F.I.T.T. Principle

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

• muscular endurance
• muscular strength
• flexibility
• cardiorespiratory endurance

Intensity during a cardiorespiratory 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

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

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

How long a cardiorespiratory endurance workout session lasts is called

• frequency
• intensity
• time
• time

If you are walking at a pace that causes your heart to beat less than 50% of its maximum heart rate, which FITT principle variable do you need to change to improve your cardiorespiratory endurance?

• 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

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

• 65% to 85% of the maximum heart rate or RPE of 4
• 50% to 65% of the maximum heart rate or RPE of 3
• 35% to 50% of the maximum heart rate or RPE of 2
• Above 85% of the maximum heart rate or RPE of 5

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
