Moledule 1 Flashcards
Topic 1 (VO2 max) and Topic 2 (Intro to exercise physiology, biochemistry and energy) (29 cards)
Fick Equation - what is it and what does it calculate?
VO2 = Q x (CaO2 - CvO2) / VO2 = (heart rate x stroke volume) x (arterial O2 content - venous O2 content)
Maximal rate of oxygen consumtion
The Gas Laws have 3 properties, what are they?
Volume, pressure and temperature
Define VO2
Is the volume of oxygen that the body can take in, transport and utilize during exercise or at rest
Define VCO2
Is the volume of carbon dioxide that the body produces and exhales during exercise or at rest
Define VE (dot on top)
Is the volume (L) of expired air every minute also called minute ventilation
FeO2
Is the fraction of oxygen (measured by the O2 analyser) in expired air
FeCo2
Is the fraction of carbon dioxide (measured by the CO2 analyser) in expired
Hans Rudolph Valve Assembly what is it?
The Hans Rudolph Valve is a piece of equipment that is used during oxygen consumption tests
What are the normative data for VO2 max for untrained vs trained individuals (define difference between male and female too)
Untrained female 25 - 35 mL/kg/min
Untrained males 35 - 45 mL/kg/min
Trained individuals it depends on their sport and what they train for if it was cross country skiing then it would be quite high as those atheletes tend to have extremely high VO2 max while sprinter would still be above average but they would be closer to 60 -70 as they don’t need a high VO2. Obviously though male atheltes would have higher Vo2 max compared to females
Gas laws and respiratory conversions - what are they?
Calculations made by using gases to estimate oxygen consumption (metabolic rate) the output is an APPROIMATION unitl the effect of temp and pressure are considered
Can you describe physiology and exercise physiology and its role in exercise science?
Physiology is the study of how organisms, organs, tissues and cells, function - the physical and chemical processes that maintain life
Exercise physiology is the study of how exercise influences the body and how it the systems interact with each other. Either short term or longer term.
This plays a role in exercise science as in exercise phyisology we learn about the inside of our bodies and how they would react and change to exercise. This includes how someone untrained vs trained, male or female, disorder or healthly bodies would take on exercise.
Define homestatsis
Explain postive feedback
Explain negative feedback

Ionic bonds
commin molcules
compound and ions in the human body

enzyme actions
acid-base pH scale
biological buffer
chemical substrats such as carbohydrates, lipids and protein
