Cardiorespiratory chronic response

Blood

Decrease blood viscosity

Increase red blood cell

Increase blood plasma

Blood Flow

Increase blood flow

Increase blood volume

Increase in blood redistribution

Increase opening of existing capillaries

Increase capillarization

Stroke Volume (SV)

Increased in heart contractility

Greater diastolic filling time -> decreased HR

Increased in EDV -> increased in blood plasma

Increase SV during rest, submaximal, maximal exercise

Main toc

Main topic

Blood Pressure

Decrease systolic BP

Increase arteriole dilation at active muscle

Chronic exposure to pressure

Submax endurance training

Cardiac Output (CO/Q)

Increase during maximal exercises - Increase in SV

Slight change during rest & submaximal exercises

Chronic exercise (heart rate)

Decrease recovery HR (faster)

Decrease steady state HR (faster)

Decrease maximal HR

Optimum SV to maximize CO

Decrease submaximal HR

More efficient heart

Decrease resting rate

Increase parasympathetic response
