail you send me on or before the due date.

6. Remember to put your class ID and “On-Line Exam” into the subject line, and to attach the “.xml” file.

7. I will let you know whether your data has arrived in my inbox. Please do not wait until the last minute - leave yourself some time in case your data did not get submitted on your first try.

Good luck!
