What equation would accurately allow you to calculate an athlete's maximum heart rate (HR_max)

• HRmax = 207 – (0.7 x age in years)

• HRmax = 208 – (0.7 x age in years)

• HRmax = 207– (0.6 x age in years)

• HRmax = 208 – (0.6 x age in years)

Which of these statements is FALSE in terms of steady state heart rate?

• The suboptimal heart rate for meeting circulatory demands at a given submaximal intensity

• The point on the graph where the heart rate plateaus

• The optimal heart rate for meeting circulatory demands at a given sub-maximal intensity

• This is a basis for some exercise tests to find an athletes level of fitness

• Adjustment to a new exercise intensity takes about 2-3 minutes

What does capital Q stand for?

• Heart Rate

• Stoke Volume

• Cardiac Output

• Lung Capacity

Which equation is used to find Q?

• Heart Rate X Cardiac Output

• Cardiac Output X Stroke Volume

• Stroke Volume + Lung Capacity

• Cardiac Output - Stroke Volume

• Heart Rate X Stroke Volume

The average untrained person's resting Q is 5 L/Min and Q_max is 20 L/Min

• True

• False

When your VO2max has reached 100%, which option would have the highest blood pressure?

• Arms systolic

• Legs systolic

• Arms diastolic

• Legs Diastolic

During exercise, all of these organs gain an increase in blood supply except for one. Which one DOES NOT receive more blood?

• Skin

• Muscle

• Heart

• Kidneys

What is VO_2max measure?

• The max amount of oxygen that your lungs can hold at one time

• The max amount of carbon dioxide that your lungs can hold at one time

• The max amount of oxygen utilized by a person during stressful exercise

• The max amount of oxygen utilized at rest
