Its main job is to pump blood
What is the heart
Physical activity increases the efficiency of these organs that bring oxygen into the body.
What are the lungs
This is the ability of the heart, lungs, and blood vessels to supply oxygen during extended physical activity.
What is cardiorespiratory endurance
A 30-minute jog describes this part of the FITT formula.
What is time
Experts recommend participating in this type of activity several times each week to improve cardiorespiratory endurance.
What is vigorous activity
This organ brings in oxygen
What are the lungs
Regular exercise can lower the resting rate of this organ's beats due to an increased stroke volume.
What is the heart
This system brings oxygen into the body and removes carbon dioxide.
What is the respiratory system
This part of FITT refers to how often you exercise.
What is frequency
Stretching is an example of this type of activity found near the top of the pyramid.
What is Flexibility
Carries oxygen to, delivers nutrients to, and removes carbon dioxide and waste products from muscles
What is blood
Regular physical activity can help improve blood health by lowering this.
What is cholesterol
This body system includes the heart, blood, arteries, and veins.
What is the cardiovascular system
Heart rate, speed, and resistance can be used to measure this FITT component.
What is intensity
Push-ups, resistance bands, and weight lifting belong in this level of the pyramid.
What is muscle fitness
Also accepted
What is step 4
Carry oxygen-rich blood away from the heart to the working muscles
What are arteries
Muscle contractions during exercise help push blood through these vessels back to the heart
What are veins
This type of activity uses oxygen to produce energy during long periods of exercise.
What is aerobic activity
Exercising four days each week is an example of this FITT component.
What is frequency
Walking, yardwork, and house chores are all examples of this type of activity.
What is moderate activity
These carry deoxygenated blood back to the heart
What are veins
Regular physical activity helps keep these vessels flexible and clear for better blood flow.
What are arteries
Sprinting and heavy weight lifting are examples of this type of activity.
What is anaerobic activity
Running, swimming, and cycling are examples of this FITT component.
What is type
This concept describes the relationship between energy in (diet) and energy out (physical activity).
What is energy balance
