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
Main topic
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
