Document Summary
Unit 19 bpk lab study questions: you have been asked to set up a lab for testing maximum oxygen consumption. Itemize all of the equipment that you will need. Gas volumes vary under different conditions of pressure/temp. Necessary to account for varying factors therefore all volumes are corrected . 0 degrees celcius, 1 atm pressure, free of h20 vapour. Partial pressure = pressure exerted by individual gas in mixture. Blood lactate levels 8. 0mm/l or greater 3-5 mins after exercise. Subject fatigue/unable to continue: describe the shape of a typical graph of vo2 versus power output and give a physiological explanation for shape of this graph. Increases linearly, beings to plateau when subject reaches vo2 max. Plateau = intensity rises w/o rise in o2 consumption. 6. describe the shape of a typical graph of heart rate versus vo2 and give a physiological explanation for shape of this graph. Positive correlation b/w hr & o2 consumption.
