Matters of the heart
Oxygenated blood enters this part of the heart
what is the left atrium
Working in this zone primarily targets glycolysis and cannot be maintained for extended periods of time
what is zone 4
Carbon dioxide rich blood is traveling via this type of blood vessels back to the heart
what are veins
this equals end diastolic volume minus end systolic volume
what is stroke volume
this structure is the power house of the cell
what is the mitochondria
Deoxygenated blood leaving the heart is heading towards this organ
what are the lungs?
the higher this is the longer and more effectively can one use aerobic energy systems and is a great predictor of success in long distance events
what is anaerobic threshold
these vessels have the highest pressure and injury to those can lead to fatal injury
what are arteries
This is the product of stroke volume and heart rate
what is cardiac output
this energy system is located in the mitochondrial matrix and produces two ATP, six NADH2, two FADH2two QH2(ubiquinol) and four CO2 per one molecule of Glucose and really likes to go around in a circle
What is the Krebs cycle
the size of this chamber increases following cardiovascular training.
What is the left ventricle
this unit measures the volume of carbon dioxide expelled divided by the volume of Oxygen consumed
what is RQ
this blood vessel receives oxygen rich blood straight from the heart
what is the Aorta
these units are used to measure relative Vo2max
what is ml/kg/min
Following endurance training increases in this type of muscle fibers are likely to occur
what are type one muscle fibers / slow twitch
one of the adaptations to resistance training is increased thickness of this layer surrounding the different chambers of the heart
What is the Myocardium
this is the RQ value when 50% of energy is produced via fat and 50% is produced via sugar
what is .85
the higher this is the harder the left ventricle need to work in order to eject blood towards the systemic circulation
what is blood pressure
This equation is the product of cardiac output and AVo2 difference and is used to calculate Vo2Max
What is the Fick equation
one of the cellular adaptations seen due to cardiovascular training is an increase number of this structure where aerobic energy systems are located
what are mitochondria
this area of the heart in known as the "pace maker"
What is the sinoatrial node
the biggest contributor to increases in overall capacity, cardiac output and ultimately VO2max following zone training is due the increases in this factor measuring the amount of blood ejected from the heart
What is stroke volume
increases in branching of this type of vessels as a result of cardiovascular training promotes increase oxygen delivery to various tissues.
What are Capillaries
This unit is the result of dividing Stroke volume by end diastolic volume and is a measure commonly used in cardiac rehab or when estimating the risk of heart failure
what is ejection fraction
this is the amount of ATP produced by the ETC not including Gylcolysis and the Krebs Cycle
What is 34
