1 MET = 3.5 ML O 2/KG/MIN Ideal blood pressure 120/80mmHg Hypertension 140/90mmHg VO2= Q * (CaO2 - CvO2) (Q is cardiac output) Q= HR*SV 1 LO2 = 5 KCAL (at steady state equilibrium only) RER (respiratory exchange ratio) = RQ (respiratory quotient) AT STEADY EXERCISE RER: VCO2(EXPIRED) / VO2(CONSUMED) [same equation for RQ]. Ve (ventilation): TV * f (BREATHING FREQUENCY), TV STANDS FOR TIDAL VOLUME. age-predicted heart rate maximum = 220-age Termination heart rate =220-age*85% BMI= Weight (kg)/Hieght m^2 kg=2.2lb inch=2.54cm On the last day of class she gave hints about certain things to pay attention to in her lectures. Some of the examples she gave were: a) know the "A public safety.." definition on the third page of her first lecture “A public safety task is a task in which the safety of the worker, a co-worker or the public may be compromised by the failure to complete or inefficient performance of the required task.” b) the red box in the same lecture, which is on the fourth page of the first lecture • Legal Precedents; in particular the 1999 Supreme Court of Canada’s Meiorin Decision, which led to • The 2000 Consensus Forum on Establishing BFORs for Physically Demanding Occupations • 2004 Amendment to the Criminal Code of Canada c) 3 step process to prove a standard qualifies as a BFORhe thanks rivky what limits vo2 max? SV (stroke volume) and blood volume. KINE 1020 DISCUSSION (Notes for infectious diseases and respiratory system added, check the link).
