Cardiorespiratory Endurance and the FITT Principle

You can improve or maintain how well heart and lungs work by applying the FITT Principle for

• flexibility

• muscular strength

• muscular endurance

• cardiorespiratory endurance

How long a cardiorespiratory endurance workout session lasts is called

• frequency

• intensity

• time

• type

To improve cardiorespiratory endurance the frequency of the workout sessions should be

• 2 to 3 sessions per week

• 1 to 3 sessions per week

• 3 to 5 sessions per week

• 5 to 7 sessions per week

Cardiorespiratory endurance is best described as the ability of the

• joints and bones to move through a full range of motion

• muscles to work over a long period of time

• body to burn calories efficiently

• heart and lungs to work efficiently to supply oxygen to the muscles

Intensity during a cardio endurance workout means

• how often an activity is performed

• how hard an activity is performed

• how long an activity is performed

• where an exercise is performed

Increasing the speed or pace of swimming laps affects the

• frequency

• intensity

• time

• type

Which FITT Principle variable is changed when you increase the length of a run from 1 mile to 2 miles?

• frequency

• intensity

• time

• type

What is the FITT Principle recommendation for the time that will give you the most benefit from your cardiorespiratory workout?

• 60 minutes

• 30 minutes

• 20 minutes

• 5 minutes

According to the FITT Principle, how intense should your cardio endurance exercise be?

• 65% to 85% of the max heart rate or RPE of 4

• 50% to 65^ of the max heart rate or RPE of 3

• 35% to 50% of the max heart rate or RPE of 2

• Above 85% of the max heart rate or RPE of 5

Frequency should be how many sessions per week

• 3-4

• 5-7

• 1-2

• 2-4
