Everything Flashcards
Tidal Volume
Is the volume representing the normal volume of air diplaced between normal inhalation and exhalation
Anareboic Threshold
The point during exercise where lactic acid builds up in your muscles
Mitochondria
Is where the areobic repspiration occurs
Word Equation
fuel + Oxygen —-> Energy + Water+ Carbon dixoide+ Heat
Increased Heart Rate
Is the number of beats your heart makes in one minute
Increased stroke volume
The amount of blood pumped out of the left ventricle per beat
Increased cardiac output
Is the amount of blood pumped out of the heart’s left ventricle in 1 minute
Increased blood pressure
is the measure of the pressure produced by the blood being pumped into the artieres
Increased blood flow
During exercise blood flow to the working muscles and skin increases because of increased cardiac output
Increased arterivenus Oxygen difference
Is the difference between the oxygen concentrations in the viens
Decrease blood plasma
Because of increased sweating, the blood plasma volume decreases during strenuous exercise
Increased respiratory rate
respiratory rate is the number of breaths taken in one minute
Increased Tidal Volume
Is the size of each breath taken
Increased ventilation
Is the amount of air breathed in 1 minute
Increased lung diffusion
During strenuous exercise, there is a three-fold increase in oxygen from the alveloi to the blood
Increased oxygen uptake
Is the amount of oxygen taken up and used by the body to produce energy
Cardiac Hypertrphy
Regular training increases the size of the heart
Increased stroke volume(chronic)
The heart develops larger chambers, thicker walls and improves excitability
Decreased heart rate (chronic)
Your body does not need to beat as many time to provide oxygen
Increased cardiac output (chronic)
During submaximal exercise remains constant after months of tranaing cardiac output increases due to your muscles need as much oxygen from the blood as possib
Increase vascualtion (cardiac)
Regular training over a period of months stimulates the growth of new blood vessels that feed the muscle fibre
Increased artviorvenous (chronic)
more oxygen can be absorbed from the blood into the musclesm skin as increased mygbolin level and an increased size of mitrochondira
Lower blood pressure (chronic)
blood pressure reduced towards normal both rest and exercise because of improved ascualr
Lung capacity (chronic)
Masures the amount of additional air that can be exhaled
Increased VO2 max (chronic)
Training, indicated the amount of oxygen consumed
Anareboic Threshold (chronic)
decreased lactic acid and intensity of which lactic acid builds up in the body faster
Why is AV02 is much greater during exercise than rest
Your muscles are working harder than normal and as a result require more energy
Increases muscular oxygen demand and ATP energy used by your muscles is generated with the aid oxygen
Anareobic energy system
is without oxygen
Areobic energy system
With oxygen
ATP-PC
Provides immeadiate energy
Lactic Acid
Produced during the anareobic metobolisim of glucose
Areobic
Produces large amount of energy althogha at lower intensity
Order
ATP-PC, LACTIC ACID AND AREOBIC
Food sources used first
Carbs, fats, proteins
Heart rate measuring
The slower your heart rate is the fitter you are and it will increase in prodportion of the intensity of the exercise
Using a heart rate monitor
Taking your pulse
White muscle fibres
Thicker, perform fast and strenuous work for a short peiod of time, fast contraction, lactic acid build up
Red muscle fibers
Thinner, slow and sustained contraction, used for long distance, No lactic acid
The imortance of having an areobic threshold
Build up of lactic acid threshold team sport
The quicker the recovery after a high intensity exercise is the effecieny of the body in removing oxygen from the air absorbing it into the body and repaying the muscles oxygen.
VO2 factors
Gender, Genetics, age, Areboic fitness, Body size
Lactic acid build up
Produces as much as we can breath out which produces lactic acid CHO AND H2O no need to slow down
