CARDIORESPIRATORY CHRONIC RESPONSE

BLOOD PRESSURE

DECREASED SYSTOLIC BLOOD PRESSURE

SUBMAX ENDURANCE TRAINING

CHRONIC EXPOSURE TO PRESSURE

INCREASE ARTERIOLE DILATION AT ACTIVE MUSCLE

BLOOD FLOW

INCREASED BLOOD FLOW

INCREASED CAPILLARIZATION

INCREASED OPENING OF EXISTING CAPILLARIES

INCREASED IN BLOOD REDISTRIBUTION

INCREASED BLOOD VOLUME

CARDIAC OUTPUT (CO/Q)
(VOLUME OF BLOOD PUMPED PER STROKE)

CO/Q = SV x HR

SLIGHT CHANGE DURING REST & SUBMAXIMAL EXERCISE

DECREASE DURING MAXIMAL EXERCISES
(INCREASED IN SV)

STROKE VOLUME
(VOLUME OF BLOOD PUMPED PER STROKE)

SV DURING REST, SUBMAXIMAL,
MAXIMAL EXERCISES: DECREASE

INCREASED IN EDV

INCREASED IN BLOOD PLASMA

GREATER DIASTOLIC FILLING TIME -> DECREASED HEART RATE

INCREASED IN HEART CONTRACTILITY

HEART RATE

RESTING HEART RATE: DECREASE
(INCREASE PARASYMPATHETIC RESPONSE)

SUBMAXIMAL HEART RATE: DECREASE
(MORE EFFICIENT HEART)

MAXIMAL HEART RATE: DECREASE
(OPTIMUM STROKE VOLUME TO MAXIMIZE CO)

STEADY STATE HEART RATE (FASTER): DECREASE

RECOVERY HEART RATE (FASTER): DECREASE
(MORE EFFICIENT HEART)

BLOOD

INCREASE BLOOD VOLUME

INCREASE BLOOD PLASMA

INCREASE RED BLOOD CELL

DECREASE BLOOD VISCOSITY
(INCREASE BLOOD FLOW)

LUNG VOLUME

INCREASE TIDAL VOLUME

INCREASE DURING MAXIMAL EXERCISE

INCREASE VITAL CAPACITY

MAXIMUM AMOUNT OF AIR EXPELLED AFTER MAXIMUM INSPIRATION

DECREASE RESIDUAL VOLUME

AMOUNT OF AIR THAT REMAINS IN THE LUNGS

A-V O2 DIFFERENCE

INCREASE A-V O2 DIFFERENCE

DUE TO INCREASED O2 EXTRACTION AT THE BODY

INCREASED OXIDATIVE CAPACITY
