PE Test 4 Section 3

The cardiovascular system helps move hormones throughout the body during exercise.

Which of the following physiological effects occurs as a result of increased exercise? A. the body's blood pressure decreases throughout the body B. the blood flow is directed towards the large organs C. the levels of oxygen in the body decreases D. the volume of blood pumped by the heart increases

Increasing cardiorespiratory fitness levels is difficult for experienced athletes because __________. A. they are not motivated to increase their levels of cardiorespiratory fitness B. they cannot commit the training time to increase their cardiorespiratory fitness C. they have already achieved high levels of cardiorespiratory fitness D. none of the above

The maximum oxygen uptake is known as the __________. A. VO2 max B. OX max C. OX3 max D. VO max

Why are slow-twitch muscles more beneficial than fast-twitch muscles for cardiorespiratory fitness? A. Slow-twitch muscles are longer and thicker than fast-twitch muscles. B. Slow-twitch muscles need less blood to contract than fast-twitch muscles. C. Slow-twitch muscles need more recovery time between exercise sessions than fast-twitch muscles. D. Slow-twitch muscles are able to use oxygen more efficiently than fast-twitch muscles.

As a person ages, his or her levels of cardiorespiratory fitness tend to __________. A. improve B. decline C. stay the same D. none of the above

Your maximum oxygen intake is a measurement of the ability __________. A. to transport oxygen to your muscles B. of the muscles to absorb oxygen C. of the muscles to create energy from oxygen D. all of the above are measured by maximum oxygen intake

Optimal cardiorespiratory fitness requires a BMI of __________. A. 18.5 to 24.9 B. 25.0 to 29.9 C. 30.0 to 39.9 D. 40.0 to 49.9

During exercise, the oxygen concentration in the blood increases to twice that of resting levels.

Female gains in body fat starting around puberty can result in a cycle of diminished physical fitness.

As people age, they become unable to control their cardiorespiratory fitness levels.

During exercise, an individual's heart rate tends to increase steadily until __________. A. the athletic activity is completed and the cool down begins B. the individual begins to use advanced breathing techniques C. a level of consistent intensity has been reached D. none of the above

For a typical person who leads a sedentary lifestyle, a typical maximum oxygen intake level would be __________. A. 20 ml/kg/min B. 35 ml/kg/min C. 50 ml/kg/min D. 70 ml/kg/min

The maximum oxygen intake level can only be measured using the multistage fitness test.

How is blood pressure in the body affected by exercise? A. systolic pressure increases, diastolic pressure decreases B. systolic pressure decreases, diastolic pressure remains constant C. systolic pressure increases, diastolic pressure remains constant D. systolic pressure remains constant, diastolic pressure increases

Females are unable to maintain a high level of cardiorespiratory fitness.

It is possible to improve cardiovascular fitness without increasing respiratory fitness.
