Formula to figure out level of intensity

220 minus his/her age, times 65% and then 85%

Cardiorespiratory Endurance Chart

5-7 sessions per week, 65-85% or 4 MHR or RPE, 60+ minutes, activity type; various: running, swimming, biking, etc.

FITT Principle

A formula in which each letter represents a variable for determining the correct amount of physical activity.

Maximum Heart Rate (MHR)

Highest number of times the heart can beat in one minute

Intensity

How hard an activity is performed each session. Cardiorespiratory Endurance -- between 65% and 85% of the maximum heart rate or an intensity level (RPE) of 4.

Time

How long an activity is performed each session Cardiorespiratory Endurance -- time spent working out is at least 60+ minutes per day.

Frequency

How often an activity is performed each week. Cardiorespiratory Endurance -- 5-7 sessions per week

Cardiorespiratory Endurance

The ability of the heart, lungs, blood and blood vessels to supply enough oxygen and necessary fuel to the muscles during long periods of physical activity.

How is physical performance enhanced by cardiorespiratory endurance using the FITT Principle?

The heart becomes stronger and is able to pump more blood with each beat, which means the heart can beat at a slower rate and circulate the same amount of blood. Can preform more vigorously and for longer periods of time without becoming tired.

Type

Which activities are chosen Cardiorespiratory Endurance -- that increases the heart rate to the appropriate intensity
