Answer to Question 1

Correct Answer: 1, 3, 5

Isotonic exercises increase tone, and involve activities such as running, walking, and cycling. Resistive exercises such as weight lifting do not increase muscle tone. Isometric exercises include those that affect muscle tension but do not result in muscle or joint movement. Isometric exercises are useful for strengthening abdominal, gluteal, and quadriceps muscles, for maintaining strength of immobilized muscles, and for endurance training. Examples of isometric exercise would include tensing of thigh muscles and extending the arms and pushing against a wall. Cycling is an example of isotonic exercise which increases muscle tone.

Answer to Question 2

Correct Answer: 3

The recommendations for physical activity for adults are: moderate-intensity physical activities for at least 2 hours and 30 minutes per week or 1 hour and 15 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate- and vigorous-intensity aerobic activity. Aerobic activity should occur for at least 10-minute episodes throughout the week. Only the adult who walks briskly is meeting the criteria of moderate-intensity physical activities for at least 2 hours and 30 minutes per week or 1 hour and 15 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate- and vigorous-intensity aerobic activity. The weight lifter is not exercising the minimum number of hours per week. The 42-year-old who is walking at a slow pace is not meeting the minimum criteria for moderate exercise. The swimmer is only exercising twice per week for a total of 40 minutes.
