What happens to resting heart rate with training?
Decreased resting heart rate
Your heart gets bigger and stronger with training, allowing it to supply the same amount of blood with fewer beats.
What does a faster recovery rate indicate?
The faster your recovery rate, the fitter you are
Heart recovery rate is the speed at which your heart returns to resting heart rate (RHR) after exercise.
Define stroke volume.
The amount of blood pumped by your heart per beat.
What is the relationship between regular exercise and resting stroke volume?
Increased resting stroke volume
Stroke volume increases both at rest and during exercise with regular training.
What is maximum cardiac output?
The amount of blood ejected from your heart in one minute.
How is cardiac output (CO) calculated?
CO = stroke volume (SV) X heart rate (HR).
What changes occur in the size and strength of the heart with training?
Increases in size, thickness, and strength of the heart muscles.
What is the effect of improved fitness on capillaries?
Increases the number of capillaries in the heart muscle
This helps blood vessels become more elastic, flexible, and efficient.
How do red blood cells contribute to muscle performance?
They carry oxygen to the muscles
A higher red blood cell count can improve muscle performance.
What happens to resting blood pressure with regular exercise?
It drops
Regular exercise reduces blood pressure.
What is alveoli?
Tiny sacs within our that allow oxygen and carbon dioxide to move between the lungs and blood stream
What is a diaphragm?
The primary muscle used in the process of inspiration or inhalation.
What is cardiac output?
The amount of blood ejected from your heart in one minute (co)=(RSV) x (RHR)
What is stroke volume?
The amount of blood pumped per beat.
What is recovery rate?
The speed at at which your heart returns to RHR
