CARDIORESPIRATORY CHRONIC RESPONSE

Chronic cardiorespiratory adaptations encompass both respiratory and cardiovascular responses that result from sustained physical activity and training. The respiratory system adapts through increased lung volumes, such as vital capacity, and a reduction in residual volume, meaning a greater capacity for air exchange.

CARDIORESPIRATORY CHRONIC RESPONSE

CARDIORESPIRATORY CHRONIC RESPONSE

RESPIRATORY CHRONIC RESPONSE

A-V O2 DIFFERENCE
INCREASE A-V O2 DIFFERENCE

INCREASED OXIDATIVE CAPACITY

DUE TO INCREASED O2 EXTRACTION AT THE BODY

LUNG VOLUME
DECREASE RESIDUAL VOLUME

AMOUNT OF AIR THAT REMAINS IN THE LUNGS

INCREASE VITAL CAPACITY

MAXIMUM AMOUNT OF AIR EXPELLED AFTER MAXIMUM INSPIRATION

INCREASE TIDAL VOLUME

INCREASE DURING MAXIMAL EXERCISE

CARDIOVASCULAR CHRONIC RESPONSE

BLOOD
DECREASE BLOOD VISCOSITY (INCREASE BLOOD FLOW)
INCREASE RED BLOOD CELL
INCREASE BLOOD PLASMA
INCREASE BLOOD VOLUME
HEART RATE
RECOVERY HEART RATE (FASTER): DECREASE (MORE EFFICIENT HEART)
STEADY STATE HEART RATE (FASTER): DECREASE
MAXIMAL HEART RATE: DECREASE (OPTIMUM STROKE VOLUME TO MAXIMIZE CO)
SUBMAXIMAL HEART RATE: DECREASE (MORE EFFICIENT HEART)
RESTING HEART RATE: DECREASE (INCREASE PARASYMPATHETIC RESPONSE)
STROKE VOLUME (VOLUME OF BLOOD PUMPED PER STROKE)
SV DURING REST, SUBMAXIMAL, MAXIMAL EXERCISES: DECREASE

INCREASED IN HEART CONTRACTILITY

GREATER DIASTOLIC FILLING TIME -> DECREASED HEART RATE

INCREASED IN BLOOD PLASMA

INCREASED IN EDV

CARDIAC OUTPUT (CO/Q) (VOLUME OF BLOOD PUMPED PER STROKE)
DECREASE DURING MAXIMAL EXERCISES (INCREASED IN SV)
SLIGHT CHANGE DURING REST & SUBMAXIMAL EXERCISE
CO/Q = SV x HR
BLOOD FLOW
INCREASED BLOOD FLOW

INCREASED BLOOD VOLUME

INCREASED IN BLOOD REDISTRIBUTION

INCREASED OPENING OF EXISTING CAPILLARIES

INCREASED CAPILLARIZATION

BLOOD PRESSURE
DECREASED SYSTOLIC BLOOD PRESSURE

INCREASE ARTERIOLE DILATION AT ACTIVE MUSCLE

CHRONIC EXPOSURE TO PRESSURE

SUBMAX ENDURANCE TRAINING
