cardiorespiratory fitness

what is cardiorespiratory endurance/fitness

the measure of the pulmonary and cardiovascular system working together with the skeletal muscle to produce and do aerobic activities

cardiorespiratory endurance is the most important ….

component of health-related fitness

what are the four components of health-related fitness

body comp

CRF

muscle fitness

flexibility

what is cardiorespiratory fitness necessary for?

to sustain energy needed for daily life

• vital in CVD prevention

aerobic vs anaerobic activity

• aerobic uses oxygen to resynthesize ATP

• anaerobic does not use oxygen to resynthesize ATP

what pathways do aerobic activities use to make energy

Krebs cycle and electronic transport chain to resynthesize ATP via CHO or fat oxidation

CHO and fat oxidation occur ….

together

what determines which oxidation is used in aerobic activity

intensity and duration

intensity determines….

duration

where does ATP production happen?

in the mitochondria

when does fat oxidation typically kick in

after 2 hours

what are the different ways to gauge intensity

• HR max

• HRR

• VO2 max

• VO2R

• RPE

• talk test

what does HRR stand for

heart rate reserve

what does VO2R stand for

VO2 reserve

what does RPE stand for

rate of perceived activity

how long in aerobic activity

more than three minutes

where does anaerobic activity happen

in the sarcoplasm

how long is anaerobic activity

less than three minutes

what is the physiology of cardiorespiratory

• (breath air into the lungs),

• blood travels through the lungs where the oxygen moves from inside the alveoli to the hemoglobin in blood

• heart pumps blood carrying oxygen through the circulatory system and to organs/tissue

• cells within the tissues use oxygen to create ATP

what is the purpose of iron in hemoglobin

four irons are on the RBC, and the oxygen attaches to the iron for transportation

what is low CR endurance

heart has to work at a higher rate, less oxygen is delivered to the tissues, and you fatigue faster

what is high CR endurance

able to deliver the required amount of oxygen to the tissues with relative ease

what is the 1st way to determine the heart’s work rate

heart rate, 1st indicator of heart health

what is heart rate

number of BPM’s

• pulse

what is a normal HR at rest

60-80bpm

what is high CRF heart rate

40-60bpm

what is a low CRF heart rate

80-100bpm

what is the 2nd way to determine heart’s work rate

stroke volume

what is stroke volume

amount of blood (ml/L) the heart pumps per beat

what is the 3rd way to determine heart’s work rate

cardiac output

what is cardiac output

amount of blood pumped per minute

what is the equation for cardiac output

CO = SV x HR

what is the average person’s cardiac output

5 liters

what is VO2max

maximal oxygen uptake/consumption that can be used by the cells

what is resting oxygen uptake

oxygen used at rest

what is the average amount oxygen a person uses at rest

3.5 ml

what is one met

3.5 ml /kg of body weight/ min
