What happened to the plasma levels of carbon dioxide during exercise why?
it increases
Does the insulin levels in your body drop during prolonged exercise?
yes
What happens to the levels of carbon dioxide and water during aerobic exercise compared to their levels when the performer is at rest?
eutrophication
What happens to the BP of a poorly-conditioned individual after a vigorous exercise compared to a well-conditioned athlete?
"BP is indirectly indicated by intensity or exertion levels. The systolic BP is expected to rise because of the increase in cardiac output. Diastolic BP is expected to remain equivalent to resting levels or decrease during exercise indicating an increase of vasodilation and an opening of the capillary beds." (Collegetermpapers)
Why do we feel hungry or hungrier after exercise?
During exercise the body depletes its glucose reserves and blood sugar levels fall.
How do haematocrit levels change during and after exercise?
Haematocrit levels usually increase during and after exercise due to higher blood pressures forcing fluid out of cells therefore reducing plasma volume and producing a false haematocrit reading.
What effect does rapid exhalation of CO2 during excerise have on the concentration of H2CO3 in the blood?
During exercise it has no effect. Without the exercise it would lower the CO2 (or H2CO3) levels.
When low oxygen levels occur during exercise what end product is glucose converted into?
Energy
Sound pressure levels comparison?
Comparison of Sound Pressure and Sound Intensity Levels. Scroll down to related links and look at "Comparison of Sound Pressure and Sound Intensity Levels".
What has the author Gracie J Purvis written?

When low oxygen levels occur during exercise glucose is converted into what stable end products?
Energy
What happens to your heart rate when you excercise?
Depending on how light or heavy exercise is will depend on the change that occurs. Typically during exercise heart rate will increase. This is in order to increase blood flow to the working muscles to allow for increased respiration - in order for the muscles to work efficiently. Therefore the more strenuous the exercise, the more your heart rate will increase. Blood pressure will also increase during exercise and again depends on intensity levels. During exercise such as running/cycling/swimming systolic pressure will increase progressively whereas diastolic pressure will increase only slightly. During weight lifting exercises, both systolic and diastolic pressures will rise. Obviously these effects will vary from person to person, depending on age, gender, exercise level, exercise intensity etc. etc.
